A cyber attack on Thursday hit several universities and schools in the US, causing chaos, confusion and major disruptions amid the high stakes end-of-year season.
The hacking group ShinyHunters reportedly claimed responsibility for the attack, which caused the academic software Canvas used by thousands of schools and universities to go offline.
By late Thursday, the company Instructure, which owns Canvas, posted an update on its website saying that Canvas was "available for most users".
The cyber attacks targeted universities and schools across the US, from California to New York.
Penn State University wrote in a message to students that "no one has access" to Canvas, adding that a "resolution" was unlikely to arrive "within the next 24 hours". The university cancelled some exams scheduled for Thursday and Friday.
