The Army had contracted with a private company to manage the system, which then subcontracted with Das in 2012 to lead the effort, according to the release.
In 2014, the contract was re-bid and awarded to another company, with a change date of Nov. 24, officials said.
Das inserted malicious code — commonly known as a “logic bomb” — in the days leading up to the changeover, officials said. The “progressively destructive nature” of this code took effect the day after the new contract took effect.
Officials had to fix the damage by removing the malicious code, restoring all information and features and reviewing the entire system to find any further malicious code, according to the release. The labor cost the Army about $2.6 million.
“Cyber-sabotage is not a prank. It is a very serious crime with real victims and real costs,” Bruce said. “In this case, the crime cost taxpayers $2.6 million. Thanks to great work by the investigators and prosecutor, Mr. Das is being held accountable for his criminal acts.”
