Initial sample is a PE file and has a suspicious name
Machine Learning detection for dropped file
Machine Learning detection for sample
Sigma detected: WScript or CScript Dropper
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Windows Scripting host queries suspicious COM object (likely to drop second stage)
Yara detected Costura Assembly Loader
Yara detected Generic Downloader
Allocates memory with a write watch (potentially for evading sandboxes)
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Creates a start menu entry (Start Menu\Programs\Startup)
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Drops PE files
Enables debug privileges
Found WSH timer for Javascript or VBS script (likely evasive script)

HTTP GET or POST without a user agent
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
JA3 SSL client fingerprint seen in connection with other malware
May check the online IP address of the machine
May sleep (evasive loops) to hinder dynamic analysis

Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
Sample file is different than original file name gathered from version info
Sigma detected: WSF/JSE/JS/VBA/VBE File Execution Via Cscript/Wscript
Stores files to the Windows start menu directory
Uses 32bit PE files
Uses a known web browser user agent for HTTP communication
