Hammersmith Medicines Research Listed by maze Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Hammersmith Medicines Research Listed by maze Ransomware Group (reported March 14, 2020) 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.
What happened
The only confirmed information is the appearance of Hammersmith Medicines Research on the Maze leak site. The group claims to have stolen internal data in the course of a ransomware attack. No statement from the organisation, no figure for records or individuals involved, and no description of how access was obtained have been released.
Inside maze
Maze is a ransomware operation that emerged in 2019 and became known for combining file encryption with the theft and threatened publication of data. The group maintains a site where it lists organisations that have not met its demands, posting samples or descriptions of material it says was removed. This approach, sometimes called double extortion, has been documented across multiple incidents involving the same actor.
Hammersmith Medicines Research and its sector
Hammersmith Medicines Research conducts clinical trials and related medical studies. Organisations of this type routinely process records that include participant information, study protocols, laboratory results and correspondence with sponsors and regulators. A breach at such a facility therefore touches both operational documents and material that can contain personal and health-related details.
The information in question
The listing refers only to “internal files.” No inventory of data types, file counts or time periods has been published by either the group or the organisation. While clinical-research entities commonly hold patient identifiers, consent forms, trial data and regulatory submissions, the precise contents taken in this case remain unconfirmed.
The real-world impact
Exposure of internal research files can create privacy risks for trial participants and may affect the confidentiality of ongoing studies. For the organisation, the incident adds the possibility of regulatory scrutiny and operational disruption. Without a confirmed list of affected records, the scale of these consequences cannot yet be measured.
What to do if you're exposed
Individuals who believe their information may have been involved should monitor statements from Hammersmith Medicines Research and any official notifications issued by regulators. Basic steps include changing passwords on any linked accounts, enabling multi-factor authentication, and watching for unusual activity on financial or medical records. Readers can also run a free exposure scan of their email address against known breach data to check for prior appearances in public listings.

Publicly posted by maze — unverified claim, pending independent verification
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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
