Federal Cyberattack Case Lands Former Essex County IT Manager Behind Bars

BOSTON, MA – In a high-profile case, Conor LaHiff, 30, of Ayer, Massachusetts, was sentenced to one month in prison along with three years of supervised release, with the first 12 months to be served in home confinement, for committing a devastating cyberattack against his former employer, an Essex County public high school.

As previously reported, LaHiff was employed as a desktop and network manager at the Essex County public high school until he was terminated in June 2023. However, things took a dark turn as he used his administrative privileges to wreak havoc on the school’s computer network, deactivating thousands of Apple IDs from the school’s Apple School Manager account and disabling the school’s private branch phone system, leaving the school without phone service for approximately 18 hours.

According to Acting U.S. Attorney Joshua S. Levy, LaHiff’s actions were a clear indication of his intent to retaliate against his former employer through costly and dangerous cyberattacks. Levy emphasized that individuals who exploit their specialized knowledge to commit such crimes will be held accountable.

LaHiff’s short-sighted scheme has brought severe consequences, including a $34,110 restitution order, which he is required to pay. The FBI, assisted by the Massachusetts State Police and the Haverhill Police Department, played a significant role in investigating and bringing LaHiff to justice.

Conor LaHiff, the defendant, pleaded guilty to one count of unauthorized damage to protected computers in December 2023. After his termination for the charged conduct, LaHiff had obtained a similar position at another public high school, further highlighting the severity of his actions.

LaHiff’s case serves as a warning to others who may consider similar schemes, as the FBI will relentlessly track down and bring to justice cybercriminals, regardless of their motivations for breaking the law. Jodi Cohen, Special Agent in Charge of the FBI Boston Division, emphasized that committing a cyber intrusion to settle a score with a former employer is a bad idea and can have devastating consequences.

The case was prosecuted by Assistant U.S. Attorney Mackenzie A. Queenin of the Securities, Financial & Cyber Fraud Unit. LaHiff’s sentencing brings closure to the Essex County public high school community, which suffered significant disruptions due to his actions.

The exact date of the cyberattack was not specified in the source. However, it is mentioned that LaHiff was terminated in June 2023 and pleaded guilty in December 2023.
