Moving from saved RIP control to a small ROP chain that loads 0xdeadbeef into RDI before calling win.- Published on
A 64-byte buffer, an oversized read, and 72 bytes to saved RIP: how my first ret2win payload redirected control flow.- Published on
My first pwn lab was a debugger drill: follow a function call, find its arguments and locals, and understand saved RBP and RIP.- Published on
The roadmap for my hands-on Linux x86_64 binary exploitation series, from stack fundamentals to advanced pwn.
