Facebook and Google were the victims of an elaborate $100 million phishing attack, according to a Fortune report, with employees at both companies tricked into sending money to overseas bank accounts.

In March, the Justice Department arrested Evaldas Rimasauskas, the man they believe is at the center of the cyber crime, the publication reported. However, the names of the companies at the center of the scam weren't initially disclosed in the indictment. Meanwhile, the accused—who is being held in Lithuania pending extradition—has denied the allegations.
