metasploit + dns_bruteforce

auxiliary/gather/dns_bruteforce 模块可以用于暴力猜解dns.


msf > use auxiliary/gather/dns_bruteforce
msf auxiliary(dns_bruteforce) > set DOAMIN www.example.com
DOAMIN => www.example.com
msf auxiliary(dns_bruteforce) > set WORDLIST /path/to/wordlist
WORDLIST => /path/to/wordlist
msf auxiliary(dns_bruteforce) > run



使用时，可能会提示下面错误:
