British hacker linked to attack on Pentagon Twitter feed: sources

British hacker linked to attack on Pentagon Twitter feed: sources: The “CyberCaliphate” hacking group that attacked a Twitter account belonging to the Pentagon on Monday was founded by a Briton who was once jailed for hacking the personal address book of former British Prime Minister Tony Blair, according to government sources and private sector security experts.

U.S. and European government sources said investigators strongly believe that Junaid Hussain, 20, was the leader of CyberCaliphate, though they do not know if he was personally involved in hacking the Twitter (TWTR.N) and YouTube (GOOGL.O) accounts of the U.S. Central Command, which oversees military operations in the Middle East.

Hussain could not be reached for comment.

In 2012, Hussain was jailed for six months for stealing Blair’s address book from an email account maintained by one of Blair’s advisors. Hussain pleaded guilty to putting details of the address book online and making hoax calls to a counter-terrorism hotline.
