Anonymous hacker group attacks Israeli websites 16 Nov 2012 Hacking group Anonymous has launched a series of cyber attacks against websites in Israel. Data bombardments briefly knocked some sites offline and led to others being defaced with pro-Palestinian messages. The OpIsrael campaign was launched by the hacking collective in retaliation for attacks on Gaza. The cyber attacks come as the Israeli army updates its web campaign adding "achievements" and "badges" for regular visitors. Anonymous said it had launched the OpIsrael campaign following threats by the Israeli government to cut all Gaza's telecommunication links. This, said the group in a statement posted to the AnonRelations website, "crossed a line in the sand".
