Dekoyap Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

For customers, suppliers, and staff connected to a Turkish building-decoration retailer, the appearance of Dekoyap on a ransomware leak site raises immediate questions about whether personal or business details have left the company’s control. Public reporting on 19 February 2025 states that the group known as thegentlemen claims to have taken internal files during a ransomware attack; the number of people affected remains unknown, and the precise contents of those files have not been confirmed.

That uncertainty itself carries weight. Even a modest retail operation holds contact lists, invoices, and employee records that can be misused for fraud or further intrusion. Until more detail surfaces, anyone who has dealt with Dekoyap must treat the claim as a signal to watch for unusual activity rather than as proof that their own data is already circulating.

Inside the incident

On 19 February 2025, Dekoyap was listed by the ransomware group thegentlemen. The only publicly stated detail is that internal files were exfiltrated as part of a ransomware attack. No figure has been given for the volume of data, the number of systems involved, or the exact date the intrusion began. The method of initial access—whether phishing, an exposed remote-access service, or another vector—has not been disclosed. Likewise, it is unknown whether encryption of systems actually occurred or whether the group relied solely on the threat of publishing stolen material. The listing itself constitutes the group’s claim; independent confirmation of the breach’s scope has not been published.

The group behind it: thegentlemen

thegentlemen is a ransomware operation that became visible in late 2024 and early 2025. Like many contemporary groups, it practices double extortion: data is copied out of the victim’s network before systems are encrypted, and the threat of public release is used to pressure payment. Victims are typically named on a dedicated leak site, often with sample files offered as proof. The group has targeted organisations of varying sizes across multiple countries and sectors, showing no strong preference for any single industry. Public reporting indicates that thegentlemen frequently relies on commodity tools and living-off-the-land techniques once inside a network, though the precise playbook used against any given victim is rarely confirmed. In the case of Dekoyap, the group claims only that internal files were taken; no further statements specific to this company have been made public.

Who is Dekoyap?

Dekoyap is a retail company headquartered in Kocasinan, Kayseri, Turkey. It operates what it describes as Europe’s largest building-decoration store, occupying roughly 15 000 square metres and offering ceramics, parquet flooring, sanitary ware, and bathroom cabinets. Public business directories list the firm as employing between 10 and 19 people and generating annual revenue in the range of 1 million to 5 million dollars. Its website is www.dekoyap.net. As a specialist retailer, Dekoyap necessarily maintains records of suppliers, wholesale and retail customers, inventory, and its own workforce. A compromise of such an organisation can therefore affect both commercial partners and private individuals who have purchased goods or provided personal details in the course of a sale or employment.

What was likely exposed

The sole description available is “internal files exfiltrated in ransomware attack.” No inventory of those files has been released, nor have sample documents been confirmed by independent sources. Organisations of this size and sector typically hold customer contact information, purchase histories, supplier contracts, employee payroll and identity documents, and internal financial records. Whether any of those categories were among the material taken remains unconfirmed. Readers should therefore treat every specific data type as possible rather than established fact until further evidence appears.

Why it matters

Even limited internal files can enable targeted phishing, invoice fraud, or identity misuse. A supplier whose banking details appear in a stolen spreadsheet may later receive a convincing request to change payment instructions. An employee whose national identity number or home address is exposed faces elevated risk of account takeover or social-engineering attacks. For Dekoyap itself, the incident can disrupt operations, damage commercial relationships, and trigger regulatory scrutiny under Turkish data-protection rules. Because the number of people affected is unknown, the practical impact ranges from negligible for some individuals to significant for others; the absence of clear numbers simply prolongs that uncertainty.

What to do if you're exposed

If you have done business with Dekoyap or worked for the company, begin by monitoring bank and credit-card statements for unfamiliar charges and by treating unexpected emails or messages that reference the firm with extra caution. Change passwords on any accounts that may have reused credentials linked to Dekoyap, and enable multi-factor authentication wherever it is offered. Consider placing a fraud alert with credit-reporting services if you supplied identity documents. Finally, you can run a free exposure scan of your email address to check whether it has already appeared in known breach data sets; such a scan will not prove or disprove involvement in this specific incident, but it can reveal whether your address is circulating more widely and prompt further protective steps.
