WebA register is a location within the processor that is able to store data, much like RAM. Unlike RAM however, accesses to registers are effectively instantaneous, whereas reads from main memory can take hundreds of CPU cycles to return. Registers can hold any value: addresses (pointers), results from mathematical operations, characters, etc. WebAnd Heap Exploitation because atleast in my opinion, heap allocator exploits are where you start to see some of the real creativity that is part of exploitation. Though if you want to get deep into it, Shellphish how2heap is a more complete resource, and Max Kamper's Linux Heap Exploitation (paid) is a really good, but not free course.
WebAug 6, 2024 · Data Execution Prevention (DEP), referred to as No-eXecute (NX), was one of the first mitigations that forced researchers and adversaries to adopt additional methods of exploitation. DEP prevents … WebThe most basic forms of binary exploitation occur on the stack, a region of memory that stores temporary variables created by functions in code. When a new function is called, a memory address in the calling function is pushed to the stack - this way, the program knows where to return to once the called function finishes execution.

WebJun 8, 2024 · Solution. The binary is made to confuse decompilers. If you look at the disassembly, you can see that there’s a stack variable that is checked when the loop exits. If it’s zero, the flag will be printed. We can abuse the format string vuln to leak the stack address of the variable and zero it out on the second go.

As we saw in buffer overflows, having stack control can be very powerful since it allows us to overwrite saved instruction pointers, giving us control over what the program does next. biological literacy includes the ability to:
