Bypasses PowerShell execution policy
Obfuscated command line found
Sigma detected: Suspicious PowerShell Parameter Substring
Suspicious powershell command line found
Uses dynamic DNS services
AV process strings found (often used to terminate AV products)
Abnormal high CPU Usage
Checks if Antivirus/Antispyware/Firewall program is installed (via WMI)
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Detected TCP or UDP traffic on non-standard ports
Enables debug privileges
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
