An audio recording of a conference call between the FBI and Scotland Yard has been posted on YouTube by Anonymous.
BBC and other sources report that the agencies have confirmed the authenticity of the 16 minute audio recording.
The 1/20/12 call between the agencies, including at least one M15 (Brit CIA) participant, was to discuss progress of investigations into Anonymous, Lulzsec, Antisec, etc.
Also published by Anon was an email announcing the call and inviting participation from the agencies, including names and email addresses of recipients.
While the content of the recording doesn't seem to include any major revelations, the mere fact of the intercept and it's publication is causing some hubris.
As one anon commented on Twitter:
"The FBI might be curious how we're able to continuously read their internal comms for some time now."
The security breach is under investigation, according to authorities.
