In May 2026, threat actor SHADOW-AETHER-015 compromised Instructure's Canvas LMS backend, exposing sensitive data from 8,809 global educational institutions. The breach, likely facilitated via API exploitation or third-party integration compromise, exposed PII and private communications, creating significant risk for highly targeted follow-on spear-phishing and credential abuse campaigns.
The threat group ShinyHunters compromised Instructure's Canvas learning management system, likely via voice phishing (vishing) targeting their interconnected Salesforce environment. The breach resulted in the theft of 3.65 TB of sensitive data affecting 275 million users, which the actors are now leveraging in an active extortion campaign and which poses a severe downstream phishing risk.
