SECiL
About the organisation
Seçil Kauçuk is a Turkish manufacturer, founded in 1983, specializing in rubber gaskets, sealing profiles, and industrial molded parts for sectors including construction, automotive, and infrastructure.

What the listing means
SECiL appeared on the Deadlock leak site on 15 June 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated — the attack itself is dated 22 May 2026, 23 days before the listing. This group has published 75 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing SECiL as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on www.seciltr.com, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Watch for follow-on extortion: stolen data is often re-leaked or resold after the initial listing.
- A leak-site listing is a claim made by the attacker, not a confirmed breach — check the organisation's own disclosures before acting on it.
