HP-hired investigators searching for the source of boardroom leaks allegedly tried to plant a trojan horse program on a CNET reporter's laptop, but apparently the attempt failed because the reporter was running Linux instead of Windows, according to Groklaw's Pamela Jones. Details are sketchy but the New York Times reported:
"The detectives also tried to plant software in the computer of a CNET reporter that would communicate back to the detectives, people briefed on the company review said… Representing themselves as an anonymous tipster, the detectives e-mailed a document to a CNET reporter, according to those briefed on the review. The e-mail was embedded with software that was supposed to trace who the document was forwarded to. The software did not work, however, and the reporter never wrote any story based on the bogus document."
