Gitlabs: hemio.de, SOLEIL, Devlion Listed by fog Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 4 February 2025, the entities listed as Gitlabs: hemio.de, SOLEIL, Devlion appeared on the leak site operated by the fog ransomware group. Public reporting states that the group claims to have stolen internal data in a ransomware attack; the number of people affected remains unknown and further operational details have not been disclosed.

A listing of this kind signals that an organisation’s internal material may have left its control. For anyone who works with or relies on these GitLab-related services, the claim raises practical questions about what was taken and what residual risk remains.

What happened

According to available records, Gitlabs: hemio.de, SOLEIL, Devlion was listed on the fog ransomware leak site on or around 4 February 2025. The group asserts that it exfiltrated internal files during a ransomware attack. No independent confirmation of the intrusion method, the volume of data, the precise date of compromise, or any ransom demand has been made public. The count of individuals whose information may be involved is recorded as unknown. At present the incident rests on the group’s own claim that internal data was stolen.

Who is fog?

Fog is a ransomware operation that became active in the public eye in 2024. Like many contemporary groups, it typically follows a double-extortion model: encrypting systems while also copying data and threatening to publish it on a dedicated leak site if payment is not made. Fog has been observed targeting a range of organisations across different sectors, posting victim names and sample files to pressure negotiations. Its listings are claims made by the group itself; they do not automatically prove that every asserted detail is accurate or that the full dataset has been released. In this case, the only public assertion tied to Gitlabs: hemio.de, SOLEIL, Devlion is that internal files were taken.

Who is Gitlabs: hemio.de, SOLEIL, Devlion?

The designation “Gitlabs: hemio.de, SOLEIL, Devlion” points to one or more GitLab instances or related development environments associated with those names. GitLab platforms are widely used for source-code hosting, version control, continuous-integration pipelines, issue tracking and collaboration among software teams. Organisations that run such systems commonly store proprietary code, configuration files, credentials, project documentation, internal communications and sometimes customer or partner data. A breach involving these assets can therefore affect not only the operators but also developers, clients and any third parties whose material resides in the repositories. Public detail about the precise corporate structure or size of hemio.de, SOLEIL and Devlion is limited; what matters for risk assessment is the nature of the systems they appear to operate.

The information in question

The only data type named in public reporting is “internal files exfiltrated in a ransomware attack.” No inventory of specific file categories, record counts or sample contents has been released. Organisations that maintain GitLab environments typically hold source code, build scripts, access tokens, internal wikis, issue tickets and sometimes personally identifiable information belonging to employees or users. Because the exact contents remain unconfirmed, it is not possible to state which of these categories—if any—were among the material the group claims to possess. Readers should treat the exposure as limited to the group’s assertion of stolen internal files until further verified information appears.

The real-world impact

If internal files were in fact copied, several concrete risks follow. Source code or configuration data could be reused by others to identify vulnerabilities, clone proprietary logic or craft more targeted attacks against the same organisation or its customers. Credentials or tokens that may have been stored in repositories could enable further unauthorised access. Employees or contractors whose personal details appear in tickets or documentation face ordinary identity-related risks such as phishing or social-engineering attempts that reference the leaked material. For the organisation itself, the listing can disrupt development workflows, force credential rotation, require forensic review of repositories and create contractual or regulatory notification obligations depending on jurisdiction and the nature of any personal data involved. Because the scale and exact contents remain undisclosed, the full extent of these risks cannot yet be quantified.

Were you affected?

Anyone who has used accounts, repositories or services linked to hemio.de, SOLEIL or Devlion should treat the claim seriously until more information is available. Practical first steps include:

• Change passwords and revoke any personal access tokens or SSH keys associated with the affected GitLab instances.
• Enable multi-factor authentication where it is not already active.
• Review recent repository activity and access logs for unfamiliar commits or downloads.
• Monitor financial and email accounts for unusual activity that could stem from secondary use of leaked credentials.
• Run a free exposure scan of your email address against known breach data sets to see whether your information has already appeared in public dumps.

If you receive notification from the operators themselves, follow their guidance promptly. Public detail remains limited; continued monitoring of official statements from the organisations involved is the most reliable way to learn whether additional data types or affected individuals are later confirmed.
