Israeli Intelligence mouthpiece DEBKAfile succeeded in restoring service today after a period of outage.

DEBKAfile’s two sites in English and Hebrew came under a massive cyber attack on our servers at the moment Israeli ground forces crossed into the Gaza Strip Saturday night, Jan. 3. The attackers tried and failed to block and replace our content. We did our utmost to restore service as quickly as possible and return to full operation.

DEBKAfile wasn’t the first site hit.

Computerworld reports earlier activity aimed at Israeli business and web domains:

The conflict raging in Gaza between Israel and Palestine has spilled over to the Internet.

Since Saturday (12/27), thousands of Web pages have been defaced by hacking groups operating out of Morocco, Lebanon, Turkey and Iran, said Gary Warner, director of research in computer forensics at the University of Alabama at Birmingham.

The defacements have primarily affected small businesses and vanity Web pages hosted on Israel’s .il Internet domain space. One such site was that of Israel’s Galoz Electronics Ltd. On Wednesday, the hacked Web site read “RitualistaS GrouP Hacked your System! ! ! The world isn’t insurance! ! ! For a better world.”

Other attackers have placed more incendiary messages condemning the U.S. and Israel and adding graphic photographs of the violence. Warner said he has seen no evidence that any Israeli government site has been hit by these attacks, although they have been targeted.
