The force said it launched an investigation today after being made aware that the phone calls might have been breached. A force statement said: "We are aware of an issue whereby telephone conversations relating to the anti-terror hotline were recorded. Officers are currently looking into the matter and appropriate action will be taken. The announcement from the force came as a recording said to be a "prank call" to MI6 was uploaded on YouTube, attributed to the "hacktivist" group TeaMp0isoN. The group were said to have compromised a server from Malaysia to record conversations before Trick, the leader of the group, allegedly called MI6 offices in London. Group leader Trick emailed the Press Association: "The phone denial of service was done via a custom script for Asterisk which was installed on an overseas server. The conversation was tapped into via a private phreaking method, their phone system is old and we found a way to get in via basic but private phreaking technique. In response to the Scotland Yard statement, -TeaMp0isoN tweeted: "OH REALLY NOW."
