About the victim

AI dossier — public-source company profile

Groupe Caddac is a French construction materials group specialising in concrete in all its forms, including ready-mix concrete (BPE), precast elements (prémurs et prédalles), aggregates (granulats), powders, and related services. Founded in 1962, the group operates primarily in the Grand Ouest region of France and comprises several subsidiaries including Société de Préfabrication de Landaul (SPL), Cetra Granulats, Multimat, and ETRAMA. The group's country listing as Canada appears to be an operator error; the company is French.

Industry: Concrete & Precast Building Materials Manufacturing
Founded: 1962

Attack summary

Severity: medium — Disclosure status is data_published, implying exfiltration has occurred, but the leak post content is inaccessible and no specific data categories, volume, or proof files can be verified. The company is an industrial manufacturing group, so sensitive regulated data (e.g. medical, government) is not a primary concern, but business and employee data exposure elevates this above low.

The ransomware group 'thegentlemen' claims to have attacked Groupe Caddac and the disclosure status is listed as data_published, indicating data exfiltration has occurred. The leak post itself is inaccessible due to a bot-verification wall, so specific claims about data volumes or categories cannot be confirmed from the post.

Disclosure context

About thegentlemen

thegentlemen is a ransomware group that emerged in September 2025, operating with apparent financial motivations based on their broad targeting of commercial sectors. The group has documented 267 victims across multiple countries, with primary focus on the United States, Thailand, France, Brazil, and India. Their targeting strategy demonstrates a preference for high-value sectors including manufacturing, technology, healthcare, and financial services organizations. Given the group's recent emergence and limited public documentation from established threat intelligence sources such as CISA, FBI, or major security research firms, specific details regarding their country of origin, operational structure, attack methodologies, encryption techniques, and whether they employ ransomware-as-a-service models remain unclear. The relatively high victim count of 267 in a short operational timeframe since September 2025 suggests either an aggressive campaign pace or potential inflation of victim numbers through affiliate operations, though without corroborating intelligence reports, the group's exact operational capabilities and notable campaigns cannot be definitively established. Current intelligence indicates the group remains active as of late 2025, though comprehensive threat profiling requires additional validated reporting from authoritative cybersecurity sources. The group has been linked to 483 public disclosures across our corpus. First observed on a leak site on September 9, 2025; most recent post June 11, 2026. The operation is currently active.

If your organisation is affected

A listing by thegentlemen means Groupe Caddac appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Monitor for the data appearing on thegentlemen's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
