Questivity Listed by Coinbase Cartel Ransomware Group

On April 15, 2026, the ransomware group known as coinbasecartel added Questivity to its public leak site, claiming that internal files had been exfiltrated from the company during a ransomware attack.

What Public Reporting Shows

Public reporting indicates the incident involves a successful ransomware deployment followed by data exfiltration. The coinbasecartel leak page lists Questivity and displays samples of the stolen material. No exact victim count has been disclosed, and the precise number of people whose information appears in the files remains unknown. Available reporting describes the exposed data as internal files, though the full scope of personal information contained in those documents has not been independently verified by third parties.

Why This Matters for You and Your Family

When a company’s internal files are stolen and published, the information inside can include names, addresses, phone numbers, email accounts, dates of birth, and other details that belong to ordinary customers, employees, or vendors. If your data was among the records handled by Questivity, it is now at risk of being downloaded by anyone who visits the leak site. Once posted to a ransomware leak page, the clock starts for identity thieves, fraudsters, and harassers who routinely scan these repositories. For families, a single exposed record can lead to unexpected charges, loan applications in your name, or unwanted contact that affects every member of the household.

The Doxxing and Identity-Chain Implications

Stolen internal files frequently contain more than isolated records. They can link email addresses to phone numbers, physical addresses, account usernames, and even notes about family members. Attackers use these connections to build an identity chain that reveals far more than any single breach. A work email listed in one file can be matched to a personal gaming account; a phone number can be tied to social-media handles. This chaining turns a routine data leak into a roadmap for doxxing. Credential leaks like this one regularly cascade into account takeovers, especially for gaming platforms where children’s accounts are often secured with the same passwords or recovery emails used elsewhere.

Coinbasecartel’s Publicly Known Track Record

Public reporting attributes the group’s emergence to mid-2024. Since then, coinbasecartel has listed dozens of organizations on its leak site, typically following the same pattern: initial access through phishing or exploited remote desktop credentials, followed by deployment of ransomware, exfiltration of internal documents, and publication on its dark-web portal when victims do not pay. Notable prior victims include mid-sized service providers and technology firms. The group’s playbook relies on pressure through public exposure rather than prolonged negotiation, often setting short deadlines for payment before releasing additional batches of data.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what chains exist from this incident.
• Rotate any password you used at Questivity anywhere else it appears, then enable two-factor authentication 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 surfaces you learn within hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become targets when credential leaks create doxxing chains.
• Let remediation specialists handle the follow-up work, including takedown requests to data brokers and monitoring for resale of the stolen Questivity files.

The incident shows that even companies you may never have heard of can hold pieces of your personal story. Acting quickly limits how far those pieces can travel. Start your DoxxScan trial today and put continuous monitoring, identity-chain mapping, and hands-on remediation specialists to work for you and your family, including protection for gaming accounts that frequently get swept up in these cascades.
