An Ohio IT contractor has pleaded guilty to breaking into his former employer's systems and causing nearly $1 million worth of damage after being fired.

Maxwell Schultz, 35, impersonated another contractor to gain access to the company's network after his credentials were revoked.

Announcing the news, US attorney Nicholas J. Ganjei did not specify the company in question, which is typical in these malicious insider cases, although local media reported it to be Houston-based Waste Management. The Register contacted Waste Management for clarity, but it did not respond.
