The below is a buried version of an infected folio.

Google SERP results produced by a pharma hack example:

Regenerating Spam Doorway – Examples

Shockingly in ane of the WordPress sites, a malicious wp-page.php was sighted which was creating auto-generated pharma spam doorways. On existence discovered, this file was immediately located and deleted. When we opened that wp-page.php in a browser to verify that the problem was resolved , malicious content was even so nowadays though it was non a buried page as per header information.

On a thorough examination, wp-page.php was nevertheless present with the current modification record. Information technology was discovered that this file tended to recreate itself even after getting deleted. Such a tendency resonates with malware using cronjobs to reinfect sites. Surprisingly, the user's crontab data did not evidence any signs of suspicious cron jobs.

Still farther scan of server revealed presence of malicious nav.php file which was responsible for creating wp-page.php file and also injecting malicious wp-page.php links into clean site pages when fetched past Googlebot or Bingbot.

...$movedb = user_min_browser($_SERVER['HTTP_USER_AGENT']);$movedb2 = 'moved';if ($movedb == $movedb2){ repeat '<ul>';echo '<li><a href="http://'.$mydomain.'/wp-page.php?t='.$myrandom_id_1.'">http://'.$mydomain.'/wp-folio.php?t='.$myrandom_id_1.'</a></li>';echo '<li><a href="http://'.$mydomain.'/wp-folio.php?t='.$myrandom_id_2.'">http://'.$mydomain.'/wp-page.php?t='.$myrandom_id_2.'</a></li>';...repeat '<li><a href="http://'.$mydomain.'/wp-folio.php?t='.$myrandom_id_20.'">http://'.$mydomain.'/wp-page.php?t='.$myrandom_id_20.'</a></li>';echo '</ul>';}

Now, the moot question was to find out how did nav.php file gets launched since it was not office of the theme. This inclusion of file was also done in the header.php of the aforementioned theme.

With a malicious code, the hacker provided reference to nav.php file in the header.php so that the malicious lawmaking executes immediately a public site folio loaded.

Quick scan for nav.php revealed this code in the header.php of the theme :

<?php include 'nav.php'; ?>

The coding was washed to facilitate the injection of spam to search engine crawlers and as well to recreate the wp-folio.php every time a public site page is loaded. This strategy was used every bit "delete protection" of the wp-page.php file.

The crux of the instance is that the website does not get secured just past casual scanning and removing malicious content, an in-depth scan has to exist done to ensure that the site is bug-free. This besides has to be ensured that the site is continuously monitored to gear up any cron jobs, backdoors, security holes, etc. which will help the website owner to proceed at bay from present and futurity hacker and their harmful strategies.

Appending wp-folio.php to legitimate requests isn't the real problem;  the actual problem is the regeneration of the file. For those unfamiliar with how themes work, if whatever include is added in the header file, it keeps loading the wp-folio.php file every time the theme volition be loaded past the visitors.

⭐ How does Pharma hack works?

Basically, the hack consists of ii parts—malicious files in the WordPress plugins folder coupled with encrypted code in the WordPress database. The files in the plugins folder comprise code that runs the encrypted lawmaking stored in the database. Because of this, the pharma hack is dependent upon these rogue files in the plugins folder.

Typically, hack files comprise easily-identifiable PHP functions like eval() and base64_decode(), and although the pharma hack is no exception, there's i major difference. With the pharma hack, these functions are stored in the WordPress database equally strings, and they're encoded backwards! At runtime, a hack file in the plugins folder pulls these strings from the database, flips 'em, and then runs 'em every bit functions, and that'due south how the deed gets done.

Generally, attackers chase for vulnerable WordPress installations i.due east sites using an old version of WordPress, vulnerable plugins, and themes, security loopholes or hosting multiple websites on the aforementioned account using free wordpress scanners. This leads to the very first pace to inject the backdoors into a compromised site.

When the backdoor is added, it is not immediately executed. Sometimes it stays for months without even getting called. The common places for these backdoors are:

wp-content/uploads/.*php (random PHP name file)  wp-includes/images/smilies/icon_smile_old.php.forty  wp-includes/wp-db-class.php  wp-includes/images/wp-img.php

Yet,  it is still calling eval(base64_decode simply it is using variables that makes it hard to discover. In fact, none of the WordPress security plugins are able to discover information technology. Therefore, await for such a string in your WordPress folders:

          php $[a-zA-Z]*='as';                  

If you do an inspection of the code, yous will come across that information technology scans for the wp-config.php file and gets the database information.

akismet/wp-akismet.php  akismet/db-akismet.php  wp-pagenavi/db-pagenavi.php  wp-pagenavi/class-pagenavi.php  podpress/ext-podpess.php  tweetmeme/ext-tweetmeme.php  excerpt-editor/db-editor.php  akismet/.akismet.cache.php  akismet/.akismet.bak.php  tweetmeme/.tweetmem.old.php
