Credit card cracker has struck before

From MSNBC: “MSNBC.com has learned that the hacker who
recently tried to extort CreditCards.com has been at it before.
Another site victimized by the hacker has stepped forward,
telling MSNBC.com it suffered a similar extortion several
months ago. The hacker followed the exact same routine,
demanded $20,000, and used the same e-mail address as the
CreditCards.com hacker. What’s more, the owner of this site
told MSNBC.com the hacker is suspected in more than a dozen
other hacking extortion attempts.”
