Insane! You guys are amazing. Reminds me of our old OpeniBoot days... It's a shame we never really finished our yaFTL implementation.
Is it still implemented in software nowadays? Or do they use IOP / eMMC / UFS / some other offloading method?

Both AVR challenges were fun. We spent 5 extra hours on token just because we mixed up 0xaa and 0xdd. Then we reversed the HMAC-SHA1 and figured we might have mixed up key and message. 🤷♂️

It's a good start but it isn't complete. It only gives you a histogram of random bytes from the LFB since it doesn't do the mask-subtract-prefix trick. Also it only reads bytes at offset 0 (mod 64).

@yuvalof and I solved RIDL during #GoogleCTF for @pastenctf. Here's our solution.

... I still don't know exactly why it works though :-)

This is exactly how we solved the challenge. It's crazy that two teams independently solved the challenge with a CPU bug. I wanted to write a write-up earlier but I've been lazy :( Nevertheless this posts pretty much sums it up. Worth reading!

A direct rocket hit on a car in the city of Ashdod. An Israeli man was seriously injured and is in critical condition.

This is from Ashdod, my hometown. Media tends to show a one-sided picture. We had to run to the bomb shelters 6 times in the past 10 minutes. Ashdod is the 6th largest city in Israel. Imagine this situation in Philadelphia, 6th largest city in the USA. twitter.com/EmmanuelNahsho…

Don’t stop believing! We came close but unfortunately didn’t succeed with the landing process. More updates to follow.

Apparently someone has put up an interactive guide to i9300 un-bricking using my tools. I know that I suck at documenting and/or helping users, so this is great news! theandroid02.github.io/i9300-EMMC-GUI…

Make a complete backup of *everything* (including EFS!) - all the data will be lost!
Then follow these steps: (you can boot into download mode so take the easy path)

Please make sure you understand that the risks are of a completely bricked device!
