The pharmaceutical and biotechnology company Inotiv Inc. is investigating a cyberattack that led to hackers encrypting the firm’s data, it said in a filing on Monday with the U.S. Securities and Exchange Commission.
The Aug. 8 attack disrupted access to certain data storage and business applications, according to Innotiv. The company said it is working to bring certain systems back online and has moved some operations to offline alternatives in order to maintain business continuity.
The company has restricted access to its systems, retained third-party experts and notified law enforcement, according to its SEC filing.
Innotiv reported that it was working diligently to restore normal operations but did not have a timeline for recovery. It also said it didn’t yet know whether the attack would have a material impact on its operations.
The hackers behind the Qilin ransomware have claimed credit for the attack, according to researchers at Huntress and Kroll.
Qilin claims to have 176 GB of data in the posting and provided nine images of documents it claims to have as proof of compromise, according to Max Rogers, senior director, security operations center at Huntress.
The researchers cannot independently confirm the authenticity of the documents. Huntress was not involved in any investigation or incident response related to the attack.
The group previously claimed credit for a massive attack on the media company Lee Enterprises that disrupted newspaper operations and cost $2 million in restoration and recovery expenses.
