Magna Hospitality Group

Magna Hospitality Group's network was breached on May 22, 2025, and its California filing says nothing about how, what data was taken, or how many people it touched. Qilin claimed the attack in October of 2025, saying it exfiltrated roughly 385 GB. The ransomware group published its account a full year before Magna's notice did. When the extortionist is the first to speak, both detection and disclosure run on the attacker's schedule.
