A tester connects to the finger service on a Unix host. What kind of information is the finger daemon designed to return?
- AA packet capture of all traffic the host has recently sent
- BThe full firewall rule base configured on the host
- CUser details such as login name, home directory, last login and any plan file✓
- DThe root password hash from the shadow file for each account that is held on the local system in this case
Answer: The finger daemon returns account information such as the login name, real name, home directory, shell, last login and the contents of a user's plan file, which aids username enumeration. It does not return password hashes, firewall rules, or packet captures.
