VoIP Hopper is a GPLv3 licensed security tool, written in C, that rapidly runs a VLAN Hop into the Voice VLAN on specific ethernet switches. VoIP Hopper does this by mimicking the behavior of an IP Phone, in Cisco, Avaya, and Nortel environments. This requires two important steps in order for the tool to traverse VLANs for unauthorized access. First, discovery of the correct 12 bit Voice VLAN ID (VVID) used by the IP Phones is required. VoIP Hopper supports multiple protocol discovery methods (CDP, DHCP, LLDP-MED, 802.1q ARP) for this important first step. Second, the tool creates a virtual VoIP ethernet interface on the OS.

WebGoat is a deliberately insecure J2EE web application designed to teach web application security lessons. In each lesson, users must demonstrate their understanding of a security issue by exploiting a real vulnerability in the WebGoat application. For example, in one of the lessons the user must use SQL injection to steal fake credit card numbers. The application is a realistic teaching environment, providing users with hints and code to further explain the lesson.
Web application generally at the hit list of hackers and different hackers use different technique to find the bug (vulnerability) on web application to get the root access or to steal some information. Web application vulnerabilities like SQL-injection and cross site scripting are dangerous for web but as a penetration tester you need to test the security of a web application first step to hack or secure is to map the over all infrastructure, so golismero is wonderful tool that play the role to do this.
Ncrack is a high-speed network authentication cracking tool. It was built to help companies secure their networks by proactively testing all their hosts and networking devices for poor passwords. Security professionals also rely on Ncrack when auditing their clients. Ncrack was designed using a modular approach, a command-line syntax similar to Nmap and a dynamic engine that can adapt its behaviour based on network feedback. It allows for rapid, yet reliable large-scale auditing of multiple hosts.
SQL injection is the most common and most dangerous web application hacking technique in SQL injection a hacker take advantages of misconfiguration and poor coding of SQL. SQL injection will take an attacker to the important database that might contain credit card information, administrative information and more. There are so many tools are available for SQL injection, you can use w3af, nikto and others to find the sql vulnerability on a web application. Backtrack 5 also contain so many tools like sqlmap.
