Hello folks, Yesterday, I presented for the first time [1] a new method to perform universal website hijacking by exploiting content filtering features commonly supported by corporate firewalls. I briefly discussed [2] the finding on GNUCITIZEN in the past without giving away the details, but rather mentioning what the attacker can do and some characteristics of the attack. Anyway, I'm now releasing full details on how the technique works, and a real 0day example against SonicWALL firewalls. The paper can be found on the GNUCITIZEN labs site. Please let me know if you can successfully use the same technique against firewalls by other vendors: http://sites.google.com/a/gnucitizen.org/lab/research-papers Finally, I'd like to thank Zero Day Initiative [3] for their great work and the Hack in the Box crew for organizing such a fine event! Regards, ap.
