Openclaw Curl Install Script
This rule set detects attempts to download an 'install.sh' script from the domains 'clawd.bot' or 'openclaw.ai' using various methods. The first rule, 'openclaw_curl_install_script', specifically targets command-line tools like curl, wget, aria2c, and fetch. The 'openclaw_powershell_download' rule focuses on PowerShell commands (Invoke-WebRequest, iwr, Invoke-RestMethod, irm) used for downloading. The 'openclaw_aria2c_fetch_download' rule is redundant with the first rule, as it also targets aria2c and fetch. The 'openclaw_lolbin_download' rule identifies the use of Living Off The Land Binaries (LOLBins) such as certutil, bitsadmin, and mshta for the same download activity. Finally, the 'openclaw_http_install_sh' rule detects direct HTTP network requests to the 'install.sh' path on these domains. Collectively, these rules aim to identify potential initial access or execution attempts involving a suspicious installation script from specific domains.
