STATESVILLE, N.C. – Seven students at North Carolina’s Lake Norman High School face criminal charges for allegedly hacking into the district’s computer system and accessing their classmates’ computers.

The male students, who ranged in age from 14 to 18, were charged with accessing computers without authorization after a breach Sept. 1 that school IT professionals quickly recognized and shut down, Fox 46 reports.

School officials realized someone hacked into some students’ laptops using an administrative password and their school-issued computer. The initial hacker passed the administrative password to other students, and the group manipulated files, activated webcams and fiddle with their classmates’ devices, Iredell Sheriff Darren Campbell told the Statesville Record & Landmark.

Campbell said there was no indication personal data, tests or grades were accessed.

The students charged include Martin J. Edmund Jr. 17, Gregory Matthew Torney, 17, Jake Donnelley Leffew, 18, Grayson Noble Baker, 16, Joshua Stephen Miller, 17, as well as two 14-year-old boys who were not identified by the news site.

The students were suspended from school, and petitions were filed against the two juveniles. The others were arrested last week and released to their parents with court dates scheduled for November, according to Fox 46.

The student data breach certainly isn’t a first.

Juan Ambriz, 18, was charged with alteration of a computer database in May for allegedly changing 200 grades at Dixon High School in California over a four month period. Numerous students were suspended in the ordeal because they allegedly paid Ambriz to improve their grades.

The scam went unnoticed because the changes were “pretty thoughtful and careful,” Dixon superintendent Brian Dolan told the Sacramento Bee.

Eric Walstrom, a Staten Island 16-year-old, was also arrested this spring for hacking into the computer system at New Dorp High School to change his own grades after learning advanced computer programing at an elite summer camp, the New York Post reported in February.

Walstrom bypassed the school’s password barrier and software security using a school computer then set up a network to access the system from his smart phone, which he did to improve his grades and access his transcript. He was busted when school officials noticed the unauthorized access and called police.

“You’d think a kid smart enough to hack his school’s computers would already have good grades,” a law enforcement source told the news site. “Maybe the DOE should hire him to expose weaknesses in their security firewalls.”

The teen was charged as adult with forgery, computer trespass, unauthorized use of a computer, computer tampering and criminal possession of forgery devices.

Wasltrom is the son of firefighter John Walstrom, a New York City hero who risked his life to rescue victims of the Sept. 11 terrorist attacks. John Walstrom died of an illness in 2013, the Post reports.
