Binary contains a suspicious time stamp
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to query CPU information (cpuid)
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Drops PE files
Enables debug privileges
Extensive use of GetProcAddress (often used to hide API calls)
Found dropped PE file which has not been started or loaded
Found evasive API chain checking for process token information
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
IP address seen in connection with other malware
One or more processes crash
PE file contains executable resources (Code or Archives)
PE file contains sections with non-standard names
PE file does not import any functions
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
