Sandbox Detection Tricks & Nice Obfuscation in a Single VBScript , (Fri, Feb 7th)

I found an interesting VBScript sample that is a perfect textbook case for training or learning purposes. It implements a nice obfuscation technique as well as many classic sandbox detection mechanisms. The script is a dropper: it extracts from its code a DLL that will be loaded if the script is running outside of a sandbox. Its current VT score is 25/57 (SHA256: 29d3955048f21411a869d87fb8dc2b22ff6b6609dd2d95b7ae8d269da7c8cc3d)[1].
