Sniffing Remote Router Traffic via GRE Tunnels



A good demo of sniffing network traffic remotely via setting up IP tunnel interface on remote router using WHAX live distro. Attackers makes configuration changes on router to start a tunnel interface and route all of the network traffic from that tunnel interface. Later they can sniff the traffic when ever they wants.

Windows SMB Relay Exploit



A live demonstration of obtaining admin access on a Windows XP SP3 Machine. Exploits a flaw in Windows Server Message Block (SMB) which provides shared access to files and folders on network.

Honey Pots



Honeypots are the machines used for intrusion detection.It's basically a trap for hackers and seems to contain wealth of information in which hackers are interested in.

These computors are configured with lots of monitoring tools which keeps an eye on each and every step of hackers which helps in studying their mind set later on. Softwares installed on these computers are dual purpose.At first glance they are inviting in nature, intruders gets attracted to them and on the other hand it helps in intelligence gathering.Once the hacker breaks into the system,later studies of these machines by security administrators helps in finding the ways which attacker used to break into these systems and helps in blocking those intrusion techniques.
