Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
1 distinct threat actor attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
We have also observed code overlaps between SparrowDoor and that group’s HemiGate... These samples correspond to the backdoor that Trend Micro named HemiGate in an August 2023 article.

Payload delivered by Draculoader.
A backdoor with built-in plugin support that appears closely related to or an earlier evolutionary step of modular SparrowDoor. Its plugins support command execution, file operations, keylogging, proxying, shell access, file transfer, screenshots, process control, and file monitoring.
Multi-instance backdoor deployed via DLL sideloading with encrypted payload/config; RC4-decrypts configuration (C2/port) and communicates over HTTPS (port 443), optionally via proxy; provides persistence via registry run key and Windows service; supports keylogging (named pipes), directory monitoring, file read/write and file ops, interactive shell/CMD execution, screenshots, and process enumeration/termination; includes uninstall capability.
A backdoor used by Earth Estries, delivered through DLL side-loading and decrypted by Dracu Loader. The malware shares notable implementation traits with RatelS, especially in HTTP headers, proxy handling, authentication code, keylogging-related paths, and config structure. It was also observed hosted on infrastructure that also hosted PlugX.
