Creates files inside the system directory
Internet Provider seen in connection with other malware
Detected potential crypto function
Found potential string decryption / allocating functions
Found evasive API chain (may stop execution after checking a module file name)
Contains functionality to check if a debugger is running (OutputDebugString,GetLastError)
Contains functionality to dynamically determine API calls
IP address seen in connection with other malware
PE file contains an invalid checksum
Tries to load missing DLLs
Drops PE files to the windows directory (C:\Windows)
