Anonymous breached FEMA servers and pulled information on hundreds of agency contacts worldwide. According to the hacker collective, it was in response to Homeland Security training exercises that centered on a fictional version of the hacker collective. In a document containing non-sensitive data pulled from FEMA's system, Anonymous wrote that the attack was designed as a reminder that it would continue to fight against government efforts to police the internet.
The document, which was sent to me from a Tormail account this morning and since been released online, contains a dump of email addresses and contact info for hundreds of contacts: police and fire departments nationwide, FBI special agents, a "Bioterrorism Coordinator Chair," scores of private contractors, and some international contacts at agencies concerned with police work, counterterror efforts, and disaster response.
The dump contains a table of user IDs and MD5 hashes of corresponding passwords, presumably for DHS's Integrated Security and Access Control System. Also included is a small set of what appears to be descriptions of training exercises (sample title: "Monitoring Weather Conditions and Taking Necessary Precautions") that date from 2004-2007.
"Anonymous has purposefully redacted logins, passwords, SSNs and other details that might genuinely endanger the United States from this document, our intent is not to harm, merely to issue a firm warning," the document's intro states.
I've reached out to the members who initially sent the file to me, and will update when I hear back. I reached out to FEMA, and am waiting to hear back. I'll update when I do.
