Whoa, package managers as attack vectors? That's a nasty one. 😬 It really highlights how much trust we put in these core system tools. Makes you think about the integrity checks on *every* dependency pull. Hopefully, the community patches this super fast; waiting for those patch windows is always the riskiest part of keeping things secure. Gotta keep an eye on those repo signing keys! 🛠️💻
