Hackers Likely Stole FBI Call Logs From AT&T That Could Compromise Informants


A breach of AT&T that exposed “nearly all” of the company's customers may have included records related to confidential FBI sources, potentially explaining the Bureau's new embrace of end-to-end encryption.

This separate situation exposed call and text logs for a smaller group of specific high-profile targets, and in some cases included recordings as well as information like location data. If agents were following investigative communication strictly, though, the stolen AT&T call and text logs shouldn't pose a big threat, says former NSA hacker and Hunter Strategy vice president of research Jake Williams. Standard operating procedure should be designed to account for the possibility that call logs could be compromised, he says, and should require agents to communicate with sensitive sources using phone numbers that have never been linked to them or the US government.
