Disclosure context

About Interlock

Interlock is a recently emerged ransomware group that began operations in October 2024, primarily motivated by financial gain through extortion activities targeting organizations across multiple sectors. The group's country of origin and potential affiliations remain unclear given their recent emergence, with insufficient public documentation to determine whether they operate as an independent entity or under a Ransomware-as-a-Service model. Limited public information exists regarding their specific attack methodologies, initial access vectors, or encryption techniques, as major cybersecurity firms and law enforcement agencies have not yet published comprehensive technical analyses of their operations. Since beginning operations, Interlock has reportedly compromised approximately 100 victims, with their targeting primarily focused on organizations in English-speaking countries including the United States, Canada, United Kingdom, and Australia, as well as Italy, while demonstrating a preference for attacking education, manufacturing, healthcare, and public sector entities. The group remains active as of late 2024, though comprehensive threat intelligence profiles from established security research organizations have not yet been published due to the group's recent emergence in the threat landscape. The group has been linked to 109 public disclosures across our corpus. First observed on a leak site on October 13, 2024; most recent post May 11, 2026. The operation is currently active.

Attack summary

Severity: high — Data has been published (not merely threatened), and the exfiltrated data includes PII for both clients and employees at scale. CDI's client base spans 800 dealerships, meaning third-party client data exposure is significant. While not explicitly medical or government data, the confirmed exfiltration and publication of PII at this scale across a multi-client software provider warrants a high severity rating.

The Interlock ransomware group claims to have compromised Computing Dynamics Inc. and exfiltrated a large volume of confidential data including client, employee, and corporate records containing names, phone numbers, addresses, and other personal information. The disclosure status is 'data_published', indicating the stolen data has been released.
