Machine Learning detection for sample
.NET source code contains potential unpacker
.NET source code contains method to dynamically call methods (often used by packers)
Queues an APC in another process (thread injection)
.NET source code contains very large array initializations
.NET source code contains very large strings
Tries to detect virtualization through RDTSC time measurements
