Want to hack a LAN? Well, hacking local area networks is easier than you'd think. And by watching a few short videos, you can become a master hacker, something every techie wants to achieve. And what's the best way to hack a LAN? Ettercap, a password sniffing program.
The program can easily sniff out LAN passwords, and can recognize several different packets that contain passwords. Some of these include HTTP, Telnet, FTP, POP, rlogin, SSH1, ICQ, SMB, MySQL, NNTP, X11, IRC, IMAP, VNC, SNMP, MSN, YMSG, etc.
Also, if you know what "man in the middle attacks" mean, then you'd be happy to know that Ettercap can do that, too. It hijacks packets, redirecting them to the attacker's computer, allowing it to extract the secure LAN passwords. This particular six-part video will outline how to use ARP Poisoning, also known as ARP Spoofing, ARP Flooding and ARP Poison Routing, and it's used to attack both wired and wireless networks, letting you (the attacker) sniff data frames over the LAN. You'll also learn about DHCP Spoofing, Port Stealing MITM Attacks, and using Ettercap to sniff encrypted passwords over the Secure Sock Layer (SSL; HTTPS).
Also, learn how to use Ettercaps plugins, like Check Poison, Re-Poison, DNS Spoofing, Isolate, DoS Attack, Find IP, Gateway Discover, Search Promisc, Arp Cop and Scan Poisoners.
