Earlier this year Cisco was in the headlines for the Zero-day vulnerabilities that were discovered in several of its devices including IP Phones, routers, cameras and switches.

The vulnerabilities that were quite exploitable were found in the Cisco Discovery Protocol (CDP), which is a layer 2 network protocol so that any discrepancies of the devices could be tracked.

Now again, Cisco has been found to be more unreliable than ever. Only this time the researchers learnt about numerous severe security vulnerabilities.

These susceptibilities could let the attackers or hackers execute “arbitrary commands” with the supposed “consent” of the user. Per sources, the affected Cisco parts this time happen to be the software, namely the Cisco UCS Manager Software, Cisco NX-OS Software and Cisco FXOS Software.

Reports reveal that the vulnerability in the Cisco FXOS and NX-OS Software admits unauthorized “adjacent” attackers into the system and lets them execute arbitrary code in order to achieve the “DoS”. (Denial of Service)

The vulnerabilities in Cisco FXOS and UCS Manager Software lets unauthenticated “local attackers” to execute arbitrary commands on the victim’s devices.

The reason for this vulnerability rises from the absence of “input validation”. The misuse of this makes it way easy for attackers to execute the arbitrary code making use of the user’s authority (which they don’t even know about) who’s logged in, per sources.

The other vulnerabilities in the Cisco FXOS and UCS Software include allowing unauthenticated local attackers to execute arbitrary commands.

A hacker could also try to send specially structures “arguments” to certain commands. This exploit if successful could grant admittance to the hacker to not only enter but also execute arbitrary commands.

All the exploitable loopholes of the Cisco software are really dangerous and critical in all the possible terms. Cisco has been in the limelight for more times than that could be overlooked. It is up to the users now to be well stacked with respect to security mechanisms.

However, understanding the seriousness of the vulnerabilities in the software, Cisco has indeed released various security updates that work for all the vulnerable software, in its Software Security Advisory.

The users are advised to get on top of the updates as soon as possible.

Windows Devices in Hospitals Vulnerable to Potential Exploits According to recent reports, hackers can exploit the vulnerabilities present in health devices, and it can prove dangerous to the health of the patients at the hospital. But, the problem could be avoided by following some simple steps. The health devices have a more likable chance to the Bluekeep exploit than any other devices connected in the hospitals. Health devices can be exploited up to 2 times, using the Bluekeep exploit. This puts both the patients and the hospital staff in danger as witnessing the current scenario, the health sector has recently been one of the primary targets of the hackers.


Therefore, the issue of cybersecurity among the health sector is one of the main concerns of the digital age. Bluekeep was first discovered in 2019, and it is a vulnerability in Microsoft RDP (Remote Desktop Protocol). The vulnerability affects Windows7, Windows8, Windows Server2008, and Windows Server2008 R2. When the news of Bluekeep vulnerability surfaced, Microsoft immediately released a security patch to resolve the issue. Various intelligence agencies, including the US NSA (National Security Advisory) and Britain's NCSC (National Cyber Security Centre), immediately informed Microsoft to fix all the security patches related to the vulnerability.

The matter of concern was that Bluekeep could be used as malware to do the same damage that EternalBlue had caused, the exploit that triggered Wannacry. In this incident, various high profile organizations were taken the victim, but the greatest attack happened on the National Health Service of UK, in which the entire networks of the hospitals were shut down. But despite various warnings, health devices that run on Windows are still vulnerable to a potential Bluekeep exploit.

According to researchers at CyberMDX, a healthcare cybersecurity company, a newly made report's data suggests that more than 20% of healthcare devices (that run on Windows) in hospitals are vulnerable to the blue keep exploit, as they have still not configured to the latest security patches. The healthcare devices include x-ray machines, anesthesia machines, ultrasound devices, and radiology equipment. If these devices are not fixed to the latest security patch, chances are that hackers could exploit them using the blue keep vulnerability. This can risk the lives of the patients and the healthcare staff.

Personal accounts of Runet users in various services, including Internet banks, turned out to be the worst protected from hackers. This is the opinion of Positive Technologies specialists.
After analyzing 38 websites of various organizations, including IT companies, government agencies, financial and telecommunications organizations, Positive Technologies employees concluded that nine out of ten web applications in Runet are vulnerable to hacker attacks.

Despite the fact that the situation has improved compared to the previous year, half of the sites contain "high-level" vulnerabilities. In 2019, there were 22 vulnerabilities per application, which is one and a half times lower than in 2018. According to Positive Technologies, the probability that data will leak from applications to the network is 68%, unauthorized access is possible in 39% of cases and authentication system weaknesses were found in 45%.

Also, hackers often hack applications in the banking sector. The protection of apps of credit organizations works only in 40% of cases.

According to experts, this is due to the fact that the dynamics of the main updates of the program is quite high. He noted that the system does not have time to “undergo full training” and automatic configuration.

Applications of government agencies turned out to be the most vulnerable to hacker attacks. Experts stressed that funding for this sector was low. At first, the tenders were won by those who requested the lowest price. And then expenses were reduced even more — by hiring students, for example.
Experts noted that it is quite difficult to protect web applications. Sometimes systems are used in monitoring mode, and real people monitor this. They have to determine whether the attack occurs or not.

“A 24-hour web service requires at least four operators, and this is from five million rubles a year ($78,700),” said Rustem Khairetdinov, vice president of InfoWatch Group. There is no way to hire such a staff of specialists in small companies and regional government agencies.

According to Radware researchers, a vulnerability (CVE-2020-2100) in 12,000+ Jenkins servers can be exploited to launch and amplify DDoS attacks to internet hosts.




The said vulnerability can also be abused and triggered by a spoofed UDP packet to launch DoS attacks against the internet server in a repeated sequence of replies that can only be stopped by rebooting the server.

 The vulnerability (CVE-2020-2100) 

CVE-2020-2100 vulnerability was discovered by Adam Thorn from the University of Cambridge. It is caused by a network discovery service, present by default and enabled in public facing servers.

Radware researchers explains, “The vulnerability allows attackers to abuse Jenkins servers by reflecting UDP requests off port UDP/33848, resulting in an amplified DDoS attack containing Jenkins metadata. This is possible because Jenkins/Hudson servers do not properly monitor network traffic and are left open to discover other Jenkins/Hudson instances”.

 “An attacker can either send a UDP broadcast packet locally to 255.255.255.255:33848 or they could send a UDP multicast packet to JENKINS_REFLECTOR:33848. When a packet is received, regardless of the payload, Jenkins/Hudson will send an XML response of Jenkins metadata in a datagram to the requesting client, giving attackers the ability to abuse its UDP multicast/broadcast service to carry out DDoS attacks.”

Although the CVE-2020-2100 vulnerability was fixed in Jenkins 2.219 and LTS 2.204.2 two weeks ago.

 “Administrators that need these features can re-enable them again by setting the system property hudson.DNSMultiCast.disabled to false (for DNS multicast) or the system property hudson.udp to 33848, or another port (for UDP broadcast/multicast),” developers from Jenkins explained.

 The danger from the vulnerability 

Pascal Geenens, Cyber Security Evangelist for Radware said, “Much like was the case with memcached, people that design and develop on the open source Jenkins project assume that these servers will be internally facing”.

But contrary to that, the Jenkins servers were exposed to the public. Nearly 13,000 vulnerable servers were distributed globally including Asia, Europe and North America to the top service providers. “Many DevOps teams depend upon Jenkins to build, test and continuously deploy their applications running in cloud and shared hosting environments such as Amazon, OVH, Hetzner, Host Europe, DigitalOcean, Linode, and many more” Geenens stated.

The researchers concluded, "Combined with over 12,000 exposed Jenkins servers globally, it creates a viable DDoS threat. "

A bug in the TastSelv Borger tax service which falls under the management of the US company DXC Technology has exposed almost 1.2 million CPR numbers of Danish citizens to the American multinational companies – Google and Adobe. The leak has been discovered by The Danish Agency for Development and Simplification for the first time, however, the researchers claim that CPR numbers along with other sensitive information have been exposed for around 5 years now.

People who have a tax liability to Denmark are allowed by TastSelv's services to see and alter their tax returns, annual statements and pay residual tax. As per the findings of the security researchers at the agency, all the exposed data was found to be encrypted and hence reportedly, Google and Adobe were not able to view the same due to encryption which barred them.

Other sources have it that in an attempt to downplay the entire incident, The Danish Agency for Development and Simplification put forth a solid confirmation on the CPR numbers being encrypted when accessed by the companies. Meanwhile, cybersecurity specialist and founder of the CSIS group, Peter Kruse asserted that Google did access those 1.2 million CPR numbers as there was no encryption, according to him the numbers were rather in plain text.

How was the glitch exploited?

It was when the users who were logged into TastSelv Borger happened to click on the text displayed as 'Correct contact information' and consequently rectified the contact information, faced an error in the app. The error triggered the process of transferring the CPR numbers to Google and Adobe, as per DR news website.

Referencing from the statement given by the government agency, “We take this kind of case very seriously. And of course, we need to be able to make sure that our suppliers handle all data according to applicable law and within the framework agreed upon with them.”

“The data received by Google is unencrypted. Google has been able to read data in unencrypted form,” he added.

“Google Hosted Libraries have been designed to remove all information that allows identifying users before logging on. Thus, no user information is shared with Google in this process.” Google told the website which first reported the incident.

The extremely well-known Cisco’s products, including IP Phones, Routers, cameras, and switches, were determined to have several severe “zero-day” vulnerabilities by researchers in the “Cisco Discovery Protocol (CDP)”, per sources.

CDP is a proprietary “Layer 2” network protocol that is put into effect in all the Cisco devices to be privy to the mechanisms of the devices.

Reports mention that a total of five vulnerabilities were ascertained out of which, four were “Remote Code Execution” (RCE) that let hackers or any other cyber-con to manipulate every single operation of the devices without any sort of consent of the user.

According to sources, one of the vulnerabilities led to a “Denial of Service” in the Cisco FXOS, NX-OS and IOS XR software that ended up damaging the victims’ networks

By exploiting the vulnerabilities effectively, numerous organizations’ and companies’ networks were smashed, costing all the affected parties heavily.

Per legitimate sources, following is the list of all the vulnerable devices in the represented categories:

The exploitation of the other four Remote Execution vulnerabilities could be in a way that a “maliciously” fabricated “CDP Packet” could be sent on the targeted Cisco devices and have their mechanisms altered.

There’s a vulnerability that could be hunted down or traced by (CVE-2020-3119). It helps the attackers to completely override the default switch and network infrastructure settings.

One of the vulnerabilities which could be traced as (CVE-2020- 3118), could help attackers gain control of the target’s router via remote code execution and use it in any harmful way they find acceptable.

Cisco’s 800 series IP cameras were vulnerable to attackers’ remote code execution. The vulnerability could be located as (CVE-2020-3110)

According to sources, in the other Cisco “Voice over IP Phone” vulnerability, an overflow in the parsing function could be exploited to access “code execution”. This vulnerability could be traced to (CVE-2020-311).

The troubles this vulnerability could cause an organization are manifold.
Acquiring access to other devices via “man-in-the-middle” attacks.
Damaging the network’s structure
“Data Exfiltration”, ranging from network traffic to sensitive information and personal phone calls, by the help of manipulated routers and switches.

Per reports, Cisco has come up with patches and the users are directed to employ them without any further delay.

Smart light bulbs can not only make the lighting in an apartment and house more convenient and cheaper but also threaten the safety of their owners.

Experts have proven that hackers can hack computers through smart light bulbs. The vulnerability in the smart home system was noticed by cybersecurity company Check Point.

Experts have discovered a way to hack computers through a lamp using a Philips smart home system. At the first stage, the virus program is downloaded to the victim's smartphone and causes the lighting to fail. Experts have noticed that the only way to fix the problem is to reinstall the app, so the user deletes the program and re-downloads it to their phone.

At the stage when the owner of the lamp connects it to the smart home system, attackers take advantage of the vulnerability in the ZigBee protocol, which Philips uses. At the moment of pairing between the lamp and the smart hub, the malicious algorithm causes an overflow of the system buffer, which bypasses the antivirus and is installed on the computer's disk. After that, the device goes under the remote control of hackers.

Check Point experts said that the study has already attracted the attention of the manufacturer of smart lamps and eliminated the gap in the system. Experts advised owners of the Philips smart home system to update their software.

Experts have found vulnerabilities in Philips smart bulbs (at the moment, the problem with these devices has already been solved), but it is possible that similar vulnerabilities are found in many other smart home devices.

Earlier EHackingNews reported that in the fall of 2019, an IT specialist from Russia and blogger Anna Prosvetova discovered a vulnerability in Xiaomi Furrytail Pet Smart Feeder. Since feeders are used when the owners leave the house for a long time, pets may starve to death. The vulnerability was discovered in the application API through which feeders are controlled.

Last week, Google has announced the cutting down of 'patch gap' in half for Chrome and the future plans of cutting it down further are also making the headlines.

Security Engineers at Google told that the 'patch gap' for Google Chrome which earlier was 33 days has now been successfully reduced to only 15 days. Some of you might be wondering what exactly a 'patch gap' means, it refers to the time frame it takes from when a security bug gets fixed in an open-source library to when that fix reaches in software which used that library.

These days, when the software ecosystem contains most of the apps relying upon the open-source modules, patch-gap plays a major role as it creates a potential security risk.

How Patch-Gap involve Major Security Risk?

As soon as a security bug gets fixed by someone in a particular open-source library, all the details related to that bug become available in the public domain. It is simply because of the open nature of the open-source libraries and projects. Now, the software which is largely dependent on these easily accessible components available in open source libraries, become vulnerable to the attacks and exploits that hackers can craft by exploiting the details regarding the security flaws.

How Patch-Gap will be Useful?

Considering the likeliness of the aforementioned possibility, if the software developers are releasing patches on a fixed release schedule which includes updates incoming every week or in a couple of months, the patch-gap here will allow hackers to set-off attacks that most software will have difficulty in dealing with.

A member of the Chrome Security team, Andrew R. Whalley said, "We now make regular refresh releases every two weeks, containing the latest severe security fixes,"

"This has brought down the median 'patch gap' from 33 days in Chrome 76 to 15 days in Chrome 78, and we continue to work on improving it," he further told.

Developers at Starbucks left an API (Application Programming Interface) key exposed to hackers with no password protection that could have been used by them to gain access to internal systems and consequently manipulate the list of authorized users. Hackers could have exploited the vulnerability in several ways which allowed them to execute commands on systems, add or remove the listed users and AWS account takeover.

The key was discovered by Vinoth Kumar who is an India security researcher, he happened to locate the open key in a public GitHub repository and responsibly reported it to Starbucks on 17th October via HackerOne vulnerability coordination and bug bounty platform. While reporting the same, HackerOne told, “Vinoth Kumar discovered a publicly available Github repository containing a Starbucks JumpCloud API Key which provided access to internal system information.”

“While going through Github search I discovered a public repository which contains JumpCloud API Key of Starbucks.” the expert himself told.

The key would have allowed an attacker to access a Starbucks JumpCloud API and hence the severity of the flaw was all the way up to critical. Colorado-based JumpCloud is an Active Directory management platform that offers a directory-as-a-service (DaaS) solution that customers employ to authorize, authenticate and manage users, devices, and applications. Other services it provides include web app single-on (SSO) and Lightweight Directory Access Protocol (LDAP) service.

The issue had been taken into consideration by Starbucks very early on, however, Kumar tends to take note of the same on October 21 and told that the repository had been taken down and the API key had been revoked. As soon as the company examined Kumar's proof-of-concept of the flaw and approved of the same, the expert was rewarded with a bounty worth US$4,000 for responsibly disclosing the vulnerability.

While commenting on the matter, Starbucks said, “Thank you for your patience! We have determined that this report demonstrates “significant information disclosure and is therefore eligible for a bounty,”

“At this time, we are satisfied with the remediation of the issue and are ready to move to closure. Thank you again for the report! We hope to see more submissions from you in the future.”

As if it wasn't enough already, the famous social networking and microblogging website Twitter has suffered yet another data vulnerability recently. In a recent data breach incident, an expert claimed that he was able to exploit a Twitter bug and used it to match more than 17 Million mobile numbers to user profiles. The list of the accounts targeted includes prominent lawmakers and officials. This hack was achieved by exploiting a bug in Twitter's Android application.


According to the reports of TechCrunch, Safety expert, Ibrahim Balic discovered that it is attainable to post complete records of created contact information via the contact upload option in the Twitter app. "If you put your contact information .i.e the phone number, the app in return, retrieve user information," says Ibrahim. The users whose phone numbers were matched were from countries like Germany, France, Armenia, Iran, Greece, Turkey, and Israel. In one particular incident, the user whose number was matched was found to be a prominent Israeli politician, reports TechCrunch.

About the Bug-
Ibrahim Balic started to alert the users of this issue 2 months earlier, through a WhatsApp group. When Twitter came to know this, the micro-blogging platform immediately obstructed his attempts. Ibrahim was able to create more than 2 Billion mobile numbers, steadily, after rearranging the numbers created, he uploaded them online via the Twitter Android application. However, the vulnerability didn't exist in the web-based Twitter app. It is yet to confirm whether Ibrahim's activity was associated with what Twitter issued in a statement earlier this week, saying it had suffered a data exploit. Twitted admitted that a malicious bug was implanted into its application by an anonymous cyber-criminal, which could've jeopardized numerous Twitterites information across the world, including Indian users. Twitter, however, did not reveal the person responsible for the exploit.

What can this Vulnerability do? 
This exploit in the Twitter android application can allow hackers to see personal information of the users, and also gives them the command of user accounts, by allowing hackers to tweet or send messages. The researcher Balic is known for exposing the security flaw in Apple's developer center in the year 2013. "We are working our best to ensure that the bug couldn't be exploited again," said the Twitter spokesperson. Twitter has faced various security issues in the past this year.

Android is vulnerable anew owing it to a new bug that goes by the name of “StrandHogg”. It is a serious issue as the bug could penetrate the entire security mechanism with a single wrong click of the user.

This bug has a special provision where it allows malicious applications and malware to pose as legitimate applications. The applications look so real that the user is unaware at all times.

The fake applications then find a way to the users’ sensitive data that too in real-time. Per reports, all the versions of Android are susceptible to this bug even the latest Android 10.

Surprisingly, the worst part about the bug is that the users would have no idea at all that they have been attacked and they’d be completely unaware of the malicious applications on their device.

Listening in on conversations and recording them, accessing login credentials, read/sending unwanted texts and even complete control of the photo album, call logs and contacts are allegedly a few of the many things the bug can do.

“StrandHogg” can let the hackers have a complete hold over the affected device’s camera which is pretty disconcerting given the hackers could turn on visuals whenever they find fit which could be a massive breach of privacy.

All of the senior police personnel have been alerted regarding the hazard. Several measures have also been scheduled to be taken along the lines of public awareness about the bug.

Things to steer clear off include pop up notifications asking permission for sending notifications, messages or other related things and applications asking to log in again despite being already logged in.

If such requests are allowed, the bug would let the hackers have almost complete access to the device from the camera to live conversations be it a cell phone or a tablet.

Other warning signs include suddenly non-functional links and permissions being asked by applications that have never needed them before.

The Home Ministry’s Cyber Crime Coordination Centre reportedly cited that over 500 Android applications are under the peril of an attack by this bug. They also released to all the states, a list of the plan of action of the bug.

Hackers can now allegedly, exploit Intel chips via voltage alterations which could lead to a messed up flow of electricity only to weaken the security mechanisms of the chips.

Two research teams from Europe and America had realized that this disruption in the voltage could cause sensitive information stored on the Intel chips to leak using the “Secure Guard Extensions” feature.

The researchers were asked to keep these facts concealed for the last half-year. Intel then sent out updates of its firmware to thwart any possibilities of attack.

“Plundervolt”, per source is the technique named by the researchers which comprises of planting malicious software on the target device to temporarily reduce the voltage of its electrical flow to the Intel chip.

The drop in voltage referred to as “undervolting” generally lets genuine users to conserve power when not needed and to vary the voltage to “overclock” the processor for more strenuous tasks.

But reportedly, by transitorily “undervolting” a processor and timing it accordingly could easily aid a hacker to make the chip dance to their tunes and falter, in turn revealing sensitive data stored within the “SGX enclave”.

Per the researchers, the CPU voltage when reduced could cause a “computation” error in the Intel chips. A “bit-flip” or a “fault injection” in the chips can change a “zero” to “one” on the SGX enclave.

In these potentially exploitable chips, if cryptographic computations are done, the “secret key” could be easily discover-able. The entire chip’s security would become times weaker, leading the data to decipher easily.

The attack in question is undoubtedly not easy to execute. It requires the target computer to already have the malware installed on it by the attacker. The SGS feature of Intel which was vastly advertised as corruption and threat proof in terms of sensitive data. This attack happens to present a startling position of compromise.

ARM Chips other than Intel’s were also experimented upon by artificially fluctuating their voltage much like “Plundervolt” to destabilize the security of the processors.

Intel chips haven’t always had a good record in ensuring security if the processors. Per reports, previous attacks “Spectre” and “Foreshadow” also abused the “speculative execution feature” of the chips way before the patched were released.

“Return-oriented programming” is another technique that could be used to exploit the chips which could make an “already planted” malware invisible to the anti-virus software.

Intel though, did send out an update for its Chips’ firmware which helps the user to freeze the voltage settings to cancel out any further possibilities of the above-mentioned attack.

Although, the way of counteracting the issue of “over-clocking” and the details as to the elaborate details of the update haven’t been sent out by Intel, yet. All that could be said is that keep the processors well updates and all patched up.

An antivirus maker discovered a bug in the decrypter application of the Ryuk Ransomware, the application "the Ryuk gang" basically provides to victims to recoup their files after they paid the ransom.

While the bug causes a deficient recuperation of certain types of documents, prompting data loss, regardless of whether the victim paid the ransom demand, the primary issue, as elaborated by the antivirus maker Emsisoft in a blog post, is that the decrypter shortens one byte from the end of each file it decodes.

The secondary issue is that the Ryuk gang's decryptor additionally erases the original encoded files, which means that the victims can't re-run the 'decryption operation' again with a "fixed" decryptor. 

While the last byte in many records is there for cushioning and is generally unused, for some file extensions those bytes contain essential data that when expelled will permanently degenerate that information and thusly prevent the document from being opened.

"A lot of virtual disk type files like VHD/VHDX as well as a lot of database files like Oracle database files will store important information in that last byte and files damaged this way will fail to load properly after they are decrypted," Emsisoft says.

"We're hoping to get the word out about this as quickly and widely as possible so that affected organizations can avoid data loss,"

Emsisoft advised the victims to connect by means of ryukhelp@emsisoft.com to have its analysts fix the decrypter they got from the Ryuk gang.

 In any case, while Emsisoft is the organization who discharged the most "free ransomware decrypters" in the past, this is a 'paid service', as it infers its experts attempting to address each decrypter partially, a very tedious undertaking.

Infections attributed to Ryuk include - manage service provider T-Systems, financial service provider ASD Audit, insulating technology manufacturer TECNOL, automation tool manufacturer Pliz, city of New Bedford (US), Tribune Publishing, managed service provider PerCSoft, healthcare provider CorVel, IT service provider CloudJumper, the city of Lake City (US), and many other more.

Numerous vulnerabilities in the four well-known open sources virtual network computing (VNC) systems have been as of late identified by Kaspersky researchers however luckily most of them have just been patched.

After breaking down the four broadly utilized open source VNC systems, including LibVNC, UltraVNC, TightVNC and TurboVNC, the cybersecurity firm says UltraVNC and TightVNC are frequently prescribed by industrial automation system vendors for associating with human-machine interfaces (HMIs).

A sum of 37 CVE identifiers has been allowed to the vulnerabilities discovered by Kaspersky in server and client software.

A portion of the defects are said to have been exploited for remote code execution, enabling the attacker to make changes to the targeted system and more than 20 of the security bugs have been thusly identified in UltraVNC.

Sometimes, the security firm noticed, the flaws were found as a major aspect of the research project were varieties of previously distinguished weaknesses. While the majority of the 37 vulnerabilities have been fixed, on account of TightVNC, however, TightVNC 1.X has been discontinued and package maintainers have not discharged any fixes, in spite of being advised of in January 2019.

Pavel Cheremushkin, a scientist at Kaspersky ICS CERT said that, Kaspersky called attention to that while a portion of these vulnerabilities can represent a genuine hazard, especially on account of industrial systems, exploitation of the server-side bugs much of the time requires verification, and the software might be structured not to allow authentication without a password.

This implies setting a strong password on the server can avoid numerous attacks. On the client-side, the best defense prescribed is to ensure that users don't associate with untrusted VNC servers.

Specialists of Russian Railways will conduct an investigation after the statement of the Habr user that he hacked the Wi-Fi network during a trip on the Sapsan high-speed train and gained access to the data of all its users in 20 minutes. According to the company, the hacked network did not contain personal data, but only entertainment content.

On Friday, November 15, user keklick1337 on the portal Habr.com was returning from Saint-Peterburg, where he visited the ZeroNights information security conference, to Moscow. The programmer became bored, and he decided to check the reliability of the Wi-Fi and easily gained access to the hidden data of Russian Railways. He noted that " the same passwords and free security certificates are used everywhere, and the data is stored in text documents."

"It is not difficult to access the data of the passengers of the train and it takes at most 20 minutes", noted the author of the post.

"The server of the information and entertainment system of Sapsan trains does not store personal data of passengers. The multimedia portal provides information and entertainment content: news of Russian Railways, movies, books, music and other information, " — said the representative of Russian Railways.

According to the spokesman, for authorization in the system, the user must enter only the last four characters of the document, which he used to buy a ticket, as well as the rail car and the seat number. These data are not personal and in accordance with the current legislation of the Russian Federation are stored on the server for no more than one day.

"The infotainment system server is not connected to the internal network of Russian Railways or other internal control services on the train, it is designed exclusively for entertainment and information topics and does not store any confidential customer data," added the company.

The Russian Railways plans to conduct a technological investigation on the fact of hacking the train system Sapsan.

Earlier, E Hacking News reported that the personal data of 703 thousand employees of Russian Railways, from the CEO to the drivers, were publicly available.

In a hacking contest held at Tokyo, a duo of white-hat hackers known as Fluoroacetate breached pass devices of some of the most popular tech companies namely Amazon, Samsung, Sony, Xiaomi and others. On the first day itself, the team won prize money of $145,000 (around 1.02 crore) and 15 Master of Pwn points which secured them a dominant lead ahead of others in the competition. The contestants receive a bounty for each successful breach and points that add on to the total ranking. However, the overall winner obtains the grand title 'Master of Pwn'.

The leading team, Fluoroacetate which comprises Hacker Amat Cama and Richard Zhu, amassed a lot of success early on as they managed to bypass five devices. Making history, the duo cracked down Sony X800G, first-ever Television exploited in the contesting history of Pwn2Own. Moving onto their next targets, Amazon Echo Show and Samsung Q60 television, the hackers employed an integer overflow in JavaScript to compromise both the devices. While hacking Xiaomi Mi 9, the duo used a JavaScript exploit to extract a picture from the smartphone. Next up on their list was Samsung Galaxy S10, which the remarkable duo slashed down by pushing a file on the phone via a stock overflow. The last contributor for the team's winning streak was Netgear Nighthawk Smart Wi-Fi Router R6700 (LAN interface).

Points and bounty distribution 

Team Fluoroacetate piled up a total bounty of $145,000 and 15 Master of Pwn points at the end of the first day at Pwn2Own, in the following order.

Sony X800G smart TV: $15,000 and 2 Master of Pwn points.
Amazon Echo Show 5: $60,000 and 6 Master of Pwn points.
Samsung Q60 smart TV: $15,000 and 2 Master of Pwn points.
Xiaomi Mi9 smartphone: $20,000 and 2 Master of Pwn points.
Samsung Galaxy S10: $30,000 and 3 Master of Pwn points.

Pwn2Own is the top computer hacking contest that was first conducted in 2007 with the purpose of demonstrating the security flaws present in widely used software and devices. The hackers gather at the contest to demonstrate vulnerabilities for a pre-set list of software and devices, to earn points on successful discoveries the hackers must ensure that all the exploits put forth at the contest are new. After the contest, the event organizers take charge of all the bugs and vulnerabilities discovered throughout the competition and subsequently hand them over to the respective companies.

After the final day of the tournament, Fluoroacetate, accumulating total prize money of $195,000, 18.5 Master of Pwn points along with a shining trophy and other goodies, has emerged victorious and as the rightful owner of the title 'Master of Pwn'. Notably, the team's most striking accomplishment has to be the bypassing of Samsung Galaxy S10 that won the duo a whopping sum of $50,000 and 5 valuable Master of Pwn points.

Russian IT specialist Anna Prosvetova discovered a vulnerability in Xiaomi Furrytail Pet Smart Feeder. Since feeders are used when the owners leave the house for a long time, pets may starve to death. The vulnerability was discovered in the application API through which feeders are controlled. The researcher believes that she has access to all such feeders, which are now active in the world.

Smart feeders work on the principle of a dispenser that gives a cat or dog a certain amount of dry food at a time. The owner of the animal can set the schedule of meals and the amount of portions in the mobile application. Thanks to this device, the animal can be left for a long time in an empty apartment, without worrying that it will die of hunger.

“I have logs running on the screen from all existing feeders, I see data on the Wi-Fi networks of poor Chinese who bought these devices. I can suddenly feed all the cats and dogs with a couple of clicks, but I can delete the schedules from the devices and not give them food. In addition, I see how much food is in the bowl now," writes the researcher. She has such a smart feeder at home.

Prosvetova did not provide a detailed description of the vulnerability because it is not yet closed. However, she reported that the feeders used a microcontroller ESP8266, which makes it possible to install special firmware on all devices.

As the programmer notes, the vulnerability in Furrytail is ideal for hackers who plan DDoS attacks: the whole process can be easily automated and scaled.

Prosvetova found almost 11 thousand of such gadgets on which she could change the feeding schedule without a password.

She sent a letter to Xiaomi with a detailed analysis of the vulnerability, indicating the method of finding it and advice on how to fix it. Xiaomi confirmed the bug in the smart feeders and promised to fix it. However, the company does not have a mechanism to reward researchers for finding vulnerabilities.

Last week, Russia-based security researcher Emil 'Neex Lerner has discovered a remote code execution vulnerability in the PHP bug tracker - classified as the CVE-2019-11043. The vulnerability allows the attackers to gain control of servers running PHP7 with NGINX and the PHP-FPM extension, simply by adding "?a=" to the URL of the website. Evidence shows that this critical PHP issue is being actively exploited by the threat actors.

Reportedly, the vulnerability did not affect all the PHP-capable servers, only NGINX servers with PHP-FPM enabled are exposed to the risk. The FPM is the PHP-FPM module which is employed for the purpose of performance enhancement and the vulnerability which lets a remote net server to execute its own arbitrary code simply by accessing a specially designed URL, resides in env_path_info in the file fpm_main.c of the FPM component.

PHP (Hypertext pre-processor) is a wide-open source general-purpose scripting language that is used in the development of Static websites, Dynamic websites or Web applications. It is one of the most common programming languages used to build websites and is focused on server-side scripting. It forms the basis for content management systems such as Wordpress and also (in a way) for more sophisticated applications like Facebook. Therefore, to realize a security vulnerability inside it remains a great deal for security researchers.

Experts believe that this security vulnerability has all the right boxes checked for marking the beginning of a storm in the cybersecurity world, it doesn't only expose to risk multiple environments but also makes it extremely convenient for attackers to exploit the vulnerability. Although one can argue that patches are available for users as a safeguard against the vulnerability, not everyone is equally updated with the workarounds.

The barricades to enter the website for hacking has been radically lowered by this vulnerability, so much so that even people from nontechnical background could potentially abuse it, according to ZDNet.

Satnam Narang, Senior Security Response Manager at Tenable, explains that "The PoC script included in the GitHub repository can query a target webserver to identify whether or not it is vulnerable by sending specially crafted requests,"

"Once a vulnerable target has been identified, attackers can send specially crafted requests by appending '?a=' in the URL to a vulnerable web server," adds Narang.

CERT/CC researchers found multiple vulnerabilities as they examined Satcom terminal Cobham EXPLORER 710 as an extension of IOActive’s findings in 2014. These new vulnerabilities could affect both the device and firmware.

These frailties could give attackers unauthentic access to sensitive information, control of the device, create or implant backdoor, DoS attack and more.

Cobham EXPLORER 710 is a portable satellite terminal, broadband global area network (bgan) through telephony. The device provides internet connection through satellite communications setting new standards for size, speed and features.

 EXPLORER 710 is a sophisticated communication tool for broadcasting, streaming and other IP based industry applications with a speed of 1 Mbps and higher. It is used in various sectors as Commercial aerospace, military defenses, space systems, SATCOM and more.

 The sat-com terminal, firmware version 1.07 is affected with 6 vulnerabilities listed below-

 • CVE-2019-9529 – Authentication Failure 

This failure arises due to the web portal having no authentication by default, this could lead to any attacker connected to the device to gain access to the portal and perform changes.

 • CVE-2019-9530 – Unrestricted Directory Access

There are no restrictions on access to the webroot directory, creating a liability as hackers can read, access or download any file in the webroot directory.

 • CVE-2019-9531 – Authentication Failure to port 5454 

This vulnerability allows attackers to connect to port 5454 through Telnet and execute 86 Attention (AT) commands, and gain illegal access.

 • CVE-2019-9532 – Text Data Exchange 

The web application portal passes the login password in cleartext, it could easily give way to miscreant to intercept the password.

 • CVE-2019-9533 – Default Login Credentials

The root password is the same for all devices, this could allow to reverse-engineer the password in all available versions.

 • CVE-2019-9534 – Validate Failure

According to CERT/CC researchers, "The device does not validate its firmware image. Development scripts left in the firmware can be used to upload a custom firmware image that the device runs. This could allow an unauthenticated, local attacker to upload their own firmware that could be used to intercept or modify traffic, spoof or intercept GPS traffic, exfiltrate private data, hide a backdoor, or cause a denial-of-service."

Apart from the above gaps in security, the researchers also discovered some configuration issues, missing security headers and problems in default wifi password ( being same as same as serial number) which are gravely dangerous to the device and leave it susceptible to cross-site scripting and clickjacking.

 The researchers said they currently don't have any practical solutions to these problems.

Yes, Bank filed a police complaint against fake news stating that misinformation was posted on social media concerning the bank's finance. The complaint was filed at Mumbai Police's Cyber cell when the investors withdrew their shares, and the capitals at the stock market hit a downfall. The bank's police complaint says that the fake news was scaring away its investors and depositors.



The rise of mobile internet in India has resulted in social tremors, with users falling prey to false information. Due to the lack of digital literacy, people are easily exposed to Fake News.

One of the biggest reasons is that fake news is usually engaging, and frightening which drives people to share them in a flash. It intends to create chaos among the general public. For a few days, some perpetrators are circulating fake news and ill-disposed falsehoods about Yes Bank on social networking sites and WhatsApp to generate fright among the bank's clients. The information seeks to present the bank in bad standing and is aimed to defame the bank's image among its clients, shareholders, and society.

"Yes Bank filed a charge by Mumbai Police and Cyber Cell on the propagation of fake news and advertising of lies about the bank's economic status on different social media platforms such as WhatsApp," said the bank in its report. The bank also asked the authorities to establish a committee of specialists to look over the issue of rumor-mongering and find the convict guilty of spreading fake news over social media platforms, they also requested the experts to find the origin of the fake news.

The bank requests its stakeholders and investors to be aware of false information. 'We assure our client that Yes Bank's financial standing is safe and reliable and would continue to be the same for a long time,' it says. It is no doubt that since the last few years, fake news has become a threat to Indian democracy and the people of India. Misinformation that is aggressively spread or shared through social media platforms causes chaos and distress among the public.
