Siveco - Listed by coinbasecartel Ransomware Group

On May 30, 2026, French software company Siveco appeared on the leak site of the ransomware group known as coinbasecartel. Internal files were allegedly exfiltrated during a ransomware attack, and the data is now publicly listed, potentially exposing information tied to the company’s operations, partners, and individuals whose details appear in those files.

What's Publicly Reported from Reporting

Public reporting indicates that Siveco, which develops computerized maintenance management systems and enterprise asset management software, had internal documents stolen. The company serves clients in energy, transportation, manufacturing, and public utilities across Europe, Africa, and Asia. No exact victim count has been released, and the precise volume or sensitivity of the leaked files remains unclear from available reporting. The listing appeared on the coinbasecartel leak site hosted on the dark web, with the primary source being the onion address published via ransomware.live.

Why This Matters for You and Your Family

When a company like Siveco suffers a breach, the ripple effects reach far beyond its walls. Internal files often contain contracts, employee records, customer contact details, project specifications, and credentials that can be used to target individuals. If your employer, utility provider, or children’s school uses Siveco software, your personal information or household data may now sit in an attacker’s archive. Once that data reaches public forums or underground markets, it can fuel identity theft, phishing campaigns, or harassment that directly affects you and your family.

The Doxxing and Identity-Chain Risks

Stolen internal files frequently include email addresses, usernames, phone numbers, and project notes that link online handles to real-world identities. These fragments allow attackers to build identity chains—connecting your work email to personal accounts, social profiles, and even your children’s gaming usernames. Credential leaks of this kind commonly cascade into account takeovers. A single exposed password reused across services can let attackers seize control of email, banking, or gaming accounts, then publish personal details for harassment or further extortion.

Coinbasecartel’s Publicly Known Track Record

Public reporting attributes the coinbasecartel ransomware group with operations that emerged in recent years. The group is known for targeting organizations, exfiltrating data, and then publishing samples on leak sites to pressure victims into payment. Their typical playbook involves initial access through common vulnerabilities or phishing, followed by data exfiltration and extortion demands backed by the threat of full disclosure. Notable prior victims have included various companies whose internal documents were later listed on similar dark-web portals.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real identity so you can see exactly what this leak may have exposed.
• Rotate any password you used at Siveco or related services anywhere it is reused, and switch on 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 exposure of your data is caught in hours, not months.
• Cover the household with DoxxScan family protection that extends to dependents and your children’s gaming accounts, which often chain back to the same addresses and credentials.
• Let remediation specialists handle takedown requests and broker removals for you while you focus on securing your own accounts.
