DENVER, COLORADO (BNO NEWS) – A Colorado man was indicted on charges of attempting to corrupt a Transportation Security Administration (TSA) database, prosecutors said Wednesday.

Douglas James Duchak, age 46, of Colorado Springs, Colorado, knowingly transmitted code into the Colorado Springs Operations Center (CSOC) server, which loads data received from the federal government’s Terrorist Screening Database, and the United States Marshal’s Service Warrant Information Network.

Duchak worked at CSOC between the years 2004 and 2009 as a data analyst, responsible for updating information that was received from the government. On October 15, 2009, Duchak was informed that his employment at CSOC would be terminated as of October 30, 2009. He allegedly manipulated the system on October 22 and 23, 2009.

“While this threat was an attempted internal attack on a cyber-based system by a U.S. citizen, the FBI will invest the time, resources, and hard work necessary to pursue prosecution of these cases,” said FBI Special Agent in Charge James H. Davis. “The tampering with a computer that is used as a tool to protect National Security of the United States will not be tolerated.”

Duchak surrendered to U.S. Marshals Wednesday morning, and if convicted, he faces a maximum term of 10 years in federal prison, and a fine of not more than $250,000 for each of the two counts which he is indicted for.
