FBI Probes Hack at Citibank

Siobhan Gorman and Evan Perez write on The Wall Street Journal:

The Federal Bureau of Investigation is probing a computer-security breach targeting Citigroup Inc. that resulted in a theft of tens of millions of dollars by computer hackers who appear linked to a Russian cyber gang, according to government officials.

The attack took aim at Citigroup's Citibank subsidiary, which includes its North American retail bank and other businesses. It couldn't be learned whether the thieves gained access to Citibank's systems directly or through third parties.

The attack underscores the blurring of lines between criminal and national-security threats in cyber space. Hackers also assaulted two other entities, at least one of them a U.S. government agency, said people familiar with the attack on Citibank.

The Citibank attack was detected over the summer, but investigators are looking into the possibility the attack may have occurred months or even a year earlier. The FBI and the National Security Agency, along with the Department of Homeland Security and Citigroup, swapped information to counter the attack, according to a person familiar with the case. Press offices of the federal agencies declined to comment.
