This rule detects command-line activity where a remote resource is downloaded via 'curl', decoded using 'base64', and then piped directly into a shell interpreter (sh, bash, or zsh). This pattern is commonly used in fileless execution or stage-one payload delivery by attackers to execute malicious scripts directly from memory.

Detects network communication with domains and IP addresses known to be associated with 'ClickFix' social engineering campaigns (specifically those masquerading as legitimate HBO Max or macOS related updates). The rule applies a strict correlation between observed malicious IP traffic and specific DNS requests to reduce noise from IP address reuse or threat intelligence feed probes, while also excluding known security-related processes.

This rule detects potentially unauthorized access or large-scale extraction of sensitive RADIUS server configuration and credential databases. It monitors for common database management tools and commands used in conjunction with RADIUS-specific paths, particularly when executed by unexpected processes, during off-hours, or in a manner indicative of bulk data export.

This rule detects the use of common command-line utilities (grep, find, bash, sh, awk) to search for sensitive files, such as SSH keys, configuration files containing credentials, or password-related patterns. The rule includes exclusions for common administrative, security, and backup tools that might legitimately perform such scans.
