As we know that Jews strike Gaza again last week. It's make another cyber attack to Israeli government, it's called #OpIsrael on Twitter. Hacker Anonymous claimed that they hacked many Israeli bank accounts, causes $3-plus billion losses. Anonymous also claimed they want to wipe Israel out from the internet.

Last week, Israeli airstrikes once again hit targets in Gaza, officially breaking a ceasefire established last November (although cross-border clashes have informally breached the ceasefire in recent months, leaving four Palestinians dead). In retaliation, Anonymous relaunched #OpIsrael this weekend, and according to an Anonymous spokesperson offering a partial damage report, 60,000 websites, 40,000 Facebook pages, 5,000 twitter accounts and 30,000 Israeli bank accounts got hacked, causing an estimated $3-plus billion damage, the hacker collective claim. “Not bad for 24 hours,” Anonymous noted.
