Predator was written out of frustration from using Hydra, Medusa, Ncrack, Metasploit modules and Nmap NSE scripts for password guessing attacks. I opted for a different approach in order to not create yet another brute-forcing tool and avoid repeating the same shortcomings. Predator is a multi-threaded tool written in Python, that strives to be more reliable and flexible than his fellow predecessors.
Currently it supports the following modules:
* ftp_login : Brute-force FTP
* ssh_login : Brute-force SSH
* telnet_login : Brute-force Telnet
* smtp_login : Brute-force SMTP
* smtp_vrfy : Enumerate valid users using the SMTP VRFY command
* smtp_rcpt : Enumerate valid users using the SMTP RCPT TO command
* finger_lookup : Enumerate valid users using Finger
* http_fuzz : Brute-force HTTP/HTTPS
* pop_login : Brute-force POP
* pop_passd : Brute-force poppassd (not POP3)
* imap_login : Brute-force IMAP
* ldap_login : Brute-force LDAP
* smb_login : Brute-force SMB
* smb_lookupsid : Brute-force SMB SID-lookup
* rlogin_login : Brute-force rlogin
* vmauthd_login : Brute-force VMware Authentication Daemon
* mssql_login : Brute-force MSSQL
* oracle_login : Brute-force Oracle
* mysql_login : Brute-force MySQL
* mysql_query : Brute-force MySQL queries
* rdp_login : Brute-force RDP (NLA)
* pgsql_login : Brute-force PostgreSQL
* vnc_login : Brute-force VNC
* dns_forward : Brute-force DNS
* dns_reverse : Brute-force DNS (reverse lookup subnets)
* ike_enum : Enumerate IKE transforms
* snmp_login : Brute-force SNMPv1/2 and SNMPv3
* unzip_pass : Brute-force the password of encrypted ZIP files
* keystore_pass : Brute-force the password of Java keystore files
* umbraco_crack : Crack Umbraco HMAC-SHA1 password hashes
Predator is NOT script-kiddie friendly, please read the README inside predator.py before reporting.
