Found large amount of non-executed APIs
Found potential string decryption / allocating functions
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
OS version to string mapping found (often used in BOTs)
PE file contains an invalid checksum
Potential key logger detected (key state polling based)
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
