West Quay was listed on the leak site operated by the qilin ransomware group on December 09, 2025. The listing states that internal files were taken during a ransomware incident. No figure for the number of individuals affected has been released, and the organisation has not confirmed the claims or provided further details.

Inside the incident

The only confirmed public information is the appearance of West Quay on the qilin leak site. The group asserts that it obtained internal files through a ransomware operation. No date of the intrusion, volume of data, or method of access has been disclosed by either the organisation or the group. It remains unknown whether any data has been published or whether the organisation paid a ransom.

Inside qilin

Qilin is a ransomware-as-a-service operation that has been active since at least 2022. The group typically gains initial access through compromised credentials or remote-desktop services, then moves laterally inside networks before deploying encryption and exfiltrating data. It follows a double-extortion model, threatening to publish stolen material if a ransom is not paid. The group has previously claimed activity against organisations in manufacturing, logistics, and professional services, though each listing must be assessed individually.

Who is West Quay?

West Quay is a commercial organisation whose precise sector and size are not detailed in public breach records. Entities of this type commonly maintain records relating to customers, suppliers, employees, and internal operations. A compromise at such an organisation can expose both business information and personal data belonging to individuals who have interacted with it.

The information in question

The listing refers only to “internal files.” No inventory of specific data categories has been published. Organisations of this kind routinely hold contact details, financial records, employee information, and contractual documents. Without confirmation from West Quay or an independent forensic report, the exact contents of any exfiltrated material remain unconfirmed.

The real-world impact

Individuals whose information appears in the exfiltrated files could face risks of targeted phishing or identity misuse, depending on the nature of the data. For the organisation, the incident may result in regulatory scrutiny, costs associated with investigation and remediation, and potential loss of trust from customers and partners. The absence of a confirmed data count makes it difficult to quantify the scale of these risks at present.

Were you affected?

Check any communications you have received from West Quay regarding the incident. You can also run a free exposure scan of your email address against known breach datasets to see whether your information has appeared in previously published leaks. If you believe your data may be involved, monitor accounts for unusual activity and consider placing fraud alerts with credit agencies where applicable.

Publicly posted by qilin — 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. Recent Breaches and GalaxyWarden are independent and are not affiliated with, and do not endorse, any company or group named on this page.
