Cambridge Mobile Telematics Listed by Coinbase Cartel Ransomware Group
If you are a customer of Cambridge Mobile Telematics, here’s what is being claimed, and what it would mean for you.
Cambridge Mobile Telematics (CMT) is an American telematics technology company headquartered in Cambridge, Massachusetts. It provides mobile-based driving analytics and safety solutions to insurers, rideshares, fleets, and enterprises. Using smartphone sensors and AI, CMT measures driving behavior to help reduce accidents and improve road safety. Its DriveWell platform is widely used in the insurance telematics industry globally.
— from Coinbase Cartel’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
Editor’s note: The claims described below originate from a ransomware group’s leak-site posting and have not been independently verified by GalaxyWarden. A listing of this kind is an assertion made by the group during an extortion attempt. It is not evidence that a breach occurred, and we report it as a claim rather than as a finding.

On June 12, 2026, the ransomware group known as CoinbaseCartel added Cambridge Mobile Telematics to its public leak site, claiming that it had exfiltrated internal files from the Massachusetts-based driving analytics company.
What Public Reporting Shows
Cambridge Mobile Telematics, or CMT, develops smartphone-sensor technology that insurers, rideshare companies, and fleets use to track driving behavior and reduce accidents. Public reporting indicates the company’s DriveWell platform is used by organizations worldwide. The CoinbaseCartel leak page lists CMT and states that internal files were taken during a ransomware incident. No specific victim count or list of exposed data types has been published on the leak site. Available reporting describes the posting as confirmation that negotiations failed and the group intends to publish or sell the stolen material. The exact date of initial compromise remains undisclosed in current public sources.
Why This Matters for You and Your Family
Even though CMT primarily serves businesses, the data it holds often includes personal driving records, insurance policy details, smartphone identifiers, and location history tied to individual drivers. If your insurer, rideshare app, or employer uses CMT’s technology, information linked to your phone or policy may now sit in an attacker’s hands. Credential leaks from such incidents frequently appear in follow-on sales on criminal forums. Once those credentials surface, anyone who reused the same email-and-password combination elsewhere faces immediate risk of account takeover. For families this can mean compromised email, banking apps, or children’s online gaming accounts that share the same contact details.

The Doxxing and Identity-Chain Implications
Ransomware groups rarely stop at one dataset. They map relationships between leaked emails, phone numbers, usernames, and real-world identities to create saleable “fullz” packages. A driving-analytics record that links your phone number to your insurance policy can be combined with other breaches to reveal home address, children’s names, or gaming handles. These chains accelerate doxxing: once attackers locate a family member’s Roblox, Fortnite, or Discord account, they can pivot to social engineering or direct extortion. Public reporting on similar incidents shows that gaming accounts are frequent secondary targets precisely because parents often reuse passwords or security questions across work-related services and family entertainment platforms.
CoinbaseCartel’s Publicly Known Track Record
Public reporting attributes the group’s first notable activity to late 2024. It has since listed dozens of organizations, focusing on mid-sized technology and service firms. Notable prior victims include payment processors and software vendors whose internal documents appeared on the same leak site. The group’s typical playbook begins with phishing or stolen credentials for initial access, followed by broad network exfiltration. After exfiltration they deploy ransomware, then wait a short period before listing the victim publicly if payment is not received. Their extortion style combines data-sale threats with selective publication of sample files to pressure targets. Readers can follow ongoing coverage of CoinbaseCartel through established ransomware trackers.
What to do
- Run a DoxxScan to map every link between your emails, phone numbers, handles, and real identity so you can see exactly what chains exist today.
- Rotate any password you used at Cambridge Mobile Telematics or connected insurance services, then enable two-factor authentication through an authenticator app everywhere that same password was reused.
- Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next leak exposing you or your family is caught and addressed in hours rather than months.
- Cover the household with DoxxScan family protection that extends to children’s gaming accounts and any other services that chain back to the same address or contact details.
- Let remediation specialists handle takedown requests across data brokers and exposed profiles while you focus on securing your own accounts.
The incident underscores a simple reality: data collected about your daily movements can become ammunition for identity thieves within days of a breach. Starting with a clear map of your exposure and maintaining continuous oversight gives you the best chance of staying ahead of attackers who treat personal information as an inventory to be sold. DoxxScan by GalaxyWarden delivers exactly that combination of continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists who also protect gaming accounts belonging to you or your children.
