Flame controversy continues

The row over a highly sophisticated cyberspying worm called Flame continues. This week, President Obama was forced to dispute claims that the White House had leaked the fact it was behind the worm, which was found on computers mostly in Iran and is believed to have sent back huge amount of confidential information.

Obama was seen to gain politically in an election year from being touch on Iran but denied that his team would ever leak national security information. Meantime researchers discovered that the worm's authors had tried to kill any trace of the worm by sending out a "kill" command over the Internet - a feature that may have been behind the worm's ability to have stayed hidden for so long.
