CONCORD, N.H. (AP) — A man has pleaded guilty in federal court to hacking into computer accounts for a New Hampshire town’s police department and offices, and a drug treatment center.

The U.S. Attorney’s office said Wednesday that Wayne Kenney Jr., 31, of Hooksett, was arrested by an Auburn police officer in 2015 on a heroin possession charge. He was required to attend drug counseling at the Farnum Center in Manchester.

That year, Kenney “engaged in a retributive course of action” that involved hacking into the computer accounts, prosecutors said in a news release. He deployed malicious “keylogging” software, stole employees’ log-in credentials and defaced their accounts. He also created pop-up messages to “pray for the death” of the officer who arrested him, prosecutors said.

Kenney also disabled a Farnum Center link that would have provided website visitors access to information about alcohol and drug treatment assistance. He also changed their 24-hour emergency drug hotline phone number so that anyone calling for help would be re-routed to a number associated with adult entertainment services, prosecutors said.

“The events giving rise to this case happened over five years ago,” his attorney, Amy Spencer, said Thursday. “My client was going through some very difficult personal issues at that time that he has since successfully worked very hard to overcome. He is remorseful for his actions, is taking responsibility for them, and is a different person now than he was at that time.”

He pleaded guilty to unauthorized access to a computer and damage to protected computers and is scheduled to be sentenced on March 2, 2021.
