Hanlon Electric Listed by sinobi Ransomware Group

On December 22, 2025, electrical contractor Hanlon Electric appeared on the leak site of the sinobi ransomware group, with attackers claiming to have exfiltrated internal files from the Pittsburgh-based company.

What's Publicly Reported from Reporting

Public reporting indicates that Hanlon Electric, a firm founded in 1930 that provides electrical construction, building maintenance, telecommunications, and energy-efficiency services to commercial, industrial, educational, and medical clients, was listed on the sinobi ransomware leak portal. The group states it stole internal company files during a ransomware incident. No specific volume of records or exact data types has been independently verified in available reporting, and the number of individuals whose information may be exposed remains unknown. The listing appeared on an onion-site address tracked by ransomware.live.

Why This Matters for You and Your Family

When a local business like an electrical contractor suffers a breach, the information stolen can easily include documents containing customer names, addresses, phone numbers, email accounts, and payment details. If you or your family have ever hired an electrician, worked with a contractor on a home renovation, or received services from a company in the Pittsburgh region that partners with firms like Hanlon, your personal data could be among the records now in attackers’ hands. Credential leaks from such incidents frequently cascade into account takeovers on personal email, banking, or shopping sites where the same password was reused.

Children’s information is not immune. Many families share email addresses or phone numbers across household accounts, and gaming usernames linked to those emails can become entry points for further harassment or extortion.

The Doxxing and Identity-Chain Risks

Stolen internal files often contain spreadsheets, contracts, or contact lists that link a person’s real name and street address to online handles, email addresses, or phone numbers. Attackers and subsequent data resellers can chain these fragments together to build detailed profiles. What begins as a contractor’s customer record can surface on people-search sites, underground forums, or social-media doxx lists. Once the chain exists, a single additional breach—perhaps from a gaming platform or school portal—can expose far more than the original leak suggested.

Sinobi Group’s Known Track Record

Public reporting attributes the sinobi ransomware operation to a group that emerged in recent years and has targeted organizations across multiple sectors. The group’s typical playbook involves gaining initial access, exfiltrating data before deploying ransomware, and then publishing samples or full datasets on its leak site when victims do not pay the demanded ransom. Notable prior victims have included companies in manufacturing, services, and local-government adjacent industries, though exact details vary by incident. Observers note that sinobi follows an extortion style that combines data publication pressure with deadlines that can range from days to weeks.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what chains exist from this and earlier breaches.
• Rotate any password you ever used with Hanlon Electric or related contractors anywhere it has been reused, then enable 2FA through an authenticator app rather than 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 instead of months.
• Cover the entire household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become targets when credential leaks create doxxing chains.
• Let remediation specialists handle the time-consuming work of sending takedown requests to data brokers and monitoring follow-on exposure that stems from this incident.

The incident shows that even established local companies can become links in larger identity-exposure chains that reach your front door. Taking targeted steps now limits how far attackers can travel with the information they obtained. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping that connects scattered handles to real identities, and hands-on remediation by specialists who manage takedowns for you and your family—including children’s gaming accounts that frequently serve as the next link in doxxing attempts.
