The intrusions into former CBS News correspondent Sharyl Attkisson's computers constitute the narrative spine of the reporter's new book "Stonewalled: My Fight for Truth Against the Forces of Obstruction, Intimidation, and Harassment in Obama's Washington." In October 2012, right in the midst of the Benghazi story ... a person who's identified as "Jeff" warns Attkisson: "I've been reading your reports online about Benghazi. It's pretty incredible. Keep at it. But you'd better watch out." So CBS News hires an independent computer analyst whom Attkisson identifies as "Jerry Patel." He finds a massive amount of suspicious activity in the computer. Intrusions of this caliber, concludes "Patel," are "far beyond the the abilities of even the best nongovernment hackers." In summing up, Attkisson writes, "Everything Patel has found serves to confirm my January source and analysis. Patel tells me that only a few entities possess these skills. One of them is the U.S. government. [Computer security specialist] Don Allison ... takes a close look at Attkisson's iMac. The results: "While a great deal of data has been expertly wiped in an attempt to cover-up the deed, Don is able to find remnants of what was once there. There's key evidence of a government computer connection to my computer. A sort of backdoor link that leads to an ISP address for a government computer that can't be accessed by the general public on the Web. It's an undeniable link to the U.S. government."
