Nova ransomware group claims data breach at Pere Claver grup

The ransomware group known as Nova has claimed responsibility for a data breach involving the Spanish organization Pere Claver grup. According to an announcement made on a leak site, the group asserts that they have exfiltrated and published data belonging to the entity.

Details of the alleged attack

Based on the information provided in the group's post, the cyberattack against Pere Claver grup involved the encryption of the organization's systems. The group claims that this encryption occurred on March 28, 2025. Following the initial attack, the group announced that the stolen data was made available on their leak site on April 15, 2025. The announcement regarding this specific incident was officially posted on the leak site on April 28, 2025.

Information regarding the Nova group remains limited in the public domain. In modern cybercrime, ransomware groups often employ a tactic known as double extortion. In these scenarios, attackers do not merely encrypt an organization's files to disrupt operations; they also steal sensitive data beforehand. The threat of leaking this stolen information on a public leak site serves as additional leverage to pressure the victim into paying a ransom. While the specific details of the Nova group's operations are not widely documented, their actions follow this common pattern of extortion.

Data involved in the leak

The group has provided very limited details regarding the specific content of the information they claim to have stolen. The listing does not specify any particular types of data or files that were compromised. The only information provided regarding the scope of the breach is the total size of the data, which is stated to be 5 GB.

• Data size: 5 GB

Because the group has not provided a detailed inventory of the files, the exact nature of the information remains unknown.

Organization profile

Pere Claver grup is a social services organization based in Barcelona, Spain. The entity provides essential support to individuals at risk of social exclusion and those experiencing mental health issues. Their operational scope includes various programs focused on the fields of education, employment, and social integration.

Impact and potential consequences

The alleged leak may lead to the exposure of corporate data within Pere Claver grup. Because the organization operates within Spain, it is subject to strict regulatory frameworks. Consequently, the entity could face administrative sanctions under GDPR regulations due to the potential exposure of sensitive information. If the leaked data includes employee or customer information, it may create secondary risks for individuals, such as identity theft or targeted phishing attacks.

Given the organization's presence in the professional services sector, this incident could impact its supply chain and lead to reputational damage. Furthermore, the publication of the data may be considered a factor that could affect the organization's operational continuity. When organizations face such breaches, common defensive and recovery steps often include implementing robust backup strategies, enhancing endpoint detection and response capabilities, and conducting thorough forensic investigations to determine the extent of the compromise.
