Hacker Leaves Not Safe For Work Images

A fired IT manager hacked into his former employer's computer system and left some not-safe-for-work images: a cache of porn.

Walter Powell, 52, pleaded guilty to two counts of unlawful access to a computer causing a malfunction in Maryland court on Tuesday.

Powell had been fired from his job at the Baltimore Substance Abuse Systems, a city agency, in 2009, the Baltimore Sun reported.  Following his termination, prosecutors said he began hacking into the organization's computer system.

In one incident cited by prosecutors, Powell gained access to a chief executive's computerized presentation and replaced it with pornographic images.  The presentation was intended for the agency's board of directors.

Prosecutors are calling this Baltimore's first hacking trial.  Powell also pleaded guilty to one count of possessing a pass code without authorization.  A judge sentenced him to two years in jail, but suspended the sentence because of time served.  Powell was also sentenced to three years of probation and 100 hours of community service.
