![]() Ok, now use (ALT+M) to see memory map and scroll down where you see something like this.Ĭopy the first address 0x00320000, maybe you will see another address (ASLR), but concept is same. ![]() This address where passfab start is used for reconfigure all the address in IDA Tools. We need to found hex address ex: 0x01234567 where the passfab.exe is start, because this software have ASLR (Address Stack Layer Randomize, for more info check Wikipedia) protection on, that means the address is all time changed. Run 圆4 with Administrator Privilege because PassFab run just with this privilege.Īttach the program is done. I use: IDA PRO 6.8 Version for static analyze and 圆4dbg for dynamic analyze.įirst step is loading a software in 圆4dbg is easy to use (ALT+A to attach the application). Let’s dirty my hands: For replicate every step we need few tools for disassembly the software. Exploitation this application is not dangerouse for users, but using this buffer I was able to steal all the (Serial Keys). When more data than initially allocated for storage is exceeded causes a change in memory, these additional data slip into other storage areas, which may corrupt or overwrite the data it holds. First time I will explain what Buffer Overflow vulnerability is.īuffer Overflow: The buffer is a temporary area for storing data. Here is a Proof of Concept, about how I was able to Crack PassFab Software with Buffer Overflow Vulnerability.
