Well in case you missed it, the cyber element of Israel's current fight against Hamas in the Gaza strip is well underway. No, Hamas hasn't tried to send a reverse-engineered Stuxtnet style worm into Israeli nuclear facilities (though Israel has been live tweeting this conflict like crazy). A third party has jumped into the fray and is taking aim at Israel.
Anonymous, the online activist collective (we're deliberately not using the term hacktivist) is hitting Israeli government sites - and possibly Mastercard's Israeli site -- with denial of service attacks and apparently published documents with personal details of 5,000 Israeli government officials in an operation organized under the Twitter hashtag, #OpIsrael.
This might be the first time that a third party has jumped into state versus whatever-you-want-to-call-Hamas (quasi-government, terrorist group?) conflict to fight in the cyber arena. We've seen what were likely nation-backed "civilian" hackers committing cyber attacks against Georgia during Russia's 2008 invasion there, but this adds a new twist to that angle. Sound off in the comments if you can think of a similar instance.
Still, it remains to be seen what, if any impact on the conflict Anonymous' actions will have.
