Detects the execution of cmd.exe triggered by explorer.exe shortly after a network connection is established to the Peyara Remote Mouse service on TCP port 1313. This pattern is indicative of unauthorized remote command execution via synthetic keystroke injection, bypassing standard interactive session protections.
Detects the execution of wscript.exe or cscript.exe which are commonly used to execute VBScript files for performing host reconnaissance tasks such as process enumeration via WMI and file system discovery using Scripting.FileSystemObject.
Detects unauthenticated network connections to the Peyara Remote Mouse service on TCP port 1313. This service is known to allow remote control of the host, and such unauthenticated Socket.IO connections are often leveraged by attackers to inject synthetic keyboard events, such as triggering the Windows Start menu.
Detects network traffic associated with DcRAT malware, specifically monitoring outbound connections on port 2671 to external non-private IP addresses, or directly to known malicious infrastructure (223.26.63.40). The rule also identifies potential beaconing behavior by analyzing connection intervals and standard deviation, and flags activity originating from specific autonomous system ranges (AS152194) linked to the threat actor's infrastructure.
Detects the spawning of root shells from suid binaries (su) in conjunction with user namespace creation or suspicious parent process execution, potentially indicating exploitation of local privilege escalation vulnerabilities like the pedit COW page cache poisoning (CVE-2026-46331). The detection correlates non-root process activity in suspicious locations with subsequent elevated shell creation.
Detects evidence of the MYRA Linux RAT, which uses LD_PRELOAD hijacking via a malicious library located at /usr/local/lib/.libcache.so for persistence or execution flow hijacking. The rule also identifies the malware's practice of masquerading as the 'systemd-userdbd' service, often launched from a Node.js-based environment.
Detects the execution of PowerShell with suspicious command-line arguments, including obfuscation techniques like base64 encoding, attempts to hide the console window, and strings associated with Pterodo-related tools or backdoors.
Detects outbound network connections to specific cloud storage providers (Wasabi, Tebi, I3Storage) which are commonly leveraged by adversaries for data exfiltration.
Detects network traffic to Cloudflare-hosted services (trycloudflare.com, workers.dev) potentially indicative of C2 communication, especially when initiated by common scripting or proxy processes like powershell.exe, wscript.exe, cscript.exe, mshta.exe, or cloudflared.exe.
Detects the use of common scripting engines (PowerShell, WScript, CScript, MSHTA) to perform system fingerprinting, sandbox detection, or execution timing delays. This activity is often indicative of early-stage malware or reconnaissance tools attempting to identify if they are running in a virtual or analysis environment before proceeding with malicious activity.
