Blacknevas claims to have compromised Payme Ltd
The threat actor group known as Blacknevas has announced on its leak site that it has compromised a significant amount of data belonging to Payme Ltd. According to the claims made by the group, the breach involves approximately 1030 GB of data. The announcement regarding this alleged data leak was posted on August 6, 2025.
Ransomware groups often utilize leak sites to pressure organizations into paying ransoms through a tactic known as double extortion. In such scenarios, attackers not only encrypt an organization's systems but also steal sensitive information, threatening to publish it publicly if their demands are not met. This method increases the pressure on companies due to the potential for regulatory scrutiny and reputational damage following a public disclosure of stolen data.
Details of the alleged attack
The Blacknevas group claims to have gained access to the entire infrastructure of Payme Ltd. According to the group's announcement, the alleged breach occurred on May 24, 2025. While the group has claimed responsibility for the intrusion and the subsequent data theft, information regarding the specific identity and background of this group remains limited in the public domain.
The group's announcement indicates that the stolen information is substantial in volume, totaling 1030 GB of data extracted from the corporate infrastructure. The nature of the breach suggests a deep level of access, as the attackers claim to have penetrated the core systems of the organization.
Affected data types
- Passport data
- Financial reports
The claim specifies that the data involved in this alleged breach includes sensitive documentation such as passport data and various financial reports.

The firm specializes in providing payroll and contracting management services designed for agencies and contractors.

Potential impact and industry considerations
The claims made by Blacknevas regarding the theft of passport data and financial reports could pose significant risks to the organization's employees and clients. Specifically, such data can be utilized for identity theft and financial fraud. Furthermore, because the company operates within the United Kingdom, it may be required to address specific data protection obligations under the UK GDPR framework following such an incident.
The nature of the allegedly leaked data could also create secondary risks for the company's supply chain partners, who may rely on the integrity of the data handled by Payme Ltd. Given that the company operates in the professional services sector, an incident of this nature may potentially lead to significant reputational damage and the possibility of regulatory penalties.
For organizations operating in similar professional services sectors, maintaining robust defensive measures is critical. Common defensive steps include implementing multi-factor authentication, maintaining rigorous patch management schedules, and conducting regular security awareness training for staff. Additionally, organizations often focus on data encryption and network segmentation to limit the potential movement of an attacker within the infrastructure and to mitigate the impact of a successful breach.
