A single click was all it took to launch one of the biggest data breaches ever.
One mistaken click. That's all it took for a Canadian hacker aligned with rogue Russian FSB spies to gain access to Yahoo's network and potentially the email messages and private information of as many as 1.5 Billion people.
The U.S. Federal Bureau of Investigation has been investigating the intrusion for two years, but it was only in late 2016 that the full scale of the hack became apparent. On Wednesday, the FBI indicted four people for the attack, two of whom are rogue FSB spies who work for the division that is supposed to cooperate with America’s FBI on cybercrime investigations. (The FSB is the succcessor to the KGB).
