Everest ransomware group claims data breach against Watchfinder & Co

The Everest ransomware group has officially listed the United Kingdom-based retailer Watchfinder & Co on its dedicated leak site. Through this announcement, the threat actor group has made claims regarding a data breach involving the organization. This development is part of the ongoing pattern of leak activities conducted by the Everest group on their platform.

Details of the alleged attack

According to the announcement published on the group's leak site, the incident is tied to an event that allegedly occurred on July 21, 2025. The Everest group claims to have successfully gained unauthorized access to the internal systems of Watchfinder & Co. By penetrating these systems, the group asserts that they have obtained data belonging to the organization.

The listing was officially announced on the leak site on July 23, 2025. It is important to note that the group's methods often involve double extortion, a tactic where attackers not only encrypt an organization's data to disrupt operations but also steal sensitive information to use as leverage. In such scenarios, the threat actors threaten to publish the stolen data on public leak sites if a ransom is not paid, thereby exerting pressure through the threat of reputational damage and regulatory scrutiny.

Information regarding the stolen data

While the Everest group has claimed to have obtained data from the organization, they have not provided specific details regarding the nature of the information allegedly leaked. The listing does not include any sample files or specific descriptions of the data types that were targeted during the breach. Consequently, the exact scope and content of the alleged theft remain unknown at this time.

About Watchfinder & Co

Watchfinder & Co. is a prominent retailer based in the United Kingdom. The company specializes in the buying and selling of pre-owned luxury watches. They provide a wide range of certified pre-owned models from numerous prestigious watch brands from across the globe, catering to a high-end consumer market.

Potential risks and organizational impact

The claims made by the Everest group present several significant risks to the organization. Given the past activities associated with the Everest group, there is a distinct possibility that the organization's sensitive data could be leaked to the public or utilized for extortion purposes. Such an outcome could lead to various secondary risks, including the potential for identity theft or the execution of targeted phishing attacks against the organization's customers and employees.

Furthermore, because Watchfinder & Co is based in the United Kingdom, any confirmed data breach involving personal information may fall under the scope of the UK General Data Protection Regulation (UK GDPR). This could potentially expose the company to legal sanctions and regulatory investigations. The group's typical methods, which include both data theft and the selling of access, can severely impact an organization's operational continuity and its overall reputation in the marketplace.

For organizations operating in the retail and e-commerce sectors, maintaining robust cybersecurity postures is essential to mitigate these types of threats. Common defensive strategies include implementing multi-factor authentication, maintaining rigorous patch management schedules, and conducting regular security awareness training for employees to recognize phishing attempts. Additionally, maintaining comprehensive backups and ensuring data encryption can help protect sensitive information from being easily exploited if a perimeter is breached.
