Solarpro Holding Listed by Coinbase Cartel Ransomware Group

On December 12, 2025, Solarpro Holding appeared on the leak site of the ransomware group known as coinbasecartel. The company, a major EPC contractor that designs and builds photovoltaic power plants, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of people whose information may have been exposed remains unknown, anyone whose personal or employment records were stored in those systems could now be at risk.

What Public Reporting Shows

Public reporting indicates that coinbasecartel posted proof of the breach on its dark-web leak site, accessible via the onion address hosted on the ransomware.live tracker. The data consists of internal files exfiltrated after the group deployed ransomware against Solarpro Holding’s networks. No confirmed total of affected individuals has been released, and the precise contents of the leaked files have not been independently verified by third parties. The incident follows the group’s typical pattern of stealing data before encrypting systems and then threatening public release unless a ransom is paid.

Why This Matters for You and Your Family

When a company like Solarpro Holding loses control of internal files, the information inside often includes employee records, contractor details, customer contracts, and correspondence that can contain names, addresses, phone numbers, email accounts, and sometimes financial or identification data. If you or anyone in your family has ever worked with Solarpro, applied for a job there, or appeared in their vendor or customer databases, your information may now be in attackers’ hands. That single exposure can serve as the starting point for identity theft, phishing campaigns, or more targeted harassment. For families, the risk extends beyond the primary account holder: children’s names linked to a parent’s employment record can become part of the same data set.

The Doxxing and Identity-Chain Risk

Stolen internal files rarely stay isolated. Attackers and subsequent buyers frequently combine them with other breaches to build detailed profiles. A work email from the Solarpro leak can be matched to personal accounts, social-media handles, or gaming usernames. Once those connections are made, doxxing chains form quickly—leading to harassment, swatting, or account takeovers across services. Credential leaks of this kind are especially dangerous for gaming accounts because the same password or recovery email used for a child’s Roblox, Fortnite, or Steam profile may also appear in corporate documents. Available reporting describes how these cascades have turned routine business breaches into long-term privacy nightmares for ordinary families.
