T1218.011Rundll32Evidence1

Command and Control

4 techniques
T1071Application Layer ProtocolEvidence1

Velociraptor, for command-and-control (C2). Visual Studio Code and Cloudflare Tunnel, for tunneling C2 communications. Yuze, for intranet penetration and establishing a reverse proxy connection to the attacker's C2 server across HTTP (port 80), HTTPS (port 443), and DNS (port 53).

T1090ProxyEvidence2

Yuze, for intranet penetration and establishing a reverse proxy connection to the attacker's C2 server across HTTP (port 80), HTTPS (port 443), and DNS (port 53).

T1090.002External ProxyEvidence1

Cloudflare Tunnel... the attacker first registered it as a persistent Windows service... The tunnel run --token command then authenticated the compromised machine to the attacker's Cloudflare account... The TA leveraged VS Code's built-in tunneling capability to establish a covert C&C channel... Yuze... supports forward and reverse SOCKS5 proxy tunneling.

T1105Ingress Tool TransferEvidence1

These methods include exploiting the Nsec driver with a new BYOVD technique as well as using the remote-access tool TightVNC and the reverse-proxy tool Yuze...
