Pharma firm Inotiv discloses data breach after ransomware attack

In August 2025, Indiana-based contract research organization Inotiv suffered a ransomware attack that disrupted systems and led to the theft of data; the company has restored access and is notifying 9,542 individuals. The Qilin ransomware group claimed responsibility, posted leaked samples, and asserted exfiltration of roughly 162,000 files (176 GB), though Inotiv has not publicly confirmed specific data types or formally attributed the breach to Qilin.
