Details from the Leak Site
The RansomHub portal entry for mataderodegijon.es states that the company was hit in a ransomware attack and that internal files were taken. It records 90 visits to the victim page and lists the exfiltrated material as 15 GB. The disclosure does not specify which exact records were allegedly stolen, whether customer, employee, supplier or operational data, nor does it give any deadline for publication. The primary source is the RansomHub onion link hosted via ransomware.live, which serves as the official attacker-controlled disclosure channel.
Why This Matters for You and Your Family
When a local energy infrastructure operator like Matadero de Gijón loses control of internal files, anyone whose personal information passed through the company may be exposed. Suppliers, contractors, employees and even residents whose utility or environmental records sit in those systems now face the possibility that their details are sitting in a criminal archive. Even if the exact data types are not yet public, the mere fact that 15 GB of internal files left the network means names, addresses, contact details, contract numbers or payment records could be included. For ordinary families, this translates into heightened risk of identity theft, phishing campaigns and unwanted solicitations that can last for years.
The Doxxing and Identity-Chain Risk
Ransomware operators rarely stop at one dataset. A single leaked email or phone number from this claimed breach can be chained with information from previous incidents to build a complete profile. Attackers link your work email to personal accounts, gaming handles, family addresses and children’s online profiles. Once those connections are mapped, targeted doxxing, SIM-swapping or extortion attempts become far easier. Credential leaks of this kind frequently cascade into gaming account takeovers, especially for households where the same password is reused across business and personal services.
