I recently posted a hacker challenge that consisted in a vulnerable login form, and specifically the vulnerabilities was found in the way the cookie was set, well for this tutorial I’ve decided to do a basic introduction to the mechanics of login forms and cookies in php using mysql as the database backend. On the application side, you can use cookies in you PHP scripts to control access to certain areas of your web site. A cookie is a small amount of data stored by the user’s browser in compliance with a request from a server or script. A host can request that up to 20 cookies be stored by a user’s browser.

Ok, by now you probably now how much I enjoy hacking, ehm, ehm…sorry!, pentesting. Well for this tutorial I will be pentesting MS SQL Server with SQLat, Freetds, and Cain. Database store and provide access to information and information is power. Sensitive data such as bank account numbers, credit reports, and lots of other important information can be obtained from an insecure database, in this tutorial I will try to explain basic technology about MSSQL, like default install as well as demonstrate tools and techniques that can be use to exploit MSSQL server.
In this tutorual will go over the most useful netcat commands. Netcat is a tool that every IT professional should have in their tool box, if you’re responsible for network or systems security, it is essential that you understand the capabilities of netcat. The original version of netcat is a UNIX program. Its author is known as Hobbit. He released version 1.1 in March of 1996. Netcat is available for Unix and Windows OS.
Netcat is a featured networking utility which reads and writes data across network connections, using the TCP/IP protocol. It is designed to be a reliable “back-end” tool that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities, including: port scanner, backdoor, port redirector, port listener, and lots of other things….Let’s see what we can do with netcat.

This is a demonstration of how easy is to sniff a remote computer internet connection in real time, for this I will be using open source tools like ettercap and dsniff’s webspy, because in a real world scenario all computer in a network are connected to a switch, network traffic is not redirected to every port on the switch therefore in order to see the traffic between our victim computer and the gateway, I need to implement ettercap’s ARP cached poisoning to successfully capture data between the two host.
