Incident Details
A man from Ayer was formally accused today and has agreed to admit guilt in relation to a cyberattack in June 2023 that was aimed at the computer network of a public high school in Essex County. The individual, Conor LaHiff, aged 30, was charged in legal documentation with one instance of causing unauthorized harm to safeguarded computers. Records from the court indicate that LaHiff had been employed as a manager for desktop and network operations at a public high school in Essex County until his termination in June 2023. Following his dismissal, LaHiff reportedly utilized his administrative rights to disable and remove thousands of Apple IDs from the school's Apple School Manager platform – software utilized for overseeing the information technology resources of students, faculty, and staff. Additionally, LaHiff purportedly deactivated over 1,400 other Apple accounts and various IT administrative accounts and disrupted the school's internal phone system, resulting in the unavailability of phone services for about a day. The offense of unauthorized harm to safeguarded computers carries a potential punishment of up to 10 years of imprisonment, a maximum of three years of supervised release, and a financial penalty of $250,000 or double the total gain or loss.
