Report Shows Surge in Malicious Insider Incidents; Mega Data Breaches
There has been a general trend of increasing data breaches over the past decade, with this year on track to set a new record. According to the H1 2026 Data Breach Report from the Identity Theft Resource Center (ITRC), there have been at least 1,803 data compromises in H1 2026, which will give an annual total of more than 3,600 data compromises if they continue to occur at a similar rate as the first half of the year. Across those data compromises, there have been 1,394 confirmed data breaches (excluding leaks, exposures, and unknown incidents), accounting for 77% of total events.

As ITRC explains in the report, part of the reason is the return of mega data breaches, the biggest of which involved the Instructure Holdings’ Canvas platform, which...
