Many of you will probably remember the CCTV footage of alleged assassins, dressed in disguises of tennis gear, and carrying racquets, as they strolled through a luxury hotel when it was shown early last year.

Mahmoud al-Mabhouh, a senior Hamas official, was murdered at Dubai's al-Bustan Rotana hotel by a professional assassination team of 11 people.

The news of the killing made headlines around the world, including in Britain where there was a diplomatic scuffle when it was revealed that the suspects had apparently used cloned British passports to disguise their true identities.

Many people pointed the finger of suspicion at Mossad, Israel's foreign intelligence agency.

Now, a new report by investigative reporter Ronen Bergman published in GQ Magazine, gives the story a computer security spin.

Bergman claims that the assassination team were able to track al-Mabhouh's movements and plans because they had planted a spyware Trojan horse on his computer. This gave them the ability to monitor his email communications and other online activities.

Clancy novel stuff.
