IntegraMOD

Hey guys,

I found something rather disturbing in my backup directory of my php site today. It was a php script that allows anyone access to the backdoor of my site. It is called "musa.php". I did a search of google and of this Integramod2, and didn't see it mentioned anywhere. I am not sure how to block it other then to disable the backups (which I don't want to do, but would rather do then have an unsecure site).

BTW, the only way to remove it seems to be to use it to remove itself.

Anyway, here is the header of the code for the hack with the hope someone can block it.

hi

We are looking into it

Y'know, I had this on mine, as well. Out of curiosity, jwernerny, who's your web host?

I found the file.

This is an other stupid "BackDoor Shell Exploit"

I am with WB-Hosting now. I did read something that suggested it could be cross loaded from another site on a shared hosts.

I have it! I deleted my backup directory in entirety until I know what is going on. It has been there since April Fool's Day (seriously) and had edited all of the PHP files in the backup directory, according to the time stamp. However, according to the translation above, it has the ability to inject files and not change the timestamp. I am super-paranoid at this point. Should I be changing my passwords for IntegraMOD and/or my server host? Is this a destructive trojan or is it fishing for sensitive information. Help!

Has anyone else found this file on their server? The file and the modified files were all stamped April 1st on my server. Is this a joke or a coincidence? It seems strange that there is not more information available. I am going to upload my backup directory from scratch again and keep an eye out. Any advice?

I have not.....

Any developments? I managed to delete the file and it has not reappeared for two weeks, but I am naturally concerned that security has already been compromised.

was in mine to, check your root folder (/) of your host it had put a file there, so i deleted it and musa.php
