What it detects

This rule detects the Sobolan malware extracting its payloads into hidden staging directories under /var/tmp such as .lol11 and .loll1 that mimic the legitimate ICE temp folders. These dot prefixed paths are unique to the Sobolan cryptomining campaign against exposed JupyterLab servers.
