A former computer network administrator has pleaded guilty to computer hacking and identity theft.
The Santa Clara County District Attorney's Office announced a former computer network administrator has pleaded guilty to computer hacking and identity theft, among other charges.
Andrew Madrid, a 34-year-old San Jose man, pleaded guilty Friday to 14 counts of second-degree burglary, four counts of computer hacking, three counts of identity theft and two counts of possession of methamphetamine for sale in connection with crimes that took place between Sept. 1, 2006 and March 6, 2008.
Madrid, a former network administrator for a Sunnyvale technology company, targeted companies in the San Jose area and committed a variety of crimes, according to the district attorney's office.
Prosecuting attorney Ben Field said Madrid gained access to several local companies by posing as a security guard or information technology staff person. During off hours, he would then load his truck with expensive equipment from those companies, Field said.
Madrid also managed to hack into computer networks of victim companies to steal data and take company passwords, and stole identities to commit crimes, according to Field.
"This is one of the most complex and sophisticated computer crimes the office has prosecuted," Field said.
Additionally, Madrid placed fake bar codes on products at retail stores to pay less for expensive computer equipment, Field said.
The guilty plea followed an investigation by five law enforcement agencies, including the Sunnyvale Department of Public Safety, the Los Gatos Police Department, the Santa Clara Police Department, the San Jose Police Department and the REACT Task Force.
Madrid is scheduled to be sentenced before Judge Douglas Southard on Jan. 22, 2009.
