CBS Reporter's Computer Breached by 'Unknown Party'

CBS News investigative reporter Sharyl Attkisson's computer was accessed by an "unauthorized, external, unknown party" last year, the company concluded after an investigation.

CBS News issued the following statement, which Attkisson tweeted in several parts on Friday morning:

“A cyber security firm hired by CBS News has determined through forensic analysis that Sharyl Attkisson’s computer was accessed by an unauthorized, external, unknown party on multiple occasions late in 2012. Evidence suggests this party performed all access remotely using Attkisson’s accounts. While no malicious code was found, forensic analysis revealed an intruder had executed commands that appeared to involve search and exfiltration of data.

This party also used sophisticated methods to remove all possible indications of unauthorized activity and alter system times to cause further confusion.
