Interestingly, it looks like ssh-agent disables core dumps[1], but I don't see similar usage for sshd 1: https://github.com/openssh/openssh-portable/blob/69415

  sshd runs as root, so the core dumps would be readable as root-only, no? If you have root access already you could dump it even while it's still running with ptrace anyways

    >sshd runs as root, so the core dumps would be readable as root-only, no Yes, although the article we're discussing shows that you can't rely on that, the dump could be subsequently moved to a developer machine for investigation, and unencrypted key material left in could be compromised that way... defense in depth would make sense here.
