Mega Breaches Drive Record 2026 Notices

Data-breach victim notices reached an estimated 471.

2 million in the first half of 2026, already exceeding the 297.5 million notices recorded during all of 2025. A major compromise involving Instructure's Canvas platform accounted for roughly 275 million notices, while supply-chain incidents, malicious insiders, vulnerabilities, and AI-assisted activity added to the exposure. The scale of the notices increases risks of identity theft and account takeover, but limited disclosure of attack details makes the underlying causes difficult to assess consistently.
