FBI Says Russian Hackers Hit Citigroup for Tens of Millions

The FBI is looking into what the government says was a cyberattack on Citigroup (C), probably from inside Russia. The Wall Street Journalreports that the action "resulted in a theft of tens of millions of dollars by computer hackers." Citi claims that the report is not true. "We had no breach of the system and there were no losses, no customer losses, no bank losses," said Joe Petro, managing director of Citigroup's security and investigative services.
