The ROBOT CTF - Return of Bleichenbacher's Oracle Threat
In my case, as my objective was understanding everything behind ROBOT, I prepared the code to perform the attack all by myself. The only library I used was gmplib, in order to perform big …
ROBOT Attack
It's hardcoded with a particular blinded value because I parallelised the code in two parts (blinding then the other queries) as I was executing the attack and saving the blinded value allowed me …
