I'm sorry to hear that. In the Asterisk source there is a doc that 
focuses on security. you might want to read that. Google should give you 
more information about Asterisk/SIP security. Also you may want to 
install something like fail2ban which prevents brute forcing by banning 
originating IP addresses after a few failed attempts.
