Is Our VPS Hacked Cpanel Hole?
Apr 24, 2007
I got an email from our rather new VPS server (all headers seem to show it's really from our IP) where an account was created by root and deleted 30 minutes later?!
Is there a cpanel loophole?
What should we do next?

After reading an article on command line FTP, I FTP'd to my VPS and was shocked out much access someone without logging in (and Anonymous FTP is off) has. I am running cPanel Release on CentOS 4 and Virtuozzo 3. How can I improve server security without giving any SSH access? I was all ready to use WebDav over SSL but then it doesn't allow you to change permisisons. Security is my #1 priority. My friend who I host says his clients like FTP and FTP is a standard service.
Would FTP with SSL be more secure, or still pose the same problems with sniffers and people connecting and being able to do something? Can I force FTP over SSL while not having cPanel over-ride my settings wiht an update?
What can I do to solve this major security hole? Next on my list is forcing POPs and IMAPs, authentication for SMTP and even SSL SMTP. Then only SMTP incomg 25 and HHTP port 80 would be none secure, but everything mostly secure.

My understanding is that currently the only way to protect against it is to deny any requests for PDFs where the request string takes that particular form? Is that correct? Or will the browser not even submit anything beyond the # sign in the request for the PDF?
And if it is correct.... has anyone tried to cook up a recipe that we can all dump in our .htaccess files to get this fixed up?

A client hacked another client of mine using the following Perl code:
#!/usr/bin/perl
symlink ("/home/john/public_html/config.php","/home/carole/public_html/forums/includes/config.php");
After the hacker got the DB name, username and password it's very easy to change anything in the forum using PHP.
I'm using cPanel.

I have just discovered a massive security in the CPANEL 10.9 software. This problem is in the BACKUP FEATURE. If you do remote ftp back onto the same account. It will put the file in the account home directory and it will have this type of stuff accountname:ROOTPASSWORD@serverhostname.com

I just got email from the company with which I co locate my servers (one of the resellers in MPT). The email said:
"We have detected a deny of service attack on one of your IP's
69.90.xxx.xxx. The attack was approximately 200Kpps and 120Mbps. The
IP has been null routed and will be in place for 24 hours."
Now all my sites hosted on that IP are down.
Is this the way the co location companies and their upstream providers deal with DOS attacks?
Its going to harm me a lot if I have to wait for 24 hours for the
services to work.

Just an FYI - we have been monitoring some attempts from europe. Here is a file that they were trying to include using a hole in PHPCoin's URL handler:
[URL removed] stringa.txt
The attempt was coming from linux.htd-information.dk

My cpanel is hacked. My server provide has given me the warning to resolve it in 24 hour or they will shut. I logged and removed text files from /tmp/
Now How should I find which domain was used for this?

Last night i checked the bandwidth usage on one of my sites, only to find a different last IP in cPanel, the person who did this changed my index page to a page saying it had been hacked, and changed all my moderators/admins ranks to a guest, so that means he has accessed phpMyAdmin too,
Im wondering if anyone knows anything that will help avoid future hacks, and also where i go about getting his ISP to remove his internet connection for hacking, I have a confession from him in email about the hacking, i have banned his IP from cPanel but anyone could change their IP, and i cant exactly ban his entire country from the server

I am renting a 384mb Plesk VPS, have 1 client website on it, and it was hacked. Someone set up a new user with root access and was attacking other networks including dictionary attacks. My host has cleaned up the mess. I suspect access was gained thru a weak password choice or thru a Wordpress hack.
The client website ran a php/mysql survey script sometimes with 20-25 simultaneous users, and about 5-10% were unable to complete the survey due to screen freeze up or time outs. I'm trying to get to the bottom of these errors and know that some of the problems were client side but could the attacks also have affected connectivity & website performance?

So how bad is it? have i been completely comprised or is someone managed to get some type of spaming access only?

I have a server with about 100 domains on it in Plesk. I have about 10 or so clients that pay me a pittance to host their site and the rest are various domains that have been parked.
About a week ago we received a "too many connections" error when accessing Plesk. This is our server and it sits at The Planet (formerly EV1). I cranked up the mx connections to 1,100 or so following some web tutorial but I'm really a complete idiot when it comes to this server stuff. (I'm more of a php / html kind of guy).
I check out logs and it appears that someone has been trying to access a bunch of celebrity images that shouldn't exist on our server. It's clearly spam of some kind. I can't seem to actually find these images on my server anywhere, but I've got a feeling that foul play has been involved.

Well, this is rather weird. I cant tell if this is a server error, or a hack.
Basically the contents of the thumbnail directories for videos, games and pictures were deleted, at 3pm today (according to the ftp time stamp). All those folders were chmodded 777, to allow PHP to upload the images into them.

My cpanel server has an intruder who brought all the sites down. I did my best to harden the server a year or so ago, but...
I got an email from one of my scripts:
SUBJECT: [hackcheck] kill has a uid 0 account
IMPORTANT: Do not ignore this email.
This message is to inform you that the account kill has user id 0 (root privs).
This could mean that your system was compromised (OwN3D). To be safe you should verify that your system has not been compromised.
To say the least, the server was compromised. I cannot find the user "0" or "kill" in WHM, but under "Wheel Group Users" "kill" is listed under "Add a user to the wheel group."
Any help or insight would be appreciated! Anyone proficient at hardening servers and exorcising hackers?
I uploaded the latest chkrootkit and ran it. The results say it's clean.

I have a new server and I have hardened it with csf+lfd. It's about 65/70 in the cfs score.
This morning, I noted that lfd log sent me an email saying there is a SSH login via 207.210.233.128 on 10th May 2007. I am not sure whether it was a successful login or not?
Here is the output:
=================
Time: Thu May 10 01:31:52 2007IP: 207.210.233.128 (Unknown)Account: rootMethod: password authentication
========================
I know for sure that I did not login my SSH yesterday.
However, when I logged in SSH this morning, it says in telnet that my last login was from my own home computer's IP, so from that it looks like no one else has logged in SSH since last time I logged in myself.
Was my server intruded or was lfd just playing up?

I have a VPS running cpanel/whm on CentOS.
Everyday someone keeps coming in and deleting all my accounts. I do have them saved, but I cannot figure out how they are doing it.
I have followed the tips on the forum for locking down VPS. We have restriced SSH logins to our IP, we have checked all directories for ones that are 777 and changed them, we have moved the server to a different IP address.

So I'm interviewing with a company and when I typed in the URL to their website, I was met with a nasty surprise: a "hacked by so and so" message! However, after looking closer, I see that I had accidentally appended a period (".") to the end of the domain name, for example: http://www.example.com./
When I removed the period, the site appeared as normal. I don't know anything about the server other than it's IIS. Is there anything I can suggest to them when I go in to interview? I'd like to point this out to them; it may even help my chances at landing the job! (It's not related to networking, though.)

Now, first of all... I'm not sure if this is a problem with WHMCS or some other piece of software with a security hole, but I thought I should post here.
Our WHMCS got hacked earlier today and the hacker sent out a to be honest, unacceptable email to all clients, I won't go into detail but lets just say it directly insulted them.
Now apart from ruining our reputation and client relationships, I am now completely paranoid that it will happen again. I'd also like to know how it happened in the first place. The hacker signed up for a hosting account, and then sent the email. I have no idea how he/she did it, but when I look at the admin log in WHMCS, it shows the username "hacked" as logging in (see image).http://img378.imageshack.us/img378/2560/hackedmh9.png
Just a warning to everyone out there. His IP address was 86.132.228.82.

A client's site was hacked last week and spyware or some kind of trojan was put on it. I found some files that didn't belong in the images folder and proceeded to delete them, however, when I submitted the site back to Google for review, the report came back saying there was still malware on the site. They didn't provide me with the location of the spyware, so what can I do to find it and delete it?

we have a vps server and someone did what I would call a calling card attack, thankfully.
It is a stock kubuntu os with stock apache. Root passwords for everything have been changed to our own
Somehow they logged into kubuntu as root and changed the htpasswd in usr/passwords (changed to protect the password).
Then since they changed the htpasswd they were able to log into phpmyadmin and changed the admin password in the database.
I'm pretty sure I know who did it and he is teaching us a lesson which I respect but he will not comunicate with us.
We have hourly snapshots of our vps and we need to know how they are getting in. See my sig and click on the hotspot login.
Looking at the sudoers there is the Defaults line that we suspect as a means to get in.
We have a great php etc... app but it is either Apache or kubuntu that they can get in.
I would like to learn about what needs to be done about security but where do I start?
Can someone help me look for something that would allow the attack?
I'm a php guy and it is not a mysql injection attack nor is it an xss attack.
I am not a kubuntu / server security guy and now need your advice.

Out of the three websites that were hacked the hacker left a get.php file in the root and i decided to see what it was and i ran it. To my shock and horror it gave me all the different types of people hosted on the server and it also gave me their database passwords etc...
Now each time i ran it, it gave me different results of different users on the server each time with a long never ending list. I just couldnt believe my eyes a simple short written php script showed me a lot.
Now im not a PHP guru but this is quite serious and ive notified my web host showing them my findings. I was quite astonished it showed me passwords in peoples configs.
Now my question is... is this something new or old and that my web hosts forgot to look into that area...? I mean its a php script thats all.

One of my clients has just sent me a bounced email to an address she had never heard of. This made me suspect my server had been hacked and was being used for a scam.
Sure enough, I found a file in one of my folders, that was related to a Bank of America scam.
I have since put a password on this folder. But does anyone have any advice on how to secure the site to prevent this happening again? It is a shopping cart and the 'rogue' file was in the admin area of the shopping cart.

SOme one has claimed that he has penetrated my server and has gathered some kind of information via shell access, I have disabled the possible ways of shell access for the users via twaek settings, and php.ini
- How I can check he has made any backdoor for himself or not?
and I have made a trojan check via Scan for Trojan Horses in WHM, and it has found about 200 possible trojans.
