First Defense Fire Protection Listed by anubis Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to pressure organisations by exfiltrating internal files and listing victims on dark-web leak sites, turning proprietary documents into leverage. In this climate, even specialised service firms that hold building plans and safety data have become targets. On 25 February 2025, First Defense Fire Protection appeared on a listing attributed to the anubis ransomware group, which claimed to have taken internal files that include blueprints for casinos, airports and hundreds of other companies.

Public detail remains limited: the number of people affected is unknown, and independent confirmation of the full scope has not been released. The listing itself is a claim by the group rather than a verified disclosure. Still, the nature of the material allegedly involved makes the incident consequential for the firm, its clients and anyone whose personal or project data may have been stored alongside those files.

What happened

According to the reported summary, First Defense Fire Protection was listed by the anubis ransomware group on 25 February 2025. The group claims that internal files were exfiltrated during a ransomware attack and that the material includes leaked blueprints for casinos, airports and hundreds of other companies. No further public detail has been provided on the precise date of intrusion, the initial access method, the volume of data taken, or whether encryption was also deployed. The number of individuals affected is listed as unknown. Because the information originates from a threat-actor leak-site claim, it should be treated as unverified until the organisation or independent investigators state it.

Who is anubis?

Anubis is a ransomware operation that has appeared in public reporting as a double-extortion group: operators typically encrypt systems while also stealing data, then threaten to publish the stolen material if a ransom is not paid. Like many such groups, anubis maintains a leak site where it posts victim names and sample files to increase pressure. Public accounts of its activity describe opportunistic targeting across multiple sectors rather than a single industry focus, with listings used both as proof of compromise and as a marketing tool for the group’s services. In this case, the group claims First Defense Fire Protection as a victim and asserts that internal files containing blueprints were taken; those assertions have not been independently corroborated in the available facts.

About First Defense Fire Protection

First Defense Fire Protection operates in the fire-protection and life-safety sector. Firms of this type design, install and maintain fire-suppression systems, alarms, sprinklers and related infrastructure for commercial, industrial and public buildings. Because their work requires detailed knowledge of building layouts, occupancy, and safety systems, they routinely hold architectural drawings, engineering plans, system schematics and project documentation for clients that can include casinos, airports, hotels, offices and other large facilities. Such material is sensitive: it can reveal structural details, access routes, fire-control locations and other information that is not intended for public release. A breach at a company holding these records therefore raises concerns that extend beyond the firm itself to the many organisations whose facilities it has served.

What data was at risk

The available facts state that internal files were exfiltrated in a ransomware attack and that the group claims the material includes blueprints for casinos, airports and hundreds of other companies. Exact data types beyond that description, file counts, and whether personal employee or customer records were also present have not been disclosed. Organisations in the fire-protection sector typically retain project files, client contracts, engineering drawings, system configurations, and sometimes employee or contractor contact information. Because the precise contents remain unconfirmed, it is not possible to state which specific categories of personal or proprietary data were exposed. Readers should treat any claim about particular documents as originating from the threat actor until verified.

Why it matters

If the claimed blueprints and related internal files are authentic, the exposure could give unauthorised parties insight into the physical layouts and fire-safety systems of numerous high-profile and high-occupancy sites. That information can be useful for competitive intelligence, social-engineering attempts against the affected companies, or, in a worst case, physical-security planning. For First Defense Fire Protection itself, the incident carries operational, contractual and reputational consequences: clients may demand assurances, regulators or insurers may inquire, and the firm may face remediation and notification costs. For individuals whose contact details, employment records or project-related personal data happened to reside in the same systems, the practical risks include phishing, identity-related fraud and unwanted contact. Because the number of people affected is unknown and the full inventory of files is unconfirmed, the scale of personal impact cannot yet be quantified; the prudent assumption is that anyone who has worked with or for the company should remain alert.

What to do if you're exposed

If you have a past or present relationship with First Defense Fire Protection—as an employee, contractor or client—monitor accounts and communications for unusual activity. Enable multi-factor authentication where available, treat unexpected requests for credentials or payments with caution, and consider placing a fraud alert with credit bureaus if you believe personal identifiers may have been involved. Keep records of any suspicious contact. You can also run a free exposure scan of your email address to check whether it has already appeared in known breach data sets; such a scan is a practical first step while waiting for any formal notification from the organisation. Official guidance from the company, if issued, should take precedence over third-party claims.
