Sample file is different than original file name gathered from version info
PE file contains strange resources
Drops PE files
Tries to load missing DLLs
Contains functionality to read the PEB
Uses a known web browser user agent for HTTP communication
Detected TCP or UDP traffic on non-standard ports
Checks if the current process is being debugged
Uses SMTP (mail sending)
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Creates a process in suspended mode (likely to inject code)
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to detect virtual machines (SGDT)
Contains functionality for read data from the clipboard
