Hack Attack The Networks With Yersinia

Yersinia is a network attack tool that takes advantages of inherent weaknesses of several protocols to attack the network using different attack vectors. Yersinia can prove as a solid tool for analyzing and testing the deployed networks and systems for possible weaknesses.

The protocols implemented for testing using Yersinia are:

• Spanning Tree Protocol (STP)
• Cisco Discovery Protocol (CDP)
• Dynamic Trunking Protocol (DTP)
• Dynamic Host Configuration Protocol (DHCP)
• Hot Standby Router Protocol (HSRP)
• IEEE 802.1Q
• IEEE 802.1X
• Inter-Switch Link Protocol (ISL)
• VLAN Trunking Protocol (VTP)

Yersinia supports number of attacks in all of the above listed network protocols and hence can be used (or misused) to test any network.

The tool works on several operating systems such as OpenBSD 3.4 (with pcap libraries >= 0.7.2), Linux 2.4.x and 2.6.x, Solaris 5.8 64bits SPARC, Mac OSX 10.4 Tiger (Intel), etc.

Installation on ubuntu: Fire up the terminal and type:

sudo apt-get install yersinia
