Well what a motto.. If you do get hacked again then its not an image gallery.. we have rulled that out then. Shocked

Right, i've removed all galeries, and any upload module (except for attach_mod in phpbb. don't tell me this one is suspected too!).

Hate to tell you but it very well could be the attachentt mod..

Dont go removing it just yet tho..
Heres a few tips. Find out how the hackers found your site.. By checking your webstats.
And then if you do find something odd then you may have your answer.

But hackers are odd you know.. You never know how they find your site.
Check over your server logs for that time when it was hacked, shouldnt be too had to pin point..

Its just a stab in the dark, im totaly guessing about the attachment mod.. It could be anything these days. You never know. Rolling Eyes

Look for a URI Requet String (values after the ? mark) that have something like

file=index.php

Raven, what about the error i get with the patched admin.php, as i wrote in the 1st page?

Raven · Posted: Fri Jun 04, 2004 5:10 am

No idea at this point. I would restore your files, disable all addons/apps that have file upload capability, and search your logs as I stated above. That will tell you how they are getting in.

Raven, I had a problem with the FIRST file I've uploaded. Sad

I've started with the root's admin.php file. after replacing (don't worry I have a backup) the file, i got this error:

Fatal error: Call to undefined function: stripos_clone() in /home/hagigim/public_html/admin.php on line 19

Now I'm realy afraid to continue...

The first file you should upload is mainfile.php

That's what I thought too... so I've uploaded the admin directory plus the index.php, mainfile.php and other root files. with no vail...
So I removed the patched admin.php and now using the old admin.php.

Look at the lines that start with 200. First, these are Brazilian IPs << notorious for hack attempts. Second, if you look at these lines closely, they are using a vulnerability in your 4nAlbum module to access a file on another server. They are then using http :// failiture.webcindario.com/rf.txt to execute commands on your server.
I don't use 4nAlbum myself, so I cannot direct you to updates. But I would bet that the problem in this instance is 4nAlbum. Hope that helps.

BTW, I took a look at that rf.txt file; here's what's in it.

Code:

Thanks, oprime2001.
I've removed 4nAlbum on Friday already.
Do you think I should also ban Brazilian IP from accessing the site?

Oh, and how can you tell wether an IP is Brazilian or other?

I use

to help identify visitors. You can also use IP-to-country databases (e.g.

) if you want to check specific IP addresses.

As for banning all Brazilian IPs, that's up to you. After getting defaced twice in one month from Brazilian IPs, and since my sites are not geared towards Brazilians anyways, I've personally banned all 200. IP addresses using .htaccess file. Hope that helps.

Could you please detail how one should do it in the proper manner?
TIA!

Add this line to .htaccess
