WordPress is, by means of some distance, the most popular way to build a website. That recognition has the unlucky aspect impact of additionally making WordPress websites a juicy goal for malicious actors all the world over. And that may have you ever questioning whether or not WordPress is safe sufficient to deal with the ones assaults.
First – some dangerous information: Annually, masses of hundreds of WordPress websites get hacked.
Sounds grim, proper? Smartly…no longer actually, as a result of there’s additionally just right information:
Hackers aren’t getting into because of vulnerabilities in the most recent WordPress core instrument. Reasonably, maximum websites get hacked from solely preventable problems, like no longer holding issues up to date or the usage of insecure passwords.
In consequence, answering the query of “is WordPress safe?” calls for some nuance. To do this, we’re going to hide a couple of other angles:
- Statistics on how WordPress websites in truth get hacked, so you already know the place the safety vulnerabilities are.
- How the WordPress core staff addresses safety problems, so you already know who’s accountable and what they’re chargeable for securing.
- If WordPress is safe while you apply absolute best practices, so you already know in case your site shall be protected.
How WordPress Websites Get Hacked (By way of The Information)
Adequate, you already know that a number of WordPress websites are getting hacked every yr. However…how is it going down? Is it an international WordPress factor? Or does it come from the ones site owners’ movements?
Right here’s why maximum WordPress websites get hacked, in keeping with the knowledge that we have got…
Out-of-Date Core Tool
Right here’s an unsurprising correlation from Sucuri’s 2017 Hacked Website Report. Of the entire hacked WordPress websites Sucuri checked out, 39.3% have been operating out-of-date WordPress core instrument on the time of the incident.

So immediately, you’ll be able to see a horny shut dating between getting hacked and the usage of out-of-date instrument. Alternatively, that is unquestionably an development over 61% from 2016. 
In line with the WPScan Vulnerability Database, ~74% of the identified vulnerabilities they logged are within the WordPress core instrument. However right here’s the kicker – the variations with probably the most vulnerabilities are all long ago in WordPress 3.X:
WPScan listing of identified vulnerabilities
However – sadly – only 62% of WordPress sites are operating the most recent model, which is why many websites are nonetheless unnecessarily prone to the ones exploits:
WordPress Utilization By way of Model. (Symbol supply: WordPress.org)
In any case, you’ll be able to see this connection all over again with the major WordPress REST API vulnerability from February 2017 the place masses of hundreds of websites have been defaced.
WordPress 4.7.1 contained more than one vulnerabilities that have been sooner or later used to deface the ones websites. However…weeks prior to the vulnerabilities have been exploited, WordPress 4.7.2 was once launched to mend all of the ones vulnerabilities.
All of the WordPress website online house owners who hadn’t disabled automated safety patches or differently had promptly up to date to WordPress 4.7.2 have been protected. However those that didn’t observe the replace weren’t.
Takeaway: The WordPress Safety Group does a really perfect process at temporarily solving problems within the WordPress core instrument. In case you promptly observe all safety updates, it’s extremely not likely that your website online studies any problems because of core vulnerabilities. However if you happen to don’t, you are taking a possibility as soon as an exploit will get out into the wild.
2. Out-of-Date Plugins Or Topics
Some of the issues other folks love about WordPress is the dizzying array of available plugins and subject matters. As of penning this, there are over 56,000 at the WordPress repository, and hundreds of extra top rate ones scattered around the internet.
Whilst all the ones choices are nice for extending your website online, every extension is a brand new attainable gateway for a malicious actor. And whilst maximum WordPress builders do a just right process of following code requirements and patching any updates as they change into identified, there are nonetheless a couple of attainable problems:
- A plugin or theme has a vulnerability and, as a result of there aren’t as many eyes on it because the WordPress core instrument, that vulnerability is going undetected.
- The developer has stopped operating at the extension however individuals are nonetheless the usage of it.
- The developer temporarily patches the problem, however other folks simply don’t replace.
So how large is the problem?
Smartly, in a survey from Wordfence of hacked site house owners, over 60% of the site house owners who knew how the hacker were given in attributed it to a plugin or theme vulnerability.

In a similar fashion, in Sucuri’s 2016 document, simply 3 plugins accounted for over 15% of the hacked web sites they checked out.

Right here’s the kicker, regardless that:
The vulnerabilities in the ones plugins had lengthy since been patched – website online house owners simply hadn’t up to date the plugin to offer protection to their website online.
Takeaway: WordPress subject matters and plugins introduce a wildcard and can open your website online to malicious actors. A lot of this possibility may also be mitigated by means of following absolute best practices, regardless that. Stay your extensions up to date and best set up extensions from respected resources.
We even have to say those GPL golf equipment you could see floating across the web the place you’ll be able to get any top rate WordPress plugin or theme for only a couple greenbacks. Whilst WordPress is authorized underneath GPL, which is superior and one explanation why we like it, purchaser beware.
Purchasing plugins from GPL golf equipment imply you’re trusting a third-party to clutch the most recent updates from the developer and a large number of instances you received’t get fortify. Getting plugin updates from the developer is the most secure course. Additionally, we’re all about supporting builders and their arduous paintings!
3. Compromised Login Credentials For WordPress, FTP, or Webhosting
Adequate, this one isn’t actually WordPress’ fault. However a non-trivial share of hacks are from malicious actors getting their palms on WordPress login credentials, or the login credentials for site owners’ internet hosting or FTP accounts.
In that very same Wordfence survey, brute power assaults accounted for ~16% of hacked websites, with password robbery, workstation, phishing, and FTP accounts all creating a small, however noticeable, look.
As soon as a malicious actor will get the metaphorical key to the entrance door, it doesn’t subject how differently safe your WordPress website online is.
WordPress in truth does a really perfect process mitigating this by means of routinely producing safe passwords, but it surely’s nonetheless as much as customers to stay the ones passwords protected and in addition use sturdy passwords for internet hosting and FTP.
Takeaway: Taking fundamental steps to stay account credentials safe can save you malicious actors from strolling proper in. Use/put in force sturdy passwords for all WordPress accounts and restrict login makes an attempt to stop brute power assaults (Kinsta hosting does this by means of default 
).
For internet hosting accounts, use two-factor authentication if to be had and not retailer your FTP password in plaintext (like some FTP methods do).
When you have a call between FTP and SFTP (SSH Report Switch Protocol), at all times use SFTP. This guarantees that no transparent textual content passwords or report knowledge is ever transferred. We best fortify safe connections at Kinsta.
4. Provide Chain Assaults
Lately, there were some circumstances the place hackers acquire get right of entry to to websites via an uncongenial trick referred to as a provide chain assault. Necessarily, the malicious actor would:
- Acquire a up to now fine quality plugin indexed at WordPress.org
- Upload a backdoor into the plugin’s code
- Look forward to other folks to replace the plugin after which inject the backdoor
Wordfence has a deeper explanation if you happen to’re . Whilst most of these assaults are in no way well-liked, they’re tougher to stop as a result of they consequence from doing one thing you must be doing (holding a plugin up to date).
With that being mentioned, the WordPress.org staff typically temporarily spots those problems and eliminates the plugin from the listing.
Takeaway: This one may also be arduous to stop as it’s a just right factor to at all times replace to the most recent model. To assist, security plugins like Wordfence can warn you when a plugin is got rid of from WordPress.org in order that you temporarily cope with it. And a just right backup technique permit you to roll again with none everlasting injury.
5. Deficient Webhosting Surroundings And Out-Of-Date Generation
Past what’s going down for your WordPress website online, your internet hosting atmosphere and the applied sciences that you just use make a distinction, too. For instance, in spite of PHP 7 offering many security enhancements over PHP 5, best ~33% of WordPress websites are the usage of PHP 7 or upper.

PHP 5.6’s safety fortify formally expires at the end of 2018. And previous variations of PHP 5 haven’t had safety fortify for years.
That suggests the usage of a internet hosting atmosphere the usage of PHP 5.6 or beneath will quickly open you as much as the potential for unpatched PHP safety vulnerabilities.
Regardless of that truth, a whopping ~28% of WordPress web sites are nonetheless the usage of PHP variations underneath 5.6, which is a big factor while you imagine that not too long ago we’ve seen record years for the collection of came upon PHP vulnerabilities.
Past supplying you with get right of entry to to the most recent applied sciences, using secure WordPress hosting too can assist you to routinely mitigate lots of the different attainable safety vulnerabilities with:

Formally, that accountability falls to the WordPress Safety Group (regardless that particular person participants and builders from all over the world additionally play an enormous position in holding WordPress safe).
The WordPress Security Team is “50 professionals together with lead builders and safety researchers”. About part of those professionals paintings at Automattic. Others paintings in internet safety, and the staff additionally consults with safety researchers and internet hosting corporations.
In case you’re considering an in depth have a look at how the WordPress Safety Group purposes, you’ll be able to watch Aaron Campbell’s 48-minute talk from WordCamp Europe 2017. However basically, the WordPress Safety Group:
- Detects and patches insects and attainable problems the usage of, partially, gear like HackerOne’s bug bounties
- Consults on all WordPress core releases
The WordPress Safety Group has a coverage of disclosure this means that that, after they’ve effectively patched the worm and launched the safety repair, they publicly divulge the problem (this is a part of why such a lot of websites were defaced in 2017 – they nonetheless hadn’t implemented the replace even after the safety staff publicly disclosed the worm).
What the WordPress Safety Group does no longer do is take a look at the entire subject matters and plugins at WordPress.org. The subjects and plugins at WordPress.org are manually reviewed by means of volunteers. However that evaluation isn’t “a ensure that they’re unfastened from safety vulnerabilities”.
So – Is WordPress Safe If You Apply Highest Practices?
In case you have a look at the entire knowledge and info above, you’ll see this basic pattern:
Whilst no content management system is 100% safe, WordPress has a high quality safety equipment in position for the core instrument and many of the hacks are an instantaneous results of site owners no longer following basic security best practices.
In case you do such things as…
- Stay your core WordPress instrument, plugins, and subject matters updated.
