This rule detects scenarios where a device registration event occurs within 15 minutes of a device-code authentication sign-in for the same user. This pattern is indicative of potential account manipulation where an adversary registers their own device to an existing account to maintain persistent access or bypass multi-factor authentication (MFA).

Detects Java-based Metasploit/Meterpreter payload files (.class/.jar) dropped post-exploitation, as observed following PaperCut RCE exploitation chain
This rule detects suspicious usage of certutil.exe for file downloading or the execution of the Chisel proxy tool, specifically targeting connections or authentication towards the suspicious IP address 69.48.228.86. This behavior is indicative of C2 communication or ingress tool transfer.
This rule detects SQL injection attempts targeting the BuddyBoss members REST endpoint, specifically identifying exploitation patterns associated with the 'sqlmap' tool. The rule monitors for specific URL parameters including 'member_type', 'search_terms', and 'scope' in combination with an 'sqlmap' user-agent, indicating an automated exploitation attempt against the application.
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 outbound network traffic consistent with the Chisel proxy/tunneling tool establishing a connection to an external VPS associated with the Miku threat actor. The rule monitors for established TCP connections to a specific remote IP address on port 443, utilizing a threshold to reduce noise by ensuring multiple connection attempts occur.
This rule detects suspicious activity involving the creation of scheduled tasks for persistence using command-line arguments indicative of tool execution (e.g., chisel, powershell) or the direct execution of hidden PowerShell scripts intended to bypass execution policy.
