I have a client that is certain someone is trying to hack her web-portal. I need to set up something that will alert me on suspicious activity on the server. For example someone fiddling with requests trying to make SQL / shell .. injection and similar threats.
Does any tool (for example bash script with grep) exist that would parse the raw apache logs and report if something is suspicious. Apache logs don't show the POST data so I am talking to admin to setup dump_io apache mod that enables this.
Or am I going into wrong direction here and there is whole another way to do this? I searched the web and forums for anything like this and didn't find anything.
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.
When I looked at the accounts in Direct Admin some of them had the contact email to some hacker so i deleted the emails and changed password on the DA account and the email of those accounts.
Still I got too many files all the time so the server goes down so i have to delete the spoolfile all the time like 10 times a day
Please help how do I detect from what account do the hacker operate?
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?
we have been having a strange hacking problem on our server that we can not seem to find how they are managing to accompish. I am just wondering if anyone here may be able to offer any suggestions on this?
The problem:
On our server, a hacker has managed to add malicious code to all html and php files on two hosting accounts that we operate. These two accounts are seperate and do not share login information. This is the 2nd time this has happened within the past two weeks.
Originally it was suspected that we needed to add SuPhp to prevent insecure permissions. This has been done, yet the problem continues.
On all html pages, malicious javascript has been added, and on all php files malicious php code has been added.
We have a lot of accounts on this server, and as mentioned only the two accounts seem to have been affected by this.
What we have done to attempt to secure the server: 1) We have installed SuPhp.
2) We have ensured that all scripts on the affected websites are updated and running the latest versions.
3) We have changed all the passwords.
Our server is a managed server, and our server company has been very helpful, however at the moment can not seem to pinpoint the problem. There also does not appear to be any indication via the access logs of the infected files being altered, yet they have been altered.
The computers used to access these websites are clean, and do not have any malware running, which would allow a hacker to obtain any passwords. It also does not appear that the hacker was able to obtain root access.
One other thing I noticed, we run Kayako on one of the sites. When this problem occurs we receive a message that Zend Optimizer is not installed on our server when attempting to login to Kayako, when in fact it is.
Searching Google, I found the following link on the Zend site in which the symptoms seem to be very similar. What are the odds this could be a Zend vulnerabilty?
My Windows VPS has come under heavy attack by hackers trying to get through MSFTPSVC for the past month and they finally managed to somehow get in 2 days ago. Somehow, the "Allow anonymous login" setting was selected in my FTP settings and they got in.
They even managed to turn off my firewall. I guessing they used a buffer overflow or some other Windows Server 2003 weakness that was fixed in SP2 (too bad SP2 is'nt supported by SWSoft yet).
The attacks began less than 1 week after I had signed up with Virpus. I did'nt even have my domain name pointing to the server or a site up when the first set of dictionary attacks began. How common is that 0_0 ?
Anyway, since I now know they've gotten in I've run a virus check and everything looks clean but I really want to run some kind of root kit detection software. I've tried everything suggested on the antirootkit website but none of them seem to work on a VPS.
And im getting the following in an email every 10 minutes:
Code: /usr/local/bfd/conf.bfd: line 26: : command not found /usr/local/bfd/conf.bfd: line 38: : command not found /usr/local/bfd/conf.bfd: line 47: : command not found /usr/local/bfd/conf.bfd: line 59: : command not found /usr/local/bfd/conf.bfd: line 60: : command not found /usr/local/bfd/conf.bfd: line 76: : command not found /usr/local/bfd/conf.bfd: line 88: : command not found The email is being sent from:
Now i know this isnt r-fx networks support but none of there support options seem to work so i figured id post here considering the amount of users that are likely to be using bfd (or you should be)
I downloaded the tripwire version 2.4.1.1 but after the installation the /etc/tripwire/twinstall.sh file is not generated after the installation. I checked the contents of the RPM I downloaded and the script is not there.
How can I prepare the cfg file without this script?
Is there a tool for intrusion detection where a central machine is responsible for requesting clients for file and directory information and reporting changes?
Do you know of any open source package preferable are available for RHEL4 and 5?
For those who are still under the softlayer hacker abuse please note you will need to re-load your server. We got hit a 2nd time after thinking everything was clean. Anyhow, for those who got hit again, my team and another from WHT - forgot who made the original clean.php script...
anyhow, here is a tool to clean all the data for all of your users:Copy fixit.pl and clean4.php to a directory. IE: /home/yourusername
Change username "changeme" in fixit.pl to the username where clean4.php is located execute fixit.pl: IE: perl fixit.pl. If you want to test this on one user uncomment the die statement. When you are ready to do the entire server comment the die statement.
i've got a couple of vps accounts and one got hacked today, i received a domain creation email for a domain i didn't create, password was "hackedonlyhost" and contact was not my email but someone elses. Root password was changed etc etc, but i managed to get control of the vps again.
Why am i posting this in the ded forum? because the email in the account setup was for a hosting company. I traced the ip to LT. I've found this guy on a couple of hacker forums (arabic, he's in egypt) also using his email at his hosting company.
So, whilst he may not be breaking LT rules at all do i bother contacting them to say they are providing services to hacker?
There Is Some Way That Hacker use a .htaccess file to change the php Version On The Server To use the Exploit Look I Run A php Shell From My Server [url] You Can See From The picture that my php version is 5.2.6 then I Have upload the .htaccess To My server the Version has been changed look to other picture [url] You Can see The .htaccess file And This Way Only Work If I have More Than one php Version on my server How Can I Secure My server From This Way
I'm still trying to figure this one out. I got an email last night about 10:30pm that a weird IP had logged with root. I thought it was a guy that helps with tech things but I ran the IP... it came back from Korea and I knew I was in trouble. I immediately logged into WHM and changed the root password then sent the server down for a reboot. He was only in there for about 3 minutes before I nailed him. I've banned the IP from the server and have been watching it for nearly 12 hours now and they haven't came back yet.
Now comes the task of trying to figure out how he got the password. This is mind boggling to me. He knew the password, like someone gave it to him... there were no incorrect guesses or brute force. The password was a series of random letters, both upper and lower case. Is it possible he got it through getting to /etc/passwd via a PHP script? I have open basedir restrictions in place, can they get around that? I noticed at the time he logged in there were several IPs trying to exploit PHP scripts on my server, you know, setting the parameters to txt files but I assumed with shell functions disabled (except exec) and with open basedir this wouldn't be possible. Is there a hole in cpanel / PHP / kernel recently I may have missed?
As with many sites. my site was hacked recently. my host was so negative about this. they didn't notice the hack attempt although it took the hacker 9 hours to break through.
after that I made some search on my host to find that it is not a real host at all. they are just resellers to another company. I was very disappointed, Then I decided to go to a better host who can protect me from hackers.
I read some threads about 'hacker safe host' but they all in general don't give a real name of trusted 'anti-hackers' companies.
can you guide me to some of the famous hosts?
if you can't my friends got a VPS hosted with WestHost. he offered me to move my site to his VPS. is west host trusted about hackers?
I was checking my business server's IIS errors logs when I ran across the following error:
2007-05-19 08:21:10 00.000.000.00 2243 00.000.000.000 80 HTTP/1.1 GET
/w00tw00t.at.ISC.SANS.DFind 400 - Hostname -
Additional information about the those responsible for the hack attempts are as follows

Apparently this person was trying to use the dfind hacker tool to find vulnerabilities on my server. The IP address belongs to AT&T Yahoo; and I've already contacted them by email. I believe that subsequent hack attempts have originated from this IP, however, the IP address has been masked by the use of proxies. I think that this may be someone I know because the IP is only about an hours drive from me. I'm starting to suspect a disgruntled former client who has friends living where that IP's from.
Has anyone here had any similar experiences?
What do you think AT&T Yahoo's response will be?
Is there anything else I can do or should not do?
I am also considering reimaging my server because of system issues but I am concerned that would erase any information needed for investigative purposes. I have saved my log files, though, on a CD but I'm thinking that AT&T Yahoo or whoever investigates this needs the server as it is.
I want to ask about some tips to prevent my blog from hacker attack. My friends experience this and i dont want this happen to me. Is web hosting technical support can fix my host server if hacker break it out?
I'm having a problem with a hacker...using insecure scripts on my user's accounts he changes Cpanel passwords. I do not understand how a script running as user nobody would change a Cpanel password. Any ideas on that ?
I am using mod security (rules from gotroot.com), register_globals are disabled. I also disabled the password reset feature as I thought the hacker may be resetting the passwords and then reading the new password from the email account on the server using the insecure script.
Unfortunately this guy simply doesn't stop...he seems to have a reverse DNS list or something. He is only attacking accounts on one specific server of mine but I am pretty sure he doesn't have root access.
It seems like someone has hacked into my server, and all of the pages for one of my domains are showing errors.
Each page on my site is showing a PHP inclusion error, each file on my site is trying to include an unknown file /tmp/blah.php for example which doesn't exist on my site, therefore creating errors and not showing my site.
I checked my site in ftp, it isn't in the code. So it is definitely in a server file somewhere.
What could be doing this? Its for a single domain only, I've created the file it is trying to include as a temporary fix, I have checked php.ini and there seems no reference to the included file there.
I have two reseller accounts with Innohosting and a hacker has got into several sites on both accounts. I have contacted Innohosting and hopefully will get an explanation soon.
But as this is very serious, I want to put it out on this forum also.
At first I thought they must have cracked my FTP access, but they have got into several sites on both reseller accounts so they must have gained access to the server itself, I suspect.
my VPS hosted by Strato was hacked and seems to be part of a botnet now. Until now I thought that the automatic backups of the provider would be enough and I did no separate backups using pleskbackup. Unfortunately the hacker attack was earlier than my oldest backup.
Now I want to move the complete server content including the configuration of approx. 10 domains to a new one. Therefore I want to make a backup of the plesk 9.5 server using pleskbackup to import it on the new server running plesk 12.I can access the old server in recovery mode only, which means, that a recovery system runs with the content of the old server mounted under /repair. Is there a possibility to tell pleskbackup, that the content to backup is mounted under /repair? Otherwise it seems, that I have to move the content manually...(I tried starting the old server in normal mode, but it immediately starts doing evil things, so this doesn't seem a good option...)
to open EML files on apache webserver, actually when I load an eml (outlook email message) by using an URL, it shows the email code, it is not pasing it correctly.
What libraries (apache or system) do I need installed to parse this kind of files?
My server is with Centos OS. I have a cache directory which has tons of scrap files. I am unable to delete it. rm -rf dirname gives an error.Is there any way to remove this directory quickly.
how can i hide all files and directories in public_html so when using apps suck Flash Get Site Explorere and similar software it will not show any file or directories in public_html.
I have moved my sites from old server with Apache 1.3 to new one with Apache 2.2.4. Since that time, the error log is full of these lines:
Code: [Wed Jul 04 05:36:32 2007] [error] [client 212.47.9.194] File does not exist: /home/domain/public_html/russia [Wed Jul 04 05:36:39 2007] [error] [client 212.47.9.194] File does not exist: /home/domain/public_html/russia [Wed Jul 04 05:36:45 2007] [error] [client 213.192.18.2] File does not exist: /home/domain/public_html/italy [Wed Jul 04 05:36:57 2007] [error] [client 83.8.104.181] File does not exist: /home/domain/public_html/mexico The access logs show even more accesses, so sometimes the same page is ok, sometimes it is logged here. The strange thing is that these files (pages) exist! They are accessible through the browser without any problem.
Do you have any idea where could be the problem? It would helped me lot, I am unable to find any real problem now, when error log is full of these.
My OS is Ubuntu 6.06. I use mod_rewrite through .htaccess. I can provide list of apache modules, if it helps.
I noticed that all sites on the server, can not parse php files, tried restarting httpd, recompiling using apache update or easyapache script, and the problem stills.
index.php is at DirectoryIndex, also Addtype shows php extension active at httpd.conf.
but, when I type "php -v" from the shell, i got this message:
Code: php: /usr/lib/libmysqlclient.so.14: version `libmysqlclient_14' not found (required by php)
I found someone with the same problem, tested the solution posted there but it doesnt seems to solve this issue.
I'm moving to a dedicated server for first time in my life and I have some questions that I want to share with you all.
I have run many scripts like joomla, vbulletin, etc, and I have found that when I install a module or template or when I upload images using this scripts, the permisions of this files are wrongly assigned as they belong to apache:apache instead of myuser:mygroup.
The problem is that as my new server is going to be fully managed, I am not going to have root access to chmod this files to the right myuser:mygroup and as a consecuence I'm going to be unable to dmove or delete them usinf my ftp or shh user acount.
Hope you can help me this this issue. I need to tell my hosting company what I want to do to avoid this way of working but I have no idea of how can this be solved
