Zenithpharma targeted by meow ransomware group

• Ransomware group: meow
• Country: Morocco
• Sector: Healthcare
• Announcement date: November 24, 2023

The threat actor known as meow has published data allegedly belonging to Zenithpharma on its leak site. This announcement, made by the group, marks a new addition to their list of victims, involving a company operating within the healthcare sector.

The claims made by meow

The meow group announced the addition of Zenithpharma to its leak list on November 24, 2023. According to the threat actor, the attack occurred around November 5, 2023. The group claims that approximately 15% of the organization's data has been leaked as a result of the incident. The post provided by the attackers includes a list of file names that allegedly belong to the organization's databases, accompanied by a download link for the purported data.

Ransomware leak sites like the one used by meow are a central component of modern cyberattacks. In these scenarios, threat actors often employ a tactic known as double extortion. In a double extortion scheme, attackers do not merely encrypt an organization's systems to disrupt operations; they also exfiltrate sensitive data before the encryption process begins. The threat of leaking this stolen information on a public or semi-public leak site serves as additional leverage to pressure the victim into paying a ransom. By threatening to release confidential files, the attackers aim to maximize the impact of the breach on the organization's reputation and legal standing.

Data allegedly involved in the leak

Based on the screenshot provided in the announcement, several types of sensitive information are allegedly included in the leak. The data purportedly stolen from Zenithpharma includes various critical system components and databases. The specific items mentioned in the leak claim include:

• CRM databases
• WordPress content management system data
• System schemas (including mysql, performance_schema, and glpi2021)

The presence of such diverse data types suggests a broad reach within the victim's network. When attackers target content management systems like WordPress or core database schemas, they often gain access to the structural backbone of an organization's digital presence. This can expose not just the content itself, but the underlying architecture used to manage it.

Implications and industry considerations

This leak claim may pose a risk to the organization's operational continuity and the confidentiality of its customer data. The CRM and database files allegedly leaked could contain trade secrets or patient/customer information. Such a breach can have significant consequences for a healthcare entity, as the integrity and privacy of medical and personal information are paramount in this sector. Furthermore, the use of leaked data in secondary attacks or phishing campaigns remains a possibility, as stolen credentials or organizational details are often repurposed by other threat actors.

For organizations operating in the healthcare sector, such incidents can lead to significant compliance issues under data protection regulations in Morocco, where the organization operates. Regulatory bodies often require strict adherence to protocols regarding the handling and protection of sensitive personal and medical data. A confirmed breach can trigger mandatory notification requirements and potential legal scrutiny.

To mitigate the risks associated with such threats, organizations typically focus on several defensive layers. Implementing robust, multi-factor authentication (MFA) across all systems can help prevent unauthorized access. Regular, offline backups are essential for maintaining operational continuity in the event of a ransomware infection. Additionally, maintaining strict network segmentation can prevent an attacker from moving laterally from a single compromised system to critical databases like CRM or WordPress installations. Finally, continuous monitoring and rapid incident response capabilities are vital for detecting and containing a breach before significant data exfiltration occurs.

Public information regarding the meow group remains limited, making it difficult to attribute the attack to a specific known entity or to predict their future tactics with certainty.
