On Monday, the FBI announced that they had found Peter Yuryevich Levashov —"one of the world's most notorious criminal spammers," according to prosecutors. The Russian cyber criminal had made the rookie mistake of using the same username and password for iTunes that he used for hacking, Wired reported.

Why it matters: The state-run Russian media company RT has reported that Levashov was involved in hacking during the U.S. election, although that has not been confirmed. At the very least, Levashov ran one of the world's biggest botnets and infected as many as 100,000 computers, including 10,000 in the U.S.
