xorstring
xorstring
is the implementation of
Malware related compile-time hacks with C++11
by LeFF
but for Rust Nightly (2018 edition).
This XOR encrypts byte-string literals at compile-time with a
XOR-cypher, then decrypts them at runtime. This circumvents simple
.rodata
, .data
, and .text
string checks by anti-cheats such as
Valve Anti-Cheat, in that it can store plain-text internal data
without the anti-cheat noticing it.
Why nightly?
Because of proc_macro_hygiene
.
Where is the under-the-hood implementation?
