In this picoGym (picoCTF) Workout video, we do a writeup of the Reverse engineering a UPX packed executable with Ghidra after unpacking. Using ROPgadget to build a return-oriented-programming chain of addresses that give a shell. Pollard's p-1 attack on RSA unsafe primes. Uses code from: modified as ... changing a function pointer in C; bounds check only checks for too large, not negative numbers.
simple buffer overflow with returning to two different functions and reusing stack memory. Using LOTS of compression software to get flag from file compressed many times with many algorithms. reverse engineering with Ghidra and modifying an executable using a hex editor. LSB (least significant bit) steganography using st3go Uses pollard p-1 to factor product of smooth primes, and Pohlig-Hellman from sagemath to solve discrete logarithm problem. Using grep to find flag in large text file.
