Prisoners made computer out of trash...

The incident occurred in 2015 but has now been made public by the State of Ohio's Office of the Inspector General, which published a 50-page report [PDF] on Tuesday, following almost a year-long investigation.

According to the report, a prison work program has backfired two inmates of Marion Correctional Institution in Ohio, Florida, who smuggled computer parts from an e-waste recycling workshop and built two clandestine computers out of them.

The unsupervised inmates later hid the computers behind a plywood board in the ceiling of a training room, and then connected those working PCs to the Ohio Department of Rehabilitation and Correction (ODRC) network to access the Internet.

But once the inmates got online, unsurprisingly, they used their skills to break the law.

The prisoners accessed the internal records of other inmates, created inmate passes for restricted areas, accessed websites with information about manufacturing drugs, weapons, and explosives, and apply for credit cards under another prisoner's name for a planned tax fraud scheme, Ohio's government watchdog said.

Besides this, the forensics team also found "self-signed certificates, Pidgin chat accounts, Tor sites, Tor geo exit nodes, ether soft, pornography, videos, VideoLan, virtual phone, and other various software."

The scheme was discovered after prison technology employee Gene Brady alerted about unusual levels of internet activity on a contractor's account on days when the employee was not scheduled to work.

Ultimately, a total of five inmates were identified as being involved with the hidden computers during the investigation:

Stanislov Transkiy – Executive committee chairman of Recycling.
Leeshan McCullough – Chairman of aquaculture.
Robert Cooper – Chairman of horticulture.
Matthew Brown – Chairman of environmental education.
Adam Johnston – Executive committee treasurer.

All the five inmates have now been separated and moved to other correctional facilities.
