Victims of a data breach at the security analysis firm Stratfor apparently are being targeted a second time after speaking out about the hacking.
Stratfor said on its Facebook page that some individuals who offered public support for the company after it revealed it was hacked "may be being targeted for doing so."
The loose-knit hacking movement "Anonymous" claimed Sunday through Twitter that it had stolen thousands of credit card numbers and other personal information belonging to the company's clients. Anonymous members posted links to some of the information Sunday and more Monday.
Stratfor, based in Austin, Texas, said its affected clients and its supporters "are at risk of having sensitive information repeatedly published on other websites." The company is communicating through Facebook while its website remains down and its email suspended.
A message posted online Monday by a group asserting it spoke for Anonymous mocked victims who spoke to the Associated Press about learning that their credit card information had been stolen and used to make unauthorized charitable donations. The message also ridiculed someone who criticized the hacking on Facebook, saying "we went ahead and ran up your card a bit."
