The hacker group Anonymous released 38,000 private e-mails belonging to a retired special agent supervisor and cybercrime investigator at the California Department of Justice (DoJ), Fred Baclagan.

The messages reveal detailed information about computer forensic techniques and investigation protocols, the group said in a notice posted to Pastebin. Anonymous also said it leaked several dozen of Baclagan's voicemails and SMS text message logs, along with his personal phone number and address.

"Possibly the most interesting content in his e-mails are the IACIS.com internal e-mail list archives (2005-2011) which detail the methods and tactics cybercrime units use to gather electronic evidence, conduct investigations, and make arrests," said the group.

"There are discussions about using EnCase forensic software, attempts to crack TrueCrypt encrypted drives, sniffing wireless traffic in mobile surveillance vehicles, how to best prepare search warrants, and subpoenas, and a whole lot of clueless people asking questions on how to use basic software like FTP."

“The information in these e-mails will prove essential to those who want to protect themselves from the techniques and procedures cybercrime investigators use to build cases,” Anonymous said.
