ICMP-Ghost is a dual-channel C2 tunnelling framework implemented in pure x64 assembly, utilizing ICMPv4 and DNS protocols for covert communication. The author claims advanced evasion capabilities against EDR and Suricata IDS/IPS. Despite these claims, the article provides detailed protocol structures and detection rules using PacketSmith Yara-X modules to detect the ICMP and DNS tunnelling traffic generated by ICMP-Ghost. This detection approach enables defenders to identify and mitigate the presence of this implant in their networks.

The framework enables covert command and control communication using ICMP and DNS tunnelling, potentially allowing attackers to maintain stealthy control over compromised systems. Its evasion claims, if accurate, could hinder detection by common endpoint and network security tools, increasing the risk of prolonged undetected intrusion.

Detection rules using PacketSmith Yara-X and ICMP detection modules are available to identify ICMP-Ghost C2 traffic. Organizations should deploy these detection capabilities to monitor for and respond to such covert channels. No official patches or vendor advisories exist since this is an open-source framework rather than a software vulnerability. Standard network monitoring focused on ICMP and DNS tunnelling traffic patterns is recommended.
