How many WordPress sites get hacked?
No one knows exactly how many WordPress sites are hacked, but we estimate at least 13,000 per day. That's about 9 per minute, 390,000 per month, and 4.7 million per year. We come to this estimate based on the fact that Sophos reports that more than 30,000 sites are hacked every day, and that 43% of all sites are built on WordPress.
What percentage of WordPress sites are hacked?
According to Sucuri , 4.3% of WordPress sites that were checked by SiteCheck (a popular site security scanner ) in 2021 were hacked (infected). That's about 1 in every 25 sites. While not every WordPress site will use SiteCheck, it's still likely a good indicator of the percentage of overall WordPress sites that are hacked. Sucuri also found that 10.4% of WordPress sites are at risk of being hacked because they have outdated software .
Which CMS platform is most often hacked?
WordPress was the most frequently hacked CMS ( content management system ) in 2021, according to Sucuri's annual Hacked Websites Report. More than 95.6% of the infections detected by Sucuri were on WordPress-powered sites.
Top 5 Most Hacked CMS:
WordPress – 95.6%
Joomla — 2.03%
Drupal — 0.83%
Magento — 0.71%
OpenCart - 0.35%
It is worth noting, however, that the fact that most of the infections detected by Sucuri were found on WordPress-powered sites does not necessarily mean that there is any vulnerability in the core WordPress software . Instead, it is likely simply a reflection of the fact that WordPress is the most widely used CMS, and that WordPress users are more likely to use plugins like Sucuri than users of other CMSs.
What are the most common WordPress hacks?
Malware was the most common type of WordPress hack detected by Sucuri during incident response. A total of 61.65% of infections detected by Sucuri were classified as malware . Other common types of infections included backdoor hacks, SEO spam , hacking tools , and phishing hacks.

Malicious programs
Malware is the most common type of WordPress hack that Sucuri has found. It is a broad, all-encompassing term that refers to any type of malicious software used by cybercriminals to damage or exploit your WordPress site. The most common type of malware is PHP malware .
Malware is one of the most dangerous types of security infections because, unlike backdoors and SEO spam, it often exposes your site’s visitors to some kind of malicious activity. For example, one common example of malware is a SiteURL/HomeURL infection, which involves infecting your site with code that redirects visitors to malicious or fraudulent domains in order to steal their login information. Another example is credit card skimming: a web attack in which hackers inject malicious code into e-commerce websites in order to steal visitors’ credit and debit card information. Interestingly, statistics show that 34.5% of sites infected with credit card skimming are powered by WordPress.
