cgm.com Listed by lockbit2 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The cgm.com Listed by lockbit2 Ransomware Group (reported December 25, 2021) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
The incident came to light when cgm.com appeared on the lockbit2 leak site. According to the listing, the group states that it exfiltrated internal files during a ransomware operation. No further details on the timing of the intrusion, the volume of data involved, or the method of access have been made public. The organization has not issued a separate confirmation of the claims in the available facts.
Who is lockbit2?
Lockbit2 is a ransomware-as-a-service operation that has been publicly documented since at least 2019. The group typically supplies encryption tools to affiliate attackers in exchange for a share of ransom payments. Its documented tactics include encrypting victim systems and threatening to publish stolen data if payment demands are not met. The group has appeared in multiple prior incidents involving organizations across different sectors, though any specific claims it makes about individual victims on its leak site remain unverified until independently confirmed.
About cgm.com
cgm.com operates in the healthcare information technology sector, providing software and services used by medical practices, hospitals, and related organizations. Entities of this type routinely process and store records connected to patient care, administrative operations, and clinical workflows. A listing on a ransomware leak site therefore raises questions about the handling of data that supports essential healthcare functions, even when the exact scope of exposure is not yet established.
What was likely exposed
The facts state only that internal files were exfiltrated. No inventory of specific file types, record counts, or data categories has been released. Organizations in this sector commonly maintain internal documents that can include operational records, communications, and system configurations. Without additional disclosure, the precise nature of the material cannot be confirmed beyond the general description of internal files.
What's at stake
Individuals connected to the organization may face risks if personal or administrative information later surfaces, though the scale of any such exposure is unknown. For the organization itself, the incident can lead to operational disruption, costs associated with investigation and recovery, and potential regulatory scrutiny common to healthcare-related entities. The absence of Reported Details on affected individuals limits the ability to assess concrete downstream effects at this stage.
What to do if you're exposed
Monitor official statements from cgm.com for any updates on the incident. Review account statements and correspondence for unusual activity. Enable multi-factor authentication on accounts that may be linked to the organization. Individuals can also run a free exposure scan of their email address against known breach data to check for appearances in previously reported incidents.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
