Sibca Listed by thegentlemen Ransomware Group

On January 20, 2026, engineering firm Sibca appeared on the leak site of the ransomware group known as thegentlemen, with the attackers claiming to have exfiltrated internal files from the company’s systems.

What's Publicly Reported from Reporting

Public reporting indicates that Sibca, a provider of electrical and computer engineering services with roots as a family business, was listed on the group’s dark-web portal hosted at an onion address. The listing states that internal files were taken during a ransomware incident. No specific count of affected individuals has been released, and the precise volume or nature of the files remains unconfirmed by independent verification at the time of writing. The company’s website describes a workforce built around engineers recruited from leading universities, suggesting personnel records, project documentation, or client correspondence could be among the data at risk.

January 20, 2026 marks the public listing date. The primary source is thegentlemen’s own leak site, as tracked by ransomware.live. Secondary public details are limited.

Why This Matters for You and Your Family

When a company like Sibca suffers a breach, the people whose information ends up in the stolen files are often ordinary employees, former staff, clients, and their families. If your name, address, phone number, email, or employment details were stored in Sibca’s internal systems, those records may now sit on a ransomware leak site. Once posted, the data can be downloaded by anyone — identity thieves, stalkers, or opportunistic criminals — and used to target you directly.

Internal files exfiltrated in ransomware attacks frequently contain spreadsheets of employee contact information, contracts that list home addresses, or emails that reveal family relationships. Even if you never worked at Sibca yourself, a spouse, parent, or child who did could expose the entire household.

The Doxxing and Identity-Chain Implications

Stolen internal files rarely stay isolated. A single leaked email address or phone number can be fed into automated tools that link it to your social-media handles, gaming accounts, and family members’ profiles. This creates an identity chain that makes doxxing far easier. Public records, previous breach data, and the newly exposed Sibca files can be combined to build a complete picture of where you live, where your children go to school, and which online accounts you control.

Credential leaks of this kind frequently cascade into gaming account takeovers. Children’s usernames and passwords reused from family email addresses become entry points for attackers who then harass or extort the household. The speed at which these chains form leaves most people unaware until damage has already occurred.

Thegentlemen’s Publicly Known Track Record

Public reporting attributes thegentlemen as a ransomware operation that emerged in recent years and publishes victim data when ransom demands are not met. Their typical playbook involves gaining initial access, exfiltrating files before encryption, and then pressuring victims with threats of public release. Notable prior victims have included other mid-sized companies whose internal documents were posted on the same leak site. The group’s extortion style relies on the fear of reputational harm and downstream identity abuse rather than solely on file encryption.

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 the Sibca leak connects to.
• Rotate any password you used at Sibca or any related service, then enable 2FA through an authenticator app instead of text messages.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught and addressed within hours.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts vulnerable to the same credential chains.
• Let remediation specialists handle takedown requests and broker removals for you while you focus on securing accounts at home.

The incident shows that even companies with long-standing reputations can have their internal data exposed without warning. Taking concrete steps now limits how far the Sibca leak can reach into your life. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts. Starting that process today turns a reactive breach into a managed risk.
