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, security researchers say.
The records, discovered by Hold Security, a firm in Milwaukee, include confidential material gathered from 420,000 websites, including household names, and 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.
Hold Security would not name the victims, citing nondisclosure agreements and a reluctance to name companies whose sites remained vulnerable. At the request of The New York Times, a security expert not affiliated with Hold Security analyzed the database of stolen credentials and confirmed it was authentic. Another computer crime expert who had reviewed the data, but was not allowed to discuss it publicly, said some big companies were aware that their records were among the stolen information.
“Companies that rely on user names and passwords have to develop a sense of urgency about changing this,” said Avivah Litan, a security analyst at the research firm Gartner. “Until they do, criminals will just keep stockpiling people’s credentials.”
Websites inside Russia had been hacked, too, and Mr. Holden said he saw no connection between the hackers and the Russian government. He said he planned to alert law enforcement after making the research public, though the Russian government has not historically pursued accused hackers.
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.
