Carhartt suffered a data breach affecting approximately 12.9 million individuals — roughly half the 25 million claimed by hacking group ShinyHunters, which had padded the dataset with millions of lines of synthetic data. Troy Hunt of Have I Been Pwned uncovered the inflation through careful analysis, using tools to identify fake email domains, implausible demographics, and other anomalies before arriving at the genuine figure. The real breach exposed names, email addresses, phone numbers, and physical addresses, with Carhartt yet to publicly comment on the incident.
