New submitter 9re9 writes "The NY Times describes what may be the beginning of an actual cyberwar between a pro-Palestinian group and Israeli companies, specifically El Al and the Tel Aviv stock exchange. From the article: 'A hacker identifying himself as oxOmar, already notorious for posting the details of more than 20,000 Israeli credit cards, sent an overnight warning to Israel's Ynet news outlet that a group of pro-Palestinian cyberattackers called Nightmare planned to bring down the sites in the morning.' Though the article is skimpy on technical details, the group appears to have engaged merely in a DDOS attack. Hamas praised the attack as opening 'a new resistance front against Israel.' Is this the first acknowledged cyberwar?"
