Believe Productions Listed by medusa Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Believe Productions Listed by medusa Ransomware Group (reported October 16, 2023) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
People connected to music education and industry programmes run by Believe Productions may have had internal company files taken in a ransomware incident claimed by the group known as medusa. Public reporting does not say how many individuals are involved or exactly which personal records, if any, sit inside those files, yet any exposure of workplace or programme data can create lasting practical problems for staff, partners, students, and families.
The listing appeared in mid-October 2023. Until the organisation or independent investigators release more detail, the safest course is to treat the claim seriously, understand what is known, and take basic steps to reduce follow-on risk.
Inside the incident
On 16 October 2023, Believe Productions was reported as listed by the medusa ransomware group. According to the available summary, the group claims that internal files were exfiltrated in a ransomware attack. The number of people affected remains unknown. No public timeline of the intrusion, no confirmed method of initial access, and no verified file counts or sample listings have been released beyond that high-level description. The incident is therefore known primarily through the group’s leak-site claim rather than through a detailed victim or law-enforcement confirmation.
Because the scale and precise contents have not been disclosed, it is not possible to state whether the taken material was limited to operational documents or also included contact lists, contracts, or other records tied to individuals. The only concrete assertion in the public record is that internal files were removed as part of the claimed attack.
Who is medusa?
Medusa is a ransomware operation that has been active in recent years and is documented for using double-extortion tactics: encrypting systems while also copying data and threatening to publish it if a ransom is not paid. The group maintains a leak site where it names organisations and, in many cases, posts samples or larger archives once deadlines pass. Like other ransomware crews, it typically gains entry through compromised credentials, unpatched remote services, or phishing, then moves laterally before deploying encryption and exfiltration tools. Public reporting on medusa has linked it to attacks across multiple sectors; its listings are claims until corroborated. In this case the group claims Believe Productions as a victim and asserts that internal files were taken; those assertions have not been independently verified in the material provided.
Who is Believe Productions?
Believe Productions is a company based in the Denver, Colorado area, founded in 1997. It describes its role as a link between music education and the music industry. Its main office is listed at 9540 Maroon Cir Unit 100, Englewood, Colorado, 80112, United States. Organisations of this type commonly handle programme schedules, instructor and student information, partnership agreements, billing or scholarship records, and internal correspondence. A breach affecting such an entity matters because the data it holds often connects young people, educators, working musicians, and commercial partners—groups that may not expect their details to circulate beyond the organisation’s own systems.
What data was at risk
The reported information states only that internal files were exfiltrated in a ransomware attack. No further breakdown of data types—such as names, contact details, financial records, or identification documents—has been disclosed. Organisations working at the intersection of education and the music industry typically maintain personnel files, participant rosters, contracts, and operational documents. Whether any of those categories were among the taken files is unconfirmed. Readers should therefore treat the exact contents as unknown while recognising that internal corporate material can still contain personal or sensitive information.
What's at stake
For individuals, the practical risks include unwanted contact, targeted phishing that references real programme or workplace details, and the possibility that contact or identity data could be reused in other fraud. Even when financial account numbers are not present, internal files can supply enough context to make social-engineering attempts more convincing. For the organisation, the stakes include operational disruption, potential regulatory or contractual notification duties, reputational harm among educators and industry partners, and the cost of investigation and recovery. Because the number of affected people is unknown and the file contents remain undisclosed, the full scope of downstream harm cannot yet be measured.
If your data was in this claimed breach
If you have worked with, studied under, or partnered with Believe Productions, treat the possibility of exposure as real until more detail emerges. Practical first steps include:
- Monitor email and phone communications for messages that reference music programmes, invoices, or internal project names you recognise; verify any request through a separate known channel before responding.
- Change passwords on accounts that may have been used in connection with the organisation, and enable multi-factor authentication where it is available.
- Review financial and credit statements for unfamiliar activity if you ever shared payment or identification details with the company.
- Be cautious of unexpected attachments or links, even from seemingly familiar addresses, because leaked internal correspondence can be weaponised for follow-on phishing.
- Consider running a free exposure scan of your email address to check whether it has already appeared in known breach data sets; such scans do not confirm involvement in this specific incident but can surface other exposures that warrant attention.
Public detail on this incident remains limited. Continue to watch for official statements from Believe Productions and treat any unsolicited “help desk” or ransom-related contact with scepticism. Calm, routine hygiene—strong unique passwords, multi-factor authentication, and careful verification of requests—remains the most reliable protection while the facts are still incomplete.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
