Sounds unlikely...
Not wanting to sound paranoid, but: Possibly this is what Mossad wants everyone else to think, rather than what actually happened. Why would you need to put a trojan onto a laptop when you have access to its hard drive already? Why not just image the disk? Also, it's pretty unlikely that a diplomatic laptop was unencrypted, so how did they gain access to the disk?
I am reminded of the enigma encoded message that was sent to the Mexicans offering them arms to fight against the US, this was decoded in the UK, but they staged a break in at the German embasy to make it look like it had been stolen. Knowledge that enigma had been cracked would have been very bad for the war effort.
