gproulxinc.com Listed by lockbit3 Ransomware Group

On March 21, 2023, construction supplier G. Proulx Inc. appeared on the LockBit 3.0 ransomware leak site, claiming that the Montreal-area company had been hit by a ransomware attack in which internal files were exfiltrated.

Details from the Leak Site

The primary disclosure on the LockBit 3.0 portal states that attackers successfully breached gproulxinc.com and removed internal files. The listing does not specify the volume of data taken, the exact types of records involved, or any ransom amount demanded. It simply states that exfiltration occurred during a ransomware incident and that the company now faces public exposure of those files if payment is not made. G. Proulx Inc., which has supplied commercial, industrial, institutional and residential construction materials in the Montreal region for more than 45 years, has not released a separate public notification quantifying affected records or naming the precise systems compromised.

LockBit 3.0 published the entry on its leak site, following its standard practice of first encrypting victim networks, exfiltrating data, then threatening to publish it unless a ransom is paid.

Why This Matters for You and Your Family

When a local business like a construction supplier is breached, the people whose information ends up in the stolen files are often customers, vendors, employees and their families. Even though the leak-site listing does not detail what was taken, construction-company records frequently contain names, addresses, phone numbers, email addresses, payment information, employee tax documents, contracts, and project files that can reveal where people live and work. Once that information leaves the company’s control, it can be used for identity theft, phishing campaigns, or sold quietly on other underground forums. Your family’s exposure does not require you to have been the direct target; it only requires that one of your details was stored in the files LockBit 3.0 now controls.

Doxxing and Identity-Chain Risks

Stolen internal files rarely stay isolated. A single email address or phone number from a construction supplier’s records can be combined with other publicly available data to map out your full digital footprint. Attackers chain these fragments together: an email from a vendor list links to your social-media accounts, a home address in a delivery record reveals your physical location, and a child’s name on a family account can expose gaming profiles. This identity-chain effect turns one breach into long-term doxxing risk, where harassers, identity thieves or even burglars gain a clear picture of your household. Credential leaks of this kind also cascade into account takeovers, especially for gaming accounts belonging to you or your children that reuse the same passwords or recovery emails.

LockBit 3.0’s Known Track Record

Public reporting attributes the LockBit ransomware group’s initial emergence to 2019. It rebranded as LockBit 2.0 in 2021 and then as LockBit 3.0 in 2022. The gang has targeted organizations across dozens of countries and sectors, from healthcare providers to manufacturers and local governments. Their typical playbook involves gaining initial access through phishing, remote-desktop vulnerabilities or stolen credentials, deploying ransomware to encrypt systems, exfiltrating sensitive files beforehand, and then pressuring victims with both encryption and the threat of data leaks on their public site. LockBit 3.0 is known for aggressive extortion tactics, including countdown clocks and selective publication of stolen documents to increase pressure.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by specialists.
• Rotate any password you used at gproulxinc.com or related vendor portals anywhere it has been reused, and immediately enable 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ 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 that often chain back to the same addresses and emails.
• Let remediation specialists perform hands-on takedown requests across data brokers and leak sites on your behalf instead of attempting it alone.

The incident underscores that ransomware groups continue to target ordinary regional businesses, and the data they steal can affect anyone whose information was stored there. A forward-looking approach means treating every new breach as a signal to lock down your personal exposure before criminals connect the next dot. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage including children’s gaming accounts.
