Lonestar Truck Group & Tag Truck Center Listed by interlock Ransomware Group

On May 4, 2026, the interlock Ransomware Group added Lonestar Truck Group and its affiliated Tag Truck Center to its leak site, publishing internal files that include employee personal data, customer records, business contact information, and confidential financial documents.

Reported Details of the Breach

Public reporting indicates that Lonestar Truck Group, which operates multiple dealerships selling new and used trucks, trailers, and related service and parts, suffered a ransomware attack. The attackers exfiltrated internal files before encrypting systems or otherwise disrupting operations. The data now listed on the interlock leak site contains records belonging to employees, customers, and partner companies. No exact victim count has been disclosed, but the volume is described as significant given the company’s broad customer base across commercial and individual buyers.

Available reporting describes the exposed materials as a mix of personally identifiable information, contact details, and sensitive business documents. The interlock group has given the customary deadline for payment before further data is released or sold, although the precise date has not been independently verified in open sources.

Why This Matters for You and Your Family

If you have ever bought or serviced a vehicle through Lonestar Truck Group or Tag Truck Center, your name, address, phone number, email, or payment-related records may now be circulating among criminals. The same applies if you or a family member worked there or if your business purchased fleet vehicles or parts. Once this type of information leaves a company’s control, it rarely stays contained. It can be combined with other leaks to build a detailed profile that makes identity theft, targeted phishing, or harassment far easier.

Customer records and employee personal data are especially valuable because they often include dates of birth, driver’s license numbers, or Social Security numbers that many dealerships still collect for financing, registration, or employment forms. For ordinary families, this translates into months or years of potential fraud alerts, unexpected loan applications in your name, and increased spam or scam calls.

The Doxxing and Identity-Chain Risks

Ransomware leaks like this one rarely stop at the initial data set. Criminals routinely cross-reference newly exposed emails, phone numbers, and addresses against older breaches. A single customer record from a truck dealership can link to your online usernames, social-media accounts, or children’s gaming profiles. That linkage turns a simple data leak into a doxxing chain: attackers map your digital footprint, locate family members, and escalate from identity theft to extortion or public harassment.

Credential leaks cascade into account takeovers when the same password was reused at the dealership portal, an email provider, or an online game. Children’s gaming accounts are particularly vulnerable because parents often share an email or phone number across family services. Once those gaming handles are tied to a real identity and home address, the risk of swatting, doxxing, or targeted scams rises sharply.

Interlock Ransomware Group’s Track Record

Public reporting attributes the attack to the interlock Ransomware Group, which emerged in late 2024. The group has targeted mid-sized businesses across logistics, manufacturing, and retail sectors. Notable prior victims include transportation and parts suppliers whose customer and employee data were published after ransom demands went unpaid. Their typical playbook begins with initial access through phishing or exploited remote desktop services, followed by exfiltration of sensitive files over several weeks. They then encrypt systems and post samples on their leak site, using a double-extortion model that combines encryption with the threat of public data release. Payment deadlines are usually set between seven and fourteen days after the initial listing.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, addresses, and online handles that may have been exposed in the Lonestar files.
