C*** | A******** - Contact us by monday Listed by Coinbase Cartel Ransomware Group

On December 12, 2025, the ransomware group known as CoinbaseCartel publicly listed a company called Secret on its leak site, claiming to hold 2TB of internal files exfiltrated during a ransomware attack and giving the victim until Monday to contact them.

What Public Reporting Shows

Public reporting on the ransomware.live tracker describes the incident as a classic double-extortion case. The group states it has exfiltrated internal files and posted proof in a private chat. The listing appeared on the dark-web leak site on December 12, 2025, with a short deadline for the victim to respond. The exact number of individuals whose data may be contained in the 2TB is listed as unknown. No sample data has been published on the leak site so far, which is consistent with the group’s pattern of keeping proof private until the deadline passes.

The compromised system involved internal file servers rather than a customer-facing database. This means employee records, contracts, financial documents, and any personal information stored in shared drives could be at risk if the files are later released.

Why This Matters for You and Your Family

When a company you have dealt with loses control of internal files, your personal information can end up in the hands of criminals without you ever receiving a direct notification. Names, addresses, dates of birth, phone numbers, email accounts, and even scanned documents that contain Social Security numbers or children’s information are common contents of corporate file shares. Once that material leaves the company’s control, it can be sold, traded, or used to target you directly.

Credential leaks from these incidents often cascade into gaming accounts, email takeovers, and further identity theft. If your family uses the same password for work-related services and for online games or streaming accounts, one breach can quickly expose your children’s handles and chat logs as well.

The Doxxing and Identity-Chain Implications

Ransomware operators rarely stop at dumping raw files. They or the buyers who purchase the data frequently map relationships between corporate emails, personal accounts, and family members. A single leaked spreadsheet can link your work email to your home address, your child’s school records, and gaming usernames. These connections create what security analysts call an identity chain — a map that makes targeted doxxing, phishing, and SIM-swapping far easier. Public reporting indicates that data from ransomware leaks frequently appears on multiple underground forums within weeks of a deadline passing.

CoinbaseCartel’s Publicly Known Track Record

Public reporting attributes the CoinbaseCartel name to a ransomware operation that emerged in late 2024. The group has claimed responsibility for attacks on a range of mid-sized organizations, often in the technology and professional-services sectors. Its typical playbook begins with initial access gained through compromised credentials or phishing, followed by rapid exfiltration of internal file shares. The cartel then deploys ransomware and simultaneously threatens to publish the stolen data on its leak site if the victim does not pay. Extortion deadlines are usually measured in days rather than weeks, and the group has shown willingness to release initial proof-of-compromise samples when victims ignore contact attempts.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity so you can see exactly what this leak may have exposed.
• Rotate any password you used at the breached company anywhere else it is reused, and switch to 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught within hours instead of months.
• Cover the household with DoxxScan family protection that includes dependents and children’s gaming accounts, which often become the next link in doxxing chains after credential leaks like this one.
• Let remediation specialists handle takedown requests and broker removals for you while you focus on securing accounts at home.

The speed with which ransomware data moves from leak sites into criminal marketplaces means families must act before the Monday deadline becomes a public dump. Starting with a clear map of your exposed digital footprint gives you the best chance of stopping the next stage of the attack before it reaches your inbox or your child’s gaming profile. DoxxScan by GalaxyWarden delivers that continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts.
