Sep 4, 2007All my sites on both my hosting accounts are infected with an iframe.
At the end of the index.html files the malicious code just appeared...suddenly 3 weeks ago.
The host blamed Joomla so I took the appropriate steps:
Upgraded my Joomla to the latest version, changed the whole account username and password, changed the configuration and template to unwriteable.
It stopped the injection for a few days but then it came back.
I would also like to add that 2 other sites on my account, one simple index.html file and an old website I have that is totally HTML with nothing to do with Joomla also got infected.
The iframe also infected a Drupal install I did as a test.
So according to these fact is this a Hosting Company not taking responsibility or can a Joomla site infected spread to other normal HTML sites and different CMS's on the server?
This situation is ruinning me and I strongly suspect it's a Hosting problem and not Joomla.
Any expert opinions from true professionals would be appreciated because if I can prove that it's not a Joomla issue I might take legal action against the hosting company since this has cost me dozens of hours of work and several hundred dollars of lost revenue.
I am attaching the iframe exploit. It installs itself on every index file...in every folder - components, mambots, ect..additionally it attaches itself on any and every kind of addon that has an index.html file.
DDoS Prevention .....
May 13, 2009I have searched for prevention methods and explanations on what DoS's and DDoS's are capable of. I was hoping someone could shed some light on free alternatives that would help reduce these attacks or help to make me aware if one were to occur.
Linux Distro: CentOS 5.3
I am not running apache or any web related services on my machine.
I run a dedicated server for the sole purpose of hosting a few game servers. I have already contacted my provider and they offered a $599 /mo plan for prevention. This is unreasonable and I simply cannot afford it. I have been threatened with a DDoS because one of my administrators banned a player constantly creating drama, stress, and breaking rules.
I simply cannot afford a gigantic bandwidth bill and this scare tactic has made me a little weary. Is there anything I can do to reduce the damage?
UDP D/DoS Attack - Best Prevention
Apr 27, 2008I would like to know what are the best ways in preventing a UDP D/DoS Attack. DDoS-Deflate and most programs like that are just for TCP connections, and most of the time only for port 80. What is the best option out there for protection (linux wise) for UDP attacks. I was using shorewall before but it did not do so well so I just switched now to CSF [url] with WebMin and seems to be working ok. Even though thoes are both firewalls, they seem to have some protection against UDP Attacks. Please note this is a server that just hosts some game servers, no webhosting. What would be my best option here?

DDOS Prevention Options
Mar 23, 2009My host has told me that my forum is coming under a DDOS attack. Once was on Friday March 20th and again today (monday march 23). Before those two, there are attacks almost every week, sometimes twice a week.
The host installed DoS-Deflate. It started blocking legitimate traffic and had to be removed.
The operating system is Linux CentOS, the forum software is VBulletin. The server is a VPS with 1 gig of memory.
Besides DoS-Deflate, what other options are out there?

AWStats Exploit Attempt Prevention

Hot Link Prevention And Browser Security
Dec 23, 2007I recently initiated "Hot Link Prevention" on one of my web sites on my Dedicated server (via CPanel). It woks well in re-directing hotlinked images to a small image that says "Unauthorized Hotlink Image." This of course prevents other web sites from leaching my bandwidth. However, I have had a number of people complain that when they visit my forum, they don't get my site's images, but instead see the Unauthorized Hotlink Image. The common thread seems to be the people with the problem are using Security Software. In one case, a guy is using Norton Confidential. Another guy is using some Security software provided by his ISP. I'm guessing that this security software is somehow messing with the Referer in tehir browser and confusing my server into thinking the images are being hotlinked from some other site. Short of turning off Hot Link Prevention, does anyone have any suggestions to tell the folks...are there settings in their Security Software for example that will prevent the problem when they visit my site?

Iframe Injection
Jul 22, 2009Yesterday it was discovered that a website had most or all of the html pages compromised with some sort of iframe injection. Every page had an iframe line added to the bottom that attempted to load something from another website. It was coming from a domain called reycross.net and was attempting to load the html/framer virus into the visitor's computer.
The problem is that I cannot identify how the injection hit the system. Here are the facts I can provide...
1. The server does NOT have Joomla or Wordpress.
2. The injection seemed to hit every html page whether the page was active on the site or not.
3. The injection hit only one account.
I have checked /var/log/messages and /var/log/secure and find nothing.
What I don't have is proper ftp logging to determine whether the injection came from that method.
Additional notes: Shortly before the injection took place the box was updated to the latest version of cpanel. Also php was upgraded to 5.2.10. At the time suPHP was enabled but unfortunately had to be disabled because it created problems with another site. Prior to this suPHP was disabled as well.
I went through and removed all instances of this iframe injection and ran another update of cpanel. I also recompiled apache/php and went back to 5.2.8 in case the problem was php related.
PhpMyAdmin SQL Injection
Dec 13, 2008Anyone using phpMyAdmin for MySQL admin, you need to know about a newly discovered attack vector.
Here's the official announcement: [url]
The key to this is in their description, "A logged-in user can be subject of SQL injection through cross site request forgery. Several scripts in phpMyAdmin are vulnerable and the attack can be made through table parameter."
A logged in user... This attack is a combination of SQL injection through CSRF. In other words, you'd have to be logged into your phpMyAdmin program, hit a website setup for CSRF, and then the attacker could have access to your phpMyAdmin as you.
If there's interest here, I could write up a detailed description of CSRF and how to prevent this type of attack.
Just let me know...
You should upgrade immediately to either phpMyAdmin 2.9.11.4 or 3.1.1.0 or apply patch 12100.

Php Injection & Session Hacking
May 28, 2008I had done a program in early 2006 for a site in php-mysql. At the time of doing the code, The code written was not so standard and it contained uninitialized variables used for include file paths (eventhough values are assigned to it before using) and the "sess" folder was created within the website folder. Also the parameters for the SQL query were not escaped, but everything was working fine.
And now i was informed that the insecure code in my program caused the server crash and i have to pay the penalty for the same. Can anyone let me know whether the below code / keeping the session variables within a folder inside the /www/ will make the sites hosted on the server where this program runs to stop/crash for ever ?
------------------------------------------------------------------
function update_region($id,$regname,$regcom)
{
$query = "UPDATE taxregion_mast SET taxregion_name = '". $regname."',
region_comments = '". $regcom."' WHERE region_id =" .$id;
