It's a program that injects a dll file into the memory of a firewall. It's some what like the cheat injection to hl, but in a different form. I liked reading it.

Looks like this only applies to Sygate, Symantec, McAfee, TinyPersonalFirewall, and Kerio personal firewalls. An enterprise or soho-based firewall like Firewall-1, PIX, Raptor, or even the little Linksys systems aren't affected. It's an interesting attack but it's not one that's impossible to defend against. If the pfw's did a runtime hash of the code in memory it would be defeated. Also, it doesn't work if you're not logged in with administrator priviliges. Most people running NT/2K/XP based systems do this for convenience, unfortunately.

I think it's a hack that would be used with spyware and trojans applications, and not on against big companies. It is like the trojans that hijack internet explorer. It does work against more firewalls, such as zonealarm. If you read that thread all the way through, the guy reversed it and made it work with ZA. I'm not too sure how a linksys, or soho firewall could prevent this, but all you would need to do in any case is block the firewall itself from accessing the internet.
