Officials of the Inspector General of the State of Ohio published a 50-page investigative report (PDF, of the incident that took place back in 2015, but now came in public domain.

According to the reports, five prisoners from the Marion Correctional Institution (MCI) secretly got hold on two computers, then they hid the computers under the suspended ceiling in the service room, after that they broke the prison network, and got the opportunity to go in prohibited zone and engaged in illegal activities on the Internet. All of this became possible just due to the fact that the prisoners were made to work under the Green Initiative program, in which they were engaged in the recycled different electronics.

Administrators of MCI began to notice something strange in the summer of 2015: an account belonging to one of the contractors of the prison began to exceed the daily quota of traffic. Then similar behavior began to show the accounts of other employees, including on weekends, when these employees were not at all in the workplace. Worse, a few days later, these employees began to make attempts to evade the proxies that monitored the traffic. Administrators’ suspicions gave rise to a full-fledged investigation, during which strange activity could be traced to a computer that appears in the report as -lab9-. This name did not fit into the internal naming system at all.
