Some common password hashing schemes only process the first eight characters of a user's password, which reduces the effective strength of the password.

Verify no password hash in /etc/passwd or /etc/shadow begins with a character other than an underscore (_) or dollar sign ($).

# cut -d ':' -f2 /etc/passwd
# cut -d ':' -f2 /etc/shadow

If any password hash is present that does not have an initial underscore (_) or dollar sign ($) character, this is a finding.
