Protecting fetchremote

[JeViCo]

Hello everyone! How can i protect my fetchremote function from possible bypasses? variable replacement etc?

You might be able to validate the function with:

https://www.tutorialspoint.com/lua/lua_debugging.htm

 

This doesn't stop the function from being overwritten, but you can stop the script operations if the info tells you that a lua function is called instead of a C function.(afaik default mta functions are considered as C functions, but not 100% sure)

print(debug.getinfo(1))

 

 

Maybe getinfo does the job:

Quote

getinfo(optional thread, function or stack level, optional flag)

Returns a table with info about a function. You can give the function directly, or you can give a number as the value of function, which means the function running at level function of the call stack of the given thread − level 0 is the current function (getinfo itself); level 1 is the function that called getinfo; and so on. If function is a number larger than the number of active functions, then getinfo returns nil.
