53.com Domain Breach Exposure Report

The domain 53.com has experienced a significant number of historical data breaches, totaling over 120,000 incidents, and a substantial volume of active infostealer logs, exceeding 11,000. The data indicates a concerning trend of compromise affecting both employees and clients, with peaks observed in late 2025 and early 2026. The primary malware families associated with these events are Redline, Rhadamanthys, and LummaC2, suggesting a focus on credential harvesting and information theft.
