Luna Group data allegedly leaked by Lamashtu ransomware group

• Ransomware group: Lamashtu
• Country: Egypt
• Sector: Manufacturing
• Announcement date: May 4, 2026

The Lamashtu ransomware group has listed a significant amount of data allegedly belonging to the Egyptian conglomerate Luna Group on their dedicated leak site. According to the announcement made on May 4, 2026, the threat actor claims to have exfiltrated a substantial volume of sensitive information from the organization.

The claimed attack and data exfiltration

The Lamashtu group claims to have successfully compromised data belonging to Luna Group and has subsequently published a leak announcement. The group alleges that the breach involved the theft of approximately 35 GB of data, consisting of roughly 40,000 files. These files reportedly span a time period ranging from 2023 to 2026.

According to the claims made by the attackers, the stolen information was obtained directly from an internal file server belonging to the organization. This method of exfiltration is common in modern ransomware attacks, where actors target centralized storage systems to maximize the volume of sensitive data collected during the intrusion phase.

Details of the allegedly stolen data

The content of the leak is said to include a wide variety of sensitive corporate and personal documentation. The information allegedly stolen covers multiple critical business functions, ranging from production processes to administrative records. The group has provided screenshots as evidence, which reportedly include samples of professional certificates and employee resumes.

The data types identified in the leak claim include:

• Manufacturing and quality assurance documentation
• Research and development materials
• Financial records
• Human resources files
• Employee resumes

The exposure of such diverse data types suggests a broad compromise of the internal network environment.

About Luna Group

Luna Group is a major Egyptian conglomerate that has been established since 1966. The organization maintains a significant presence and operates across the Middle East and North Africa region. The company's primary business focus is the manufacturing of various products, including pharmaceuticals, cosmetics, perfumes, and industrial raw materials.

Analysis and potential implications

This breach may lead to the exposure of personal data belonging to Luna Group employees and the compromise of the organization's trade secrets. The publication of financial records and manufacturing process documentation could weaken the organization's competitive advantage and increase supply chain risks. Given that the institution is based in Egypt, legal proceedings under relevant local data protection regulations may be initiated.

Information about the Lamashtu group is limited; however, such leaks often create a foundation for secondary phishing attacks. When sensitive employee information, such as resumes and certificates, is leaked, attackers frequently use these details to craft highly convincing social engineering campaigns targeting both employees and business partners.

In the context of modern cyber threats, ransomware groups often employ double extortion tactics. This involves not only encrypting an organization's systems to disrupt operations but also stealing sensitive data to threaten its public release if a ransom is not paid. This approach increases the pressure on the victim and expands the impact of the attack from operational disruption to long-term reputational and legal damage.

For organizations operating in the manufacturing and pharmaceutical sectors, the loss of research and development materials and quality assurance documentation can be particularly devastating. Such data is often the core of a company's intellectual property. To mitigate the risks associated with such incidents, it is advisable for organizations to conduct a comprehensive forensic investigation to determine the full scope of the leaked data and to strengthen their defensive posture through enhanced monitoring and stricter access controls on internal file servers.
