Integer Holdings Listed by coinbasecartel Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Integer Holdings, a US medical-device manufacturer based in Frisco, Texas, has been listed by the ransomware group coinbasecartel as a victim of a data-exfiltration attack. The listing was reported on November 10, 2025. Public detail remains limited: the number of people affected is unknown, and the only confirmed description of the material is that internal files were taken during a ransomware incident. The claim originates from the group’s leak-site listing and has not been independently verified in the available record.

Because Integer Holdings supplies critical components to original equipment manufacturers in cardiac, neuromodulation and vascular markets, any confirmed compromise of its internal systems carries potential consequences for the company, its partners and, indirectly, patients who rely on devices that incorporate its technology. At present the scale and exact contents of the claimed theft are undisclosed.

Inside the incident

According to the reported listing, coinbasecartel claims to have conducted a ransomware attack against Integer Holdings that resulted in the exfiltration of internal files. No further operational details—such as the initial access vector, the specific ransomware strain, the date the intrusion began, or the volume of data removed—have been made public. The number of individuals whose information may have been involved is listed as unknown. The sole concrete assertion available is that internal files were taken. Whether encryption was also deployed, whether a ransom demand was issued, and whether any data have been released remain unconfirmed beyond the group’s claim.

Who is coinbasecartel?

coinbasecartel is a ransomware operation that has appeared on public leak sites in recent years. Like many contemporary groups, it typically follows a double-extortion model: encrypting systems while simultaneously copying data and threatening to publish or sell the material if payment is not made. The group posts victim names and, in some cases, sample files on its leak site to increase pressure. Its listings are claims made by the actors themselves; they do not constitute independent confirmation that an organisation was successfully breached or that the stated data were in fact stolen. Prior activity attributed to the group has involved a range of commercial and industrial targets, though specifics of those earlier incidents are outside the scope of the present report.

Who is Integer Holdings?

Integer Holdings is a publicly known medical-device manufacturer headquartered in Frisco, Texas. The company designs and produces batteries, power systems and implantable components used in cardiac, neuromodulation and vascular applications. It supplies original equipment manufacturers across the medical, non-medical and portable-medical markets, positioning it as a specialised supplier within the global medical-device supply chain. Organisations of this type routinely hold engineering drawings, manufacturing process data, quality-control records, supplier contracts, employee information and, in some cases, limited clinical or regulatory documentation related to the devices they produce. A breach at such a firm is consequential because disruption or data exposure can affect not only the company itself but also the downstream manufacturers and healthcare providers that depend on its components.

The information in question

The only data type named in the available record is “internal files exfiltrated in ransomware attack.” No inventory of specific file categories, no count of records, and no confirmation of personal, financial or patient-related data have been published. Medical-device manufacturers typically maintain proprietary design files, production specifications, quality-assurance documentation, employee records, vendor contracts and regulatory correspondence. Whether any of those categories were among the files claimed by coinbasecartel is unconfirmed. Public statements have not identified particular data elements, so any assertion about the precise contents would be speculative.

What's at stake

For individuals whose information may have been present in the internal files, the primary risks are identity theft, phishing or social-engineering attempts that leverage any personal details that might have been exposed. Because the exact contents remain unknown, the severity of those risks cannot yet be quantified. For Integer Holdings the stakes include potential operational disruption, regulatory scrutiny under healthcare and data-protection rules, contractual obligations to customers, and reputational effects that could influence relationships with original equipment manufacturers. Downstream device makers and healthcare providers could face secondary concerns if proprietary manufacturing data or supply-chain information were compromised, although no such impact has been documented. Until more detail emerges, the concrete harm is limited to the uncertainty created by the group’s claim.

Were you affected?

If you are a current or former employee, contractor or business partner of Integer Holdings, monitor financial and email accounts for unusual activity and consider placing fraud alerts with credit bureaus. Change passwords on any work-related accounts that may have been reused elsewhere, and enable multi-factor authentication where available. Because the number of people affected and the precise data types remain unknown, there is no definitive public list of victims. Readers can run a free exposure scan of their email address against known breach data sets to check whether their information has already appeared in previously disclosed incidents. Any official notifications from Integer Holdings or law-enforcement agencies should be treated as the authoritative source of further guidance.
