LGM Listed by termite Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On April 29, 2025, the organisation LGM was listed by the ransomware group known as termite. Public reporting indicates that internal files were exfiltrated during a ransomware attack, though the number of people affected remains unknown and many operational details have not been disclosed.

The listing itself is a claim by the group rather than an independently verified confirmation of every asserted detail. For clients, partners and staff connected to LGM, the incident raises practical questions about what information may have left the organisation’s systems and what steps can reduce residual risk.

What happened

According to the available record, LGM was named on a leak site associated with the termite ransomware group on or around April 29, 2025. The reported summary states that internal files were exfiltrated in the course of a ransomware attack. No public figure has been given for the volume of data taken, the precise date the intrusion began, or the technical method used to gain access. The number of individuals whose information may be involved is listed as unknown.

Ransomware incidents of this type typically involve unauthorised access followed by both encryption of systems and theft of files, with the threat of publication used as leverage. In this case, only the fact of the listing and the description of internal-file exfiltration have been placed in the public record. Whether any ransom was demanded, paid or refused, and whether the group has released any sample files, has not been confirmed in the facts available.

The group behind it: termite

Termite is a ransomware operation that, like other groups in this category, claims to encrypt victim networks and exfiltrate data before posting organisations on dedicated leak sites. Publicly documented patterns for such actors include double-extortion tactics: systems are locked, copies of files are removed, and the threat of full publication is used to pressure payment. Groups of this kind often advertise themselves through dark-web portals and sometimes provide limited “proof” samples to demonstrate possession of data.

No specific statements attributed to termite about LGM beyond the act of listing the organisation appear in the provided record. Therefore the listing must be treated as the group’s claim. Established public knowledge of ransomware crews shows they frequently target mid-sized enterprises and industrial-service firms, but any assertion that termite has released LGM material, named particular file types, or set a deadline remains unconfirmed by the facts given here.

LGM and its sector

LGM is described as a subsidiary of Groupe LGM. Its stated activity is to accompany clients in improving performance across design, production, operation and maintenance. Organisations of this profile typically operate in industrial engineering, manufacturing support, asset management or related technical consulting. They routinely handle project documentation, process specifications, supplier and client correspondence, operational schedules and, in many cases, personal data of employees and contractors.

A breach at such a firm is consequential because the data often spans multiple client organisations and can include proprietary technical information as well as contact and contractual records. Even when the exact contents remain undisclosed, the sector’s reliance on shared engineering files and long-term client relationships means that unauthorised access can affect parties well beyond LGM’s own workforce.

What data was at risk

The facts name the exposed material simply as “internal files exfiltrated in ransomware attack.” No further breakdown—such as employee records, client lists, financial documents or technical drawings—has been provided. Because the precise inventory is unconfirmed, it is not possible to state which categories of information left the organisation.

Firms that support design, production, exploitation and maintenance commonly hold engineering drawings, process parameters, maintenance logs, supplier contracts, employee directories and client project files. Any or none of these may have been among the internal files taken; public detail does not allow confirmation. Readers should therefore treat the exposure as involving internal corporate material of undetermined sensitivity rather than any specific named dataset.

What's at stake

For individuals whose details may appear in the exfiltrated files, the concrete risks include targeted phishing that references real project names or colleagues, identity-related fraud if personal identifiers were present, and unsolicited contact that appears legitimate because it draws on genuine internal context. For LGM itself, the stakes include potential disruption of client work, contractual obligations to notify partners, and the longer-term cost of forensic investigation and system hardening.

Because the scale remains unknown, the practical impact cannot yet be quantified. The absence of a confirmed headcount or file inventory means that both the organisation and any affected parties must proceed on the basis of precaution rather than precise measurement. Secondary risks—such as further distribution of the files by third parties who obtain them from a leak site—also exist once data has left controlled systems, though no public evidence of such redistribution has been recorded for this incident.

Were you affected?

If you are a current or former employee, contractor or client of LGM, treat the possibility of exposure seriously until more information emerges. Practical first steps include:

• Monitor financial and email accounts for unusual activity and enable multi-factor authentication where available.
• Be cautious of unsolicited messages that reference LGM projects, colleagues or technical details; verify any request through a known separate channel.
• Change passwords for accounts that may have been used in connection with LGM systems, especially if the same credentials were reused elsewhere.
• Request a free exposure scan of your email address against known breach datasets to check whether your information has already appeared in public or criminal collections.
• Retain any official notification you receive from LGM or its parent group and follow the specific guidance it contains.

Public detail on this incident remains limited. Further verified information, if released by LGM or independent investigators, should be used to refine these steps. Until then, measured vigilance is the most useful response.
