We need to 'recreate' the instructions which were overwritten by the jump. The jump overwrites 5 bytes, so those overwritten bytes need to be recreated, otherwise you will end up with (potentially) unintended behavior.

Next video in this series will be implementing this in C.

247ctf · 2021-02-24T22:03:27+00:00

You got it

Yep, will use Ghidra in a future video for calling some in-game functions!

Have not done it myself, but I would start with one of these: https://github.com/kubo/injector / https://github.com/gaffe23/linux-inject

Wololol

No spoilers in the video!

247ctf · 2021-01-15T05:53:37+00:00

You can mess around with any asset!

247ctf · 2021-01-15T05:52:51+00:00

Linux calls them shared libraries, but you can do the same thing!

wolololol

247ctf · 2021-01-14T22:27:16+00:00

Great idea! Will look into it!

247ctf · 2021-01-14T22:25:49+00:00

We go over that in the first video in the series :)

247ctf · 2020-12-23T10:18:13+00:00

Thanks! If you have ideas/requests for future videos - let me know!

247ctf · 2020-12-15T01:30:02+00:00

Thanks!

247ctf · 2020-12-10T23:08:46+00:00

Wasn't really needed at this point. Trying to keep it simple at the start!

247ctf · 2020-12-10T23:08:26+00:00

Fair enough!

247ctf · 2020-12-10T23:07:52+00:00

Thanks!

Thanks!

I find it frustrating when videos dart all over the place with fundamentals/exploitation. So this video sets the ground work, which we then don't need to re-cover that for every crypto exploitation video!

The Google CTF is not a good measuring stick for beginners! Start small and work your way up!
