The FBI issued a public service announcement warning students and educational institutions about a nationwide cyberattack on an unnamed learning management system claimed by the ShinyHunters group; the platform was restored but personal data may have been exfiltrated. The advisory outlines ShinyHunters' history of large-scale breaches, extortion, use of a Tor-hosted leak site, and abusive tactics (threats, swatting), and urges victims to avoid paying ransoms, verify communications, reset credentials, preserve evidence, and report incidents to the FBI/IC3 — highlighting growing cyber risks to the education sector.
