Berko İlaç Ve Ki̇mya San Aş Listed by qilin Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target manufacturing and healthcare-adjacent firms, using data theft and public leak-site postings to pressure victims. In this environment, listings of mid-sized industrial companies have become a recurring feature of the threat landscape, often leaving the true scale of any compromise unclear for weeks or months.

On 22 May 2025 the ransomware group qilin listed Berko İlaç Ve Kimya San Aş on its leak site, claiming to have exfiltrated internal files in a ransomware attack. The number of people affected remains unknown, and public detail about the incident is limited. The listing itself is an unverified claim by the group; independent confirmation of the breach’s full scope has not been published.

Breaking down the breach

According to the available record, Berko İlaç Ve Kimya San Aş was named by the qilin ransomware group on 22 May 2025. The group asserts that internal files were taken during a ransomware attack. No further technical details—such as the initial access vector, the duration of the intrusion, the volume of data removed, or any ransom demand—have been disclosed in the public summary. The number of individuals whose information may have been involved is listed as unknown. Because the only concrete statement is the group’s own leak-site claim, the precise timeline and method of the incident remain unconfirmed.

Who is qilin?

Qilin is a ransomware operation that has been active for several years and is known for a double-extortion model: encrypting systems while simultaneously stealing data and threatening to publish it. The group typically operates as a ransomware-as-a-service, recruiting affiliates who conduct the intrusions and then share proceeds. Public reporting has linked qilin to attacks on organisations across manufacturing, professional services and other sectors, often accompanied by leak-site postings that list victim names and sample files. In this case the group claims Berko İlaç Ve Kimya San Aş as a victim and states that internal files were exfiltrated; those assertions have not been independently verified beyond the listing itself.

Berko İlaç Ve Kimya San Aş and its sector

Berko İlaç Ve Kimya San Aş is a Turkish pharmaceutical and chemical manufacturing company. Public background material describes its origins in the work of pharmacist Berat Beran, who moved from retail pharmacy into production. Firms of this type develop, manufacture and distribute medicines and chemical products, maintaining relationships with suppliers, distributors, healthcare providers and regulators. They routinely hold commercial contracts, research and development records, quality-control documentation, employee information and, in many cases, data linked to product distribution. A ransomware incident affecting such an organisation can disrupt production, supply chains and regulatory compliance, and can place sensitive commercial or personal data at risk of further misuse.

What was likely exposed

The only data category named in the public record is “internal files exfiltrated in ransomware attack.” No inventory of specific file types, databases or record counts has been released. Organisations in the pharmaceutical and chemical sector typically store employee personnel files, customer and supplier contact details, manufacturing formulas, quality-assurance records, financial documents and correspondence with regulators. Whether any of those categories were among the files taken in this incident is unconfirmed. Until the company or independent investigators publish a fuller accounting, the exact contents of the claimed exfiltration remain unknown.

What's at stake

For individuals whose data may have been among the internal files, the practical risks include targeted phishing, identity fraud or unsolicited contact that leverages personal or professional details. Employees could face exposure of payroll, identity or health-related information; business partners could see commercial terms or contact data reused by criminals. For the organisation itself, the stakes include operational disruption, potential regulatory scrutiny under data-protection rules, loss of proprietary manufacturing knowledge, and reputational damage that can affect customer and partner confidence. Because the number of affected people is unknown and the precise data types are undisclosed, the full extent of these risks cannot yet be quantified.

What to do if you're exposed

Anyone who has worked with, supplied or received services from Berko İlaç Ve Kimya San Aş should treat the possibility of exposure seriously even while details remain limited. Monitor bank and credit accounts for unusual activity, enable multi-factor authentication on email and work-related accounts, and be alert to phishing messages that reference the company or pharmaceutical topics. Change passwords that may have been reused across personal and professional systems. If you receive unexpected requests for personal or financial information, verify them through independent channels. Readers can also run a free exposure scan of their email address to check whether their information has already appeared in known breach data sets; such a check provides an early indication of wider circulation and can guide further protective steps.
