CBS's Sharyl Attkisson Upset Over Hacking

Who targeted her and her employer? Mr. Holder?

CBS investigative reporter Sharyl Attkisson on Monday said she is "outraged" her computer was hacked and called it "a very serious and disturbing matter."

Attkisson told "CBS This Morning" she reported her concern that her work and personal computers were being compromised to CBS News management in January, and they hired a cyber security firm to conduct an investigation. CBS News on Friday said Attkisson's computer had been compromised and accessed "by an unauthorized, external, unknown party on multiple occasions" in late 2012.

"There were signs of unusual happenings in my home for many months and that included odd behavior of both my work and my personal computers," Attkisson said. " One example was the computers began turning themselves off and then back on again during the night. I was able to verify and obtain some of the information on the suspicious activities and I reported that to CBS News management in January."
