Inotiv Hit by Ransomware Attack: U.S. Pharma Giant Disrupted
U.S.-based pharmaceutical research giant Inotiv has fallen victim to a ransomware attack. The incident occurred on August 8, 2025, with the culprits encrypting systems and data, causing significant disruption to operations. While the exact group behind the attack remains unknown, the Qilin ransomware gang has claimed responsibility.
Inotiv swiftly responded to the breach, launching an investigation with external cybersecurity experts and notifying law enforcement. The company is currently working to restore affected systems and has transitioned certain operations to offline alternatives to maintain business continuity.
The ransomware attack, which encrypted certain systems and data, has limited access to data and applications, disrupting day-to-day operations. Inotiv has not yet specified which systems or data were targeted, but the Qilin group alleges they stole around 176GB of data. Despite the claim, Inotiv has not confirmed the extent of data exfiltration.
Inotiv continues to work diligently to restore its systems and resume normal operations. The company has not yet identified the group responsible for the attack, nor has it confirmed the Qilin group's claim of data theft. As the investigation progresses, Inotiv remains committed to transparency and will provide updates as more information becomes available.
