I have recently brought a VPS hosting package. At the moment I am going through the tutoritals on the net that I have researched before getting a VPS package to give me some understanding on what I need to do to securior the server and also how to install the software that I require.
For most of today, I have been trying to sort out a problem that I am currently having.
Of which is I am trying to sort out a part of the tutorial from a website that requires the use of apt commands.
But for every command I am getting the message back apt..... Command not found. I am currently using the ubuntu operating system. And through some research, I have got the feeling that I might have the bare installation done on my server to just make it work.
Would I be right, and with the bare installation apt commands wouldn't be installed?
If I am, how would I go about installing the Apt commands and anything else that I might require?
root@server [~]# /etc/init.d/ipaliases start /etc/init.d/ipaliases: line 37: cat: command not found Not sure why that's happening, but 4 of 5 IPs are down and I cannot restart the network. Centos 4 / Cpanel The file is there in /etc/init.d/ -rwxr-xr-x 1 root root 2.6K Sep 26 21:54 ipaliases* Line 37 is case "$1" in
Is there a command i can type into the ssh console to stop a current transfer that i started wit the wget command?
the file im wgeting always stuffs up at 51% but then the server just retries and starts again, its done it 3 times so far and i just want to completely cancle the process if possible....
We were tasked with helping a website owner find all the malscripts on his site and remove them. He, like many, learned that his site was delivering malicious code with an email from Google.
This website owner had tried removing the code himself and yet his site was still blacklisted by Google. This was killing his sales as anyone visiting with Firefox as their browser, or Chrome, were greeted with a big warning:
This site may harm your computer.
After about a week of trying to rectify the problem himself, he contacted us.
He provided us FTP access to his site so we could tackle it.
After downloading his site (which literally took 3 hours) we started scanning. We grep'd for the word "base64_decode" and found over 228 php files all with the following malscript (spaces added to protect the innocent):
For the first time after running a server for about a year I decided to buy a new server and in it I found out that there is a some sort of infection in it. What should I do next. The logs are attached in a n attachment.
I cant visit my website! <snipped> everytime I go it says server not found. So I told some friends to go and they are able to see and visit <snipped> How is that possible?? They could and I cant? Yesterday same thing but then couple hours later it worked I could visit hmlegends.com but i didnt do anything and now today same thing server not found! i cleaned my history everything and still server not found!
So what I did is used a proxy <snipped> and then it worked!
But then I dont use a proxy SERVER NOT FOUND! Its like my IP cant reach hmlegends.com
I dont know how to solve this?!?? It just says server not found!
But it looks like everyone else could access it!
Anyways im using Firefox 2 but then maybe i thought it was my browser so switched to 3 so currently on firefox 3 and no its not its something with my IP cuz when i use proxy i could go to my site
but point is i dont wanna use proxy i wanna use my IP to go to hmlegends.com

And the error logs say..
[Sun Jan 20 18:09:56 2008] [error] [client xx.xx.xx.xx] File does not exist: /home/goewowc/public_html/404.shtml [Sun Jan 20 18:09:56 2008] [error] [client xx.xx.xx.xx] script not found or unable to stat: /usr/local/apache/cgi-bin/first.txt
The CGI-bin directory is chmodded correctly, the files are also chmodded and belong to the correct group
After going back and forth with the folks that are supposed to be managing my server they finally checked and found an irc bot. Here is their message:
I have found a irc bot running on your server. The binaries are located at /var/lib/texmf/.dat/. You can see the tar file which the hacker uploaded at /var/lib/texmf/. I have changed the permissions to 000 so that you can verify the files.
The user of the files are nobody. Hence it is clear that the files were uploaded via url injection using some vulnerable script under some domain. Unfortunately there are no helpful logs to find the exact domains and the vulnerable script. It is certain that the files were first uploaded to /tmp and then moved from there. You can see some similar hack files at /tmp/.dat, /tmp/var and /tmp/.dev12. Also the permission of /var/lib/texmf/ was 777.
You should update all your web softwares to latest version so that they will include latest security patches. Also I will recommend you to enable mod_security in your server to prevent further hacks.
Our Security Technician found yesterday a 200 user botnet on a hidden IRC server and was able to quickly email the compromised systems information (just hostname) to our abuse email. So today i spent the last 2 hours sending emails off to web hosting companies, educational institutions and corporate companies telling them that their systems have been compromised, we regulary email out systems we have found compromised. The thing that stuns me is that most of the systems we found compromised on IRC are dedicated lines between 10MBPS to 1GBPS... I found a few hosting companies and will list them so they can be found by them:

I just found a script on a customers account after some problems they were having, they mentioned injecting php code, that immediately threw up a red flag, when i took a look i found c99.php
I checked up and this seems to be the web equivalent of a rootkit.
Are there any legitimate reasons for this script? The customer is one of the strangest i've came accross because he had the lowest fraud score yet, used a Lady's name at signup/payment, yet calls himself Michael and seemed to do something with WHMcs security wise.. i dont want to post details as checks are still ongoing but it seems to be a problem with Language scripts and the customer was able to sign up on a monthly plan but Biannually... so no more invoices till 2009 ... strange, although wether innocently this was done or is a known security hole in WHMCS is not known yet.
after a day of crappy performance from one of my VPS accounts, I decided to start digging, and found eggdrop, and couple of other not so nice files in my /tmp directory.
I panicked, of course, and removed all traces of anything I could find that was bad, so I've unfortunately got no way to see how it happened, as far as I know (but I'm far from a security expert)
I need your help in shutting the system down to users. This is an HTTP/SSH/SMTP/POP3/IMAP server.
Tell me what you need to know and I will do my best to get it to you. Basically I'm just frustrated that I've been on it for 3 hours now.....wasting time because some SOB was bored....
I'll try to make this long story short, but this morning I logged into one of my servers and it showed a read-only filesystem, which I thought my server guys could fix easily. So I put in a ticket. 6 hours later, they tell me that they think the OS is corrupted and I need a new install. They give me KVM over IP so I can go in and 'do' things. I tried to log in as root and it wouldn't let me, so they finally booted in single mode and I can get in and such. When I try to su - root, it tells me that user root can't be found. I also tried to ftp into and out of the server with no luck. I really need this box back up. If not, I need to get all the accounts saved off so that I can build a new box. Everything is there, so I don't want to give up yet.
When I was a customer at hostgator, whenever a terminating error within php was displayed it would log in the parent directory in a file called "error_log".
I want this to happen now on our dedicated server. I've looked at my local apache error log and it doesn't appear to show the same info as hostgator's setup showed.
