Anonymous has reportedly made good on its threats to expose the personal information of members of the Ku Klux Klan in protest of the Ferguson, Mo., grand jury ruling not to indict Darren Wilson in the fatal shooting of Michael Brown.

According to a report in Raw Story, the hacker collective claimed to have taken over the Klan’s Twitter account and within a couple of days posted to Pastebin links to what is reported to be personal data — including credit card information, Social Security numbers and names — related to Klan imperial wizard, Frank Ancona, whose group allegedly had threatened to use “lethal force” against protesters in Ferguson.

In a Youtube video the hacktivists said it would “target any Missouri government or bank sites now, so you better increase your security.”
