Sampol Listed by Coinbase Cartel Ransomware Group

Sampol Listed by Coinbase Cartel Ransomware Group

On April 15, 2026, Spanish engineering company Sampol appeared on the leak site of the ransomware group known as coinbasecartel. Internal files were allegedly exfiltrated during a ransomware attack on the Mallorca-headquartered firm, which provides electrical installations, renewable energy solutions, facility management, and industrial automation services across Spain and international markets.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

Reported Details of the Incident

Public reporting indicates that coinbasecartel added Sampol to its data leak portal on that date. The company, which serves both public and private clients in the energy, industrial, and infrastructure sectors, may have had internal files stolen. Available reporting describes the exposed material as company documents rather than customer databases, though the exact volume and specific contents remain unclear from current public sources. No confirmed count of affected individuals has been released.

Why This Matters for You and Your Family

When a company like Sampol suffers a breach, the ripple effects often reach ordinary people. Employees, contractors, clients, and their families can find personal details caught up in stolen files. Internal files frequently contain names, addresses, contact information, project details, and sometimes financial records that can be pieced together with other leaks. If your employer, your utility provider, or a contractor you hire uses Sampol’s services, your information could be exposed. For families this means increased risk of identity theft, phishing campaigns tailored with real details from the files, and potential harassment if addresses or family member names surface in the wrong hands.

The Doxxing and Identity-Chain Risks

Stolen internal files rarely stay isolated. Attackers and opportunistic criminals combine them with data from previous breaches to build detailed profiles. A work email from one leak, a home address from another, and a child’s name from a third can quickly create a full identity chain. This chaining process turns a single corporate incident into personal doxxing that can affect every member of a household. Gaming accounts belonging to children are especially vulnerable because usernames and emails often link back to family addresses or parent accounts, allowing attackers to move from corporate data to personal takeovers.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
