London: Israeli defence computers were hacked via a malicious email attachment, a computer security firm has revealed.
The email looked as if it had been sent by Israel`s Shin Bet secret service tricking several people into opening it, Seculert said.
According to a news website, hackers temporarily got control of 15 computers that are part of Israel`s defence forces following the attack.
Pro-Palestinian hackers are believed to be behind the attack.
Details about the attack were revealed by Aviv Raff, chief technology officer at Israeli firm Seculert, which helped to clean up after attack.
Raff said Palestinian involvement could be possible because of the attack`s similarity to another incident that took place in 2012, which too involved booby-trapped messages sent to Israeli government staff.
Raff said that the messages written in both the emails were written and formatted in a very similar style.
