This was an awful write up. I want to know how, over multiple days worth of mitigations, the attacker remained in the system. I want to know exactly, from a detailed technical perspective, what flaws there were, what actions have been taken to fix them, and how you can be positive an attacker won’t gain access in the same manner. This post is so high level that it sounds like railway doesn’t even know the answer to them.
