So, the threat actor now, after making the compromise, just needs to announce that the previous version has a 0-day, and folks need to install the latest version? I love the idea of a cool down, but it can still be thwarted. I would just hope folks that are trying to patch a 0-day take extra caution to vet the new version. I wouldn't be opposed to a --cooldown 0 doing a side by side diff. I may not know what's going on in the code, but a 0-day shouldn't be a ton of new code either.
