DragonsGate Loader: The Evolving Download Mechanism Behind TamperedChef / EvilAI

DragonsGate Loader analysis: TamperedChef/EvilAI installers, anti-analysis techniques, server-side gating, YARA rules and IOCs. Research update | November 11, 2026 During ongoing investigation into the TamperedChef / EvilAI ecosystem, we have continued to encounter suspicious application installers distributed through gated advertising campaigns .

CookUp: Suspicious Server-Gated Installer and Loader Analysis Malware Research / Technical Analysis Inside CookUp: A Suspicious Server-Gated Installer and In-Memory Loader CookUp is a recipe application distributed by an installer that also contains a suspicious, server-controlled remote-loading workflow. The installer drops/installs cookup.exe, a .NET recipe application with a limited JSON-based recipe database; in the observed installation, that application appeared functional and benign. The separate Go-based installer can activate a downloader and contains code for processing and loading native PE modules. No authentic second-stage payload was recovered, and malicious activity has not been established.
