A search in the news of recent years proves the same thing.
In 2011, 114 Israeli sites were hacked, in 2012 the number of hacked sites in “Op Israel” operation has reached 663, in 2013 a general disorder in official sites of Zionist regime has claimed by “Quds freedom” hacker group and in 2014 the “Anonymous” hacker group has released a report of hacking 500 Israeli sites.
The “Gaza Cyber Spirit” hacker group could put about 600 Israeli sites out of service in the past year. So we should wait for this year’s Quds Day to know how many targets hacker groups will have against these hostile regime sites.
