Termotasajero Listed by sinobi Ransomware Group

On October 8, 2025, Colombian power generation company Termotasajero SA ESP appeared on the leak site of the sinobi ransomware group. Internal files were allegedly exfiltrated during a ransomware attack, and the company now faces public exposure of sensitive business data that could affect anyone whose personal information was stored in those systems.

What's Publicly Reported from Reporting

Public reporting indicates that sinobi listed Termotasajero on its dark web leak portal, claiming to have stolen internal documents. The company generates and sells electricity across Colombia with a focus on sustainable operations. No exact count of affected individuals has been released, and the precise volume or sensitivity of the stolen files remains unclear from available reporting. The listing appeared on the sinobi leak site, accessible via the .onion address tracked by ransomware.live.

Why This Matters for You and Your Family

When a utility company like Termotasajero suffers a breach, the ripple effects reach ordinary households. Billing records, service contracts, payment details, and correspondence often contain names, addresses, phone numbers, email accounts, and sometimes national identification numbers. Internal files exfiltrated in these attacks frequently include spreadsheets that mix corporate data with customer information. If your household is a client, your data may now sit on a criminal forum where it can be sold or used to launch further attacks. Criminals treat such leaks as starter packs for identity theft, account takeovers, and phishing campaigns aimed at you and your family.

The Doxxing and Identity-Chain Implications

Leaked utility data rarely stays isolated. An email address exposed in the Termotasajero files can be cross-referenced with credentials from earlier breaches, linking your work account to personal services, social media, and even your children’s online profiles. This creates an identity chain that lets attackers map handles to real names, home addresses, and family relationships. Public reporting describes how such chains accelerate doxxing, where personal details are published to harass or extort victims. Gaming accounts belonging to teenagers are especially vulnerable because kids often reuse passwords or email addresses tied to family utility bills. A single credential leak can cascade into full account takeovers across platforms.

Sinobi’s Publicly Known Track Record

Public reporting attributes the sinobi ransomware group with activity that emerged in recent years. The group follows a classic double-extortion playbook: it first gains initial access, exfiltrates data, then encrypts systems and demands payment to prevent publication. Notable prior victims include other mid-sized companies whose internal files were posted on the same leak site when ransom demands went unmet. Sinobi typically posts samples of stolen data and sets deadlines for payment before releasing larger archives. Exact timelines and earlier victim counts vary across reports, but the pattern of stealing, encrypting, and publicly shaming non-paying targets remains consistent.

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 chains back to the Termotasajero breach.
• Rotate any password you used for Termotasajero services or any account sharing those credentials, then enable 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 and addressed within hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and your children’s gaming accounts, which often become targets when household data leaks.
• Let DoxxScan remediation specialists handle takedown requests and broker removals for you while you focus on securing accounts at home.
