— from Medusalocker’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.
INSULCANA CONTRACTING LTD Listed by medusalocker Ransomware Group

On July 27, 2023, Canadian construction firm Insulcana Contracting Ltd appeared on the leak site operated by the medusalocker ransomware group. The listing states that internal files were exfiltrated during a ransomware attack and offers them for sale at a $35,000 price. The disclosure indicates that the stolen material includes employee information, agreements, customer emails in .xls format, Canadian passports, and other unspecified documents. The number of people whose records were taken remains unknown.

Primary Disclosure Details

The medusalocker leak site entry, archived via ransomware.live at the onion address provided, explicitly lists Insulcana Contracting Ltd as a victim and describes the data as “employee information – agreement – customer email(.xls)- passport all canada and other documents.” No exact record count is published, nor does the listing specify the initial intrusion vector or the precise date the files were taken. The group demands $35,000 for the alleged archive and threatens to publish or sell the material if unpaid. Public reporting on medusalocker indicates this pricing and partial-file-preview format is consistent with their standard extortion approach.

Why This Matters for You and Your Family

When a company that handles employment records, customer lists, or identity documents is breached, the exposure reaches far beyond corporate walls. If you or any member of your family ever worked with, contracted through, or provided personal details to Insulcana Contracting Ltd, your information may now sit inside a ransomware operator’s archive. Canadian passports, employee files, and customer spreadsheets are high-value items on underground markets because they combine real names, dates of birth, addresses, and government identifiers in one package. Even if you are not certain whether your data was involved, the uncertainty itself creates risk: fraudsters test leaked credentials across multiple services hoping for reuse.

Doxxing and Identity-Chain Implications

Ransomware groups rarely stop at simple credential dumps. Once employee or customer spreadsheets leave the victim’s network, they frequently appear in doxxing chains that link workplace emails to personal accounts, home addresses, and family members. A single .xls row containing your name, phone number, and passport details can be cross-referenced with gaming usernames, social-media handles, or children’s school records. These linkages allow attackers to escalate from identity theft to targeted extortion, account takeovers, or physical threats. Credential leaks of this nature routinely cascade into gaming-account compromises because the same email and password combinations are used for Steam, Epic, Roblox, or other platforms popular with children and teenagers.

MedusaLocker’s Known Track Record

Public reporting attributes the first appearances of medusalocker to late 2021. The group has since claimed responsibility for attacks on healthcare providers, manufacturers, and construction firms across North America and Europe. Their typical playbook begins with phishing or exploitation of remote-desktop services for initial access, followed by deployment of encryption software and exfiltration of sensitive files before triggering the ransomware. After encryption they wait a short period, then publish samples on their leak site and demand payment in bitcoin. The Insulcana Contracting Ltd listing follows this pattern exactly: partial samples are shown, a fixed dollar price is set, and a publication deadline is implied though not always stated explicitly.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with no-subscription cleanup handled by the service.
  • Rotate any password you ever used at Insulcana Contracting Ltd or related systems, then 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 surfaces in hours instead of months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same breached address or email.
  • Let remediation specialists manage takedown requests for any exposed documents or personal listings that appear on data-broker or extortion sites.

The incident underscores that construction and contracting firms are now routine targets; any business that stores Canadian identity documents or employee spreadsheets can become an unwitting gateway to your family’s personal risk. Start your DoxxScan trial today and gain both continuous monitoring and hands-on assistance that ordinary breach-notification letters cannot provide. DoxxScan’s AI-powered identity-chain mapping and specialist remediation team give you a practical defense against the cascading threats that follow ransomware leaks like this one.

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.
