According to the publication, iSight announced that it has detected a number of clues that suggest that the hackers would work for the Russian government. At least one of the hackers is fluent in Russia, considering unprotected documents stored on a server used by attackers. Another clue, according to the company, is the time and significant amounts of money needed to find errors in complex software like Windows, which suggests that hackers could benefit from the resources of a government, which is behind them. Governments may use intelligence agencies to locate or acquire such breaches findings from elite hackers.

The company also announced that it has detected this group of online hackers since the end of 2013.
