Inotiv Under Siege: Ransomware Attack Encrypts Biomedical Research Systems
Inotiv, a U.S.-based company headquartered in West Lafayette, Indiana, has disclosed a serious cybersecurity incident in a filing with the U.S. Securities and Exchange Commission. On August 8, 2025, the organization detected unauthorized access to its systems. According to preliminary findings, an unidentified attacker infiltrated its infrastructure and encrypted portions of corporate resources.
Inotiv specializes in providing comprehensive solutions for biomedical research and preclinical development. Its portfolio includes contract research, drug testing, laboratory services, and the supply of laboratory animal models. The company’s clientele spans pharmaceutical corporations, biotechnology startups, and government agencies seeking support in evaluating the safety and efficacy of emerging medical treatments.
Upon detecting signs of encryption, the company immediately restricted access to its infrastructure, engaged external cybersecurity experts, and notified law enforcement authorities. A large-scale investigation is now underway to assess the scope and consequences of the intrusion.
The incident disrupted several services and affected internal data repositories as well as certain business applications. Temporary restrictions on network access forced the company to shift some processes to offline workflows under its business continuity strategy. However, a timeline for full restoration of operations has yet to be determined.
Leadership emphasized that the investigation remains ongoing and the full extent of the breach is still uncertain. It is possible that the consequences will affect not only operational activities but also financial performance, including revenue, profit, and cash flow. Beyond economic damage, relationships with partners and clients, along with corporate reputation, may also be at risk. The company has not ruled out potential litigation or heightened regulatory scrutiny.
The official statement underscores that assessments of the incident may change as new information emerges. At present, it remains unclear whether the breach will lead to significant alterations in Inotiv’s financial position.
