Hold Security Uncovers the Largest ever Security Breach!

COver one billion of stolen credentials to thousands of websites! According to Hold Security a Russian crime ring has amassed the largest known collection of stolen Internet credentials, including 1.2 billion user name and password combinations and more than 500 million email addresses.

After more than seven months of research, Hold Security identified a Russian cyber gang which is currently in possession of the largest cache of stolen data. While the gang did not have a name, Hold Security  dubbed it “CyberVor” (“vor” meaning “thief” in Russian).

The CyberVor gang amassed over 4.5 billion records, mostly consisting of stolen credentials. 1.2 billion of these credentials appear to be unique, belonging to over half a billion e-mail addresses. To get such an impressive number of credentials, the CyberVors robbed over 420,000 web and FTP sites.

How did this occur?  Initially, the gang acquired databases of stolen credentials from fellow hackers on the black market. These databases were used to attack e-mail providers, social media, and other websites to distribute spam to victims and install malicious redirections on legitimate systems. Earlier this year, the hackers altered their approach. Through the underground black market, the CyberVors got access to data from botnet networks (a large group of virus-infected computers controlled by one criminal system). These botnets used victims’ systems to identify SQL vulnerabilities on the sites they visited. The botnet conducted possibly the largest security audit ever. Over 400,000 sites were identified to be potentially vulnerable to SQL injection flaws alone. The CyberVors used these vulnerabilities to steal data from these sites’ databases. To the best of our knowledge, they mostly focused on stealing credentials, eventually ending up with the largest cache of stolen personal information, totaling over 1.2 billion unique sets of e-mails and passwords.

Who is affected? The CyberVors did not differentiate between small or large sites. They didn’t just target large companies; instead, they targeted every site that their victims visited. With hundreds of thousands sites affected, the list includes many leaders in virtually all industries across the world, as well as a multitude of small or even personal websites.
