Doman Building Materials Group Listed by interlock Ransomware Group

On March 11, 2025, Canadian building materials supplier Doman Building Materials Group appeared on the leak site of the interlock ransomware group. The company, which supplies lumber and specialty wood products to retailers across North America, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of people whose information may have been exposed remains unknown, anyone whose personal or employment records were stored in Doman’s systems could now be at risk.

Reported Details from Reports

Public reporting indicates that interlock posted proof of the breach on its dark-web leak site, listing Doman Building Materials Group as a victim. The data taken includes internal files that ransomware operators typically harvest before encrypting systems. No confirmed total of affected records has been published, and the company has not yet issued a detailed public statement on the precise data types involved. The listing appeared on March 11, 2025, giving observers a clear timeline of when the threat actor chose to publicize the incident.

Why This Matters for You and Your Family

When a company like Doman suffers a breach, the information it holds on suppliers, customers, employees, and contractors can end up in criminal hands. That data often contains names, addresses, phone numbers, email accounts, and sometimes dates of birth or government identifiers. Once exposed, these details become building blocks that identity thieves or harassers can use against you or your family members. Even if you never shopped at a Doman retailer, an employee, vendor, or contractor connection could still place your information in the stolen files.

Credential leaks from corporate networks frequently cascade into personal account takeovers. If you or your children reuse work-related passwords on gaming platforms, email, or shopping sites, criminals can move quickly from corporate data to personal targets.

The Doxxing and Identity-Chain Risk

Ransomware groups rarely stop at dumping raw files. They map relationships between corporate emails, personal handles, phone numbers, and real-world identities. This creates an identity chain that can lead to doxxing, targeted phishing, or extortion attempts against individuals. A single leaked work document can reveal your home address, spouse’s name, or children’s details if those records were stored in the compromised systems. Gaming accounts belonging to teenagers are especially vulnerable because they often share the same email domain or password patterns found in a parent’s work breach.

Interlock Ransomware Group’s Track Record

Public reporting attributes the attack to the interlock ransomware group. The group emerged in recent years and has targeted organizations across multiple sectors by gaining initial access through common vectors such as phishing or unpatched remote desktop services. After exfiltrating sensitive files, interlock’s typical playbook involves encrypting victim systems and then demanding payment to prevent publication of the stolen data. Notable prior victims include other mid-sized companies whose internal documents were later posted on dark-web leak sites when negotiations failed. Exact success rates and total victims remain difficult to verify, but the group’s consistent use of public shaming suggests it prioritizes pressure through data exposure.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, online handles, and real identity so you can see exactly what chains back to the Doman breach.
• Rotate any password you used at Doman or any related vendor account, 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 leak that touches your family is caught in hours rather than months.
• Cover the entire household with DoxxScan family protection that includes children’s gaming accounts, which often become targets when corporate credential leaks create doxxing chains.
• Let remediation specialists handle takedown requests for any exposed personal information found on data broker sites or forums.
