Pro-ISIS hackers targeting vulnerable WordPress websites, FBI warns

The Federal Bureau of Investigation (FBI) has issued a public service announcement concerning the continuous WordPress website attacks, which are being carried out by individuals sympathetic to the Islamic State in the Levant (ISIL) a.k.a. Islamic State of Iraq and al-Shams (ISIS) through a vulnerability in the WordPress content management system.

According to the researchers, an attacker could install malicious software; manipulate data; or create new accounts with full user privileges by  exploiting the vulnerabilities resulting in an attacker gaining unauthorized access, injecting scripts, bypassing security restrictions, and stealing cookies from computer systems or network servers.

The attackers didn’t targeted Web sites by name or business type. They used common WordPress plug-in vulnerabilities, which can be easily exploited by common hacking tools.

These are the following steps recommended by FBI, if your web
site has been targeted.

1)Review and follow WordPress guidelines:

 http://cve.mitre.org/index.html
  https://www.us-cert.gov/

3)Update WordPress by patching vulnerable plugins:

4)Run all software as a non-privileged user, without administrative privileges, to diminish the effects of a successful attack

5)Confirm that the operating system and all applications are running the most updated versions

Personal data exposed as Linux Australia server hacked


Linux Australia, an organization of open-source and free software user group, revealed that one of their server was hacked. The personal details of conference attendees might have been accessed.

According to the organization only the personal data including the names, street, phone numbers and email addresses of delegates for Linux Australia conferences and PyCon have been exposed in a server breach. No financial data have been exposed because they use a third party payment system.

A server had been attacked on March 22, but the Linux Australia discovered the breach on March 24,after conference management software Zookeepr started sending a large number of error reporting emails.

The hackers utilized an unknown vulnerability to trigger a remote buffer overflow and obtain full control of the server hosting the information by installing  a remote access tool and then botnet command and control software.

Joshua Hesketh, Linux Australia’s president wrote “It is the assessment of Linux Australia that the individual utilised a currently unknown vulnerability to trigger a remote buffer overflow and gain root level access to the server. A remote access tool was installed, and the server was rebooted to load this software into memory. A botnet command and control was subsequently installed and started. During the period the individual had access to the Zookeepr server, a number of Linux Australia’s automated backup processes ran, which included the dumping of conference databases to disk.”

Immediately  responding to the incident, Linux Australia has decommissioned the infected server, and announced improvements to its architecture and security.

Hackers target Executive club members of British Airways

Being an executive customer at British Airways (BA) does not guarantee any better security from hackers. Thousands of executive customers found this out to their peril as BA confirmed the hacking of the accounts.

According to the company, it was not a direct attack on the central database; the attack was carried out on some account holders using information on the users available elsewhere on the internet. Also, the company maintained that only “a small number of frequent flyer Executive Club accounts” had been affected and though there has been some unauthorized activity, no sensitive information had been leaked.

Though the company said that the hackers had not gained any access to any subsequent information pages like travel histories or payment card details within accounts, BA Executive Club (BAEC) account holder have registered complaints on the forums saying that their Avios points have been stolen. Avios points are accumulated through frequent travel can be used for other flights or upgrades. Tier points have not been affected due to this hack.

One user wrote, “My Avios balance, which was 46,418 yesterday, is suddenly zero,” Another said, “217,000 taken from my account this morning. 30 minute hold on the silver line.”
Other people are also reporting they are unable to access their accounts at all, with their BAEC number not being recognized at all.The company responded saying that the accounts have been locked down from access as a response to the breach and all the points would be subsequently reinstated.

Some members of BAEC affected by the issue have received emails requesting change of passwords, for those who have not but still are locked out of the accounts can place a call to the customer care.

For customers wanting to book flights now, bookings as redemption of points might not be available pending resolution of the matter but still can be checked for availability.

Alternatively, one might, if the options are available try to book through Avios.com which has not been affected.

However, with so many cases, it is best to wait for a few days till the situation becomes clearer.

Banking Trojan Vawtrak

Banking Trojan Vawtrak (aka Neverquest or Snifula) which additionally uses the Pony module to steal wide range of log-in credentials has been proliferating rapidly over the last few months

 USA, Germany, UK, Czech Republic are the  top  affected countries this year.

While Trojans like this are not new, what makes it remarkable is the  the multi-layered concealing processes and wide range of functions it can execute.

The Vawtrak Trojkan spreads via drive-by download – in the form of spam email attachments or links to compromised sites or  through malware downloaders such as Zemot or Chaintor or through exploit kits like Angler.

Tracking the Trojan  Vawtrak, AVG has revealed a detailed analysis of its installation and functionality.

Installation
The trojan was delivered through a spam email from Amazon which contained link to a zip archive stored on a compromised Wordpress site. The delivered file which actually was a executable tried to simultaneously look as  a pdf and a screen saver. It then installed itself into the system and ensured persistence by enabling auto-execution  Windows start-up. Without causing visible changes in the system, it then dropped the DLL into the program folder and deleted its original version.

This shorter second DLL decrypts its payload, which looks like  a normal Windows exe file but is a compressed file. The decompressed file replaces the second DLL and extracts the final module in a compressed format which further contains another two DLL files. The appropriate DLL then executes Vawtrak's main functionality.

Functionality
Once executed, Vawtrak disables antivirus protection of almost all known anti-viruses, steals multiple passwords from browsers (even obscure browsers such as K-Meleon or Flock) or applications, steals browser history, modifies browser settings, logs keystrokes, takes screenshots or records user actions on desktop, enables remote access to victim's system.

Further it communicates with remote Control & Command servers, executing commands from a remote server, sending stolen information, downloading new versions of itself and web-injection frameworks.
One fascinating feature is that it can connect to the update servers  hosted on the Tor hidden Web services via a Tor2web proxy without installing any special software such as Tor browser. Moreover, the communication with the remote server is done over SSL, which adds further encryption. Due to the use of steganography, the user remains totally ignorant of the working and updation of the Trojan.

Vawtrak is not as advanced as some others but its actions are too aggressive and they may cause stability or performance issues in the infected machines.

Staying vigilant about online phishing and scams is the most efficient way of avoiding Vawtrak but as it may still find its way, even without a user's direct interaction. So having an efficient and updated antivirus solution is of utmost importance.

UK based gaming company Multiplay reports unauthorised access of servers, sounds warning bell

Multiplay, a gaming event company recently bought by GAME has alerted its users of a potential breach of its network.

The alert was sounded by Multiplay, by sending an email to its users, encouraging them to change their passwords due to an unauthorized access detected by the company on its systems. Multiplay has assured users that no payment information has been leaked as such information is not stored on its servers.

The email was confirmed by Multiplay on its twitter handle also and asked users to follow the instructions in the email.

Speculations are going around that the breach of the company's servers is the work of some gamers not happy with the recent acquisition of Multiplay, by retailer GAME.

The step has been seen as action to undermine this years gaming festival, Insomnia, hosted by Multiplay.

Data Breach at Sacred Heart Health Systems


A security breach at one of the third-party vendors of Sacred Heart Health Systems has resulted in the exposure of health and personal information of approximately 14,000 patients.

Hackers were able to access patients’ names, dates of service, dates of birth, diagnoses and procedures, total charges, and physicians’ names, and 40 of the patients Social Security numbers were also compromised, through phishing attack by gaining access to the email account of an employee of the billing vendor.

The incident was first discovered on Dec. 3, 2014, and username and password of the employee was immediately shut down. On Feb 2,2015, Sacred Heart was notified of the attack.

 They immediately launched an internal investigation by engaging computer forensics experts, to conduct and analyze the incident and help to accurately identify affected ones, and they sent letters to all affected patients informing them about the hacking attack. The hacker has not been identified.

Data breach of Advantage Dental


An intruder had accessed internal membership information of more than 151,000 patients of an Advantage Dental, a Redmond-based provider that serves low-income patients at more than 30 clinics in Oregon, in late February, announced on Monday.

According to the Advantage Dental, there is unauthorized access to patients’ names, social security numbers, home addresses, phone numbers, and dates of birth, but treatment details, payment or other financial data were not accessed.

A malware obtained a username and password of Advantage employee’s computer that allows access to the membership database, which is separate from the database that contains financial and treatment information.

An intruder accessed the information continuously for three days from 23 Feb to 26 Feb. Internal IT specialists of Advantage Dental terminated the illegal access immediately upon discovery. Computers equipped with anti-virus software fails to detect new variations of a virus.

No patients have complained about the data being used for criminal activity. Advantage has made necessary security changes in all its clinics, and headquarters in Redmond to avoid further data breach.

Limited portion of ASML's IT System hacked


An unnamed hacker broke into a limited portion of an  IT system of a semiconductor supplier company called ASML on Sunday. In their initial investigation, ASML revealed that only a limited amount of data has been accessed.

According to  ASML, there has not been any evidence of  valuable files, both  from their or customers and suppliers side, has been compromised. Their IT staff quickly got to know about the break-in the IT system and took immediate step.

ASML is a multinational Dutch company, with its presence  felt in more than 16 countries in over 70 different locations. They make photolithography machines for the production of integrated circuits such as CPUs and memory chips, that improve the quality of life.

In recent times, many large companies have been targeted by hackers, but they  are constantly working to improve their defenses against hacking attempts and their detection capabilities.

ASML is listed in Euronext Amsterdam and NASDAQ under the symbol ASML.

Three suspects arrested in china for spreading WireLurker malware


Now a days, any mention of malware and Macs in the same setting generally conjures up images of WireLurker. It was notable as a new family of malware specifically targeting iOS devices via USB and is able to penetrate the iPhone's strict software controls.

WireLurker has been in action in China for the past six months, first infecting Macs by inserting Trojan software through repackaged OS X apps, then moving on to iOS devices. The firm claims that it is the first to automate generation of malicious iOS apps by implementing a binary file replacement attack.

Security experts at Palo Alto Networks traced WireLurker in a research paper saying "It is the biggest in scale we have ever seen! “. WireLurker can jump from a Mac onto an iPhone running a vanilla version of Apple's operating system by leveraging Apple's enterprise provisioning assets.

The WireLurker attackers "probably aren't people who do this often," says Ryan Olson, intelligence director of Palo Alto Networks' Unit 42. They are "clearly very skilled MacOS or iOS developers," but they definitely are not very experienced in writing malware.

With Apple's global smart phone market share continues to rise, so do the number of attempts to surreptitiously harvest data from unsuspecting consumers. As for who created WireLurker, Palo Alto's best guess is that this is one individual or a small group of individuals operating within China, independently of any nation-state. They could be a startup malware house in the new financially motivated, politically independent cybercrime underground growing behind the Great Wall.

Taking advantage of an app provisioning vulnerability, WireLurker lays dormant on a user's computer in an infected OS X app. The malware monitors for new iOS devices and installs malicious apps downloaded from an off-site server or generated autonomously on-device. From there, the program can access user information like contacts, read iMessages and perform other functions determined by the command-and-control server.

So far, 467 OS X apps have been infected and distributed through China's third-party Maiyadi App Store, with downloads totaling over 356,104 possibly impacting "hundreds of thousands of users."

While many publications have dubbed WireLurker “a new brand of threat,” it seems that the majority of users have nothing to worry about. It’s relies on a USB connection for delivery—a practice that has gone by the wayside for most folks in recent years.

On November 14, the Beijing Municipal Public Security Bureau announced it had arrested three people in connection with the WireLurker malware which brought a sense of relief among Apple users of China.

The police received a tip from the Chinese technology company Qihoo 360 and subsequently arrested three individuals, respectively surnamed Chen, Li, and Wang.

The third-party app store that had been serving WireLurker, Maiyadi, was also shut down. Apple has already taken steps to block infected programs but the rest of the work rests on users.

Cape May-Lewes Ferry Confirms Credit Card Data Breach


The Cape May – Lewes Ferry has confirmed its payment data systems were infiltrated by hackers who took payment card data on certain systems at the Cape May-Lewes Ferry’s terminals and vessels.

Delaware River and Bay Authority(DRBA) that operates the Cape May – Lewes Ferry learned of a possible data breach on July 30 - The same day Jimmy John's learned of the data breach.

The organization with the help of third-party cyber forensic experts has determined that its card processing systems relating to food, beverage , and retail sales only were compromised.

Credit and Debit card data of individuals who have made purchases from September 20, 2013 through August 7, 2014 at the Cape May – Lewes Ferry ’s terminals and vessels at risk.

The malware planted by the cyber criminals has been eliminated.  The card data accessed by the malware includes card numbers, cardholder's names and/or card expiration dates.

DRBA is offering free identity protection services, including credit monitoring to affected customers.

PHP has fixed several vulnerabilities allowing remote code execution


The PHP development team has released new versions in order to fix three security vulnerabilities -one of them is said to be a critical one and leads to remote code execution.

The vulnerability identified as "CVE-2014-3669" can cause an integer overflow when parsing specially crafted serialized data with the unserialize ().The vulnerability is only a 32-bit system, but the danger is caused by the breach and that the serialized data often come from user-controlled channels.

In addition, the updates have been corrected errors associated with the introduction of a null byte in the library cURL, calling the damage dynamic memory during processing of the modified data as a function of exif_thumbnail () in image processing (CVE-2014-3670), as well as buffer overflow in the function mkgmtime () from the module XMLRPC (CVE-2014-3668).

These vulnerabilities were discovered by the Research lab of IT security company High-Tech Bridge.

The new versions 5.6.2,5.5.18 and 5.4.34 address these three vulnerabilities.

Russian Hackers use Windows 0-Day exploit to hack NATO, Ukraine

Russian Hackers, dubbed the "sandworm team", have been found exploiting a previously unknown vulnerability in Microsoft's Windows Operating systems, reports iSight.

The group has used this zero-day exploit to hack computers used by NATO, Ukraine Government, European Telecommunications firms, Energy sectors and US academic organization.

The attack starts with a spear-phishing email containing a malicious power point document that exploits the vulnerability and infects victims machine with a malware.

"The vulnerability exists because Windows allows the OLE packager (packager .dll) to download and execute INF files."the report reads.

".. When handling Microsoft PowerPoint files, the packagers allows a Package OLE object to reference arbitrary external files, such as INF files, from untrusted sources... This will cause the referenced files to be downloaded in the case of INF files, to be executed with specific commands"

The vulnerability is reportedly affecting all versions of the windows operating systems from Vista SP1 to Windows 8.1.  It also affects Windows servers 2008 and 2012.

A Bug in Bug Tracker "Bugzilla" exposes Private Bugs


A critical vulnerability in the popular web-based Bug tracking tool "Bugzilla" allows hackers to view the details of any undisclosed vulnerabilities.

Bugzilla is an open source bug tracking program developed by Mozilla and being used by many large organizations including RedHat, Linux Kernel, Gnome, Apache.

Vulnerability researchers at Check Point Software Technologies reported the bug to Mozilla that allows anyone to register with email address of the targeted domain (for example, admin@mozilla.com) and bypass email validation.

Researcher exploited the vulnerability and managed to create administrator accounts for the Mozilla.org, Mozilla.com and Bugzilla.org.

Gervase Markham from Mozilla wrote a detailed technical post.  The attack method appears to be "HTTP Parameter Pollution(HPP)" technique.

OWASP Definition for HPP:
"Supplying multiple HTTP parameters with the same name may cause an application to interpret values in unanticipated ways. By exploiting these effects, an attacker may be able to bypass input validation, trigger application errors or modify internal variables values."
Patch:
Mozilla has released a security update that not only patches this privilege escalation vulnerability but also few other bugs including Cross Site scripting and Information Leak.

Everything you need to know about Bash Bug "ShellShock"


A new critical security vulnerability in the BASH shell, the command-line shell used in many Unix and Linux operating systems, leaves a large number of systems at security risk. The bug also affects Mac OS X.

CVE Number: CVE-2014-6271

Technical Details: 

Here is technical details of the vulnerability, posted by Florian Weimer in Seclists:

"Bash supports exporting not just shell variables, but also shell functions to other bash instances, via the process environment to (indirect) child processes.  Current bash versions use an environment variable named by the function name, and a function definition starting with “() {” in the variable value to propagate function definitions through the environment.

The vulnerability occurs because bash does not stop after processing the function definition; it continues to parse and execute shell commands following the function definition.  For example, an environment variable setting of

  VAR=() { ignored; }; /bin/id

will execute /bin/id when the environment is imported into the bash process. (The process is in a slightly undefined state at this point. The PATH variable may not have been set up yet, and bash could crash after executing /bin/id, but the damage has already happened at this point.) "

Proof of Concept:
env e='() { Ignored; }; echo Vulnerable' bash -c "echo Hello"

Running the above command in Linux Terminal prints "vulnerable" and "Hello".So what exactly is happening here.

The 'env' command used to either print a list of environment variables or run another utility in an altered environment without having to modify the currently existing environment.

Here, the utility is 'bash' that executes the 'echo hello' command - and the environment variable 'e' is imported into the 'bash' process.

The bash shell process the function definition "() { Ignored; };"and then executes the "echo vulnerable" command.

* You can use the above POC code to test whether your system is vulnerable or not.

Real world Attack Scenario:

CGI stores the HTTP headers in environment variables. Let's say the example.com is running a CGI application written in Bash script.

We can modify the HTTP headers such that it will exploit the shellshock vulnerability in the target server and executes our code.

POC:

curl -k http://example.com/cgi-bin/test -H "User-Agent: () { :;}; echo Hacked > /tmp/Hacked.txt"
Here, the curl is sending request to the target website with the User-Agent containing the exploit code.  This code will create a file "Hacked.txt" in the "/tmp" directory of the server.

Who should be worried?
An attacker needs to send a malicious environment variable to an application that interacting with the Internet and this application should have either written in Bash or execute bash script within the app. So, Normal Desktop users are likely not affected by this bug.

However, if you are admin of a website and running CGI app written in BASH or using Bash script, You should be worried.

Metasploit Module:

A Metasploit Module has been released that exploits a code injection in specially crafted environment variables in Bash, specifically targeting Apache mod_cgi scripts through the HTTP_USER_AGENT variable.

You can find the module here.

Malware:
Cyber Criminals are already started to exploit this vulnerability for the malicious purpose.  A malware(ELF format) named as 'Linux/Bash0day', found by @yinettesys.

"Cybercriminals exploit bash 0day to get the ELF malware into web servers. ELF scans routers IP and sends exploit busybox to hack routers and doing DDoS." Malware Must Die who analyzed the malware told EHN.

"If exploit busybox hits the target, they will try to gain shell /bin/sh & brute the default login/passwords commonly used by routers"


Strings contained in the Malware sample

At the time of writing, the detection ratio in Virustotal is 0/55.

You can find the malware sample and more details of the malware at KernelMode website.

Wormable:
Robert Graham of Errata Security says the bug is wormable.  He wrote a script that scans the Internet and finds the vulnerable machines. So far, he found nearly 3,000 vulnerable systems on port 80.

"Consequently, even though my light scan found only 3000 results, this thing is clearly wormable, and can easily worm past firewalls and infect lots of systems." Graham wrote in his blog post.

Patch:
A Patch has been released which ensures that no code is allowed after the end of a Bash function.  If you try to run the exploit code after applying the patch, you will get the following error message:



Unfortunately, the patch is incomplete, it still can be bypassed.  There is a workaround here, but it is not advisable. "CVE-2014-7169" has been assigned for the incomplete fix.

If you think we missed any information, feel free to comment here, we will add it to the article.

---------------------------------

Additional details:
This details isn't for you if you already know how export functions,'env' commands work :

Bash Export function-definition feature: 



Defining a function in Bash script:

       hello(){ echo "Hello World";}

Calling function in Bash script:
   hello

Create a child bash process and call our user-defined function:
bash -c hello

It won't work, because the child bash process doesn't aware that there is user-defined function called "hello". So, what to do?! Let us add the 'hello' function to the environment variable with Export command:

export -f hello

This will export the 'hello' function to the child process.  Let's try to create the child bash process again:

bash -c hello

Now the function is called without a problem.


We can achieve the samething in a single line with 'env' command. Let me first explain what 'env' command does.



'env':


The 'env' command used to either print a list of environment variables or run another utility in an altered environment without having to modify the currently existing environment.

Let's try to print environment variables with bash(creating child process):

bash -c printenv



The above command will print environment variables. Using 'env' command, you can pass a temporary environment variables to the child process:

env e="hello" bash -c printenv


Now, If you check the printed environment variables, you can find the "e='hello" in the result :)

Function passing with env command:

env hello='() { echo Hello World;};' bash -c hello

Jimmy Johns hit by Point of Sale(POS) Malware

Jimmy John's is the latest company hit with Point-Of-Sale(POS) information breach. 

The Illinois based sandwich shop said it learned of the hack on July 30 and immediately hired security experts to help with the investigation.

In July, Brian Krebs reported that multiple financial institutions were seeing fraud on cards that had all recently been used at Jimmy John's locations.  He also reported that the stores are using pos systems made by a third party vendor Signature Systems Inc.  At the time,  the breach was not confirmed.  After nearly two months, the company confirmed it.

According to the company's statement, hackers stole log-in credentials from its POS vendor and used them to gain access to Jimmy John's POS systems.

The Signature Systems also confirmed the breach that attackers gained access to user name and password that they used to remotely access the POS systems.

The attackers then installed a malware which is designed to capture payment card data from cards that were swiped through terminals.

The information including card number, verification code, expiration date and card holder's name are at risk. The company says the information entered online such as email ids,passwords are not affected.

The incident affected approximately 216 Jimmy John's stores.

Data Breach at TripAdvisor's Viator affects 1.4 million customers, card information stolen

The travel site Viator, a subsidiary of TripAdvisor, has suffered a data breach that has compromised customer's information which includes payment card information.

The company is in the process of notifying nearly 1.4 million customers about the breach.  Of that number, approximately 880,000 people had their payment card data compromised(credit/debit card number, expiration date, name, billing address, email address).

A further 560,000 customers had their account information including email IDs, hashed passwords and nickname accessed by the attackers.

The company said that at this time they have no reason to believe customer's card security codes had been compromised.  They company also said that they don't collect debit PIN numbers, so it could not be compromised.

Viator became aware of the breach after receiving a notification from its payment card service provider that unauthorized charges occurred on a number of our customers' credit cards.

The company said it hired forensic experts to investigate the incident and to identify how their systems may have been impacted.

It is also offering a free identity protection services and credit card monitoring services for those affected individuals.



jQuery.com reportedly hacked to serve malware


JQuery.com, the official website of the popular javascript library JQuery(used by nearly 70% of top 10,000 websites), had reportedly been compromised and had served credential stealing malware. 

RiskIQ announced that they had detected a malicious script in jquery.com that redirects visitors to a website hosting the RIG Exploit kit.

The redirector domain(jquery-cdn[dot]com) used in this attack has been registered on September 18, the same day on which the attack was detected by RiskIQ.  RiskIQ believes that this domain was intended specifically to blend into the website.

The good news is that RiskIQ found no indication suggesting that the JQuery library itself has been affected.  Otherwise, many additional websites using the JQuery CDN to load the JQuery library would also have been affected.

The people at JQuery.com says they found no logs or evidence that their server was compromised.

"So far the investigation has been unable to reproduce or confirm that our servers were compromised. We have not been notified by any other security firm or users of jquery.com confirming a compromise." JQuery.com blog post reads.

Vulnerability in Android default browser allows attackers to hijack Sessions


A Serious vulnerability has been discovered in the Android default browser(AOSP) that allows a malicious website to bypass "Same Origin Policy(SOP)" and steal user's data from other websites opened in other tabs. AOSP browser is the default browser in Android versions older than 4.4. 

What is Same Origin Policy?
SOP plays an important role in the Web Security, restricts a website from accessing scripts and data stored by other websites.  For example, the policy restricts a site 'Y' from accessing the cookies stored by site 'X' in user's browser.

Same Origin Policy Bypass:
Rafay Baloch, a security researcher, found a security flaw in the "Same Origin Policy" system used by the AOSP browser.  The bug allows the website 'Y' to access the scripts and user's data stored by website 'Y'.

Imagine You are visiting attacker's website while your webmail is opened in another tab, the attacker is now able to steal your email data or he can steal your cookies and could use it to compromise your mail account.

Proof of Concept:
<iframe name="test" src="http://www.example.com"></iframe>
<input type=button value="test"
onclick="window.open('\u0000javascript:alert(document.domain)','test')" >


"Its because when the parser encounters the null bytes, it thinks that the string has been terminated, however it hasn't been, which in my opinion leads the rest of the statement being executed." Rafay said in his blog.

Metasploit Module:
Rafay published the poc on his blog in August.  However, it remained largely unnoticed until rapid7 released a metasploit module that exploits the vulnerability.
http://www.rapid7.com/db/modules/auxiliary/gather/android_stock_browser_uxss

This browser also known for the remote code execution vulnerability, has been discontinued by Google. But older versions of Android do come with this browser.

What you should do?
Stop using the default android browser, Use Google Chrome or Mozilla.

About 5 million Gmail IDs and passwords leaked

Around 5 million Gmail user names and related passwords have been leaked in Russian Bitcoin security forum.

Is Google got hacked?
No, the leak was not the result of a security breach of Google systems.  The dump is said to have been obtained from other websites.

So, if you have used the same password used anywhere else, your gmail account could be compromised.

Google's response
"We found that less than 2% of the username and password combinations might have worked, and our automated anti-hijacking systems would have blocked many of those login attempts. We’ve protected the affected accounts and have required those users to reset their passwords." Google wrote.

What You should do?
  • There are few websites available online to check whether your gmail ID have been compromised or not.  My suggestion is don't use them.  I suggest everyone to change the password.(I believe most of the people keep the same password for years, so it's better to change now).
  • If you have not enabled 2-step-factor feature, it is good to enable it.
  • Never use the gmail password in any other websites.
