Top Data Breaches of January 2026 (So Far) – Updated Daily

Record-Breaking Start to 2026

It’s only January 23, 2026, but the year has already shattered records with 29 organizations breached in 22 days, compromising over 5.5 million records. Industries hit hardest include healthcare, manufacturing, finance, telecom, and even government agencies like ICE and Border Patrol.

Common failure points across these incidents: lack of multi-factor authentication (MFA), no endpoint detection and response (EDR), and inadequate vendor security audits.
