Russian Web gang stole millions from Citi: report

WASHINGTON – The FBI is investigating a hacker attack on Citigroup Inc. that led to the theft of tens of millions of dollars, The Wall Street Journal reported Tuesday. The bank strenuously denied the report.

Citing anonymous government officials, the Journal reported that the hackers were connected to a Russian cyber gang. Two other computer systems, at least one of connected to a U.S. government agency, were also attacked.

In a statement, Citi said “any allegation that the FBI is working on a case at Citigroup involving a breach of Citi systems resulting in tens of millions of dollars of losses is false. There has been no breach and there have been no associated losses.”
