What is a pharma hack?
Pharma hack, also known as Google Viagra hack, is a type of SEO spam attack, where a legitimate website is used to sell illicit drugs.

How to detect WordPress Pharma Hack?
Chances are, you found an issue with your website, and a little bit of Googling got you looking for pharma hacks.
Often with such hacks, when you visit the website directly, everything will be normal. It’s highly likely that one of your customers pointed out that your site has some weird pop-ups that redirect to illegal drugs for no reason at all.
Another reason to be suspicious is if you see your site ranking for very weird keywords that have absolutely nothing to do with your industry. If that
Here are some good ways to check if you are indeed a victim of a pharma hack:
- Google for your website + terms of banned drugs such as viagra or cialis
- Google for your website and visit your own site. If you get redirected to another site, you are infected by redirect hack, a form of WordPress pharma hack
- Sometimes these will only show up when you visit from a phone
- Inside Google Search Console
- Use fetch as Google
- Use a malware scanner
Of all these methods, using a malware scanner is by far the most practical and effective. We highly recommend that you do a server-level scan of your website for hidden malware.
But not all malware scanners are built equal. It’s quite likely that you already have a malware scanner installed on your website and the pharma hack still went undetected.
The reason behind this is quite simple – most malware scanners aren’t equipped to find malicious code. Instead, they look up signatures of popular malware on their database. A slight change in the malicious code can cause the malware to go completely undetected.
So, what can you do?
Sign up for MalCare. MalCare operates on an AI that grows smarter from each hack it encounters. This means that MalCare sniffs out malicious code even if it’s completely unknown and then it prevents that hack across 250,000+ websites that it protects.
How to fix a pharma hack?
There are 2 ways to fix WordPress Viagra hack:
1. Using a plugin (the easy way)
2. Scanning manually (the hard way)
Plugins are designed to make your life easier. But you’re welcome to try the hard way, if you like.
1) Scan and clean conditional pharma hack using a plugin
We recommend using MalCare to remove malware from your website.
The first scan takes a few minutes. The plugin is equipped with deep scanning technology which looks into every nook and corner of your website to find hidden and complex malware.
Just sign up and MalCare will start scanning your website for malicious files instantly.
Next, you will need to clean your website.
Removing malware with MalCare is the easiest way of cleaning a website. All you need to do is click a button – Autoclean.
And that’s it. Your site will be malware-free in under 60 seconds.
Go on, try Autoclean. You can do so much more with the time and energy you save.
2) Scan and clean Google Viagra hack manually
Unlike a plugin, manual scanning is neither straightforward nor quick.
Even if you are a skilled developer, comfortable with the idea of rummaging around WordPress files and folders, it takes a long time to find pharma hacks. Unless you are willing to spend days, if not weeks, minutely examining each line of code on your website, avoid scanning manually.
Whichever route you choose, remember to backup your website. Do not skip this step. No matter how skilled you are, WordPress websites are prone to crashing if you make a single mistake. For instance, installing an incorrect plugin version can cause your website to go into cardiac arrest. And it is just as much fun to experience.
To find WordPress pharma hack, follow the steps below:
Step 1: Download .php files
Pharma hacks are commonly found in .php files like:
Here’s how to download them:
- Open your web host account and go to cPanel > File Manager > public_html > index.php. Right-click on the file and select Download.
- Go to cPanel > File Manager > public_html > Themes. Open the theme which is active on your site. Right-click on header.php and select the Download option.
- Find the footer.php file in the same folder. Right-click and Download.
Step 2: Download the original copy of the .php files
The index.php file is part of the WordPress core files. You can get a copy from here. Just ensure that it’s the same version that is installed on your website.
The footer.php and header.php files are part of your WordPress theme.
If you have a free WordPress theme installed. You can download a copy from wordpress.org.
Paid theme users need to get a copy of their theme from the same marketplace where they purchased the theme.
Step 3: Run a Diffchecker
Next, open this URL, then upload both versions of each file manually to and run the diff check.
If you find scripts that are not part of the original files, they are probably part of the hack. But we don’t recommend removing any code unless you’re absolutely sure that it’s malicious.
In many cases, there are different versions of the WordPress core files for different languages. In other instances, free and pro versions of a plugin or a theme can have the same folder structure, but with vastly different code.
Some common functions found in malicious scripts are:
The functions are not malicious by default. Many plugins use them for legitimate reasons. Moreover, the checker will take a while to produce the differences and the results are not always 100% correct.
Please be aware that diff checker is not a replacement for a malware scanner. What you are looking to do is identify hack scripts, through the process of elimination. It is certainly not the most efficient nor accurate means to do so, and comes with its share of associated risks.
So, if you remove snippets of codes based on the results of the diff checker, you could end up wrecking your website.
That said, if you’re extremely confident about the code being malicious, removing these snippets should remove the malware from your site.
A manual scan is not a reliable way of cleaning a hacked website. We recommend installing MalCare which will get the job done within minutes.
With that we have come to the end of WordPress pharma hack fix. But before you move on, we highly recommend that you look at the next section.
WordPress pharma hacks are often caused due to vulnerabilities in plugins and themes. If you don’t remove them, the hack will return for sure. Here’s what you need to do:
- Update your plugins and themes immediately
- Remove all nulled plugins and themes installed, even inactive ones
- Delete inactive plugins and themes even if they are not nulled
Hackers tend to create rogue admins accounts to access your website after you have cleaned it. Find rogue admin accounts on your website and delete them.
These are only a few small security measures. For more comprehensive and enduring measures, we recommend reading our article on WordPress hardening.

Why are pharma hacks difficult to detect?
WordPress Viagra hacks are difficult to detect because of the following reasons:
1. Hackers target high-ranking pages because they receive a lot of traffic. Or they target pages with high earning potential. The hack won’t be present across the entire website making it hard to detect especially if it’s a large website with dozens of posts and pages.
2. This type of hack is not visible to you, the website owner. Nor is it visible to direct visitors. It’s only visible to search engines like Google or Bing. Hackers are targeting organic visitors who are looking for pharmaceutical drugs like Viagra, Cialis, and Levitra on the search engine.
3. Hackers want to utilize your website for as long as possible so they take steps to ensure that remains hidden. They have developed ways of disguising malicious codes which is difficult to detect even for seasoned programmers.
However, a good malware scanner can easily detect a pharma hack on your website ad help you clean it.
