Overflow Concept [ by : Mohamed Ahmed ]

Forum Thread: Spying on Segmented Networks

Network segmentation using Switches seemed the perfect solution to avoid the dreaded sniffers. But all that glitters is not gold and it is possible to take advantage of an insecurity in the ARP protocol to spy on the network. In this article we are going to explain one of the techniques used to sniffing in a network segmented through Switches: ARP-SPOOFING.

Forum Thread: Port Knocking

Introduction to Port Knocking In computing, port knocking is a method used to open ports on a firewall by a set of connection attempts launched over closed ports. When the correct connection sequence is received on the server, the firewall rules are modified dynamically to allow the host that sent the packets to connect to a specific port (s).

Forum Thread: Authentication Attacks

Spoofing-Looping Spoofing can be translated as "posing as another" and the aim of this technique is precisely to act on behalf of other users, usually to perform Snooping or Tampering tasks. A common form of Spoofing is to get the name and password of a legitimate user to, once entered the system, take actions on behalf of him.

Forum Thread: Disabling Buffer Overflows protections by Mohamed Ahmed

Disabling Buffer overflow protections When it is time to scan a program for vulnerabilities or just exploit them under GNU / Linux, there are two simple protections that you should keep in mind when it comes to systems with Kernels version 2.6 and higher , and over all if compiled with GCC. There are more protections such as the patch grsecurity or exec-shield (of which I may speak later), even there is protection from hardware called StackGuard .

Forum Thread: Getting Connected to Wifi in Kali Linux VirtualBox

I am trying to connect to a wifi network in Kali Linux using Virtualbox. I am using the "Bridged Adapter" network setting. At my house, I can get an IP that is on the network and can be pinged from a separate computer. I also tested it in another location on another wifi and I can get an IP that is on the network. For some reason in another location with WPA2 Enterprise Wifi I can get connected to the internet, but I can not get an IP. After running the command "ifconfig" in the "inet" field ...

Forum Thread: Getting Client IP for MITM

Hi guys. I've been reading a lot of the tutorials here recently and decided to try a simple MITM attack following the first tutorial in the series. It's easy enough but got me thinking if it's any good for a real attack when I am not on the same LAN as the target. Anyone know a way to get the client IP in that situation? Thanks all :)
