SPAWNSNAIL is an SSH backdoor that is part of the SPAWN / SPAWNCHIMERA malware ecosystem developed for compromised Ivanti Connect Secure VPN appliances. Reported SPAWNCHIMERA modules include SPAWNANT (installer), SPAWNMOLE (SOCKS5 tunneler), SPAWNSNAIL (SSH backdoor), and SPAWNSLOTH (log wiper / log-tampering component). SPAWNSLOTH is specifically described as tied to the SPAWNSNAIL backdoor and as targeting dslogserver to disable local logging and remote syslog forwarding. The malware ecosystem has been observed post-exploitation following remote code execution against critical Ivanti vulnerabilities including CVE-2025-0282 and CVE-2025-22457, affecting Ivanti Connect Secure appliances including 22.7R2.5 and earlier and Pulse Connect Secure 9.1x. Activity involving SPAWNSNAIL and the broader SPAWN toolkit has been associated by Mandiant / Google Threat Intelligence Group and TeamT5 with suspected China-nexus espionage clusters UNC5337 and the broader UNC5221. The campaigns targeted Ivanti VPN appliances globally across 12 countries and nearly 20 industries, including automotive, chemical, government, financial institutions, and telecommunications. High-confidence indicators in the provided content are limited to its role as an SSH backdoor within the SPAWN ecosystem and its operational linkage to SPAWNSLOTH for log suppression and anti-forensics on Ivanti appliances.
