zecoxao 1,371 Posted November 28, 2016 Share Posted November 28, 2016 Credits(these go first): Original authors: wskeu(for the reading part), wildcard (for the writing part) Requirements: * 1.76 console * elf-loader * ps4-sdk * the payload source * a brain Steps: 1. Compile the payload. Specifically to what you want to patch, the size, etc. So, this: /* set variables for reading and writing mem */ size_t dumphexsize = 0x200; size_t dumpsize = 0x1; // size that you want to read size_t writesize = 0x1; // size of the data you are overwriting uint64_t base = start[0]; // use the number of the mapping you want to write to, starting with 0 size_t intoBase = 0x465FC9; // relative position of base and this: char *target = "SceShellCore"; 2. Load elf-loader. Let it stabilize on stage 5. (To increase success rate, clear cookies, cache and history) 3. Load the payload. Specifically: #listener socat - TCP:my.ps4.ip:5052 #sender socat -u FILE:path/to/rwmem TCP:my.ps4.ip:5053 4. This payload will take a while to listen to logs. Be patient. After a while it'll show log output with the memory before and memory after. Notes: this is process peek and poke (reading and writing to process memory) using proc_rwmem, which is more efficient than the old method. 6 Link to post Share on other sites
