Circuit Breaker

Reflective loading of embedded executable. Embedded executable uses opaque predicates, virtualizations and antialias techniques to obfuscate the decoding of a stored string based on 2nd-order Runge-Kutta and time. Rewrite binary to use input/hex instead of time to decode string.

Description (public)

I have signed up for a shady beta test regarding a Singaporean made Meme Generator. All they gave was this binary, which generates the same meme every time?! Whenever I exit, the binary goes funky too. (Though it does print something different ever so often, perhaps I can control that?)
