Hides threads from debuggers
Installs a global keyboard hook
Maps a DLL or memory area into another process
Potential evasive VBS script found (sleep loop)
Queues an APC in another process (thread injection)
Sigma detected: WScript or CScript Dropper
Suspicious execution chain found
Suspicious powershell command line found
Tries to harvest and steal browser information (history, passwords, etc)
Tries to steal Mail credentials (via file registry)
Uses dynamic DNS services
Uses ping.exe to check the status of other devices and networks
Writes to foreign memory regions
Wscript starts Powershell (via cmd or directly)
Abnormal high CPU Usage
Checks if the current process is being debugged
Contains functionality for read data from the clipboard
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to check the parent process ID (often done to detect debuggers and analysis systems)
Contains functionality to dynamically determine API calls
Contains functionality to modify clipboard data
Contains functionality to query CPU information (cpuid)
Contains functionality to read the PEB
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)
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Extensive use of GetProcAddress (often used to hide API calls)
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 large amount of non-executed APIs
Found potential string decryption / allocating functions
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
Java / VBScript file with very long strings (likely obfuscated code)
May sleep (evasive loops) to hinder dynamic analysis
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)

Very long cmdline option found, this is very uncommon (may be encrypted or packed)
Very long command line found
Yara signature match
