\n A cyberattack shut down an education platform used by universities and K-12 schools across the US Thursday, depriving students and teachers of essential classroom materials \u2014 at a time when many are taking or preparing for final exams.\n <\/p>\n

\n Canvas, a popular, cloud-based digital hub for classrooms, has more than 30 million active users globally, with more than 8,000 institutions as customers, parent company Instructure<\/a> \ufeffsays on its website.\n <\/p>\n

\n Large public school systems and top universities like Columbia, Princeton, Harvard and Georgetown reported a ransom note signed by a hacking group had appeared on the homepage of their schools\u2019 Canvas sites Thursday.\n <\/p>\n

\n The hack came after the group believed to be behind it warned Instructure in a ransom note to \u201cpay or leak,\u201d saying it had accessed data from millions of users, including students, teachers, and staff.\n <\/p>\n

\n The FBI has mobilized resources in multiple states to assist victims of the hack, a source familiar with the matter told CNN.\n <\/p>\n

\n The FBI confirmed Friday the agency was aware of the platform service disruption and advised concerned students and faculty to wait for official guidance from their school \u201cregarding the scope of the incident and the nature of any affected data.\u201d\n <\/p>\n

\n The agency warned impacted individuals to be wary of potential scammers claiming to have their data.\n <\/p>\n

\n \u201cBy receiving a message, that does not necessarily mean your personal information has been compromised,\u201d the FBI statement said, explaining scammers often exaggerate or lie about their access to data in order to get money from victims.\n <\/p>\n

\n Instructure said Friday morning Canvas was \u201cfully back online and available for use.\u201d Multiple universities and school districts throughout the country reported their Canvas pages were back up and running on Friday, though some schools had already extended deadlines and changed finals schedules because of the hack.\n <\/p>\n

\n Here\u2019s what we know.\n <\/p>\n

\n A University of Washington student who tried to log into Canvas around noon Thursday was greeted by a message from the hacking group ShinyHunters, which claimed to have \u201cbreached\u201d the platform\u2019s parent company, according to a screenshot obtained by CNN.\n <\/p>\n

\n The note, reported by different student news outlets, demanded ransoms to prevent data leaks from the platform.\n <\/p>\n

\n A student at the University of Pennsylvania said he was logged out of his Canvas account while studying for finals. Professors had to scramble to send class materials in other ways, the student said.\n <\/p>\n

\n Universities across the country, including Columbia University, Rutgers, Princeton, Kent State, Harvard and Georgetown issued statements alerting students to the hack impacting institutions nationwide. School districts in California, Florida, Georgia, Oklahoma, Oregon, Nevada, North Carolina, Tennessee, Utah, Virginia, Texas <\/strong>and Wisconsin also reported being affected.\n <\/p>\n

\n This was the second school data breach claimed by ShinyHunters this month. In Thursday\u2019s ransom note, the group claimed it had hacked Instructure \u201cagain\u201d and faulted the company\u2019s response to the previous attack: \u201cInstead of contacting us to resolve it they ignored us and did some \u2018security patches.\u2019\u201d\n <\/p>\n

\n On May 1, Instructure said it \u201cexperienced a cybersecurity incident perpetrated by a criminal threat actor.\u201d The company said the breach had been \u201ccontained\u201d the next day but usernames, email addresses, student ID numbers and communications from some institutions appeared to have been exposed.\n <\/p>\n

\n ShinyHunters claimed in a ransom note shared on May 3 by Ransomware.live<\/a>, which tracks ransomware attacks and groups, that it had breached 275 million individuals\u2019 data and had access to \u201cseveral billions of private messages,\u201d giving a May 6 deadline for Instructure to reach out.\n <\/p>\n

\n In a note Thursday, the hacking group gave a May 12 deadline for impacted schools \u201cto negotiate a settlement.\u201d\n <\/p>\n

\n During the Canvas interruption, Instructure said on Thursday it put the platform in \u201cmaintenance mode\u201d as it investigated the issue. Later that night, it announced Canvas was available again \u201cfor most users.\u201d\n <\/p>\n

\n On Friday morning, Instructure announced an \u201cunauthorized actor\u201d exploited an issue related to the company\u2019s Free-For-Teacher accounts.\n <\/p>\n

\n \u201cAs a result, we have made the difficult decision to temporarily shut down our Free-For-Teacher accounts. This gives us the confidence to restore access to Canvas, which is now fully back online and available for use,\u201d the company said in a statement.\n <\/p>\n

\n Cyberattacks on educational platforms are not new. Software provider Finalsite suffered a ransomware attack in July 2022. The websites of about 5,000 schools were impacted<\/a>.\n <\/p>\n

\n During the pandemic, ransomware attacks interrupted remote learning for a number of schools in the US, including an incident that forced Baltimore County Public Schools to temporarily close in November 2020.\n <\/p>\n

\n The risk for students and faculty impacted by the attack, retired FBI special agent Richard Kolko says, is they could be victims, \u201cnot only today, but later.\u201d\n <\/p>\n

\n \u201cYou need to follow up\u2026because they have this information on these students now and a couple (of) years from now, they may use some of that information to attack them,\u201d Kolko told CNN\u2019s Boris Sanchez.\n <\/p>\n

\n The FBI has advised anyone who may have been affected by Thursday\u2019s cyberattack to not engage with anyone who claims to have their data, including by responding to demands or sending payments.\n <\/p>\n

\n \u201cWe encourage individuals to be cautious of unsolicited emails, calls, or texts claiming to be from your school, the (learning management system) provider, or law enforcement and to verify the contact through known channels before responding,\u201d the statement added.\n <\/p>\n

\n Little is publicly known about the hacking group that claimed responsibility for the Canvas outage, but cybersecurity researchers and federal authorities have linked the ShinyHunters name to several instances of high-profile data theft.\n <\/p>\n

\n The group claimed responsibility for hacking Ticketmaster and attempting to sell user data on the dark web in 2024, CNN previously reported<\/a>.\n <\/p>\n

\n Earlier this year, Mandiant, a cyber-intelligence firm owned by Google, reported<\/a> an increase in activity consistent with prior \u201cShinyHunters-branded extortion operations,\u201d saying the attackers use sophisticated voice phishing and fake, company-branded login pages to harvest employee credentials before stealing sensitive data from cloud-based platforms for ransom.\n <\/p>\n

\n In 2024, the US Department of Justice announced<\/a> the sentencing of a member of what prosecutors described as a notorious international hacking crew tied to the ShinyHunters name. Authorities said a user operating under that moniker posted stolen data from more than 60 companies for sale on dark web forums and at times threatened to leak sensitive files if victims did not pay.\n <\/p>\n

\n Court documents<\/a> tied to the member who was sentenced show US-based victims included technology, entertainment, communications, clothing and fitness companies, as well as a video game developer.\n <\/p>\n

\n How students and schools reacted
\n<\/h2>\n

\n Melanie Topchyan, a senior at the University of California, Riverside, said she missed a quiz Thursday because of the outage and worried about staying on track. She said she has a midterm next week for a demanding course and relies on Canvas to revisit lectures and notes.\n <\/p>\n

\n \u201cIt is a little bit of a freakout,\u201d she told CNN.\n <\/p>\n

\n Anish Garimidi, the University of Pennsylvania junior who was logged out of Canvas while trying to study, said he immediately felt a surge of anxiety.\n <\/p>\n

\n \u201cThe biggest cause of fear and anxiety in me is that I was deprived of significant resources to study and do the best,\u201d Garimidi told CNN.\n <\/p>\n

\n For many students, the disruption landed at the worst possible moment. Georgetown sophomore Minhal Nazeer had returned home to Kentucky because all of her remaining coursework was online through Canvas.\n <\/p>\n

\n But while some of her classmates were \u201cfreaking out,\u201d she saw an upside in the extra time they got after professors extended deadlines.\n <\/p>\n

\n \u201cI was already in a good spot to finish all my papers, so I\u2019m 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,\u201d she said.\n <\/p>\n

\n A Columbia University senior, who declined to be named, said the outage came at the \u201cmost inopportune time\u201d \u2014 just as many students were shifting from celebratory end\u2011of\u2011year events to serious exam preparation.\n <\/p>\n

\n That was particularly difficult, he said, for those who had only just begun compiling notes and study guides after having \u201cpushed off the thought of having to take exams in the following week.\u201d\n <\/p>\n

\n James Madison University moved some exams scheduled for Friday to Wednesday, the school said in an announcement<\/a>.\n <\/p>\n

\n The episode has underscored how deeply embedded Canvas has become in academic life at many institutions, not only as a submission portal but as a central communications tool.\n <\/p>\n

\n Kent State said Friday it is \u201cvery concerned\u201d about further disruptions as finals conclude.\n <\/p>\n

\n The university said the disruption also affected areas like tuition billing and financial aid. \u201cWe are currently in contingency planning with all of those areas,\u201d the statement said.\n <\/p>\n

\n At the Massachusetts Institute of Technology, Allison Park, a junior, said professors were scrambling to locate students\u2019 email addresses after losing access to Canvas\u2019 announcement feature.\n <\/p>\n

\n \u201cThe fact that this one website was the link between teaching staff and students outside of class \u2014 I didn\u2019t realize how big of a dependency we had on it until they were scrambling to find our emails,\u201d she said.\n <\/p>\n

\n Liane Xu, another MIT student, said her courses rely on Canvas to collect assignments and manage grading. Although some professors host course materials on separate websites, she said critical resources, lecture videos, notes and study documents are often stored within the platform.\n <\/p>\n

\n As the semester draws to a close, she said, access to those materials is essential.\n <\/p>\n

\n \u201cIt\u2019s unfortunate and we\u2019re sort of the victims of this,\u201d said the Columbia senior.\n <\/p>\n
