Sigma detected: MSBuild connects to smtp port
Snort IDS alert for network traffic
Tries to steal Mail credentials (via file / registry access)
Tries to harvest and steal Putty / WinSCP information (sessions, passwords, etc)
Tries to harvest and steal ftp login credentials
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Machine Learning detection for sample
.NET source code contains potential unpacker

Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Yara signature match
Antivirus or Machine Learning detection for unpacked file
May sleep (evasive loops) to hinder dynamic analysis
Detected potential crypto function
Yara detected Credential Stealer
IP address seen in connection with other malware
Contains long sleeps (>= 3 min)
Enables debug privileges
