A Massachusetts man who previously pleaded guilty to a cyberattack on PowerSchool, exposing data on tens of millions of students and teachers, was sentenced to four years in prison Tuesday — half the amount federal prosecutors sought in sentencing recommendations submitted to the court.

Matthew Lane, 20, stole data from PowerSchool belonging to nearly 70 million students and teachers, extorted the California-based company for a ransom, which it paid, causing the education software vendor more than $14 million in financial losses, according to prosecutors.

U.S. District Judge Margaret Guzman sentenced Lane to four years in prison, followed by three years of supervised release. Lane was also ordered to pay almost $14.1 million in restitution and a $25,000 fine for crimes involving the attack on PowerSchool and an undisclosed U.S. telecommunications company.

Federal prosecutors were seeking a sentence of eight years for Lane, arguing that the crimes he pleaded guilty to follow a series of cybercriminal activity dating back to 2021. “The government has serious concerns that Lane poses an ongoing threat to the community and remains in denial about the scope of his criminal activity,” prosecutors said in a sentencing memo filed Oct. 7 in the U.S. District Court for the District of Massachusetts. 

Prosecutors cited multiple examples of other cybercriminals who committed and were convicted of less serious crimes. In those cases, the lighter sentences cybercriminals received did not sufficiently deter them from reengaging in cybercrime upon their release from jail. Lane’s attack on PowerSchool put 10 million teachers and 60 million children, some as young as five years old, at risk of identity theft for the remainder of their lives, prosecutors said. 

The PowerSchool attack, which Lane committed in September 2024 by using a PowerSchool contractor’s credentials to gain unauthorized access, is reportedly the single largest breach of American schoolchildren’s data on record. Lane threatened to release the data in December 2024 if PowerSchool didn’t pay a ransom valued at nearly $2.9 million at the time.

Multiple school district customers of PowerSchool received follow-on extortion demands linked to the stolen same data, the company said in May. The downstream extortion attempts underscore how cybercriminals, affiliated or not, will continue to exploit sensitive data for financial gain.

Lane forfeited almost $161,000 traced to his crimes, but about $3 million in illicit proceeds remains unaccounted for, according to court documents. “The money he returned is barely one percent of the financial loss he caused,” prosecutors said in the court filing.

Lane is required to surrender to the Federal Bureau of Prisons by Dec. 1.
