Medici Group Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Medici Group was listed by thegentlemen ransomware group on April 04, 2026 after internal files were exfiltrated in a ransomware attack, with the number of people affected not yet disclosed. Individuals are advised to check any notices from the organisation and monitor their accounts for unusual activity.
What happened
The only confirmed information is the public listing itself. Thegentlemen claims to have exfiltrated internal files from Medici Group in the course of a ransomware operation. No date of the intrusion, no count of records, and no description of the specific files have been disclosed. The organization has not issued a public statement confirming or denying the claim.
Who is thegentlemen?
Thegentlemen is a ransomware group that maintains a leak site where it lists organizations it claims to have compromised. Such groups typically encrypt systems and threaten to publish stolen data unless a ransom is paid. The listing of Medici Group follows the pattern the group has used with other claimed victims; at this stage it remains an unverified assertion by the group.
About Medici Group
Medici Group operates themedicigroup.com and offers a subscription-based platform aimed at improving organizational performance. Its MOVES methodology is marketed to government bodies and other enterprises, combining research-derived practices with tools such as an AI coach and performance-engineering sessions. Because the firm works directly with public-sector clients, any exposure of its internal records could touch materials related to those engagements.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of data types has been published. Organizations of this kind routinely hold client contracts, project documentation, employee records, and communications with government customers. The precise categories and volume of material remain unconfirmed.
Why it matters
Even without a confirmed record count, the presence of government clients means any released files could contain details about public programs or personnel. Individuals whose information appears in those files face the ordinary downstream risks associated with leaked internal documents: targeted phishing, misuse of contact details, or reputational exposure. For the organization, the incident adds to the operational and regulatory burden that follows any ransomware claim.
What to do if you're exposed
Monitor email and financial accounts for unusual activity and enable multi-factor authentication where available. Review any recent correspondence from Medici Group or its clients for official guidance. Individuals can also run a free exposure scan of their email address against known breach data to check whether their information has appeared in previously published sets.

Publicly posted by thegentlemen — unverified claim, pending independent verification
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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
