Comwave Listed by Medusa Ransomware Group

On May 17, 2024, Canadian telecommunications provider Comwave appeared on the leak site operated by the Medusa ransomware group. The listing states that internal files totaling 274.8 GB were exfiltrated during a ransomware attack. The company, which provides home internet, TV, and phone services to residential customers across Canada, has not yet published a formal breach notification detailing the exact records involved.

Details from the Medusa Listing

The Medusa leak site entry states that Comwave was hit by a ransomware deployment and that attackers successfully exfiltrated 274.8 GB of internal files before encryption. The disclosure does not specify the precise data types contained in the archive, nor does it list the number of customers or employees whose information was taken. It simply presents the stolen material as proof of compromise and sets an implicit deadline for payment before further publication. The corporate headquarters address at 61 Wildcat Rd, Toronto, Ontario, is also referenced, matching publicly available company information.

Why This Matters for You and Your Family

If you are a Comwave customer, your personal details may sit inside the 274.8 GB archive now controlled by Medusa. Residential internet, television, and voice-service providers routinely store names, service addresses, phone numbers, account credentials, payment methods, and sometimes government-issued identification used for credit checks. Even without an exact customer count, the exposure of internal files at this scale means household information linked to your home internet connection is now in criminal hands. That data can be sold, used for identity theft, or leveraged to impersonate you with other utilities or financial institutions.

Doxxing and Identity-Chain Risks

A single leaked internet-service record quickly becomes a pivot point for larger doxxing campaigns. Attackers cross-reference your service address with public records, social-media handles, and email addresses to build a complete profile. Once they control even one of your accounts, they can reset passwords elsewhere, request SIM swaps, or publish your family’s details on underground forums. Children’s accounts are especially vulnerable because gaming usernames and parental email addresses often share the same household address or phone number listed with Comwave. These credential leaks cascade into account takeovers that expose chat logs, location data, and photos far beyond the original breach.

Medusa’s Known Track Record

Public reporting attributes Medusa’s first notable campaigns to late 2021. The group has since targeted organizations across North America and Europe, frequently listing healthcare providers, manufacturers, and technology-service firms. Their standard playbook involves initial access through phishing or exploited remote-desktop services, followed by extensive internal reconnaissance, data exfiltration, and then dual extortion: demanding ransom to prevent file encryption and a second payment to stop data publication. The Medusa leak site typically posts samples and countdown timers, increasing pressure on victims who have not paid. The Comwave listing follows this pattern exactly.

What to do

• Run a DoxxScan to map every link between your email, phone number, service address, and online handles so you can see the full exposure chain created by this claimed breach.
• Rotate any password you used for your Comwave account and enable 2FA with an authenticator app on every service where that password was reused.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours rather than months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts tied to the same residential address now listed in the Medusa archive.
• Let remediation specialists handle data-broker takedown requests and opt-out processes that would otherwise require weeks of manual effort.

The Medusa listing of Comwave is a concrete reminder that even established Canadian service providers remain targets and that your household data can surface with little warning. Starting proactive defense now limits how far attackers can travel down the identity chain. 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 family coverage that includes children’s gaming accounts at risk from credential leaks like this one.
