high severity April 05, 2024 · 3 min read Unverified claim — what this is

Solano County Library Listed by Medusa Ransomware Group

If you are a resident of Solano County Library, here’s what is being claimed, and what it would mean for you.

The Solano County Library is a public library system serving the cities of Dixon, Fairfield, Rio Vista, Suisun City, Vacaville and Vallejo, California. The Solano County Library was established in 1914 by the county's board of supervisors. Solano County Library corporate office is located in 601 Pintail Dr 763, Suisun City, California, 94585, United States and has 67 employees. The total amount of data leakage is 85.02 GB
— from Medusa’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.

Solano County Library Listed by Medusa Ransomware Group

On April 5, 2024, the Solano County Library appeared on the leak site operated by the medusa ransomware group. The listing states that internal files totaling 85.02 GB were exfiltrated during a ransomware attack on the public library system serving Dixon, Fairfield, Rio Vista, Suisun City, Vacaville, and Vallejo, California. The disclosure does not specify the exact number of people affected or list the precise categories of records involved.

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.

Details from the Leak-Site Listing

The medusa leak site entry states the library was hit by a ransomware deployment and that attackers successfully removed 85.02 GB of internal files. No sample data is shown publicly, and the listing does not quantify how many customer records, staff files, or patron databases were taken. The Solano County Library, established in 1914 and headquartered at 601 Pintail Drive in Suisun City, has not yet released its own public notification detailing the breach scope. As is common with these listings, the group sets a deadline for payment before threatening full publication of the stolen archive.

Why This Matters for You and Your Family

If you or your family hold a library card in any of the six cities served by Solano County Library, your personal information may be inside the stolen material. Public libraries routinely store names, addresses, phone numbers, email addresses, library card numbers, and sometimes driver’s license details or children’s reading histories. When 85 GB of internal files leave a county system, the exposure can reach far beyond simple checkout records. Staff personnel files, vendor contracts, and internal correspondence are also likely included, increasing the chance that someone’s home address, date of birth, or Social Security number is now in criminal hands.

The Doxxing and Identity-Chain Risk

Ransomware operators rarely stop at one database. A single leaked email or phone number from this claimed breach can be combined with information from earlier exposures to build a complete identity profile. Attackers chain these fragments across dozens of platforms, linking your library account to gaming usernames, social-media handles, and family-member profiles. The result is doxxing that can lead to targeted phishing, account takeovers, or even physical harassment. Credential leaks of this type frequently cascade into children’s gaming accounts that share the same household email or password patterns.

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.
