A Russian crime ring has amassed the largest known collection of stolen internet credentials, including 1.2 billion username and password combinations and more than 500 million email addresses, security researchers say.
The records, discovered by Hold Security, a firm in Milwaukee, include confidential material gathered from 420,000 websites, ranging from household names to small internet sites. Hold Security has a history of uncovering significant hacks, including the theft last year of tens of millions of records from Adobe Systems.
“Hackers did not just target US companies, they targeted any website they could get, ranging from Fortune 500 companies to very small websites,” said Alex Holden, the founder and chief information security officer of Hold Security. “And most of these sites are still vulnerable.”
There is worry among some in the security community that keeping personal information out of the hands of thieves is increasingly a losing battle. In December, 40 million credit card numbers and 70 million addresses, phone numbers and additional pieces of personal information were stolen from the retail giant Target by hackers in Eastern Europe.
And in October, federal prosecutors said an identity theft service in Vietnam managed to obtain as many as 200 million personal records, including Social Security numbers, credit card data and bank account information from Court Ventures, a company now owned by the data brokerage firm Experian.
But the discovery by Hold Security dwarfs those incidents, and the size of the latest discovery has prompted security experts to call for improved identity protection on the web.
“Companies that rely on usernames and passwords have to develop a sense of urgency about changing this,” said Avivah Litan, a security analyst at Gartner, the research firm. “Until they do, criminals will just keep stockpiling people’s credentials.”
So far, the criminals have not sold many of the records online. Instead, they appear to be using the stolen information to send spam on social networks like Twitter at the behest of other groups, collecting fees for their work.
But selling more of the records on the black market would be lucrative.
The hacking ring is based in a small city in south central Russia, the region flanked by Kazakhstan and Mongolia. The group includes fewer than a dozen men in their 20s who know one another personally – not just virtually. Their computer servers are believed to be in Russia.
“There is a division of labor within the gang,” Holden said. “Some are writing the programming, some are stealing the data. It’s like you would imagine a small company; everyone is trying to make a living.”
