Switches to a custom stack to bypass stack traces
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)
Windows Scripting host queries suspicious COM object (likely to drop second stage)
Writes to foreign memory regions

Creates files inside the system directory
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
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)
IP address seen in connection with other malware
Installs a raw input device (often for capturing keystrokes)
JA3 SSL client fingerprint seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Queries disk information (often used to detect virtual machines)
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 execution stops while process was sleeping (likely an evasion)
