Shawn Carpenter

Who is Shawn Carpenter?

Shawn Carpenter is an American Navy veteran and whistleblower who tracked down a Chinese cyberespionage ring that is code-named Titan Rain by the FBI. He came to national attention when his story was reported on in the September 5, 2005 issue of Time magazine.

Carpenter was an employee of Sandia National Laboratories, investigating security breaches in its networks. However, upon tracking several breaches of Sandia, Lockheed Martin Corporation, Redstone Arsenal, and even NASA, dating back to 2003, Carpenter noticed patterns that began to appear to link the attacks to a single group. He was impressed by the meticulous, voracious and incredibly fast manner in which the hackers operated. Such observations led him to alert the federal government of his findings.

The Titan Rain hacking operation was first reported in an August 25, 2005 Washington Post article by Bradley Graham, which didn't mention Carpenter. Graham listed anonymous governmental officials as his sources.

After informing his supervisors of the breaches, he was told that his only concern should be Sandia computers, and to drop the issue.
