Detects the creation of files or folders containing suspicious command-line parameters associated with tar or Parallels toolchain injection, specifically looking for the 'use-compress-program' flag which can be abused for command injection.

Detects execution of the tar utility by the prl_disp_service process with a command line pattern indicative of command injection via the --use-compress-program flag. This technique is often used to execute arbitrary commands by embedding them within the compression program argument.

Detects a 'force-push' operation in a Git repository where the pushed commit is not cryptographically signed. This behavior is often indicative of repository tampering, such as overwriting commit history to remove audit trails, hide malicious code injection, or facilitate unauthorized repository modifications.
Detects Git checkout operations involving specific SHA hash arguments that occur in conjunction with potential ambiguous refname errors, or are initiated by processes commonly used for AI-assisted coding (e.g., Copilot, Claude). This rule monitors for potentially malicious source code repository manipulation or automated branch hijacking attempts, often seen in supply chain or development environment attacks.
Detects KATARU IoT malware samples embedding the DirtyFrag (CVE-2026-43284) Linux local privilege escalation exploit copied from public PoC code, as part of a chained LPE attempt targeting root shell spawning
Detects Java-based Metasploit/Meterpreter payload files (.class/.jar) dropped post-exploitation, as observed following PaperCut RCE exploitation chain
Detects the execution of Python interpreters with command-line arguments referencing files commonly used for proxy configurations, such as 'verify3.py', 'proxy_tester', or various '.txt' files located within a '/root/proxy/' directory. This pattern is indicative of potential proxy testing, configuration, or usage of custom proxy-based command-and-control tools.

Detects the GHAPPIER loader pattern: a top-level require('https').get() call to the primevector-app924560.vercel.app C2 that evals the response, disguised inside a large benign-looking JavaScript benchmark file

This rule detects the use of the VS Code command line interface to install extensions, specifically by monitoring for the 'workbench.extensions.installExtension' command. This activity can be indicative of automated installation of extensions, which could be used for malicious purposes or persistence if an attacker installs a malicious extension.
Detects modifications or creation of the VS Code 'settings.json' file within a '.vscode' folder where the configuration includes 'workbench.startupEditor' and 'readme'. This pattern is frequently used in malicious extensions or malicious repository configurations to trick users into opening a malicious README file upon starting the editor, potentially leading to further compromise.
This rule monitors network traffic and internal logs for connections to known malicious IP addresses or domain names associated with 'ClickFix' social engineering campaigns (often impersonating services like HBO Max). The logic explicitly filters out known threat intelligence scanners and security researcher probes. It performs correlation by requiring domain/message matches for generic IP-based alerts to reduce noise, and aggregates events per host over 15-minute windows to produce consolidated alerts.

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.
Detects the creation, modification, or execution of a hidden file named '.rc' located in '/usr/local/bin/'. This behavior is suspicious as it may indicate an attempt to establish persistence or run malicious scripts via hidden configuration files, especially when performed by non-standard installers.
Detects web server processes (e.g., w3wp.exe, nginx.exe, tomcat.exe) spawning command-line interpreters or utilities that could indicate remote code execution, web shell activity, or post-exploitation discovery/download attempts.
