Personally, I'd love to see Mossad post names and addresses of every "hacker" involved on a public website and do nothing else.
That would send the loudest message possible.
and yeah this would own, except that you are buying into this weird Mossad boogeyman brand: as I talked about last page, Israel's excellent and well-practiced cyberwarfare corps is, I believe, part of their military intelligence service, though I'm not exactly sure where. Flame?, Stuxnet, and
Duqu were examples of their offensive capabilities, but they're also constantly dealing with more routine attacks.
This is part of why I think it's so ridiculous to swallow Anonymous' chest-thumping and get all oooh wooo Mossad: when you've already got a more serious local enemy text messaging your officers to tell them that Tel Aviv will soon be a sea of flame, a gang of badly organized cyber-graffiti artists whose bark has generally greatly exceeded their bite are hardly something to get worked up about.
