Data from about 1.2 billion Western web accounts became available to a group of Russian hackers called CyberVor. Confidential usernames and passwords were stolen from about 420, 000 websites of various large and small companies.
According to the news source, US digital security company Hold Security, the hackers did not sell the stolen data on the black market, but used the received contacts to send spam.
During the investigation by Hold Security, it was found out that the group of hackers is based in a small town in the south of the central part of Russia, not far from Kazakhstan and Mongolia. The team consists of a dozen men over the age of 20 who know each other personally.
According to the source, this precedent has become the largest data breach in the history of the Internet.
