Hi all
Thesedays I'm analyzing the solarys system that using apache web
server and php. Of cause it hacked.
I could not find reason of some situation that the specified directory
are created over and over(it includes check.js)
Weblog record as below
> > xxx.xxx.xxx.xxx GET "/XXX/ahibix/check.js
Some pages can upload the file but it didn't work when I uploaded some php file.
I'm wondering how it makes some directories.
Any suggestin,ideas.
Thanks all
