"Anonymous" WikiLeaks Supporters Claims Have Acquired Information for MasterCard Credit Cards

Wikileaks Cyberwar Mastercard and Visa

Hackers group Anonymous, which has been working diligently in support of WikiLeaks, claims to have acquired information for numerous MasterCard credit cards following its attack on MasterCard's website.

MyBankTracker says private info has indeed been compromised, emphasizing that the ongoing WikiLeaks cyber war "is getting personal."

MyBankTracker captured a screenshot of the numbers tweeted out by Anonymous, blurring out part of them to protect privacy. They appear to be credit card numbers and expiration dates.

Though the credit card tweet was indeed the last update before Twitter suspended the account, Twitter tells HuffPostTech it has no comment as to why the account was taken down.

This is getting personal. Operation PayBack has moved from attacking financial corporations to individuals. An unlucky group of MasterCard holders are in for an unpleasant surprise as hackers have posted individual credit card numbers.

At approximately 6:00 p.m. on Wednesday evening the twitter account, Anon_Operation belonging to the hackers acting on behalf of WikiLeaks posted this message:

Exposing the credit card numbers and last valid dates of nearly 10,000 user’s cards. The tweet was only up for approximately five minutes before it was taken down by twitter. Still, the damage is done. The risk of internet-savvy users to take screenshots of the information and duplicate it through the web is high.

Here is a screenshot MyBankTracker.com was able to get before the site was down. The numbers have been blurred to avoid further exposing this sensitive information. MyBankTracker.com suggests you closely monitor the activity on your card to make sure it has not gotten into the wrong hands.

MasterCard and Visa Sites Was Shutdown Because of DDOS Attacks.


One of the earliest followers of Anonymous, Gregg Housh, is intimately aware of, but claims no participation in, the latest Anonymous offensive, titled "Operation Payback." It managed this week to take down the websites of MasterCard, Visa, and the Swedish government over their refusal to support WikiLeaks or Mr. Assange. 'MasterCard died quick,' Gregg Housh, an unofficial spokesman for the hactivists known as Anonymous, says in an interview with the Monitor. 'Visa went down in 30 seconds.'

Mr. Housh sat with the Monitor on Dec. 10 – in what he said was his 37th interview of the day – to explain how, and why, a couple thousand kids have crippled some of the world's most prominent companies' websites. They have done so with an unprecedented voluntary botnet, a network of thousands of computers working in tandem to simultaneously bombard a website with hits.

With this voluntary one, the very interesting fact of it is, the second it’s changed, there’s no user interaction, no one cares. These people who are in the voluntary one are leaving their computers on on purpose. So there’s a ton of computers that that second start sending their requests. And that instantaneousness of it really is the thing that seems to be spiking the servers. They come crashing down under the initial load. Whereas with these other botnets and what not, some of them don’t have that initial gigantic hit. They have a sustained hit, but it’s not initially just oh-my-God-out-of-nowhere gigantic. I will tell you, before the voluntary botnet, they tried downing sites of this size, and they didn’t down a thing. So I really think the voluntary botnet is what’s doing it.
