One report this week basically reads like a guy tripped over root access by accident and decided to stay

Defending a network at 2 am looks a lot like this: an analyst copy-pasting a hash from a PDF into a SIEM query. A red team script is being rewritten by hand so the blue team can use it. A patch waiting on a change-approval window that's longer than the exploitation window itself. Nobody in that chain is incompetent. Every human is doing their job correctly. The problem is the system, its
