One of the latest Facebook groups in Israel, numbering over 60,000 members, has been under attack by unknown Arab hackers since last night. Several Israeli Facebook accounts belonging to members of the group have been compromised, and so far users have not been able to regain exclusive control of their accounts.
We are not clear how the attackers gained access, due to regretfully limited cooperation between us and the group, but we are told users who are suspected of being compromised have been temporarily removed from the group, which is now in read-only mode.
So far, we’ve got the identity of one of the hackers, one Omar Jisrawi. His profile has him located in Hebron, and is a self-proclaimed hacktivist at Anonymous.
Currently, our primary suspect is a collaboration between the GHT, or Gaza Hacker Team and AnonGhost, both of whom recently took responsibility for several attacks on Israeli sites. We believe there is a connection between this and the alleged attack on the IDF’s computers, discovered by Blue Coat systems. Certainly Blue Coat seems to think so, because we logged several of their IP addresses in honeypot links we spread through the group.
As always, we advise our readers to implement two-step authentication in on your online accounts, if you haven’t done so already.
We will continue to update as the story develops.
