Sample uses string decryption to hide its real strings
Sigma detected: Script Initiated Connection to Non-Local Network
Sigma detected: WScript or CScript Dropper
Suspicious execution chain found
Windows Scripting host queries suspicious COM object (likely to drop second stage)
Wscript starts Powershell (via cmd or directly)
AV process strings found (often used to terminate AV products)

Detected potential crypto function
Downloads executable code via HTTP
Dropped file seen in connection with other malware
Drops PE files
Found WSH timer for Javascript or VBS script (likely evasive script)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Found inlined nop instructions (likely shell or obfuscated code)
HTTP GET or POST without a user agent
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
Java / VBScript file with very long strings (likely obfuscated code)
May sleep (evasive loops) to hinder dynamic analysis
PE file contains sections with non-standard names
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
