More malicious activity on CDOT computers reported

Eight days into a ransomware attack, state information technology officials detected more malicious activity on computer systems at the Colorado Department of Transportation.

Eight days into a ransomware attack, state information technology officials detected more malicious activity on the Colorado Department of Transportation computer systems Thursday.

A spokeswoman for the Governor’s Office of Information Technology says this is a variation of the same ransomware that hit computers last week, when criminals demanded a Bitcoin payment in exchange for freeing up the software.

Before Thursday's activity, 20 percent of CDOT's 2,000 or so computers had been cleared from the ransomware. All of those computers are down once again.

The Office of Information Technology said CDOTs Traffic Operations Center wasn’t impacted. The attack is mostly contained to CDOT’s “back office” system, which includes H.R., and finance payroll.

Employees have been ordered to shut off their computers until the source of the problem has been found. The network has been disconnected from the internet for now, and many employees are working on a pen and paper system.

The impact of the attack is still unknown, but CDOT says this activity is equated to someone getting into the building who shouldn't have.
