Andrew James Miller, 23, of Devon, Pa., was recently sentenced to 18 months in prison for a scheme to sell access to hacked computers, including two at the Lawrence Berkeley National Laboratory in California (h/t Computerworld).

According to court documents, from 2008 to 2011, Miller hacked into several computers on commercial, education and government networks, obtained login credentials, and sometimes installed backdoors that provided root access to the compromised computers.

He and co-conspirators then sold access to the compromised computers.

In 2011, Miller offered an undercover FBI agent access to two supercomputers at the Lawrence Berkeley National Laboratory in California that were part of the National Energy Research Scientific Computing Center (NERSC). He asked for $50,000 in payment.

While the FBI didn't purchase that access from Miller, it did buy access to servers at Massachusetts telecom provider RNK Communications and at Colorado ad agency Crispin Porter and Bogusky. Miller also sold the FBI a database of thousands of login credentials allegedly stolen from Texas ISP Layered Tech, according to Computerworld.

Miller, who was previously convicted in 2004 of being involved in writing malware, pled guilty to conspiracy and computer fraud on August 26, 2013.
