Excellent summary by Solar Designer on oss-security of what's happened in the last two weeks in response to the #xz #backdoor:

https://www.openwall.com/lists/oss-security/2024/04/16/5

Noteworthy:
- #OpenSSH implemented systemd notification
- #systemd moves to dlopen(3) for some dependencies
- another detailed timeline at https://research.swtch.com/xz-timeline
- similar social engineering takeover attempts suspected in #OpenJS and #OpenSSF

We have just issued the first #release of #sshd-openpgp-auth and #ssh-openpgp-auth.

Using this server and client-side tooling it is possible to manage the #authentication of #SSH host keys with the help of an #OpenPGP certificate as trust anchor.
