Frequently Asked Questions

What account names are likely to be targeted first?

Attackers are described as starting with pregenerated lists of known or probable account names, including root, daemon, ldap, postfix, apache, mysql, sshd, and other predictable names.

What privacy concern is associated with distinguishing valid accounts?

If an attacker scans Internet-facing SSH servers for one that accepts a particular account name, that can associate an IP address with a person or organization. The discussion characterizes account-existence concealment primarily as a privacy feature.
