lumiplan.com Listed by Cactus Ransomware Group

On October 18, 2024, French software company Lumiplan appeared on the leak site operated by the Cactus ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the company, which develops real-time information platforms used for citizen communication, mobility, and mountain tourist-site revitalization. The number of people whose data may be exposed remains unknown, and the exact contents of the stolen files have not been detailed in the public disclosure.

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

Details from the Cactus Listing

The primary disclosure on the Cactus leak site states that Lumiplan suffered a ransomware incident and that attackers successfully exfiltrated internal files. The listing includes basic corporate information such as the company’s reported $49.2 million revenue, its headquarters address in Saint-Herblain, France, and contact phone number. No specific volume of records or list of data types is provided; the disclosure simply states that internal files were taken. The leak site does not publish a sample of the stolen data, nor does it specify a ransom demand or payment deadline in the currently visible post.

Why This Matters for You and Your Family

When a company that operates public information screens and digital platforms is breached, the ripple effects often reach ordinary citizens. Lumiplan’s systems handle real-time data used in public spaces, transportation, and tourism. If employee, partner, or customer records were inside the exfiltrated files, your personal details could now sit on a criminal server. Even when exact record counts are unknown, the exposure of internal files in a ransomware event frequently includes contracts, employee directories, customer databases, or configuration data that can be repurposed for identity theft or targeted scams against families who interact with the affected systems.

The Doxxing and Identity-Chain Risks

Stolen internal files commonly contain email addresses, usernames, phone numbers, and project details that attackers chain together with data from other breaches. A single leaked work email can link your professional identity to personal accounts, gaming handles, or family member profiles. These identity chains accelerate doxxing: once criminals map one credential to your home address or children’s information, they can pursue account takeovers, SIM-swapping, or extortion. Credential leaks of this nature frequently cascade into gaming account compromises, especially when parents reuse work-related passwords for family or children’s profiles on popular platforms.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
