Cameron Lacroix, 25, who served 11 months in a juvenile detention facility for stealing photos from Paris Hilton's cell phone almost a decade ago, recently pled guilty to several new hacking charges (h/t Krebs on Security).

Lacroix pled guilty to two counts of computer intrusion and one count of access device fraud, in connection with cyber attacks on a college and on enforcement agencies, as well as the theft of thousands of credit, debit and payment card numbers.

Between September 2012 and November 2013, while Lacroix was enrolled as a student at Bristol Community College, he allegedly hacked into the college's servers, and used login credentials stolen from three instructors to access the college's grade recording system in order to change his own grades as well as those of two other students.

In September 2012, Lacroix also allegedly hacked into a Massachusetts police department's server and accessed the chief of police's email account.

From August 2012 through November 2013, Lacroix is accused of repeatedly hacking into law enforcement servers that held police reports, intelligence reports, arrest warrants and sex offender information.

Between May 2011 and May 2013, Lacroix allegedly obtained more than 14,000 accounts holders' payment card data. In some cases, he also obtained other information connected to those account holders, including names, addresses, birthdates, Social Security numbers, email addresses, bank account and routing numbers, and transaction records.

If Lacroix's plea agreement is accepted by the court, he will be sentenced to four years in prison to followed by three years of supervised release.
