i downloaded the empress crack of resident evil village and windows defender has detected the file PUA:Win32/SBYinYing. I've looked online for any answers and cant find anything about it. does anyone know what this file is?
While the steps taken to inject the malware into the firmware are somewhat involved, the end result is quite simple: creating a resident software evil that makes sure companion malware is loaded up when a compromised system boots up.
The buffer is a local variable in the printfs function of the sample code, hence it is allocated on the stack. The sample code starts the printer thread with a stack of 1kB. If the buffer is made too big, the stack overflows, and evil things happen. Remember, you're the OS, and you haven't implemented memory protection yet, have you? ;-) Cure: Declare the buffer "static" and it won't be on the stack. But note that the buffer then becomes a global variable (although restricted to the scope of the function in which it is declared). This means that concurrent invocations of the printfs function (from different client threads) will then share the buffer. Hence you'll get more evil results if you allow concurrent calls to printfs.
