Buffer Overflow P18 | Intro to Binary Exploitation | CTF Walkthrough

In this video walk-through, we covered a scenario of a binary vulnerable to buffer overflow vulnerability. The binary has NX and PIE protections enabled so we opened the binary with Ghidra debugger and built the exploitation methodology based on calculating the offsets of the input variable and another variable that controls an entry to an if statement that prints the flag. The objective was to control the value of that binary and let the execution flow enter the if statement. This was part of HackTheBox Intro to Binary Exploitation Track. *********** Receive Cyber Security Field Notes and Special Training Videos https://www.youtube.com/channel/UCNSdU_1ehXtGclimTVckHmQ/join ********** Writeup https://motasem-notes.net/buffer-overflow-intro-to-binary-exploitation-hackthebox-jeeves/ HackTheBox Jeeves https://app.hackthebox.com/challenges/167 ******** Patreon https://www.patreon.com/motasemhamdan?fan_landing=true Instagram https://www.instagram.com/dev.stuxnet/ Twitter https://twitter.com/ManMotasem Facebook https://www.facebook.com/motasemhamdantty/ LinkedIn [1]: https://www.linkedin.com/in/motasem-hamdan-7673289b/ [2]: https://www.linkedin.com/in/motasem-eldad-ha-bb42481b2/ Website https://www.motasem-notes.net Backup channel https://www.youtube.com/channel/UCF2AfcPUjr7r8cYuMvyRTTQ My Movie channel: https://www.youtube.com/channel/UCilElKPoXEaAfMf0bgH2pzA ******
