HYFLOCK lists alleged Merkez İlaç data on leak site
The threat actor known as HYFLOCK has listed data allegedly belonging to the Turkey-based pharmaceutical and hygiene product manufacturer Merkez İlaç on its leak site. This announcement, made on October 13, 2026, marks a potential significant breach for the long-standing manufacturer. While the group has posted claims regarding the theft, the information remains an allegation from the threat actor.
Details of the alleged attack and group activity
On October 13, 2026, the HYFLOCK group listed data belonging to Merkez İlaç on its leak platform. To support their claim, the threat actor shared sample documents that are claimed to be related to the company's operational processes and internal documentation. Following this listing, the group has initiated a countdown process for the publication of the alleged data.
Publicly available information regarding the HYFLOCK group is currently limited. In the landscape of modern cybercrime, ransomware groups often utilize leak sites to exert pressure on victims through a tactic known as double extortion. In such scenarios, attackers do not merely encrypt a company's systems but also threaten to release sensitive stolen data to the public to increase the likelihood of a ransom payment. While the specific ransom demand and the total size of the data stolen have not been disclosed by the group, the initiation of a countdown suggests an imminent threat of data publication.
Scope of the alleged data exposure
The screenshots provided by the threat actor contain internal documents regarding the company's standard operating procedures, job descriptions, and quality management processes. Based on the information shared by the group, the following types of data are claimed to be affected:
- Corporate operational documents
- Internal procedure documents
- Job and responsibility descriptions
The exposure of such documentation, even in sample form, provides insight into the internal workings of the organization. It is important to note that the group has not provided specific details regarding the exact file count or the total volume of data involved in this incident.
About Merkez İlaç
Founded in 1934, Merkez İlaç is one of Turkey's long-standing pharmaceutical and hygiene product manufacturers. The company produces disinfectants, OTC medicines, ointments, and first aid kits, while also providing contract manufacturing services for other pharmaceutical companies. Given its role in the healthcare supply chain, the organization maintains a significant presence in the production of essential medical and hygiene supplies.
Potential impact and industry risks
The leak claim brings the risk of exposing sensitive operational information regarding the company's internal processes. The publication of such documents may have negative impacts on the company's production standards and quality management processes. Furthermore, the leakage of such data may trigger legal processes regarding data security obligations under KVKK.
Secondary risks include the possibility that the obtained information could be used in supply chain attacks or targeted phishing campaigns against the organization. Given the company's extensive supply network in the healthcare sector, a potential data breach could lead to widespread operational disruptions. In the pharmaceutical industry, maintaining the integrity of quality management and standard operating procedures is critical to ensuring product safety and regulatory compliance.
To mitigate such risks, organizations in this sector typically focus on robust data security frameworks, including strict access controls, continuous monitoring of internal networks, and comprehensive employee training to prevent phishing. Protecting the integrity of operational documentation is essential to prevent attackers from gaining the knowledge required to execute more sophisticated, targeted attacks against the organization's infrastructure or its partners in the supply chain.
