A cyber-attack of various government websites by groups of hackers is allegedly underway Tuesday morning, as was warned using social media. A pastebin message begins with, “Let’s hurt them where it’s hurts the most” and the group promises, “Anonymous will make sure that’s this May 7th will be a day to remember” in what the group titles as, #OpUSA. The high profile list of targets includes, Bank of America, Citibank, White House websites, the FBI, among others.

Another message seemingly from a member of one of the hacktivist collectives known as Anonymous states “America you have committed multiple war crimes in Iraq, Afghanistan, Pakistan, and recently you have committed war crimes in your own country. You have killed hundreds of innocent children and families with drones, guns, and now bombs. America you have hit thousands of people where it hurts them, now it is our time for our Lulz. For this you shall pay. Obama you have seen the over three billion dollars worth of damage we have done to Israel in operation Israel. It hasn’t even been a few weeks and the anonymous collective has gotten stronger since then.”

As federal government agencies brace themselves for a large-scale attack, a "Hacker's News Bulletin" is linked on Twitter that claims to be a running "List of Websites,Email Accounts affected under #OpUSA; Updating list as defaced,hacked or down."

"A group of mostly Middle East- and North Africa-based criminal hackers are preparing to launch a cyber attack campaign next week known as “OpUSA” against websites of high-profile US government agencies, financial institutions, and commercial entities," reports security blog Krebs on Security. "But security experts remain undecided on whether this latest round of promised attacks will amount to anything more than a public nuisance."

Last month, Anonymous launched #OpIsrael, which promised to “wipe Israel off the internet,” and well, that turned out to be a big #OpFail.
