fdcbuilding Listed by cuba Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The fdcbuilding Listed by cuba Ransomware Group (reported January 13, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
On January 13, 2022, the organization fdcbuilding appeared on a leak site operated by the Cuba ransomware group. The listing indicated that internal files had been taken during a ransomware incident, though the number of people affected and the precise contents of any data remain unknown.
The event is one of many in which organizations are publicly listed by ransomware operators after data is removed from their systems. Such listings are presented by the operators as evidence of successful exfiltration, but independent confirmation of the claims is not available from public records.
What happened
The only confirmed public information is that fdcbuilding was added to the Cuba ransomware group’s leak site on January 13, 2022. The group stated that internal files had been removed from the organization’s systems. No further details on the method of access, the volume of data, or the timeline of the intrusion have been disclosed.
The number of individuals whose information may be involved is not reported. The organization has not issued a public statement confirming or denying the claims in available records.
Who is cuba?
Cuba is a ransomware operation that has been active since at least 2019. The group is known for deploying ransomware that both encrypts systems and copies data for later use in extortion. It typically targets mid-sized organizations across multiple sectors rather than focusing on a single industry.
Public reporting has documented the group’s use of double-extortion tactics, in which operators threaten to publish stolen files if a ransom demand is not met. The Cuba group maintains a leak site where it lists victims and, in some cases, posts samples of claimed data. Attribution of any specific listing rests on the group’s own statements unless independently verified.
About fdcbuilding
Fdcbuilding operates in the construction and building-services sector. Organizations of this type routinely maintain records related to projects, suppliers, employees, and clients. These records can include contact information, financial details, and operational documents that support ongoing work.
A ransomware incident involving data removal at such an organization can affect both internal operations and any third parties whose information is held in project or administrative files. The exact scope of records held by fdcbuilding has not been made public.
What was likely exposed
The only data type named in connection with the listing is internal files removed during the ransomware attack. No inventory of specific file categories, record counts, or data fields has been released.
Organizations in the building sector commonly store employee records, vendor contracts, project documentation, and client correspondence. Whether any of these categories were among the files referenced in the Cuba listing is unconfirmed.
Why it matters
When internal files are removed from a construction-related organization, the material can include details that identify individuals or reveal business relationships. Exposure of such information can lead to targeted follow-on activity such as phishing or misuse of contact data.
For the organization, the incident adds the task of assessing what was taken and responding to any resulting regulatory or contractual obligations. The absence of Reported Details on the data limits the ability of affected parties to evaluate their specific exposure at this time.
If your data was in this claimed breach
Individuals who believe their information may have been held by fdcbuilding should monitor accounts for unusual activity and consider placing fraud alerts with credit agencies. Changing passwords for any services associated with the organization is a standard precaution.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
