A node/python/pip-driven package install resolves a domain that Palo Alto classifies as newly-registered within seconds of the install. This signals a potential malicious dependency or compromised package beaconing to attacker infrastructure (supply-chain compromise / install-time C2).

Detects the 'node' process creating hidden JavaScript or native loader files (e.g., .js, .node, .so, .dylib, .bin) in user profile or temporary directories. This activity is indicative of the OpenClaw malware's staging phase, where it drops its components for persistence or further execution.

Detects the installation of specific Chrome browser extensions associated with the 'BadBlocker' campaign. These extensions are known to request broad host permissions, allowing them to access data across all websites, which can lead to sensitive information theft, credential harvesting, or session hijacking.

This rule monitors and alerts on network connections originating from hosts to known command-and-control (C2) or infrastructure domains associated with malicious browser extensions, specifically those identified in the BadBlocker campaign. These extensions often masquerade as legitimate ad-blocking tools to perform lifecycle beaconing or redirect users to promotional/malicious content.

Detects attempts to access SSH private keys (id_rsa, id_ed25519) or public keys (.pub files) by 'node' or 'python' processes. This activity could indicate an attacker attempting to collect SSH credentials for lateral movement or persistence.

Detects anomalous, high-frequency bidirectional WebSocket connections (wss/ws) originating from an endpoint that match patterns associated with Bluekit BitM. These connections typically carry DOM serialization events (rrweb-style) and session handshake data, indicative of a victim's keystrokes and mouse movements being relayed to an attacker-controlled browser session.

Detects the use of the 'chmod' command to modify file permissions on critical system directories or files such as /etc/passwd, /etc/shadow, and various log directories. This activity is often indicative of an adversary attempting to facilitate privilege escalation, maintain persistence, or hide malicious artifacts.

This rule detects suspicious update requests to the Ghost CMS Admin API that indicate an attempt at dynamic script injection. It specifically looks for PUT requests to `/ghost/api/admin/posts/` containing markers associated with Base64 decoding (`atob(`) and dynamic DOM manipulation (`appendChild`, `createElement`), or specific strings (`ghost_once_footer_`, `btoa(a.origin)`) known to be used in the Ghost ClickFix attack chain. This activity suggests an attacker is attempting to inject malicious JavaScript into Ghost CMS content, potentially leveraging a vulnerability like CVE-2026-26980.

This rule detects activity associated with malicious or intrusive browser extensions, specifically identifying network connections to a known malicious command-and-control (C2) endpoint, execution of specific scriptlet keywords related to MAIN-world injection in browser processes, and the presence of known 'BadBlocker' extension IDs on endpoints.

This rule detects potentially malicious activity associated with the exploitation of Ray framework dashboards. It identifies three distinct indicators: inbound network connections to the Ray dashboard port (8265), the execution of common file download tools (e.g., curl, wget) by Ray worker processes, and outbound connections from Ray processes to known C2 infrastructure.

Detects various methods of establishing persistence on Linux systems by abusing dynamic linker configuration (/etc/ld.so.preload), modifying shell startup profiles (.bashrc, .profile) to include malicious environment variables (LD_PRELOAD/LD_LIBRARY_PATH), or directly launching processes with these hijacked variables pointing to suspicious locations such as /tmp, /dev/shm, or /var/tmp.

This rule detects potentially malicious cron job activity, including modifications to crontab files, execution of cron jobs from world-writable directories (such as /tmp or /dev/shm), and the usage of unusual prime-number timing intervals which are commonly used by attackers to evade standard scheduling patterns.

Detects instances where a GitHub Actions runner requests an OIDC token and subsequently executes an npm publish command within 5 minutes. This behavior is indicative of unauthorized package deployment, potentially exploiting GitHub's OIDC 'trusted publishing' mechanism, as observed in the Miasma worm campaign.

Detects vLLM establishing outbound network connections to fetch external media files (e.g., .mov, .mp4, .jp2) from non-private IP addresses. This activity may indicate exploitation of CVE-2026-22778, allowing for remote code execution by fetching malicious content.

Detects the initial stage of the Meow RAT ClickFix campaign, specifically targeting fileless zsh loaders. This rule identifies command-line executions involving 'zsh', 'bash', or 'sh' that combine 'eval', 'base64', 'gzip', and either 'curl' or 'osascript', often with redirection to /dev/null. This pattern is indicative of a gzip+base64 encoded heredoc being fetched via curl and executed in memory, followed by osascript for further actions.
