SimonMed Imaging Listed by medusa Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Healthcare providers remain frequent targets in the ransomware landscape, where attackers seek both operational disruption and the leverage of sensitive clinical and administrative records. Against that backdrop, SimonMed Imaging appeared on a listing associated with the medusa ransomware group, according to public reporting dated January 27, 2025. The listing claims that internal files were exfiltrated and that the volume of data involved reached 212.616 GB. The number of people affected has not been disclosed.

For patients, staff and partners of an outpatient imaging network, any confirmed or claimed compromise of internal systems raises practical questions about what information may have left the organisation and what steps follow. Public detail remains limited to the group’s claim and the organisational facts already known; this article sets out only what has been reported and the established context around the actor and the sector.

Breaking down the breach

According to the reported summary, SimonMed Imaging was listed by the medusa ransomware group on or around January 27, 2025. The listing asserts that internal files were exfiltrated in a ransomware attack and that the total volume of data leakage is 212.616 GB. No further technical detail—such as the initial access method, the duration of unauthorised presence, or confirmation of encryption—has been made public in the available record. The number of individuals whose information may be involved is listed as unknown.

Because the primary source of the claim is the threat actor’s own leak-site listing, the incident should be treated as an unverified assertion until independently confirmed by the organisation or by regulators. No dollar amounts, specific file names, or patient counts appear in the facts provided. The organisation’s size—approximately 2,030 employees and more than 150 accredited facilities—indicates a substantial operational footprint, but does not by itself establish the scope of any compromise.

Inside medusa

Medusa is a ransomware operation that has been publicly documented for several years. Like many contemporary groups, it typically employs a double-extortion model: encrypting systems while also copying data and threatening to publish or sell it if a ransom is not paid. The group maintains a leak site on which it posts victim names, sample files and claimed data volumes as pressure tactics. Listings are therefore claims made by the attackers themselves and do not constitute independent verification that a breach occurred or that the stated volume is accurate.

Public reporting on medusa has described the use of common initial-access vectors such as phishing, exploitation of exposed remote-access services, and compromised credentials, followed by lateral movement and data staging before encryption. The group has previously listed organisations across healthcare, manufacturing and professional services. None of those general patterns should be read as What's Publicly Reported about the SimonMed Imaging incident; they simply describe the actor’s established public profile.

About SimonMed Imaging

SimonMed Imaging is an outpatient medical imaging provider founded in 2003. It operates across the United States with more than 150 accredited facilities that are ACR-RADSITE certified and staffed by certified technologists using certified equipment. Its corporate office is located at 16220 N Scottsdale Rd Ste 600, Scottsdale, Arizona 85254, and the organisation employs approximately 2,030 people.

As a diagnostic imaging network, SimonMed handles referral orders, imaging studies, reports and the administrative data required to schedule, bill and communicate results. Such organisations routinely process protected health information under U.S. healthcare privacy rules, along with employee and vendor records. A claimed ransomware incident therefore carries consequences beyond pure IT disruption: it can affect clinical continuity, patient trust and regulatory obligations even when the precise contents of any exfiltrated material remain unconfirmed.

What data was at risk

The available facts state only that “internal files” were exfiltrated in a ransomware attack and that the claimed volume is 212.616 GB. No specific data categories—such as patient names, medical record numbers, imaging reports, Social Security numbers, payment card details or employee records—have been named as confirmed exposures. Public detail on the exact contents is therefore limited.

Organisations of this type typically hold imaging studies and associated reports, demographic and insurance information, scheduling data, and internal administrative files. Whether any of those categories were among the claimed 212.616 GB cannot be established from the current record. Readers should treat any assertion of particular data types as unconfirmed until the organisation or an official investigation provides further clarity.

What's at stake

For individuals, the principal risks associated with a healthcare-related ransomware claim are identity theft, medical identity fraud and unwanted contact if contact details or clinical information were among the files taken. Even when the precise contents are unknown, the mere possibility that internal files left the organisation warrants heightened monitoring of credit reports, explanation-of-benefits statements and any unexpected medical bills. For the organisation, stakes include operational recovery costs, potential regulatory scrutiny under health-privacy rules, contractual obligations to partners, and reputational impact with referring physicians and patients.

Because the number of people affected remains unknown and the data types have not been itemised, it is not possible to quantify individual exposure. The claimed volume of 212.616 GB is large enough to encompass substantial internal material, yet volume alone does not prove that any particular person’s record was included. Calm verification and routine protective steps remain the proportionate response.

If your data was in this claimed breach

If you are a patient, employee or partner of SimonMed Imaging and are concerned that your information may have been involved, the following practical steps are advisable:

• Monitor financial and medical statements for unfamiliar activity and request free credit reports from the major bureaus.
• Consider placing a fraud alert or credit freeze if you see signs of misuse.
• Review any notices the organisation may issue and follow official guidance rather than unverified social-media claims.
• Change passwords on accounts that reuse credentials associated with the organisation and enable multi-factor authentication where available.
• Run a free exposure scan of your email address to check whether it has already appeared in other known breach data sets.

Public information about this incident is limited to the medusa group’s listing, the reported date of January 27, 2025, the claimed exfiltration of internal files totalling 212.616 GB, and the organisational background already stated. Further Reported Details, if any, will come from the organisation itself or from regulatory disclosures. Until then, treat the listing as an unverified claim and take the ordinary precautions that apply after any potential healthcare data exposure.
