A Massachusetts hacker has agreed to plead guilty to charges that he gained access to computer networks of a local police department and a community college and that he stole credit card information for thousands of people, the US attorney’s office said.
Cameron Lacroix, 25, of New Bedford was charged Monday with two counts of computer intrusion and one count of access device fraud, US Attorney Carmen M. Ortiz’s office said.
In a written plea agreement, Lacroix agreed to plead guilty to the charges and serve a four-year prison sentence.
Lacroix is well-known for hacking into Paris Hilton’s cellphone when he was a teenager.
Prosecutors allege Lacroix hacked into Bristol Community College’s server without authorization when he was a student there. Between September 2012 and December 2013, Lacroix allegedly stole log-in information for three professors. With the usernames and passwords, he changed grades for himself and two other students, Ortiz’s office said.
In addition, prosecutors said that in September 2012 Lacroix broke into a local police department’s private server and took copies of police and intelligence reports, arrest warrants, and sex offender information. He also allegedly hacked into the police chief’s e-mail account.
Prosecutors did not say which department was involved.
For two years, between May 2011 and May 2013, Lacroix also obtained stolen credit and debit card information for more than 14,000 people.
He also obtained other information, including account holders’ names, addresses, birth dates, and Social Security numbers for some of those people, Ortiz’s office said.
Lacroix’s plea hearing has not been scheduled.
In 2005, Lacroix pleaded guilty to charges that he hacked into Hilton’s cellphone and posted personal information online.
He also pleaded guilty to charges that he made bomb threats to high schools in Florida and Massachusetts.
He was sentenced to 11 months of detention at a juvenile facility and two years of supervised release.Jacqueline Tempera can be reached at jacqueline.tempera
