Computer security experts tell Media Matters that the report of a federal investigation into Sharyl Attkisson's claims of computer hacking, which found no evidence of a remote intrusion, suggests that Attkisson's computer may have been contaminated by a private technician who reviewed the computer for her. Attkisson, a former CBS News reporter who now writes for the Heritage Foundation's Daily Signal, has claimed that her computers were hacked under an alleged federal effort to monitor her following her critical reporting of the Obama administration. But the investigation from the Justice Department's Office of the Inspector General, based on an examination of her personal computer, found that the OIG "was not able to substantiate the allegations that Attkisson's computers were subject to remote intrusion by the FBI, other government personnel, or otherwise," according to an abbreviated report of the review that was entered into the congressional record when Attkisson testified before Congress on January 29. Computer security experts contacted by Media Matters reviewed the OIG report and explained that the findings revealed that at least one of the private technicians used by Attkisson likely contaminated any evidence that may have been on her computer.
