Apparently ToS is currently using XIGNCODE as its anticheat.
This is a very bad idea. XIGNCODE can autoban people with false positives and cause random crashes. It also isn’t a very effective anticheat. According to google, it uses a simple blacklist and simply renaming any hack executable will allow the hacker to bypass the anticheat. There are also several websites on the first page of results for “XIGNCODE3” that show how one can bypass it, proof of how it’s a horrible anticheat.
