And yet...

1. practically all hyperscalers use it

2. desktops

3. container images, that power everything from docker to kubernetes use it

It helps that it's actively maintained, battle-tested as hell, and widely audited.

Point being, it's fun to hate on systemd, and maybe even hipster-like, and systemd is hardly perfect... but you are probably more likely to be exploited by a pypi or npm supply-chain attack.

Is it actually audited? Or is it like OpenSSL... everybody uses it, but nobody looks under the hood cause it's gross in there? (Or well, nobody looked before Heartbleed anyway)

This is 2026, not 2014 when heartbleed came out.

And it runs as PID1 on many distros and these are folks like RHEL, who have a huge interest in keeping it secure.

Pypi has an almost daily exploit announced in common and popular libraries, simply because the dependency graph is so huge. And this is in things that are almost certainly deliberately and by design exposed to insecure user input.

Again, it’s fun to hate on systemd, but in reality you are much more likely to be exploited by something else.

Can you even imagine pypi or npm compromising ssh this way?

Is ssh somehow sacrosanct in a way that any other RCE or credential stealing attack is different?

I don’t even know the last time I exposed ssh to the open internet.

But the fact with npm or pypi you can be exploited just by running the software you’ve already installed because the dependencies are everywhere on your system?

I see ssh as a very fundamental part of the system - in BSD terms it's in base not ports. Random packages from npm or pypi, sure, if you installed some slop off the internet and got exploited that's not so surprising. (Even those package managers themselves are not part of the base system, much less anything you install with them). But ssh should be safe!
