Hello chaps!!
I am currently investigating the double tagging attack in order to prevent my network of possible security flaws.
The attack concept seems quite straightforward. But I am unable to launch the attack successfully so I began to think that Procurve Switches have a kind of inbuilt security for this kind of attack.
I have been testing the attack using Yersinia and 2 lab Procurve switches with the default configuration plus the required vlan configuration to simulate the attack.
Any thoughts on the matter? Has anyone here performed a successfully attack against Procurve switches using this technique?
Thanks for your help.
