Police said that the suspect sent a spam e-mail containing the Trojan virus to the company.
“It’s called a Trojan virus, and it’s an email that basically you open up and once you open it up that allows them access to your computer and they’re able to obtain your personal information,” Trooper Stefani Plume, of the Pennsylvania State Police told Pittsburgh’s CBS Local.
The hacker then had access to the company’s accounts and passwords. He used that access to issue himself five fraudulent checks. The checks were cashed in various states.
At this time, police have not made any arrests in the case.
