Inotiv Reports Massive Data Breach Impacting Thousands

**Inotiv Hit by Ransomware Attack, Exposing Sensitive Data of Nearly 10,000 Individuals**

Inotiv, a leading research organization, disclosed a ransomware attack that compromised the personal information of 9,542 individuals. The breach, which involved unauthorized access to the company’s systems, exposed highly sensitive data, including names, addresses, Social Security numbers, and financial and medical records.

The attack underscores the growing threat of ransomware, particularly against organizations handling confidential information. Cybercriminals successfully infiltrated Inotiv’s infrastructure, demonstrating that even well-established entities remain vulnerable to sophisticated cyber threats. The stolen data poses significant risks, including identity theft and financial fraud, with potential long-term consequences for affected individuals.

In response, Inotiv launched an investigation in collaboration with cybersecurity experts to assess the full extent of the breach and prevent future incidents. Affected individuals are being notified, and mitigation efforts are underway to address the fallout.

This incident reflects a broader trend of ransomware attacks targeting sectors with sensitive data, highlighting the need for enhanced cybersecurity measures. While Inotiv works to strengthen its defenses, the breach serves as a reminder of the persistent and evolving nature of cyber threats.
