My server (using plesk 8.1 on windows 2003 server) has been compromised with some sort of rootkit and I'm investigating vulnerabilities. This server hosts some of my asp.net applications and I have to grant Modify Permission to IIS WP (iwam_plesk) user on Some subfolders (under Httpdocs folder for each domain). Is it a security problem? if yes, how else can I allow asp.net applications to write to, say, an Access db?

I included some log snippets to help you make sure your account hasn't been compromised.

I can resolve this situation I have.
I sent a server I have with a provider to have a RAM upgrade yesterday at 15:33 UTC, and ever since then I have had no access to my server.
SSH has been changed back to port 22, from a random high port.
root password has changed
RSA key has changed too.
I can see 3 possable reasons for this:
1) It's a different server plugged into the rack/router or a stolen IP
2) My provider "kindly" formatted and reinstalled my OS.
3) I have a compromised server, I very much doubt this as the server was offline.
I informed my provider about 18 hours ago that I had a "possable compromised server" and since then I have been given the run around as to what is happening.
For the last couple hours or so I have been trying to get them on live chat, which shows as online, but no-one answers. Thats another pet hate of mine.
I also have a couple tickets open asking for an update as they are not answering my origional ticket with updates.
Am I just being impaitent wanting a resolution to this in less than 18 hours or am I correct to complain?
I am trying to determine if i am hacked, here is details:
I just got a message from softlayer support: ABUSE - 66.228.xxx,xxx - HACKING/MALICIOUS ACTIVITY - IMMEDIATE ACTION REQUIRED. with some log like this:

So does that mean my server was compromised?
Linux Fedora 5
I just got a letter from my dedicated host stating we had just been compromised. These servers just were set up last week! And there is nothing on them yet. The only thing I have done is modified the /etc/hosts file via SSH.
My servers are not even public yet. Can SSH'ing in from an unsecured wireless network make me vulnerable?
What do you guys think? Best way not to let this happen again?
Oh this is great :-| He's still logged in!

one of the worst things (in hosting) has happened. I received a notice this morning from lfd (configserver) that someone had logged into my server as root and it wasn’t me.
Unfortunately I didn’t notice it until eight hours later so I have no idea (yet) what happened during that period. Thankfully I don’t have any really critical data on the system that could have been stolen.
I’m in the process of restoring from a full system backup right now. After that’s done I’m going to look to see what the differences are between the files from the backup and that on the comprised drive. I’m not sure if I’ll get anything useful from the diff but hopefully I’ll find a clue as to how they got root access.
Then of course I need to get my server back up. However, I don’t want to do this until I’ve taken some steps to identify how the individual got in and take some additional preventative steps.
Here’s what I am planning on doing:
1) Check to make sure all exposed services are patched and look at some security sites to see if there are any known vulnerabilities for these services. Anyone know which sites are good to look at?
2) Change firewall to only allow ssh access from a couple specific IP addresses.
3) Disable root ssh access so I have to login via a different account and perform sudos, etc.
4)?
I’ll also look for a good server-hardening guide to see if there are some obvious things I forgot to secure.
Do any of you find folks have any other suggestions or resources that I should check out?
My windows server 2003 server password has been changed. My host tells me they must reload the entire OS in order to fix it..
Is there no way they can go in and rescue my server? Would save me alot of work.
So one of the sites on our box was compromised earlier today.
We've shut it down for now and contacted our sysadmin to help research the problem. Not sure if he will be able to really help much as he's only done updates and such in the past.
Any idea of quality sysadmins who might be able to investigate the box and the site?
I have been trying to troubleshoot our Windows 2003 server for weeks, but have made no lead way. The following are the steps they take to breach the server.
“They” are able to create an account. Some used usernames they have created are: sysadmin, adm, mssqladm.
It is very odd, looking in the event viewer, they just appear to create accounts out of the blue, they don’t even login or attempt to login or anything, all the sudden it says, New Account Created.
“They” then change the password of the account they just created.
Then “They” assign themselves the following group permissions, ‘Users’, and ‘Administrators’. ** SHAKING MY HEAD ** How the bloody hell do they assign themselves Administrator rights?
Then the do a few different actions depending, often times they disabled the windows firewall, and change open ports, other times they simply just logoff, other times, they have placed Trojans horses and other malware in their temporary internet folder under their use folderr.
This has been a cat and mouse game for weeks, I catch the new account, and immediately delete it, and check the firewall and enable if needed, then run a full system scan with AVG and Prevx. Sometmies AVG finds Trojans and malware, other times its clears.
I have racked my brain, checked all running processes with google, and they are seem legit. I have updated everything in windows via windows update, we are running windows 2003 server SP2. I have looked at the users and groups and everything seems secure.
Do you have guys have any idea what is going on? I have feeling something is running internally, which is allowing them to create the accounts.
Is there a tool that tracks all currently running processes, and allows you to go look at the logs to see what exactly was running at a certain time?
To automate some tasks for some projects I'm working on, I need to be able to automatically create or delete ftp-users.
Creating and listing ftp-accounts is working great, but when it comes to deleting them I run into an internal server error. Before my script gets the response it's waiting for, the script crashes.
- When live watching the Apache error-log with 'tail -f', the terminal-session is exited with 'Killed (core dumped)'
- Apache error-log shows:
Code:
(104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: http://example.com/ftp.php?action=delete
Premature end of script headers: ftp.php, referer: http://example.com/ftp.php?action=delete
- Webbrowser shows default '500 Internal Server Error'
I have checked and changed time-out settings, but it didn't work. Error occurs a few seconds after executing, while the timeouts are set to 60 to 90 seconds.

when I find the subscription from the admin side of PPA, if I select "Login as user" I've noticed that it is different from actually logging in as the user - for example - "add domain alias" is missing when I login as a customer - but not as an admin... I need my customers to add their own aliases and manage them - how do I add that feature to the client login side?

So far I have confirmed that a script is using PHP to send mail out bypassing the MTA. It is faking the HELO and impersonating a well known ISP.
I used a combination of tshark and netstat. tshark can show me the HELO and EHLO. When I see the wrong entry I cross check that with netstat to see what. So Netstat only shows that it was PHP not the script path.
Here are the commands I'm running:
Code:
nohup netstat -c -p -n -e | grep -i ":25" > /var/log/monitor/netstat-smtp.log &
nohup tshark -f "port 25 and src host XX.XX.XX.XX" > /var/log/monitor/tshark-smtp.log &
Then I grep for what I'm looking for:
grep -i "HELO" /var/log/monitor/tshark-smtp.log
Is there a way to get Netstat to show the script path or complete command that is establishing the connection? Currently these scripts are eating up memory to a point that other process or getting killed off.
I also tried to force all mail through the MTA, but When I enable SMTP_BLOCK in my firewall config I get and error:
*WARNING* Cannot use SMTP_BLOCK on this VPS as the Monolithic kernel does not support the iptables module ipt_owner - SMTP_BLOCK disabled.
If there is a better way I'm game. Maybe some IDS that can tell me more of what is going on with the server?
I have read many helpful feedbacks regarding choosing a reliable web host. Most of the concerns are centered around costs. However, I am more particular about the relative security of my website in addition to other perks such as space, speed and bandwidth. I rate my concerns on a 1-10 scale:
Security 9/10
Bandwidth 7.5/10
Disk space 6/10
E-mails, backups, etc: 8/10
Cost: 7/10
Ok...posting this here to hopefully get someone's attention at gnax.net.
I've written their abuse@gnax.net and engineer@gnax.net multiple times and even called into their support line and spoke with Stephen (or Steven). No one there seems to care.
They have a group of Vietnamese hackers on their network that are launching attacks from several of their servers. They also have a google phising site on one of the servers.
Spoke with Stephen at Gnax support and his answer was that it wasn't his job and I needed to send a e-mail to abuse. After telling him that I'd done that multiple times he basically said oh well that he didn't know what to do.
Seems like the admins of gnax.net are either very irresponsible, stupid or just ignorant.
Here are the URL's.

Just replace the 1's with t's and you can see for yourself. The fwooshnet.com attempts to download a trojan to your system so if you don't know what your doing don't visit either URL.

I just received a fairly scary WHMCS notice, you can view the details here:
<<please don't paste the file names, there are accounts that may have these on them>>
What are your thoughts on the entire situation? Personally, I'm a tad fearful (luckily, I hadn't upgraded to the next version yet as I was letting the other users play beta-testers) given the fact that there wasn't any versioning / modification 'notification' system in place on their end.
I'm fearing further updates. In essence, my concern is that the WHMCS development team isn't entirely certain how they were backdoored or to what scale they were backdoored.
Are their own billing systems & servers hosted in the same environment, were our billing details also released? etc. I want to know the scale of the attack.

I thought I knew enough about my .htaccess stuff to do this, but I can't seem to work it out. What I want to do is if a user visits domain.com/folder, we check to see if the folder exists. If so, show as normal (IE domain.com/support)
If a user visits domain.com/dynamicusername (dynamicusername is not a physical folder), redirect to dynamicusername.domain.com

how to set multiple databases for a single user in plesk.
It only alows 1 db per user.
I've been messing about a lot recently and I've had to rebuild my VPS template a lot in the past month. For some reason, Plesk is finding user data from a bunch of previous instances, so I've got to a point now where it's saying users exist when they can't be found in the panel interface.
I don't know how my VPS provider's infrastructure works but I'd presume that when I rebuild the server it's a total new instance and no data should carry over.
Is the the user data stored locally, and how would I go about clearing out the obsolete data?
