Clarkson Insurance Group Listed by medusa Ransomware Group

On November 20, 2024, Clarkson Insurance Group, an insurance broker serving businesses, families, and private individuals in Louisville, Kentucky, was listed on the Medusa ransomware group’s leak site. The listing states that attackers exfiltrated 115.9 GB of internal files during a ransomware incident. The company has not yet issued a public notification detailing the exact records involved, leaving affected customers and employees uncertain about their specific exposure.

Details from the Leak-Site Listing

The Medusa leak site entry states that Clarkson Insurance Group suffered a ransomware attack in which internal files were taken before encryption. The disclosure indicates 115.9 GB of data were exfiltrated, though it does not specify the precise data types or the number of individuals whose information was included. Public views of the listing, archived via ransomware.live at the onion address provided, show sample files but do not quantify affected customer or employee records. As of the publication date, Clarkson Insurance Group has made no formal regulatory filing or customer notification that discloses additional details.

Why This Matters for You and Your Family

If you or your family hold an insurance policy brokered by Clarkson Insurance Group, your personal information may sit inside the stolen files. Insurance records routinely contain names, addresses, dates of birth, Social Security numbers, driver’s license details, policy numbers, and financial payment information. Exposure of this data increases the chance of identity theft, fraudulent loan applications, and targeted phishing campaigns that reference your actual policies. Even without an exact victim count, the 115.9 GB volume suggests a substantial portion of the company’s customer and operational data was taken.

Doxxing and Identity-Chain Risks

Stolen insurance documents often link your real identity to email addresses, phone numbers, policy beneficiary details, and sometimes spouse or children’s information. Attackers and subsequent data resellers can chain these records with usernames found in other breaches, creating detailed profiles used for doxxing, SIM-swapping, or account takeovers. Gaming accounts belonging to children are particularly vulnerable because the same email or password reused for a family insurance portal can unlock Steam, Roblox, or Epic profiles, exposing chat logs, payment methods, and friend networks that further expand the identity chain.

Medusa Ransomware Group’s Track Record

Public reporting attributes Medusa’s emergence to mid-2021. The group operates a double-extortion model: it encrypts victim systems and simultaneously exfiltrates data, then demands payment to prevent publication. Notable prior victims include healthcare providers, manufacturers, and professional-services firms. Typical Medusa playbooks begin with compromised credentials or vulnerable remote-desktop services, followed by lateral movement, data archiving, and eventual posting on their leak site with countdown timers if ransom is not paid. The Clarkson Insurance Group listing follows this established pattern.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity drawn from this and prior exposures.
• Rotate any password you used on the Clarkson Insurance Group portal or related broker sites, 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 leak exposing you or your family is caught and acted on quickly.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts vulnerable to credential-cascading takeovers.
• Let remediation specialists handle data-broker takedown requests and opt-out processes that would otherwise require months of individual effort.

The incident underscores that insurance providers remain high-value targets whose breaches directly expose the personal and financial lives of ordinary families. Starting proactive defense now limits how far attackers can travel down the identity chain created by this and future leaks. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts at risk from cascading credential abuse.
