ThreatAI Analysis

Compiled from this incident record and the threat intelligence profile for Coinbasecartel. Figures and technique mappings are quoted from the source data, not inferred.

About the Coinbasecartel group

CoinbaseCartel specializes in data acquisition through system access and strategic partnerships. It focus exclusively on data exfiltration—our operations never involve system encryption or operational disruption. Coinbasecartel has listed 186 victims since May 2023.

How Coinbasecartel is documented to operate

Replication Through Removable Media T1091 Lateral Movement Initial Access

Adversaries may move onto systems, possibly those on disconnected or air-gapped networks, by copying malware to removable media and taking advantage of Autorun features when the media is inserted into a system and executes. In the case of Lateral Movement, this may occur through modification of executable files stored on removable media or by copying malware and renaming it to look like a legitimate file to trick users into executing it on a separate system. In the case of Initial Access, this may occur through manual manipulation of the media, modification of systems used to initially format the media, or modification to the media's firmware itself.

Mitigations: Limit Hardware Installation, Behavior Prevention on Endpoint, Disable or Remove Feature or Program

External Remote Services T1133 Persistence Initial Access

Adversaries may leverage external-facing remote services to initially access and/or persist within a network. Remote services such as VPNs, Citrix, and other access mechanisms allow users to connect to internal enterprise network resources from external locations. There are often remote service gateways that manage connections and credential authentication for these services. Services such as Windows Remote Management and VNC can also be used externally. Access to Valid Accounts to use the service is often a requirement, which could be obtained through credential pharming or by obtaining the credentials from users after compromising the enterprise network.

Mitigations: Limit Access to Resource Over Network, Restrict Web-Based Content, Network Segmentation, Multi-factor Authentication, Disable or Remove Feature or Program

Incident Analysis

Buffalo Neuroimaging Analysis Center was targeted by Coinbasecartel ransomware, one of the most active ransomware groups in our database with 208 confirmed victims globally. The attack was disclosed on March 30, 2026, when Buffalo Neuroimaging Analysis Center appeared on the group's dark web leak site.

Buffalo Neuroimaging Analysis Center is based in United States , operating in the Healthcare sector. United States ranks #1 globally for ransomware attacks, with 9,442 victims in our database.

Sector context: Healthcare organisations are high-value ransomware targets because patient data is extremely sensitive, regulatory penalties for breaches are severe, and operational downtime can threaten patient safety — all factors that increase ransom payment pressure.

Coinbasecartel typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data. Last data update: Sep 8, 2026 06:00 UTC.
