The US Federal Bureau of Investigation (FBI) is looking into how a conference call with Scotland Yard was intercepted by a member of the activist hacking group Anonymous.
A recording of the call that covered updates to ongoing court cases involving hackers, and the intercepted FBI e-mail that told the Anonymous hacker when it was going to take place and provided dial-in details, have been published online.
The FBI e-mail referred to an investigation into a number of hacking groups. It read: “A conference call is planned for next Tuesday (17 January 2012) to discuss the ongoing investigations related to Anonymous, LulzSec, Antisec, and other associated splinter groups,” according to The Telegraph.
"The information was intended for law enforcement officers only and was illegally obtained. A criminal investigation is underway to identify and hold accountable those responsible,” the FBI said in a statement.
London Metropolitan Police's central e-crime unit said the matter was under investigation, but that no operational risks had been identified, according to the BBC.
