CIGAM Software Corporativo Ltda Listed by coinbasecartel Ransomware Group

On November 20, 2025, Brazilian ERP provider CIGAM Software Corporativo Ltda appeared on the leak site of the coinbasecartel ransomware group, with internal files exfiltrated during a ransomware attack.

What Public Reporting Shows

Available reporting describes the listing on the coinbasecartel leak site hosted via ransomware.live. The company develops and sells an ERP platform used by medium and large organizations for financial management, inventory, sales, and other core operations. Public reporting indicates that attackers gained access, exfiltrated internal files, and later published the data after CIGAM did not meet their demands. Exact victim counts inside the company remain unknown, and the precise volume or sensitivity of the files has not been independently verified beyond the group’s own claims. The incident follows the group’s typical pattern of initial access, data theft, and public extortion.

Why This Matters for You and Your Family

When a company that handles business records for other organizations is breached, the ripple effects often reach ordinary people. Employee records, vendor contracts, customer invoices, or partner contact details inside those internal files can contain names, addresses, tax IDs, phone numbers, and email accounts that belong to you or members of your household. Once exposed, this information rarely stays contained. It can be sold, combined with other leaks, and used to target you with identity theft, phishing, or harassment. Your family’s privacy is directly affected even if you have never heard of CIGAM before today.

The Doxxing and Identity-Chain Implications

Ransomware leaks like this one frequently accelerate doxxing chains. A single exposed email or phone number from corporate files can be cross-referenced with gaming accounts, social-media handles, or family-member profiles. Attackers or opportunistic criminals then map these connections to build a complete picture of your household. Credential leaks of this nature commonly cascade into account takeovers on personal services, including gaming platforms used by children. What begins as a corporate ransomware incident can quickly become personal when the same password or contact detail appears in multiple places.

Coinbasecartel’s Publicly Known Track Record

Public reporting attributes coinbasecartel with emerging in late 2024 as a ransomware operation that combines data theft with extortion. The group has listed multiple companies across different sectors, typically following a playbook of gaining initial network access, exfiltrating sensitive files, and then publishing samples on their leak site when victims refuse payment. Their name and branding reference cryptocurrency, though their attacks have focused on traditional businesses rather than solely crypto targets. Exact success rates and prior victim counts fluctuate in open sources, but the group maintains an active presence on dark-web leak portals.

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 used at CIGAM or related business services anywhere it is reused, and switch on 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your data is caught in hours instead of months.
• Cover the entire household with DoxxScan family protection, which includes dependents and children’s gaming accounts that often chain back to the same contact details.
• Let remediation specialists handle takedown requests for any personal information already circulating from this or connected leaks.

The CIGAM incident illustrates how corporate ransomware attacks increasingly expose the personal details of everyday families.
