New Chrome Password Stealer, 'CStealer' Sends Stolen Data to a MongoDB Database


The information collected by the Chrome browser including passwords, usernames, and other user credentials is being exposed to heavy risk as a new trojan known as CStealer attempts to steal the confidential data stored onto Google's Chrome browser.

Password stealer trojans include applications that tend to run in the background and silently gather sensitive information about the system such as connected users and network activity. It attempts to steal confidential information stored onto the system and the browsers like usernames, passwords and other credentials which once being stolen are sent to a specified destination by the attacker.

While the idea behind this info-stealing trojan is just like many others- which is to steal user credentials saved onto the browser's password manager, however, the fact that CStealer uses a remote MongoDB database to store the stolen data is what makes this case unprecedented and interesting.

The malware which was discovered by MalwareHunterTeam and was later analyzed by James does not compile and send the stolen data to a C2 under the author's command, rather, it is programmed to directly connect to a remote MongoDB data and utilize it to keep the stolen passwords stored, according to the findings.

As soon as the passwords are successfully stolen, the malware tends to link to the database and store the stolen data as per the network traffic created which was examined by James. In order to carry this out, the malware carries hardcoded MongoDB credentials and to connect to the database, it uses the MongoDB C Driver as the client library.

Notably, the approach is a bit more sophisticated and not as mainstream, however, ultimately it gets the agenda right as it successfully gets the credentials stolen. In doing so, indirectly it also gives a free invitation to other hackers to access the victim's confidential information as it tends to decrypt the privacy layers already. To exemplify, anyone who would examine the malware afterward, from law enforcers to security officers, will be able to retrieve the hardcoded passwords and employ them to get to the stolen data.

Chinese Smartphone Maker OnePlus Discloses Data Breach





Chinese smartphone manufacturer, OnePlus has announced a data breach where the order information including names, contact numbers, email addresses and shipping addresses of customers from its online store was exposed. However, customers' payment information, passwords, and accounts haven't been compromised in the incident. OnePlus ensured that the affected customers are being timely notified.

The company told in an FAQ that the breach took place last week and was discovered immediately. According to the officials, it was a certain vulnerability in their website which became the entry point of the attackers. However, no additional details were provided by OnePlus.

"We took immediate steps to stop the intruder and reinforce security, making sure there are no similar vulnerabilities. Before making this public, we informed our impacted users by email. Right now, we are working with the relevant authorities to further investigate this incident." the company said in the FAQ.

As a security measure to ensure there exists no similar security vulnerability, OnePlus thoroughly examined the
website. Furthermore, the company is making efforts to upgrade its security program which included partnering with a world-renowned security platform next month. The company told that it would be launching a bug bounty program by the end of this year.

In the OnePlus security ecosystem, this came as the second hit to the privacy of its users, the company witnessed a similar one last year in January wherein almost 40,000 were affected and users' credit card information was stolen. OnePlus's breach came after T-Mobile announced a similar data breach that impacted a small number of accounts using the company's prepaid offerings.

"Our Cybersecurity team discovered and shut down malicious unauthorized access to some information related to your T-Mobile prepaid wireless account," the company said. "None of your financial data (including credit card information) or social security numbers were involved, and no passwords were compromised."

"The data accessed was information associated with your prepaid service account, including name and billing address (if you provided one when you established your account), phone number, account number, rate plan and features, such as whether you added an international calling feature," the company further added.

DJI Proposed App to Identify Nearby Drones and Exact Location of Pilots


The world's leading producer of camera drones, DJI has demonstrated a technique to gather information about a nearby drone, precisely locating its pilot through a smartphone.

It employs a protocol called "Wi-Fi Aware", which makes the information about nearby drones available to anyone looking up for flying drones. The company said it would increase " safety, security, and peace of mind", along with preventing disruptions and security threats. However, the idea is being dismissed by security experts as they are of the opinion that it is not sufficient to fight illegal drone use and that the sophisticated hackers would easily manage to bypass the detection. With ransomware emerging as a service and being easily available, it's reasonable to expect hackers finding ways to circumvent the DJI's protocol. As a result, concerns have been raised regarding the viability of this "drone-to-phone remote identification" tool.

While substantiating the proposed idea, Brendan Schulman, VP of policy and legal affairs at DJI, said, "Remote ID functions as an electronic license plate for drones, allowing anyone who is curious about a drone in the sky to learn more about what it's doing."

"Around the world, aviation authorities have said remote ID is the key to allowing more complex drone use, and to solving concerns about safety and security." He added. "It's going to be very useful against rogue drones," said Elrike Franke, a policy fellow at the European Council on Foreign Relations, in a conversation with the BBC.

"But it's not going to be enough to fight people with real bad intentions, because these are going to be the first people to hack this system."

Further explaining the model, the company said, "Using a simple app, anyone within radio range of the drone can receive that signal and learn the location, altitude, speed, and direction of the drone, as well as an identification number for the drone and the location of the pilot."

However, the proposed app is not expected to be seen anytime soon due to the lack of Wi-Fi protocol compatibility with advanced smartphones. Currently, it also does not work on iPhones.

Cyber Intrusions on a Rise in Oregon, Attackers Bringing in Sophisticated Methods


Cyber intrusions have been on a rise with cybercrime becoming more dangerous and sophisticated than ever. The pervasive and evolving cybercrime poses a serious threat to both the public and private sector networks as attackers target international organizations to steal corporate data and individuals are subjected to identity theft.

In December 2018, Aaron Cole, from the Portland suburb of Oregon City, fell prey to a wire scam and nearly lost his home after being duped into making a fraudulent down payment of $123,000. The attacker sent Cole an email directing him to make the payment and tricked him into believing that it is from the title company he had been working with. At the time, Cole did not realize that a sophisticated network of hackers had been keeping track of his interactions with the title company. Although the email appeared similar in structure to the original emails he received from his title company, it had slight differences.

It was only when the title company reached out Cole on due dates, asking him to send the money, the realization of the blunder hit the Oregon man hard. He suddenly realized that he was duped by cybercriminals to give away all the money which he had saved from the sale of his former house along with other family savings.

Cole's title company, WFG came to his immediate rescue and made up for the losses, in turn, Cole is helping the company in spreading the word about more such scams. He was fortunate to be hired for the same amount he lost to the hackers - to be a spokesperson at the National Title Insurance Company.

“They warned we're never going to send you an email with wire instructions, it'll be an encrypted email. We’ll call you with wire instructions. They're putting all the red flags out there that they can possibly think of,” said Cole. “I was looking at it more like the terms of use when you want to download an app and you just skip through the thing and you click accept.”

While explaining the unfortunate incident and the state of mind which followed, the Oregon Husband and father of two said: "It was the worst feeling."

"And then having to go home and tell my wife that I just gave away all the money. She could tell right when I walked in the house and just sat down, and I just couldn't come up with the words to tell her." He added.

Referencing from the statements given by Gabriel Gundersen, an FBI supervisory special agent with the Oregon Cyber Task Force, "The emails have gotten well-crafted and quite detailed. They're highly tailored to that particular victim."

"It's a social engineering piece, where they're coercing a victim to do something based on an artificial agenda or an artificial timeline." He added.

Earlier the attempts made by attackers to dupe people were uncoordinated and clumsily executed due to which individuals had a scope of making distorted sense of anything which strikes them as strange and makes them feel uncomfortable, however now these cyber traps are set sophisticatedly making it difficult for individuals to locate the red flags.

Security officers are in a constant race with the attackers, ensuring they are not lacking behind with the fixes for every new approach slammed in by con men. However, the overall impact is still staggering as crucial systems are bypassed, disrupting the entire functioning of vital medical and banking networks.

xHelper: A Non-Destructive Malware that has Affected 45,000 Android Devices


A new Android trojan tension has become a headliner after darting upon the detector of several cyber-security firms and disturbing the smartphone users, because of its re-installing peculiarity that has become a headache. The malware was located in March for the first time but it gradually developed to affect the android phones.


Hot as xHelper, it is a unique malware that has been detected by antivirus corporations. xHelper is quite dangerous as it has a self re-install origin, a process that makes it very difficult to eliminate from Android gadgets. The Trojan is said to have corrupted around 45,000 devices. "Every day, 131 different devices are corrupted, whereas, 2,400 devices are being affected every month," says Symantec, a cybersecurity company. Eliminating the xHelper assistance from your Android device is useless as the malware re-establishes itself despite the user completing a factory reset.

In the conclusion of a story, the Trojan provides for popup ads on devices simultaneously beside spams. These popup notices make profits for the bodies responsible for the deed. Also, the trojan-infected android devices are required to install various apps from the Google Play Store, once the damage has been done. The malware secures profit in the scheme of pay-per-download payments, once the application is installed on the android phone.

But it appears that the Trojan does not perform any lethal actions on the device. "xHelper is only confined to interfering popup ads and spams, it doesn't possess any severe threat to the device" claims the reports of Symantec and Malwarebytes. Besides, excluding the xHelper assistance from the Android OS devices won't do any relief as the malware re-fixes itself despite the user restoring the phone to factory reset settings. The matter of concern, though, is the point that android device users have been notified that while xHelper is momentarily only confined to popups, spams, and ads, it can, however, install different applications, which could extend a secondary degree trojan threat that can steal sensitive data such as personal information and banking credentials of the users.

Pos Malaysia: Malware Attack Disrupts Internal Systems and Online Services



IT infrastructure of Pos Malaysia, postal delivery service in Malaysia, took a major hit from ransomware which rendered some of its online services inaccessible. After detecting the attack on Sunday, the company took immediate measures to shut down internal systems and parts of its online systems; they also lodged a police report with Royal Malaysia Police for attempted malware attack and reached out to concerned authorities to ensure the safety of their systems and database.

The website of the company was displaying an error message during the downtime, which said, “Sorry, we are under maintenance.” It was discovered during a system update on October 20 and since then, the company released three statements insisting on the safety of customers’ personal data and sensitive information. It assured that no user data was compromised and the issues are being rectified. Gradually, several of Pos Malaysia’s online services have been made accessible while over the counter services remain available at the company’s branches nationwide. However, the officials refrained from providing a specific timeline for the entire restoration of the halted services.

Seemingly, it was a major attempt that caused disruption in the company’s internal systems and online services for the past few days and subsequently affected the overall company’s operations.

In a statement on Facebook, Pos Malaysia told, “Our team has managed to rectify and restore several of the system and online services. We assure our customers that their data and personal information are safe.”

“We extend our apologies for the inconvenience caused and thank our customers for their kind understanding, patience and support during this period. We will provide regular updates from time to time,” it added.

Announcing that the services will be restored and made fully accessible gradually, a spokesperson told The Star, "Customers and business partners may now gradually access our services. Over the counter services at all branches remain available.”

"Currently, proactive steps are being taken by our IT recovery team to ensure minimal impact to our customers and business partners. While contingency plans are being considered to rectify and restore online operations, the majority of our services at all Pos Malaysia branches are still available," he added.

People who have made shipments via Pos Malaysia or have pending shipments and it required them to share any sensitive data with the postal delivery company, odds are it would have been compromised in the attempted malware attack, therefore, they are advised to check their private credentials where necessary.

Twitter Used Phone Numbers and Email Addresses Provided for Security to Target Ads


Twitter, on Tuesday, admitted using phone numbers and email addresses of users provided for the purpose of enhancing security via two-factor authentication to serve target ads.

However, sensitive user data has not been shared with the company’s third-party partners and the issue which stemmed the incident has been taken care of; now the phone numbers and email addresses are only asked for security purposes, according to Twitter.

Last year, Facebook was caught for engaging in a similar practice where the phone numbers and email addresses provided by the users to make their accounts more secure were used by the social media giant to target ads, as per the Federal Trade Commission (FTC).

In the wake of the breach, Twitter received widespread criticism for compromising its users' privacy. The fact that user security has been violated through a framework that was intended to rather strengthen it, further fuelled the public reproval. Although the company did not intend to use sensitive user data for the purpose of ad targeting, one can’t deny that the platform was practicing the aforementioned without the knowledge of its users. Moreover, it took the company almost a month to disclose the information.

Putting what Twitter called as an 'error' into perspective, it wrote in a post on its Help Center website, “Tailored Audiences is a version of an industry-standard product that allows advertisers to target ads to customers based on the advertiser's own marketing lists (e.g., email addresses or phone numbers they have compiled)."

"When an advertiser uploaded their marketing list, we may have matched people on Twitter to their list based on the email or phone number the Twitter account holder provided for safety and security purposes." The company added.

Remarking data (here) as a liability, Duruk, a human-computer interface expert, wrote “Phone numbers stored for 2FA end up in advertising hellhole. The more you accrue, the more someone inside your org will find a way to abuse it.”

Apologizing for the inadvertent mistake, Twitter further wrote, "We’re very sorry this happened and are taking steps to make sure we don’t make a mistake like this again."

Oyo Leaves Customers’ Confidential Data Unprotected Due to a Security Flaw



The world’s third-largest and fastest-growing hospitality and homestay chain, Oyo is reportedly leaving its customer data unprotected, which makes it vulnerable to a breach due to a flaw found in its security systems. A cybersecurity researcher, Jay Sharma, who used Oyo for the first time in his life, found a loophole in the service which was exposing confidential information of the customers availing the service.

Founded in 2013 by 25-year-old, Ritesh Agarwal, Oyo has confirmed the presence of security flaw in an email to the cybersecurity researcher who took to the professional networking site, LinkedIn to share his first time experience with the service and sent the report of the same to the company’s Cyber team on 22nd of August. The data at risk included booking IDs, contact numbers, the date of the booking, the number of people staying in the room and location.

Sharma was offered a bounty reward of Rs. 25,000, which is the increased amount after the officials, reviewed the severity involved, the initial amount offered was Rs. 5000.

Sharing the insights of the experience and the details of the vulnerability, Jay wrote on LinkedIn, “I used Oyo for the first time in my life, and once I checked in, it was compulsory to enter booking ID and phone number to access the Wi-Fi”, “Why should anybody in the room be forced to share personal information via OTP (one-time-password) verification to use Wi-Fi?”

“I researched more and found that the HTTP & Ssh ports were open with no rate limit for the IP which was hosting this. Captcha was a 5 digit number generated by math.random(). I created a way to brute force the login credentials while executing the captcha.”

“Once login was brute-forced all the historical data dating back to a few months was accessible. The booking IDs and phone numbers related to these IDs with timestamps were stored naked and all of it could be downloaded by parsing HTML using python scripts.” He wrote.

Jay further warned the customers not to log in and “wait till OYO announces officially that they have fixed this issue” as “all the properties which use this login are vulnerable.”

Commenting on the matter, the company, headquartered at Gurugram, said “Oyo provides safe and secure hotels to unmarried couples. Most Oyo hotels allow unmarried couples and accept local IDs; they have well-trained staff who ensure safety and privacy,”

“Any vulnerability, no matter how limited-time or small is taken very seriously and looked into,” a spokesperson told in a statement.

US: Fake News and Hike in Malicious Campaigns



'The internet is stacked with fake news sites in the present times,' says the research of Domain Tools, a security analyst company. The company scrutinized some top news sites of the U.S and examined their vulnerability to URL hacking and false domains. The false URLs may advertise misinformation and harmful malware, according to study. “As skepticism of traditional media continues to rise, defending the society from fake news attacks has grown relevant to the constitutional process,” says Corin Imai, a security advisor of DomainTools.

The fake news in recent times has attacked the credibility of news and raised questions concerning professional journalism. In present times, the media coverage is full of falsehoods and misinformation. The majority of the mainstream news sites can be held responsible for spreading fake news among the general public.

Why should one pay attention to fake news sites? 

'It’s no mystery that since recent times fake news campaigns are on a hike,' says Imai. 'The research shows that various top news websites' domain names have been tricked, and are vulnerable to URL hacking.' Honesty and assurance are the pillars of splendid consumer aid expertise. The study by Domain Tools reveals how wicked users do clever tricks like typosquatting and replicating domains as methods to wind up fake news campaigns.

Typosquatting, also called URL hijacking, is a technique that clings on internet users who accidentally type a wrong domain while searching for a news site on a browser. Whereas, spoofing is when a trickster acts as a genuine publisher of a news site. These unlawful actions can result in unauthorized stealing of user data, circulate fake news via spoofing news sites and, download dangerous malware into the user's system.

How to identify misinformation campaigns and stay safe from fake news sites- 

Fake news sites often benefit from user's browsing pace by hogging on their favored source of information. This can lead to data theft or vulnerability to fake news and malware.
Steps to avoid fake news-

• Beware of suspicious or doubtful domain names. Always pay attention to whether the web search is correct.
• Bookmark your preferred news site. This benefit in avoiding typos while searching for a news site.
• Visit the news website directly; avoid clicking on links that lead to news or information.
• Be digitally literate. Stay up to date with the latest trends and technologies happening over the internet.

By following these basic precautions, one can be safe from the risk of fake news.

Google Takes Down Around 46 Apps by Chinese Developers from its Play Store


Last week, around 46 apps by a Chinese developer, iHandy were taken down by Google from its Play Store. Initially, Google declined to provide reasons for the sudden removal of various security, horoscope, selfie, health and antivirus related apps which were downloaded over millions of times.

However, a total of eight apps were still present on Google’s Play Store, until three more were taken down, as per a Buzzfeed report. The Chinese company, established in the year 2008, claims to have almost 180 million monthly active users in more than 200 countries across the globe. Currently going through investigations, iHandy is one of the world’s largest mobile application developers.

In a conversation with Buzzfeed, iHandy VP Simon Zhu, while expressing how they found Google’s takedown quite unexpected, said “It is an unexpected action from our point of view. We are trying to find out the reasons. Hope the apps will be back to Play Store as soon as possible.”

Notably, Google has taken down apps made by Chinese developers in the past as well for various reasons; in this case, the removal is triggered by deceptive and disruptive ads. In August this year, after Trend Micro discovered malware inside certain apps, Google removed a total of 85 apps from its Play Store, most of these apps were related to gaming or photography and had more than 8 million downloads. The most popular names among these infected apps included, ‘Super Selfie’, ‘Cos Camera’, ‘One Stroke Line Puzzle’ and ‘Pop Camera’.

To exemplify, a very popular app known as ‘Sweet Camera- Selfie Beauty Camera, Filters’ which had over 50 million downloads was also removed in the process and it is not to be found on the Indian Play Store either.

Researchers discovered that all of these infected apps were put on the Play Store via distinct developer accounts and were signed by non-identical digital certificates, but they exhibited the same behaviors and shared a similar code.

Referenced from the statements given by Google’s spokesperson, "Our Google Play developer policies are designed to help create the best experience for users, and we explicitly prohibit deceptive or disruptive ads. When violations are found, we take action,"

Google about to Roll Out One of the Most Awaited Features



In 2018, Google broke headlines for tracking its users location even after they disabled the sharing of location history via their privacy settings.

There were complaints against the company, stating, "Google represented that a user ‘can turn off Location History at any time. With Location History off, the places you go are no longer stored.’ This simply was not true."

In the wake of receiving intense criticism over location history, Google came up with necessary adjustments which now allow users to stop the tech giant from tracking them, except for the applications in which location data is of utmost importance such as Waze and Google Maps.

In an attempt to make Google Maps even more secure and trustworthy, the company added enhanced security features related to location privacy in Android 10; to further better the services and regain the lost user trust, Google is planning to add Incognito Mode to Google Maps and the feature is said to be in testing.

Users can always put restrictions on the location data collected by Google Maps by signing out of their Google account, but it will come at the cost of their convenience, therefore, Google is planning to introduce Incognito Mode which can be turned on by the users in the same way they do it for Youtube or Google Chrome to delink the search or navigation data from their main Google account.

In order to activate Incognito Mode, users can simply choose the option from their Google account avatar and they will be informed about the app being in incognito mode by a black status bar and the marker indicating the location will turn into dark from blue to mark the change.

To enable the feature, users are recommended to install Preview Maps version 10.26 or higher and for those who are not a part of Preview Maps test group, wait until the company releases it on a wider scale.


Simjacker Exploits S@T Browser to Affect a Billion Users



Platform agnostic attack, Simjacker allows hackers to remotely exploit the victims' phone by sending a SMS which contains a malicious code; the code gives instructions to the universal integrated circuit card (UICC)/ SIM card placed inside the targeted device to retrieve and carry out sensitive commands.

The attack is set into motion as soon as the 'attack SMS' sent via another remote handset, is received by the targeted device. The process involves a series of SIM Toolkit (STK) directions particularly configured to be sent on to the SIM Card inside the victim's device.

To ensure a proper execution of these instructions, Simjacker exploits the S@T Browser, which is a software found in SIM cards. After receiving the 'attack SMS', SIM card resorts to the S@T Browser library for setting up the execution friendly environment which can trigger logic on the infected device.

S@T Browser, a legacy browser technology placed inside the SIM cards on a number of handsets, was typically used to send promotional messages or spam text messages. However, the attackers went on exploiting it for obtaining device's location and its unique International Mobile Equipment Identity (IMEI).

The attacker sends a SMS to the S@T browser asking it for the aforementioned information which it would obtain and store on to the SIM card. Then, the attacker would send another SMS to acquire the stored information. These messages are send and received in binary codes, unlike regular messages. It doesn't alert the victim in any manner and hence qualifies to be a highly effective tool for attacking mobile phones via messages.

Referencing from the findings of mobile carrier security company AdaptiveMobile Security, 

"The main Simjacker attack involves an SMS containing a specific type of spyware-like code being sent to a mobile phone, which then instructs the SIM Card within the phone to ‘take over’ the mobile phone to retrieve and perform sensitive commands." 

"We believe this vulnerability has been exploited for at least the last two years by a highly sophisticated attacker group." The report reads. 

Notably, the exploit is working as a lot of operators are failing to check the origin of these binary codes (SMS), which can be blocked by configuring the firewall technology in their corresponding networks, advises AdaptiveMobile.





Hackers Exploiting a Critical Weakness in Mobile Phones to Track Location



The interface designed for the usage of cell carriers is being exploited heavily by attackers. It allows the cell carriers to get in direct touch with the SIM cards inside subscribers' smartphones, the interface can be employed by the carriers for allowing subscribers to make use of the data stored on their SIM card to provide account balances along with other specialized services.

Hackers can secretly track the location of subscribers by exploiting the interface and giving commands to acquire the IMEI identification code of device; the Simjacker exploit further allows them to carry out actions such as making calls or sending messages.

According to the researchers at AdaptiveMobile Security, the working of the Simjacker exploit is not limited to a few devices, rather, it can be carried out on a wide range of mobile phones, irrespective of their software or hardware.

Unfolding the various aspects of the attack, Dan Guido, a mobile security expert and the CEO of security firm Trail of Bits told Ars, “This attack is platform-agnostic, affects nearly every phone, and there is little anyone except your cell carrier can do about it.”

While commenting on the issue, Karsten Nohl, the chief scientist at SRLabs, told Ars, “We could trigger the attack only on SIM cards with weak or non-existent signature algorithms, which happened to be many SIM cards at the time,”

 “AdaptiveMobile seems to have found a way in which the same attack works even if signatures are properly checked, which is a big step forward in attack research.” He added.

US: Investigators can Use Fake Social Media Profiles to Monitor Potential Visa Seekers





US Citizenship and Immigration Services officers, who were previously banned from creating fake social media profiles, can now create such profiles for the purpose of monitoring social media information of foreigners attempting for visas, citizenship and green cards.

On Friday, the ban was overturned in the review of potential privacy issues conducted and posted online by the Homeland  Security Department.

Explaining the need for the reversal of the ban, a statement by USCIS said that locating evidence of fraud and cross verifying the information for security reasons will be made easier for officers and investigators while deciding whom to allow inside the US.

The concerned State Department took several other steps which included asking applicants applying for US visa to provide their social media handles. However, it is ambiguous how resorting to fake social media identities would be carried out successfully as the terms and conditions of major social media platforms like Facebook and Twitter would clearly be violated while impersonating.

Commenting on the matter, Twitter said in a statement, "It is against our policies to use fake personae and to use Twitter data for persistent surveillance of individuals. We look forward to understanding USCIS's proposed practices to determine whether they are consistent with our terms of service,"

As per the DHS document, the investigating officers are restricted from interacting or conversing with people on various social media platforms and are only allowed to review and verify information passively. Although a lot of social media activity can be viewed and hence reviewed without an account,  certain platforms still keep within bounds the access for the guest users.

Referencing from the remarks made by Dave Maass, a senior investigative researcher for the civil liberties advocacy group Electronic Frontier Foundation, use of fictitious accounts "undermines our trust in social media companies and our ability to communicate and organize and stay in touch with people."

"It can't be this double standard where police can do it, but members of the general public can't." He added.

Older Lenovo users uninstall Solution Center soon

Owners of older Lenovo laptops need to uninstall the Lenovo Solution Center as soon as possible. 

Security researchers at Pen Test Partners found a critical vulnerability in the Lenovo Solution Center that could hand admin privileges over to hackers or malware.

According to Pen Test Partners, the flaw is a discretionary access control list (DACL) overwrite, which means a low-privileged user can sneak into a sensitive file by exploiting a high-privileged process. This is an example of a "privileged escalation" attack in which a bug can be used to gain access to resources that are normally only accessible to admins.

In this case, an attacker could write a pseudo-file (called a hard link file) that, when run by Lenovo Solution Center, would access sensitive files it otherwise shouldn't be allowed to reach. From there, damaging code could be executed on the system with administrator or system privileges, which is basically game over, as Pen Test Partners notes.

Lenovo Solution Center is a program that was preinstalled on Lenovo laptops from 2011 up until November 2018, which means millions of devices could be affected. Ironically, the program's purpose is to monitor the health and security of a Lenovo PC. While this flaw isn't such a big concern for individual users who can quickly protect their systems, larger companies who own a fleet of older ThinkPad laptops and use legacy software might be slow to react.

For its part, Lenovo published a security statement warning users about the bug and urging them to uninstall Solution Center, which the company no longer supports.

"A vulnerability reported in Lenovo Solution Center version 03.12.003, which is no longer supported, could allow log files to be written to non-standard locations, potentially leading to privilege escalation. Lenovo ended support for Lenovo Solution Center and recommended that customers migrate to Lenovo Vantage or Lenovo Diagnostics in April 2018," reads the statement.

New Vulnerability in Bluetooth Connections Allows Hackers to Spy on Private Conversations


Bluetooth is used worldwide as one of the most convenient methods of connecting and controlling the devices in range. However, according to a recent report, a vulnerability labeled as the KNOB (Key Negotiation of Bluetooth) attack has been found in Bluetooth connections.

All the Bluetooth compliant devices can be affected by the vulnerability, which allows attackers to spy on a victim's personal conversations. Hackers can also exploit the vulnerability to manipulate the data present on the compromised device.

How the attack unfolds? 

While establishing a functional Bluetooth connection, both the devices rely upon an encryption key. Therefore,
in order to execute the attack, hackers exploit the vulnerability in the Bluetooth standard and weaken this encryption of Bluetooth devices instead of breaking it straightaway.

The attacker gets in the way while the devices are setting up the encryption key and resorts to brute force attack for breaking the new key with less number of digits and manipulates both the devices to employ the new encryption key.

The vulnerability affects devices by some of the renowned manufacturers namely, Apple, Qualcomm, and Intel. Companies like Apple, Microsoft, Cisco, Google, Blackberry, Broadcom and Chicony has already issued a patch to fix the flaw, as per the reports by Mashable.

The group of researchers from the Singapore University of Technology and Design, University of Oxford, and CISPA Helmholtz Center for Information Security, who found this critical vulnerability, explained, "We found and exploited a severe vulnerability in the Bluetooth specification that allows an attacker to break the security mechanisms of Bluetooth for any standard-compliant device. As a result, an attacker is able to listen, or change the content of, nearby Bluetooth communication, even between devices that have previously been successfully paired."

RBI AnyDesk Warning; here's how Scammers Use it to Steal Money



In February, Reserve Bank of India (RBI) issued warning regarding a remote desktop app known as 'AnyDesk', which was employed by scammers to carry out unauthorized transactions from bank accounts of the customers via mobile or laptop.

In the wake of RBI's warning, various other banks such as HDFC Bank, ICICI Bank and Axis Bank along with a few others, also issued an advisory to make their customers aware about AnyDesk's fraudulent potential and how it can be used by the hackers to steal money via Unified Payments Interface (UPI).

However, it is important to notice that Anydesk app is not infectious, in fact, on the contrary, it is a screen-sharing platform of extreme value to the IT professionals which allows users to connect to various systems and mobiles remotely over the internet.

How the Scam Takes Places? 

When a customer needs some help from the customer care, he gets in touch via a call and if he gets on line with a scammer, he would ask him to download AnyDesk app or a similar app known as TeamViewer QuickSupport on his smartphone.

Then, he would ask for a remote desk code of 9-digit which he requires to view the customer's screen live on his computer. He can also record everything that is been shown on the screen. Subsequently, whenever the victim enters the ID and password of his UPI app, the scammer records it.

Users are advised not to download AnyDesk or any other remote desktop applications without fully understanding their functioning.

You should also be highly skeptical of the additional apps that customer support executives may ask you to download as besides fraudsters, no one asks for codes, passwords or any other sensitive information.

Student Uncovers Flaw in Education Software Exposing Data of Students



A high school senior in Lexington, Massachusetts discovered two vulnerabilities in software programs employed by his school which could have potentially affected the student data of around 5 million students.

Billi Demikarpi is a teen hacker who developed a penchant for hacking when he was in the freshman year and subsequently uncovered serious security flaws in two education programs, Aspen and Blackboard.

Reportedly, the probable consequences of these vulnerabilities would have been more disastrous than those San Diego Unified School District faced after the massive data breach that put to risk the data of more than 500,000 students along with the staff of the school.

The information that could have been exposed via the Aspen vulnerability includes details of bus routes, birthplaces, special education status, number of reduced or free lunches and suspensions.

It could have been exploited by the hacker to gain access to the data on the website after entering his own script as the Aspen website lacked the filters which other websites usually contain in order to reject hacker requests.

According to the statements given by both the companies, no one has exploited the security flaws besides Billi, who only accessed the information about himself and of a friend's whom he took consent from before doing so.

While sharing  his experience, Demirkapi said, “These companies say they're secure, that they do audits, but don't take the necessary steps to protect themselves from threats.”


Secure your Home Server from being used as a Hacking Server by Crooks


SSH also referred to as Secure Shell, is a cryptographic network protocol which secures remote login from one computer to another. It is employed by almost all the Linux sysadmins and although Windows users are more acquainted with Remote Desktop Protocol (RDP), many of Window sysadmins also use SSH instead of RDP, the reason being its Raw power.

RDP provides full graphical remote control of a Windows computer to its users along with access to the regular Windows desktop through keyboard and mouse, whereas SSH, which is comparatively more genric, allows user to run almost every program remotely which further lets him administer the system automatically from a distance through pre-written scripts or by entering commands live, it also allows user to do both simultaneously.

Resultantly, cybercriminals who somehow can get access to a user's SSH password can also access his system, if not the entire network.

Network tunneling is another feature provided by SSH, wherein, users build an encrypted network connection between multiple computers, they start from one computer to another and extends that connection to a third system to carry out the online work.

SSH server also acts as a special-purpose VPN or encrypting proxy when it allows users to redirect network traffic when they are on the go.

Therefore, criminals who have access to any user's SSH password can use his server as the basis for his future attacks and the victims would be blaming the owner of the server.

Now, unfortunately, people have an SSH server at their home even if they don't realize it as home routers have a pre-configured SSH server which is placed for administrative reasons.

While hacking, cybercriminals do not differentiate between the SSH servers manages by users themselves and those managed by their ISP's, they go on exploiting regardless, as these servers can potentially allow them to breach data and make a profit via reselling it.

Users are advised to take the time to understand and get familiar with their router's configuration settings, in the cases where it is not managed by ISP. Furthermore, turn off all the features you don't require and also the ones you are not certain about. Lastly, ensure that you are using the latest version.




Capital One Data Breach, Hacker gets Access to 100 Million Accounts


A massive data breach to Capital One servers compromised the personal details of an estimated 106 million bank customers and applicants across Canada and the US.

The suspected hacker, Paige Thompson, 33, has been arrested by FBI on Monday. She has shared details about the data breach on a GitHub page earlier in April, according to the criminal complaints.

Thompson broke into a Capital One server and illegally acquired access to customers' names, addresses, credit limit, contact numbers, balances, credit score, and other related data.

According to the documents, the 33-year-old, Seattle resident gained access to 80,000 bank account numbers, 1 million Canadian Social Insurance numbers, and 140,000 Social Security numbers.

Thompson who had previously worked with Amazon Web Services as a software engineer was able to access the data by exploiting a misconfigured web application firewall in company's infrastructure, as per a court filing.

Despite the magnitude of the breach, "no credit card account numbers or log-in credentials were compromised and over 99% of Social Security numbers were not compromised," the company told.

Expressing concern over the matter, Chairman Richard Fairbank, said, "While I am grateful that he perpetrator has been aught, I am deeply sorry for what has happened.

"I sincerely apologize for the understandable worry this incident must be causing those affected and I am committed to making it right," he assured.

Meanwhile, the company is notifying the victims and aiding them with identity protection and free credit monitoring.
