Found API chain indicative of sandbox detection
Machine Learning detection for sample
Connects to many different domains
Contains functionality for execution timing, often used to detect debuggers
Contains functionality for read data from the clipboard
Contains functionality to block mouse and keyboard input (often used to hinder debugging)
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to check if a window is minimized (may be used to check if an application is visible)
Contains functionality to communicate with device drivers
Contains functionality to dynamically determine API calls
Contains functionality to execute programs as a different user
Contains functionality to launch a process as a different user

Detected potential crypto function
Drops PE files
Enables debug privileges
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
IP address seen in connection with other malware
JA3 SSL client fingerprint seen in connection with other malware
OS version to string mapping found (often used in BOTs)
