Monitors registry run keys for changes
Powershell drops PE file
Sigma detected: Dot net compiler compiles file from suspicious location
Tries to harvest and steal browser information (history, passwords, etc)
Tries to harvest and steal ftp login credentials
Tries to steal Crypto Currency Wallets
Compiles C# or VB.Net code
Contains functionality for read data from the clipboard
Contains functionality to dynamically determine API calls
Contains functionality to retrieve information about pressed keystrokes

Creates files inside the system directory
Detected non-DNS traffic on DNS port
Detected potential crypto function
Dropped file seen in connection with other malware
Drops PE files
Enables debug privileges
