The US Federal Reserve bank has confirmed one of its internal websites was broken into by hackers after the hacktivist group Anonymous was claimed to have stolen details of more than 4,000 bank executives.
"The Federal Reserve system is aware that information was obtained by exploiting a temporary vulnerability in a website vendor product," a spokeswoman for the US central bank said.
"Exposure was fixed shortly after discovery and is no longer an issue. This incident did not affect critical operations of the Federal Reserve system," the spokeswoman said, adding that all individuals affected by the breach had been contacted.
The admission follows a claim that hackers linked to Anonymous struck the bank on Sunday. The technology news site ZDNet separately reported that Anonymous appeared to have published information said to containing the login information, credentials, internet protocol addresses and contact information of more than 4,000 US bankers.
