New York (CNN) — Students attempting to access grades, study materials and quizzes were met instead with a message from a hacking group on Thursday.
Universities and school systems across the country, from local school districts to Georgetown University, reported a ransom note on the homepage of their schools鈥� Canvas sites. Canvas is a popular, cloud-based digital hub for classrooms.
Canvas , parent company Instructure 锘縮ays on its website, with more than 8,000 institutions as customers. Many of those students are in the middle of a busy Spring finals week.
Several universities across the country, including Columbia University, Rutgers, Princeton, Kent State, Harvard and Georgetown have issued statements alerting students to the hack impacting institutions nationwide. School districts in California, Florida, Georgia, Oklahoma, Oregon, Nevada, North Carolina, Tennessee, Utah and Virginia have also been affected.
This is the second data breach this month among schools and universities. Hacking group ShinyHunters claimed responsibility for both attacks. In the note, reported by different student news outlets, the group demanded ransoms to prevent further data leaks.
鈥淪hinyHunters has breached Instructure (again),鈥� read a warning on a University of Washington student鈥檚 account around noon PT, which was seen by CNN. 鈥淚nstead of contacting us to resolve it they ignored us and did some 鈥榮ecurity patches.鈥欌��
Instructure on its website that Canvas was 鈥渋n maintenance mode鈥� late Thursday afternoon, adding that it was investigating the issue.
On May 1, in a different attack, Instructure said it 鈥渆xperienced a cybersecurity incident perpetrated by a criminal threat actor鈥� but contained the situation the next day. But the company indicated that user names, email addresses and student ID numbers were breached.
鈥淚nstructure still has until EOD 12 May 2026 to contact us,鈥� Thursday鈥檚 note from the hacking group said.
CNN has reached out to Instructure for comment.
Some students in panic, others welcome deadline extensions
One student impacted by the hack said he was in a panic when he was logged out of his Canvas account while trying to study for finals at the University of Pennsylvania.
鈥淭he biggest cause of fear and anxiety in me is that I was deprived of significant resources to study and do the best,鈥� Anish Garimidi, a junior at the university, told CNN.
Garimidi called the incident 鈥渧ery troubling鈥� but said he is grateful his professors 鈥渨ere accommodating and sending materials through other means.鈥�
Another student, a sophomore at Georgetown University, said she returned home to Kentucky last week because all of her remaining projects were online via Canvas. But the digital hub went down Thursday afternoon for students at her school, who were instead greeted by a ransom note, Minhal Nazeer told CNN.
While a lot of students are 鈥渇reaking out,鈥� others 鈥� including her 鈥� are happy because the hack means students will have extended deadlines, Nazeer said.
鈥淚 was already in a good spot to finish all my papers, so I鈥檓 not too bothered by it, but I do see it is helping me a little, because I have gotten some extension. I just have more time to look over my things,鈥� she said.
Melanie Topchyan, a senior at the University of California, Riverside, said she missed a quiz on Thursday due to the hack, which she said is interrupting students鈥� schedules.
Topchyan has a midterm next week for a 鈥減retty difficult class,鈥� she said, and is worried because she needs access to Canvas to review lecture recordings and notes.
鈥淚t is a little bit of a freakout,鈥� she added.
