SECiL Listed by Deadlock Ransomware Group

On May 22, 2026, Turkish rubber manufacturer Seçil Kauçuk was listed on the leak site of the Deadlock ransomware group after internal files were exfiltrated during a ransomware attack. The company, which produces gaskets, sealing profiles, and molded parts for construction, automotive, and infrastructure projects, had customer, supplier, and employee information among the stolen data now publicly available for anyone to download.

What's Publicly Reported from Reporting

Public reporting indicates that Seçil Kauçuk was added to Deadlock’s leak portal on May 22, 2026. The data consists of internal files exfiltrated after the ransomware deployment. No confirmed victim count has been released, and the precise volume of records remains undisclosed. The company, founded in 1983 and based in a 70,000-square-meter facility in Tarsus, Turkey, exports to more than 50 countries and operates an official R&D center.

Available reporting describes the exposed material as sensitive business documents that could include contracts, employee details, and partner information. Ransomware.live has mirrored the listing, making the data accessible beyond the original extortion portal.

Why This Matters for You and Your Family

When a manufacturer like Seçil Kauçuk is breached, the information that leaks often contains names, addresses, phone numbers, email accounts, and sometimes national ID or tax numbers of ordinary people — customers, suppliers, and employees. If your data or your family’s data was in those files, it can be combined with other leaks to build a complete profile.

Credential leaks like this one frequently cascade into account takeovers. A password or email address taken from a supplier portal can be tested against your banking, email, or social media accounts. Children’s gaming accounts tied to family email addresses are especially vulnerable because gaming platforms often use weak or reused credentials.

The Doxxing and Identity-Chain Implications

Once internal files appear on a ransomware leak site, opportunistic actors begin mapping the data. They link employee names to personal email addresses, then to social-media handles, then to family members. This identity-chain process turns a single breach into long-term exposure that can lead to targeted phishing, SIM-swapping, or physical harassment.

Children’s gaming accounts are frequently the weakest link. A gamer tag connected to a parent’s leaked work email can expose the entire household address and phone number. Public reporting shows these chains grow quickly once the initial dataset is published.

Deadlock Ransomware Group Track Record

Public reporting attributes Deadlock with emerging in late 2024. The group has targeted mid-sized manufacturing and logistics companies across Europe and the Middle East. Notable prior victims include other industrial suppliers whose customer databases were published after ransom demands went unpaid.

Their typical playbook involves initial access through phishing or exploited remote desktop services, followed by data exfiltration before encryption. They then demand payment and, if unmet, publish samples and eventually the full archive on their leak site with countdown timers. Extortion style focuses on reputational damage to pressure victims into paying rather than solely relying on file encryption.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by specialists.
• Rotate any password you used at Seçil Kauçuk or its supplier portals anywhere it is reused, and enable 2FA through an authenticator app instead of SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your information is caught in hours, not months.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that chain back to the same address or email.
• Let the remediation specialists perform hands-on takedown requests across data brokers and leak sites on your behalf.
