— from Alphv’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
COEX Listed by alphv Ransomware Group

On June 20, 2023, the architectural firm Barin Architects of Montreal appeared on the leak site of the alphv ransomware group. The listing states that internal files were exfiltrated during a ransomware attack. The number of records affected and the precise data types remain undisclosed in the primary listing.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

Reported Details from the Leak

The alphv leak site entry, still accessible via the .onion link tracked by ransomware.live, identifies the victim as Barin Architects and claims successful data theft. It does not quantify the volume of material taken or list specific categories such as client contracts, employee records, or financial documents. The disclosure indicates that the files were stolen as part of a double-extortion operation in which the group first encrypts systems and then threatens to publish the stolen data unless a ransom is paid. No ransom amount or payment deadline is shown in the current posting.

Why This Matters for You and Your Family

When an architecture firm like Barin Architects is hit, the people whose information sits in those internal files face direct risk. Clients, contractors, employees, and anyone whose personal details were stored in project folders or HR systems may now be exposed. Internal files exfiltrated often contain names, addresses, phone numbers, email accounts, dates of birth, and sometimes financial or insurance information. Even without an exact record count, the exposure is real: once data leaves the company’s control it can be traded, sold, or used to target you or your family with phishing, identity theft, or harassment. Ordinary families who hired the firm for home renovations, office builds, or community projects are just as affected as the business itself.

The Doxxing and Identity-Chain Risk

Stolen internal files frequently create long identity chains. An email address found in one document can be linked to accounts on other services; a home address tied to a renovation project can be cross-referenced with public records and social-media profiles. These chains allow attackers to build detailed dossiers that lead to doxxing, account takeovers, or spear-phishing campaigns against you and your children. Credential leaks of this nature routinely cascade into gaming accounts, where stolen passwords grant entry to platforms that store chat logs, payment methods, and friend networks. The result is a widening circle of exposure that can touch every member of the household.

Alphv’s Known Track Record

Public reporting attributes the alphv group, also known as BlackCat, with emerging in late 2021. The gang has since claimed responsibility for attacks on hundreds of organizations across North America, Europe, and Australia. Notable prior victims include large healthcare providers, manufacturing companies, and professional-services firms. Their standard playbook involves gaining initial access through phishing, remote-desktop compromise, or stolen credentials, followed by rapid lateral movement, data exfiltration, and deployment of custom ransomware. They operate a ransomware-as-a-service model that lets affiliates use their tools while the core group maintains the leak site and handles negotiations. Extortion tactics typically combine encryption with public shaming on the dark-web portal, applying pressure through countdown clocks and sample-file releases.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup to shrink your exposure footprint.
  • Rotate any password you ever used at Barin Architects wherever it has been reused, and switch on two-factor authentication through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours instead of 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 after credential leaks like this one.
  • Let remediation specialists handle takedown requests for any personal data already appearing on broker sites or forums tied to the incident.

The alphv listing is a concrete reminder that even mid-sized professional firms hold data that can harm ordinary families long after the initial breach. Taking deliberate steps now limits how far that harm can travel. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with household coverage that includes children’s gaming accounts vulnerable to credential-based takeovers.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
