About this actor
A loosely-attributed actor claiming responsibility for a 2023 release of US Postal Service Informed Delivery scans and address data. Multiple low-confidence claims surfaced on BreachForums; the Postal Inspection Service has not publicly attributed the breach. Included for tracking the data-leak hacktivism trend rather than as a confirmed group.
