How To Find Out Hacked Files On Server

Jul 10, 2009

My server was being hacked, I can find some HTML and PHP files which inserted the codes similar to the following by the hacker.

HTML Code:
<iframe src="" width=125 height=125 style="visibility: hidden"><
The inserted iframe src is not the same among the hacked files.

I am trying to find out all the hacked files on server, is there any way instead of checking the files manually?

Uploading Files To Server

Nov 9, 2009

Why is it that you can upload large file size when you are using FTP, but you cant upload large file size beyond the max when you are using browser to upload?

People Uploading Much Bigger Files To My Server, That I Want (using Php)

May 13, 2007

i have free hosting server and a rule to upload 3MB file max. it works for FTP, but somehow it doesn't work for php. It seems for php the limit on my server is 100MB (no idea why)

i use following directives to limit file size in php.ini :

; Maximum size of POST data that PHP will accept.
post_max_size = 4M

(4 just for some margin )

; Maximum allowed size for uploaded files.
upload_max_filesize = 3M

and i still can find 100MB files on disk. this is part of log file from apache from the account that uploaded it to me:

boorako.[] someip - - [13/May/2007:12:21:22 +0200]
"POST /a/redir.php?capthatag=accesscode&saveto=&path=/some/path/boorako.[]/a&comment=&domail=&email=&useproxy=
HTTP/1.1" 302 188

boorako.[] someip - - [13/May/2007:12:21:35 +0200]
"POST /a/redir.php?capthatag=accesscode&saveto=&path=/some/path/boorako.[]/a&comment=

HTTP/1.1" 302 188 [url]
"Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv: Gecko/20070309 Firefox/"

as the effect of this (at least i think so), there was 100MB file in his home dir.

any idea how can he POST such big files even with those two directives?

i have also set LimitRequestBody to 5194304 and LimitXMLRequestBody to 5194304 in apache2.conf which also should stop files being POSTED as big as 100MB.

i have php 4.4.4-9, Linux Debian, apache 2.2.3 working in worker mpm, and php as fastcgi.

P.S. i removed server info like IP, dir and address to not show specifics about my server in public, i put [] there.

Windows Server Hacked And Files Transferred Using Torrent Clients

Nov 8, 2007

I have noticed in a few Windows server tha the server gets hacked and there are tons of files which are mostly DVD rips and games being transferred away which results in huge amount of data transferred and bandwidth consumption increasing to as far as 29 Mbps. On further investigation, I find that all the files get stored in either the Recycler directory or the System Volume Information directories in any of the drives. Now these two directories are protected operating system files. Even if there is a windows firewall installed, there is no difference. I have even noticed that in some servers there is an automatic exception rule added in the windows firewall enabling the torrent client to communicate outside the server. This seems to be a common problem with Windows 2003 server and seems to be some backdoor of Windows allowing hackers to use the server for seeding. Has anybody come across such a problem or know the solution? Kindly help me with this.

Uploading Files

Jan 28, 2009

I've just uploaded my website files onto the server, the website is working fine, but I'm not sure my files are 'arranged' right. I uploaded my images in a folder, but all the rest of the files are 'loose' along with the index file. If I go to either of my domain names, the website appears, which is ok for now, but I only really intended it to under one domain name, so there may be problems if I want another site up there. I think my files should be in a folder. Is this right? Should the index file be in the same folder, or should it be outside the folder with the links changed accordingly. I've been emailing my hosting service, and they 've been trying to help, but I feel a bit thick because I don't really understand what they're saying. Could someone tell me in very plain english how the files should be arranged?

Uploading Files Through CMS After Moving To New Host

Jul 18, 2009

Hi guys, I've been having problems trying to edit my php.ini file which I think I've now fixed.

The whole reason I wanted to do this was because I've just moved to Media Temple from another hosting company and I'm having a couple of problems with the switchover.

Basically I use a CMS system to add properties which appear on the main website. I also upload PDFs and images. On the old hosting company, the PDFs and images went into folders called dnDir/pdf and dnDir/images but on Media Temple, they are going in to a folder called tmp. I really want them to go to the same place as they used to.

Is this an issue with php.ini that I need to rectify? If so, could you point me in the right direction?

Prevent PHP Files Used For File Uploading

Jul 3, 2009

It appears that some people like to take advantage of those files for online web applications such as Wordpress which have php files with permissions set to 777. They use those as a means of creating an upload file. The upload files that they create then have access to the whole server somehow... Is there anyway of preventing this from happening?

FTP Timing Out When Uploading Small Files

Jul 20, 2009

There is a behavour with my server FTP when uploading a whole directory with many files in many sub-directories

Very often, the server disconnect itself when actively uploading files and the log simply says 'timeout'

It is as if the file got 'stuck' half way, and the FTP consider them as idle, therefore it disconnect you with a 'timeout' before reconnecting you.

But i have no problem uploading a single 200mb file to the server via FTP. I suppose no problem with 'keep alive'

So what is this behavior and how to solve it?

FTP :: Stop Uploading Large Files

Jul 17, 2008

I'm facing a very strange FTP issue with one of my shared-hosting accounts, while all of my other servers are having no problems but only this one, when I try to upload a file (whatever file) larger than 500kb from my local PCs, in most cases, the file would stop uploading during the process and hang there until it times out.

There are 2 interesting things though:
The file transmission typically hangs when approximately 248kb of the file have been transferred, pls see the attached screenshot for example.

If you look at the attached screenshot, you will notice that the uploading transmission hangs when 248kb of the file have been transferred. This is very strange and what I mean is that for example, I randomly pick up a file, and attempt to upload it onto my host for 10 times, now see, 5 times it will hang when 248kb of the total size have been transferred, 3 times it will hang at other points *near* 248kb (224kb or 280kb typically), 1 time it will hang at another random point, and 1 time it might be uploaded successfully (yes, there is still a tiny chance for the file to be uploaded successfully).

My default internet uploading speed is 80kb/s-100kb/s, lately I found that, when I limit the uploading speed on my FTP client (e.g. max. 30kb/s), everything WILL WORK without any problem! No hangs, no interrupt.. Whereas when I free up the uploading speed limitation and let it upload with my regular speed, the problem appears again.

It seems to me that the FTP hangs only when the uploading speed is higher than 60kb/s. However my host provider told me that they have customers uploading without any problem at over 400kb/s, and they said "there's no problem or limitations on the server at all".

Up until now, I have done following things to troubleshoot the issue but with no luck:

Contacted my host.
Disabled/Enabled the PASV mode on my FTP client.
Tried different FTP clients on different computers (FlashFXP and Filezilla).
Rebooted my router and reseted everything with the factory default settings.
Contacted my ISP for the issue, they "did something" but nothing were helpful.
Rebooted all my PCs.
Disabled both firewalls on my PC and on the router.

Furthermore, I have asked another friend of mine in another city with another ISP to test the FTP uploading, but unfortunately he got the exact same problem. And I've done some search on the internet for hours but no one seemed to have the same problem..

So can someone guide me at this? Specially the one who has hosted some page at Frihost.

May 6, 2009

Sometime ago the DC told me there was too many files on server and I started to investigate what is was and i got info that some one hacked the server and was sending spam from it.

Can I detect that somehow?

Is it possible to do some small script to detect this?

Is there any advanced module to DA that gives me the info?

Server Hacked ...

Apr 7, 2007

My server was hacked some time ago. I've changed passwords and scanned system for viruses, but found nothing.

Now, I'm looking into the log file /var/log/messages and I have few questions:

1. There are a lot of messages like: Apr 2 02:53:09 host
sshd(pam_unix)[29398]: authentication failure; logname= uid=0 euid=0 tty=ssh
ruser= rhost=

Do these messages mean that hacker trying to enter the server under root?

2. There are messages like these:
Apr 2 03:56:10 host clamd[4678]: stream 1255: Worm.SomeFool.P.2 FOUND
Apr 2 10:46:10 host clamd[4678]: stream 2008: Worm.Bagle.pwd-eml FOUND

What does this mean? Virus on my server or something else?

3. Also, I can see a lot of messages like this one:
Apr 2 09:38:40 host clamd[4678]: stream 1111: Email.Phishing.RB-524 FOUND

Does someone read my emails?
