Summary: More than 79 banks have been breached, claimed a hacker on Twitter. Following a data release on Tuesday, he said he has more than 50 gigabytes of U.S. and foreign bank data in his hands.

Update: see below.

A hacker, who claimed on Twitter to have illegally accessed the networks of dozens of large banks, has released a vast cache of personal information relating to Visa and Mastercard credit card data.

More than 1,700 separate account details were included in the cache.

From the data included in the data dump: customer names, the debit or credit card type — Visa or Mastercard — along with postal addresses, phone numbers, and email addresses are all included.

“Grey-hat” hacker Reckz0r — who oddly enough also goes by the name “Jeremy” — said on Twitter that he had targeted 79 banks for around three months.

The data breach does not appear limited to the United States. Foreign banks and account details are noted, including from the United Kingdom and Canada.

Sounds more like he hacked to some webstore and got the information of these 1700 (or some more). Now trying to blackmail the banks to pay for the information.

What a lovely thing to do.

That data what he said he took, was already published on an Arabian Website as early as May 6th. I doubt that this "Jeremy" has done it himself or is he just taking credit for someone else Hack ??
