hbexperts-conseils.ca Listed by m3rx Ransomware Group

On June 11, 2026, the Canadian consulting firm HB Experts Conseils appeared on the leak site of the m3rx ransomware group, with attackers claiming to have stolen 105 GB of internal files containing 68,000 documents.

Confirmed Facts from Reporting

Public reporting indicates the firm, which provides building science, roof, pavement, and building envelope consulting services across construction and maintenance sectors, was hit by a ransomware operation. The m3rx group posted proof of the breach on its dark-web leak site, listing the Canadian phone number +1 (514) 882-6463 associated with the company. Available reporting describes the exfiltrated material as internal files rather than a traditional customer database. No confirmed count of affected individuals has been released, leaving many clients and partners uncertain whether their information is among the stolen data.

105 GB and 68,000 files represent a substantial volume that could include contracts, project specifications, employee records, and correspondence. The incident follows the group’s typical pattern of encrypting systems, exfiltrating data, then threatening public release unless a ransom is paid.

Why This Matters for You and Your Family

When a company you have hired to inspect your roof, assess your building envelope, or consult on pavement maintenance suffers a breach, your personal or household information can be exposed. Addresses, phone numbers, email communications, payment details, and project notes often sit in those internal files. Once leaked, this information can be combined with other records to build a profile that puts your family at risk of identity theft, targeted scams, or unwanted solicitations. Even if you are not the direct victim, the reality is that ordinary people who simply hired a reputable consulting firm now face the downstream consequences.

Credential leaks like this one frequently cascade into account takeovers on unrelated services where the same email and password were reused. For families, the exposure can reach children’s accounts when shared family emails or addresses appear in the stolen documents.

The Doxxing and Identity-Chain Implications

Ransomware operators rarely stop at dumping raw files. They or subsequent buyers scan the material for any personally identifiable information that can be chained together. A home address listed in a roof-inspection report can be linked to an email address, which in turn matches a username on a gaming platform or social account. This identity chain turns a single breach into a roadmap for doxxing, harassment, or fraud. Public reporting on similar incidents shows that children’s information, when inadvertently included through family projects or school-related building consultations, can accelerate these chains because gaming handles and parent accounts often share the same contact details.

m3rx Group Track Record

Public reporting attributes the m3rx ransomware group with emerging in late 2024. The group has targeted mid-sized organizations across North America and Europe, with prior victims including manufacturing firms, professional service providers, and local government contractors. Their publicly known playbook involves initial access through phishing or exploited remote desktop protocols, followed by rapid exfiltration of internal shares, deployment of ransomware encryption, and extortion via dual pressure: locked systems plus the threat of publishing stolen files on their leak site. They typically set short payment deadlines measured in days and increase pressure by releasing small samples before dumping larger archives if unpaid.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity so you can see exactly what chains back to the HB Experts Conseils breach.
• Rotate any password you used at hbexperts-conseils.ca or with the firm anywhere it is reused, and switch on 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 15.4B+ breach records and 100+ platforms so the next exposure of your information is caught in hours, not months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become the next link in doxxing chains when parent data is exposed.
• Let remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing your own accounts.
