Ontario West and Bill Blaney Insurance Brokers Listed by Medusa Ransomware Group

Ontario West and Bill Blaney Insurance Brokers were listed on the Medusa ransomware group’s leak site on June 27, 2024. The Canadian insurance brokerage, which has served Southwestern Ontario since 1987, is the latest victim claimed in the gang’s ongoing extortion campaign. Anyone who has purchased insurance through the firm, provided personal information for a policy, or had their claims processed there may have had sensitive files exposed.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

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 580 companies.

Primary Disclosure Details

The Medusa leak site states that internal files were exfiltrated during a ransomware attack and that 109.3 GB of data has been obtained. The listing does not specify the exact types of records taken, nor does it quantify how many individuals are affected. It simply states that Ontario West and Bill Blaney Insurance Brokers, located at 1069 Wellington Rd Ste 208, London, Ontario, were compromised and that the stolen material is now available for download by anyone who pays the extortion fee. The disclosure indicates the data was taken from corporate systems but provides no further technical breakdown of the breach method or timeline.

Why This Matters for You and Your Family

If you hold an insurance policy through Ontario West or Bill Blaney, your name, address, date of birth, driver’s licence number, medical details tied to claims, banking information for premium payments, and policy documents may sit inside the 109.3 GB archive. Insurance records are especially dangerous because they combine financial data with health information and government identifiers in one convenient package. Once that combination leaves the broker’s control, it can fuel identity theft, fraudulent loan applications, or targeted scams that reference your real policies. Even if you are not a current customer, family members or dependents listed on joint policies could be exposed without your knowledge.

Doxxing and Identity-Chain Risks

Insurance data rarely stays isolated. A single leaked policy file often contains email addresses, phone numbers, and home addresses that attackers can cross-reference with other breaches. This creates long identity chains that link your professional life, family relationships, and online handles. Credential leaks like this one frequently cascade into account takeovers on banking portals, government services, and especially gaming accounts belonging to you or your children. A teenager’s username and reused password harvested from a family insurance record can lead to doxxing that reveals the entire household’s physical location. The longer these chains remain unmapped, the higher the chance that one breach becomes dozens of targeted attacks.

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.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
