The California computer science student who hacked various women’s computers for the purposes of “sextortion”—including Miss Teen USA 2013, Cassidy Wolf—has been sentenced to 18 months in prison. The sentence comes after Jared James Abrahams pleaded guilty to one count of computer hacking and three counts of extortion last November.

According to a press release published Monday afternoon by the United States Attorney’s Office for the Central District of California, Abrahams “used the nude photos to extort victims by threatening to publicly post the compromising photos or videos to the victims’ social media accounts—unless the victim either sent more nude photos or videos, or engaged in a Skype session with him and did what he said for five minutes.”

As Ars Deputy Editor Nate Anderson wrote last year, Abrahams became decently adept at using remote administration tools (RATs), a malware used to spy on victims.

Not surprisingly, Abrahams was a regular user of hackforums.net, which features a large RAT forum that Ars profiled earlier in 2013. As cutefuzzypuppy, Abrahams asked for plenty of help distributing software like DarkComet to victims, since he "suck[ed] at social engineering" and needed to find better ways to spread his spyware.

He also announced his successes. On May 17, 2012, he told the RAT community at hackforums.net: "Recently I infected a person at my school with darkcomet. It was total luck that I got her infected because I suck at social engineering. Anyway, this girl happens to be a model and a really good looking one at that :D. I was hoping I could use her and her facebook account to further spread my darkcomet rat. I want to mass message all her friends on facebook but I have no idea what to message them to get them to download the rat. Any ideas or suggestions would be greatly appreciated :)."

In Monday’s press release, the US Attorney’s Office also offered this warning, which should be obvious to anyone by now: “Computer users should cover their webcams when they are not in use.”
