provencherroy.ca Listed by Black Basta Ransomware Group

On April 1, 2024, Canadian architecture and design firm Provencher Roy appeared on the leak site of the Black Basta ransomware group. The listing states that internal files totaling roughly 3 TB were exfiltrated during a ransomware attack. The firm, which specializes in inclusive and sustainable building design, has not yet published its own breach notification, leaving the exact number of affected individuals unknown.

Details in the Leak-Site Listing

The Black Basta post explicitly lists the victim as provencherroy.ca and provides the company’s Montreal headquarters address, telephone number, and a high-level inventory of the stolen material. Categories include 2023 and 2024 projects, CAD and 3D drawings, Ottawa project data, corporate HR and finance records, and assorted personal employee documents. The disclosure indicates the data was taken before encryption and is now held for extortion purposes. No sample files have been published at the time of writing, and the listing does not quantify how many employee or client records are contained inside the 3 TB archive.

Why This Matters for You and Your Family

When an architecture firm’s internal files are stolen, the exposure often reaches beyond company walls. Employees’ personal documents, payroll spreadsheets, tax forms, and correspondence can contain home addresses, dates of birth, Social Insurance Numbers, and family details. If you or a family member worked at Provencher Roy or had projects with them, your information may now sit on a criminal server. Even if you are not an employee, client contracts, property records, or vendor files can indirectly expose household addresses and financial relationships that criminals later exploit.

Personal employee documents are among the most dangerous leaks because they link workplace identity to private life in one convenient package. Once that bundle reaches dark-web markets, it becomes raw material for identity theft, loan fraud, and targeted phishing against you and anyone connected to you.

The Doxxing and Identity-Chain Risk

Ransomware leaks rarely stop at one dataset. A single exposed email or phone number from the HR files can be cross-referenced with gaming accounts, social-media handles, and data-broker records to build a complete profile. Children’s names or school-related project files sometimes appear in architectural client folders; those details can chain into gaming usernames that use the same password. The result is a doxxing cascade: one breach exposes an email, that email unlocks a reused password on a child’s Roblox or Minecraft account, and the attacker then publishes the family home address alongside screenshots from the game. Continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, combined with AI-powered identity-chain mapping, is one of the few practical ways to spot these linkages before they are exploited.

Black Basta’s Publicly Known Track Record

Public reporting attributes the first Black Basta activity to early 2022. The group rapidly became one of the most active ransomware operations, typically compromising Windows networks via phishing emails, remote-desktop brute force, or stolen credentials. After gaining access they exfiltrate sensitive files, deploy their signature double-extortion ransomware, and publish victim data on their leak site if payment is not made. Notable prior victims include large manufacturers, healthcare providers, and professional-services firms. Their playbook emphasizes speed: data is stolen within days of initial access, followed by a ransom demand and a short negotiation window before files appear on the onion site. The group frequently rebrands or adjusts its leak-site domains, making ongoing tracking essential.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, including cleanup of exposed records.
• Rotate any password you used at Provencher Roy or any related service, then enable 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring so the next breach exposing your family is caught in hours, not months.
• Cover the household — DoxxScan family coverage extends to dependents and children’s gaming accounts that often chain back to the same breached address or email.
• Let remediation specialists handle takedown requests across data brokers and leak sites on your behalf.

The incident underscores a persistent reality: architectural and professional-services firms hold intimate details about where families live, work, and play, and those details are now prime targets. Staying ahead requires more than changing a password. Start your DoxxScan trial and let its continuous monitoring across 13.1B+ breach records, identity-chain mapping, and hands-on remediation specialists work for your entire household, including gaming accounts that can accelerate doxxing chains.
