A massive cybersecurity week. On this episode of Cybersecurity Today, David Shipley breaks down the reported breach of Instructure's Canvas learning platform, where attacks linked to the ShinyHunters extortion group may have exposed data tied to up to 275 million user accounts across more than 9,000 educational institutions. The incident disrupted access, delayed exams, and forced Instructure to disable its "Free for Teacher" program after attackers allegedly used it to post extortion messages. Also in this episode: the Gentlemen ransomware group suffers a major internal leak, exposing affiliate chats, tooling, victim data, and operational details — a rare look inside a live ransomware operation. Then, General Motors agrees to a $12.75 million California settlement over allegations involving OnStar-linked driver data collection and sharing, raising fresh questions about privacy in connected vehicles. And finally: security researchers report what appears to be the first documented AI-assisted operational technology (OT) cyberattack attempt targeting a water utility in Monterrey, Mexico. The attempt failed to reach industrial control systems, but combined with confirmed attacks on water infrastructure in Poland, it signals a worrying shift in critical infrastructure threats. If you work in cybersecurity, IT, infrastructure, education, or privacy, this episode matters.
