This. If u want to excel as a security person in our industry u need to properly understand what a reentrancy attack is, what mistakes have happened & how to prevent them. I've built this repo to be a public good. So use it to learn from past mistakes! github.com/pcaversaccio/r

Today I started to read the articles of @pcaversaccio about Reentrancy Attacks which already happen, so far I understand that the same mistakes are often repeated, the most common one, surprisingly or not is the lack of Check-Effect-Interaction principle.

Here’s how signature malleability attacks work.
Two attacks.
If a user signs the same message multiple times, they get a different signature each time. If your code uses a signature as an identifier for blocking actions, users can repeat that action. 1/3
