3 articles · Updated · CNBC · Aug 14
Summary
More than 471 million breach notices were issued in the first half of 2026, already far above the 297.5 million recorded in all of 2025, according to the Identity Theft Resource Center.
Canvas alone accounted for 275 million notices, while the number of reported incidents rose to 1,803 from 1,732 a year earlier, putting 2026 on track to exceed last year's 3,321 breaches.
AI is accelerating the trend: IBM found one in four breaches between March 2025 and February 2026 was AI-enabled, up 56% from a year earlier.
Malicious insider events climbed to 21 in six months from three in all of 2025, driven in part by laid-off employees and by North Korean operatives posing as remote IT workers with stolen identities and deepfakes.
Only 24% of consumer notices in H1 included breach details, down from 93% in 2021, leaving victims with uneven disclosure as experts urge credit monitoring, fraud alerts and credit freezes.
