If the page is garbled, then the message of the website is not renamed and can be invaded.

STEP3 inserts an ASP back door in the database

I mentioned the message of the news system. This plugin is not strictly filtered, so we can insert the "one word trojan" server code by submitting the statement in the database:

Access "http://www.qswtj.com/news/khly.htm" in the browser and open the submit Message page. In the submission page in the "Home" column, directly fill in the "one word trojan" service side code, other casually fill.
