Through-line: the week's scariest headlines (unpatchable silicon flaws, exotic exploit chains) aren't where real damage happens — almost every actual compromise came from the abuse of legitimate, valid access: stolen OAuth tokens, leaked credentials, exposed API keys. The non-obvious insight is that cybersecurity has shifted from a perimeter problem to an identity problem, and AI agents now constitute a new, largely ungoverned population of identities that attackers can hijack without ever touching a login screen. Defense's real question is no longer "who broke in?" but "who was allowed to?"
