Disclosure context

About LockBit

LockBit is a highly prolific ransomware group that emerged in October 2020 and has become one of the most active ransomware operations globally, with over 3,500 documented victims and a primary motivation of financial gain through extortion. The group is suspected to originate from Russia and operates as a Ransomware-as-a-Service (RaaS) model, recruiting affiliates to conduct attacks while providing them with ransomware tools, infrastructure, and support. LockBit primarily gains initial access through exploiting vulnerabilities in public-facing applications, credential stuffing attacks, and phishing campaigns, employing double extortion tactics where they steal sensitive data before encrypting systems and threatening to leak the information if ransom demands are not met. The group has demonstrated significant technical sophistication, developing multiple variants including LockBit 3.0 (also known as LockBit Black), and has been particularly active in targeting business services, manufacturing, technology, and healthcare sectors across the United States, France, Germany, United Kingdom, and Italy. Despite ongoing law enforcement efforts and international cooperation to disrupt their operations, including seizures of infrastructure and arrests of affiliates, LockBit has shown resilience and adaptability, continuing to operate and evolve their tactics while maintaining their position as one of the most dominant ransomware threats in the cybercriminal landscape. The group has been linked to 3,536 public disclosures across our corpus. First observed on a leak site on October 21, 2020; most recent post March 30, 2026. The operation is currently active.

Attack summary

Severity: critical — DM² is ITAR-registered (defense-related export-controlled technical data), ISO 13485-certified (medical devices), and AS9100-certified (aerospace). Exfiltration of data from a company operating in these regulated sectors — especially one handling flight-critical and medical components — constitutes exposure of potentially ITAR-controlled, medical, and aerospace-sensitive data, meeting the critical threshold.

LockBit claims to have attacked DM² and has published data (disclosed status: data_published), indicating exfiltration of company data has occurred. No ransom amount or specific data volume was stated in the leak post.
