Breaking down the breach
The incident was reported on December 9, 2025, through the listing by coinbasecartel. The only confirmed detail is that internal files were allegedly exfiltrated during a ransomware attack. The number of people affected is listed as unknown. No description of the attack method, timeline of events, or confirmation of data publication has been released.
Who is coinbasecartel?
Coinbasecartel is a ransomware group that maintains a public leak site where it lists organisations it claims to have targeted. Such groups typically encrypt systems and exfiltrate data, then use the threat of publication to pressure victims. Their listings represent claims made by the group rather than independently verified events. Public records show similar actors have targeted multiple sectors over recent years, though specific prior activity tied to this listing remains limited to the current claim.
Who is Coldwell Banker UAE?
Coldwell Banker UAE operates as a real estate services firm within the broader Coldwell Banker network. Companies in this sector routinely collect and store client records related to property purchases, sales, rentals, and financing. These records often include personal identifiers, contact details, and financial documentation required for transactions. A breach at such an organisation can therefore involve data that spans multiple years of client interactions.
What data was at risk
The listing refers only to internal files exfiltrated in a ransomware attack. The exact types of data contained in those files have not been disclosed. Organisations of this kind commonly hold client names, addresses, identification documents, banking details, and contract information, but it is not confirmed whether any of these categories were present in the exfiltrated material.
Why it matters
Real estate records can contain information that remains useful for identity verification or financial fraud long after a transaction closes. When such data is removed from an organisation’s control, affected individuals face the possibility of misuse without immediate visibility into how or whether the files will be used. For the organisation, the incident adds operational and reputational considerations around data handling practices and client trust.

Publicly posted by coinbasecartel — unverified claim, pending independent verification
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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
