Hacker Publishes Customer Data Allegedly Obtained from 79 Banks

A hacker that goes by the name of Reckz0r claims to have gained access to the systems of 79 banks and, to prove it, he has released a few hundred record sets that allegedly belong to the financial institutions' customers.

Even though the data dump is entitled “Visa and Mastercard hacked”, a Twitter post reveals that in fact the victims are 79 banks.

“Actually, I didn't hacked VISA & Mastercard, I hacked the banks,#Chase..etc. I penetrated over 79 large banks, I've been targetting these banks since 3 months,” he explained.

The information he published comprises credit card types, names, addresses, postal codes, phone numbers, country codes, and email addresses.

While the file he posted on his Twitter account is only 200 kilobytes in size, according to trouw.nl, a 50 gigabyte file is making the rounds, the situation currently being investigated by Visa and MasterCard.

Experts from Belsec believe that the details may be obtained from a payment processor.

We haven’t been able to find the 50 gigabyte file, but we came across the same data dump that Reclz0r published on an Arab hacking forum where it had been posted about a week ago by a hacker team called Group 404 Hack, which claimed to have leaked the information from an Israeli data center.

Reclz0r describes himself as a former member of Anonymous and the creator of the SpexSecurity collective. He also reveals to have certain connections with the UGNazi collective.

“I've realized that I am doing this [expletive] for nothing. I am officially a whitehat. I will use my intelligence for good. I've done over 50 large hacks, and leaked many essential information, I am sorry if I harmed you, or affected your families. This is my departure from the hacking scene. I am no-longer a hacker, I'm a whitehat,” he wrote a week ago.

In the past few weeks he has been highly active, allegedly revealing the true identities of famous controversial hackers such as The Jester and Hex00010.

He has also taken credit for breaching the systems of organizations such as Sony, the Pakistani Cyber Police and the New South Wales government.
