It is also a devastating feeling to find out that your web site is hacked. We have first-hand understanding with how expensive a compromise can be after spending years helping consumers scrub their compromised websites. Hackers also use the website to conduct malicious operations, such as redirecting visitors to their website, sending spam emails, adding backdoors, etc.
You could end up losing your search engine ranks, your customers ‘ interest, and your sales that way. Nevertheless, don’t think! All of this will only happen if you don’t scrub the website and fill in the void that originally caused the compromise.
We will take you through the process of cleaning a WordPress hack of CoinHive malware in this malware removal guide and take precautions to defend your website from such a hack attack in the future.
Then use our WordPress malware uninstall plugin if you want to get rid of CoinHive malware for good. Our automatic cleaner can automatically delete all malware from your site. That said, it’s not enough to clean your website, you will still have to protect it from potential hacking attempts. Therefore, to learn more about it, make sure you return and read the whole post.
What is CoinHive Malware?
CoinHive is a tool that helps website operators, by putting a code on their website, to earn sales.
The coding is intended to use the machine of your guest to produce income.
It is important to remember that cryptocurrency is the revenue in question, a type of digital currency that has been growing in popularity in the last few years.
Since more and more individuals are continuing to use ad blockers, CoinHive was rapidly embraced as an alternate revenue generator by site owners. The only issue was that hackers were still involved in the service because it made it easier for them to make quick money. Installing CoinHive codes on hack pages is everything coinhive miners have to do.
If you have identified the CoinHive code in your website header or footer, your visitors (or rather your visitors’ computer) will be used to produce digital currency.
The good news is that you can disinfect your website, i.e., delete and not take advantage of the CoinHive malware. You will also spare your guests a lot of headaches because their CPU is influenced by the mining process. It shortens their machines’ lifetime.
We’ll show you the exact steps you need to take in the next segment to clean up a WordPress ransomware hack for CoinHive.
How to Remove CoinHive Malware?
You will need to first clean the site and patch the flaw that triggered the hack in the first place in order to fully delete CoinHive malware from your website.
Step 1: Cleaning malware from your website with CoinHive
You first need to search it in order to uninstall CoinHive malware. The malware may be found manually or by using a protection plugin.
It is challenging to detect ransomware on your own. Back in those days, hackers had just a few places to conceal viruses because websites were not a complex network of files and folders. It was quick to manually find malware back then. No more, however. With hundreds and dozens of files and directories, websites today are complex. It was possible to conceal the CoinHive malware somewhere. It’s going to be a really time-consuming job to search through it manually, and on top of it, you can’t be sure that you’ll locate all the secret malware on the website.
Although if you want to use a protection plugin, it would make sure that your website detects all the viruses and in less time. That said, many security plugins suffer from limitations, which make it difficult to pick an efficient one.
Selecting the most appropriate Plugin for Defense
A protection plugin ‘s two key roles are to run a virus search and to clean compromised websites.
Most protection plugins do only a surface-level search when it comes to screening, i.e. they look only at areas where malware is normally located. The catch is, there could be malware buried somewhere. Therefore, to find all the CoinHive malware available on your website, a surface-level search is not enough.
In addition, several security plugins have been developed to search only for known malware. This ensures that even though you are using a protection extension, new forms of malware and especially complicated malware can go undetected.
But what if there is a plugin for encryption that is not afflicted by these weaknesses?
The MalCare Protection Plugin will fully search and disinfect your website as well.
- All Secret Malware Finds: MalCare reaches beyond the known area where malware is normally found. To detect secret malware, it searches at every nook and corner of your website.
- Finds new and complicated malware: It also goes one step forward and tests the sequence and actions of codes when the plugin searches for existing malware. Some codes are cloaked on the surface to appear clean, but they are harmful. Inspecting the codes requires modern and sophisticated malware to be detected by the plugin.
- Enable users to clean the site instantly: MalCare can clean the website after finding malware. For other protection plugins, it may take up to a few days to complete the cleaning process. It just takes a few minutes for MalCare, though. To start the clean-up process, all you need to do is press a button. That way, before Google can blacklist your domain or your web host can suspend your site, your website will be safe.
Now that you have a protection plugin that comes with a strong scanner and cleaner for WordPress ransomware, let’s try cleaning a website with it.
With MalCare, CoinHive Malware Elimination
1. On your compromised WordPress account, instal the WordPress protection plugin.
2. Add your site to the dashboard of MalCare and your website will automatically begin scanning. The plugin will tell you how many malicious files it has detected (as seen in the picture below) after searching.
3. You’ll need to clean it up now that the CoinHive ransomware has been discovered. To launch the cleanup process, just click on the Auto-Clean button.
It will take just a few minutes for MalCare to clean your place. It’ll alert you on the dashboard until finished.
You may think that you can heave a sigh of relief now with your site clean, but your site is far from being absolutely secure. We know hackers have obtained access to your website and compromised it with malware from CoinHive. But how in the first place did they obtain access to your website?
The hack cleanup is just half the fight. To fully restore your compromised website, you need to find and patch the vulnerabilities of your site.
Step 2: Correcting Weakness of Website
Generally, hackers obtain access to a website via vulnerabilities. Different ways of weakness exist. In your templates, plugins or even the WordPress heart, there may be glitches. Or it can be a rogue customer who gives access to the dashboard to hackers. You’d need to patch these bugs in order to close the hole that makes the hack. This is how you can do it—
i. Update your content with WordPress
Developing bugs is normal for apps. Themes, plugins, and key bugs evolve over time. Developers immediately issue a patch in the form of an upgrade to repair the programme as certain bugs are identified. When site owners do not change their themes, the vulnerabilities remain plugins and, heart, vulnerabilities. To hack your site, hackers take advantage of the vulnerabilities. Therefore, if you have installed obsolete applications on your site, upgrade it now. We firmly recommend that you keep your WordPress salts and security keys updated, in addition to having your extensions, themes, and core updated.
ii. Implement the principles of Least Privilege
You can delegate 6 different levels of tasks to a WordPress user ( i.e. someone who can log in and make site modifications). The highest degree is that of an administrator who has absolute power over your page. The admin position should be delegated only to persons you can trust. Having everybody an admin might be a nightmare formula. In exchange for a payment, a user will take advantage of the authority to encourage hackers to enter your site. A good one that comes to mind is when, using one of the blogger profiles, OurMine (a hacker group) hacked into TechCrunch.
iii. Using a secure password & special username
There is a login page on every WordPress website. It’s a key to your website, which is why hackers receive a lot of scrutiny. To initiate attacks on your login tab, they design bots. In order to reach your dashboard, the bots attempt to guess your username and password. Hackers can easily break into your website if you have an easy-to – guess username and password (such as admin and pssword123). Adjust your default username and create secure passwords for all user accounts (read the WordPress Login Safety Guide & prevention guide for brute force attacks as well).
There are some of the simple measures on your website that you should take to repair the vulnerabilities. The precautions you need to take to stop potential hack attempts on your site will come after this.
Preventing the WordPress Hack CoinHive
It’s hard enough to have the website compromised only once. It is going to be a tragedy to get compromised twice. The good news is that, by taking a few simple security precautions, you can save your site from being a target of another CoinHive WordPress hack. And those are the following:
I. Still update your website
We have spent hours researching hacked websites for close to a decade. And the only explanation for nearly all websites to stand out is obsolete tech. Keep your website, then, updated. To upgrade your website, set aside a few hours a week. Recommended reading: How can a WordPress website be updated safely?
II. Avoid pirated device use
Pirated themes and plugins are very enticing to use when they are cost-free, paid apps. Pirated tech, though, is also insecure. They often bring backdoors, a type of malware. The backdoors are enabled as you update the programme (i.e. plugin or theme) on your site and it helps hackers to obtain access to your website. So, delete them from your website right away if you are using pirated themes or plugins.
III. Stronger Certificates Incorporate
In the previous segment, we talked about this and we can’t emphasise this argument enough.
To reiterate: WordPress login pages are more often targeted on a WordPress website than any other page. Hackers tend to guess your website’s passwords in order to try to hack into your website. Using a distinctive username and solid passwords for this.
IV. Using a Plugin for Authentication
3 primary tasks are handled by a security plugin: screening, washing, and protection. It will help you to improve the protection of your website and detect whether your website has any suspicious activities. (We discussed earlier in the article how not all protection plugins function the same way and how a good security plugin can be chosen.)
With that, this segment on taking hack protection steps will be terminated. But not only does the list of steps that you should take to secure the websites stop here. To ensure your site stays secure, you can take several more measures. More on it in this protection tutorial for WordPress.
You should also take a few more security precautions in addition to these, such as changing your website from HTTP to HTTPS, shielding the login tab, and hardening the website for WordPress. In addition, we highly recommend Safe Your WordPress Platform With wp-config.php following this tutorial.
The hacking of CoinHive malware will create significant problems for a website owner and your number one priority should be to clean it up. The problem is that with the aid of the vulnerabilities present on your web, malware will return even after cleaning your site. In addition, there’s no guarantee that in the future the website will be safe.
Therefore, to delete the bugs and certain precautions to protect the websites from potential hack attempts, you need to take certain actions. A big move in that direction is to add a security plugin. It will help you repair weaknesses and shield your website from hackers and bots.
