Hi, we are pleased to announce the release of Yersinia, a framework for (mainly) layer 2 attacks. The tool has been presented in BlackHat Europe 2005, so if any of you could attend the conference will know what it is about. Yersinia implements several attacks for the following protocols: Spanning Tree (STP), Cisco Discovery (CDP), Dynamic Host Configuration (DHCP), Hot Standby Router (HSRP), Dynamic Trunking (DTP), 802.1q and VLAN Trunking (VTP), helping the pen-tester in different tasks, e.g: - Becoming the root role in the Spanning Tree - Creating virtual CDP neighbors - Setting up rogue DHCP Servers - Becoming the active router in a HSRP scenario - Enabling trunk - Performing ARP spooing over VLAN Hopping - Adding/deleting VLANs (via VTP) - more.. It is a multithreaded application with three main modes: command line, network client and ncurses GUI, allowing multiple users to launch multiple attacks simultanously. Besides, you can decode some Cisco propietary protocols like DTP or VTP!! You can download it from http://yersinia.sf.net and send your doubts, questions, bugs or greetings to yersinia () wasahero org. Best regards and happy trails:) David Barroso Berrueta Alfredo Andres Omella
