For one thing, not having to worry about someone hacking your website and destroying years of work is a priority \u2013 but also, any user\u2019s data breach will undermine your audience\u2019s confidence and it\u2019s questionable whether they\u2019ll ever return. Even though website security is an on-going process, there are a few most common back doors for hackers that you can effectively avoid. That&#8217;s why we turned to well-known&nbsp; WordPress&nbsp; experts on the subject and organized a <a rel=\"noopener\" aria-label=\" (opens in a new tab)\" href=\"https:\/\/twitter.com\/search?q=%23WPSecurityChat&amp;src=typed_query\" target=\"_blank\">#WPSecurityChat<\/a> on Twitter along with the creator of 11+ million websites-powering plugin Yoast (<a rel=\"noopener\" aria-label=\" (opens in a new tab)\" href=\"https:\/\/twitter.com\/yoast\" target=\"_blank\">@Yoast<\/a>), the full-stack developer and marketing technologist Jono Alderson (<a rel=\"noopener\" aria-label=\" (opens in a new tab)\" href=\"https:\/\/twitter.com\/jonoalderson\" target=\"_blank\">@jonoalderson<\/a>), the PHP community force Cal Evans (<a rel=\"noopener\" aria-label=\" (opens in a new tab)\" href=\"https:\/\/twitter.com\/CalEvans\" target=\"_blank\">@calevans<\/a>), and SiteGround\u2019s WordPress Initiative Manager Hristo Pandjarov (<a rel=\"noopener\" aria-label=\" (opens in a new tab)\" href=\"https:\/\/twitter.com\/pandjarov\" target=\"_blank\">@pandjarov<\/a>). Here\u2019s a summary of their discussion with useful tips on how to safeguard your website against hackers. <\/p>\n\n\n\n<h2 id=\"h-top-5-common-ways-for-wordpress-sites-to-be-hacked-in-2021\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"top-5-common-ways-for-wordpress-sites-to-be-hacked-in-2021\"><\/span>Top 5 common ways for WordPress sites to be hacked in 2021<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress is a safe and secure software in and of itself. The majority of vulnerabilities are caused by the use of unreliable plugins, outdated themes and weak passwords. Hristo Pandjarov, our WordPress Initiatives Manager and SEO strategist outlines five most common backdoors: \u201cMy top five NOT ranked by priority, since any of those can cause enough harm are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Weak passwords<\/li>\n\n\n\n<li>Old plugins &amp; themes not updated<\/li>\n\n\n\n<li>XSS attacks&nbsp;<\/li>\n\n\n\n<li>Malware on computers with access to your site<\/li>\n\n\n\n<li>Weak passwords \ud83d\ude42 \u201c<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1480\" height=\"740\" src=\"https:\/\/academy.siteground.com\/en\/wp-content\/uploads\/sites\/2\/2021\/07\/Backdoors_for_Hackers_Hristo-1-1.jpg\" alt=\"Hristo Pandjarov on top 5 common ways for WordPress sites to be hacked\" class=\"wp-image-14812\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Using a password manager, such as LastPass or 1Password, is advised by our WordPress security experts. Over the years, having a very strong master password and then randomly-generated ones for different logins has proven to be the best solution. You can find more useful tips and simple steps that address the issues above in our blog article &#8220;<a href=\"https:\/\/academy.siteground.com\/en\/wordpress-security\/\n\" data-type=\"post\" data-id=\"13884\">5 Simple Steps to Secure your WordPress<\/a>&#8221; by one of the other participants in our #WPSecurityChat, Cal Evans.<\/p>\n\n\n\n<h2 id=\"h-most-hackers-don-t-care-about-your-site-s-popularity-according-to-our-security-experts\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"most-hackers-dont-care-about-your-sites-popularity-according-to-our-security-experts\"><\/span>Most hackers don\u2019t care about your site\u2019s popularity according to our security experts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Many website owners think that if your website is not hugely popular, then there is no reason for it to be a target. All of our WordPress experts agreed that it makes no difference whether your website is popular or not; everyone is at risk, and everyone should take measures to prevent hackers from gaining unauthorized access to their sites.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to Jono Alderson (<a rel=\"noopener\" aria-label=\" (opens in a new tab)\" href=\"https:\/\/twitter.com\/jonoalderson\" target=\"_blank\">@jonoalderson<\/a>), a Special Ops at Yoast, \u201cIt\u2019s much more common for attackers to try to compromise lots of websites at scale, via automated attacks. If they can take control of your site, they can inject links (for nefarious SEO purposes), redirect your visitors, or abuse your site\u2019s resources.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1480\" height=\"740\" src=\"https:\/\/academy.siteground.com\/en\/wp-content\/uploads\/sites\/2\/2021\/07\/Backdoors_for_Hackers_Jono-2-2.jpg\" alt=\"Jono Alderson on hackers compromising lots of websites at scale\" class=\"wp-image-14813\" \/><\/figure>\n\n\n\n<h2 id=\"h-how-does-site-security-affect-seo\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-does-site-security-affect-seo\"><\/span>How does site security affect SEO? <span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Jono Alderson, an expert at Yoast, the widely-used WordPress SEO plugin, summarizes that \u201c&#8230;so much of SEO is all about building up and demonstrating trust, relevance, and authority. If your site gets hit, there&#8217;s a real risk that all of that gets compromised.\u201d Your website\u2019s reputation and SEO are closely connected. For example, if your website displays irrelevant content to users and search engines, your relevance and trustworthiness will suffer.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1480\" height=\"740\" src=\"https:\/\/academy.siteground.com\/en\/wp-content\/uploads\/sites\/2\/2021\/07\/Backdoors_for_Hackers_Jono-3-1.jpg\" alt=\"Jono Alderson on website security and SEO\" class=\"wp-image-14815\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Because site security is so important, Jono Alderson also revealed helpful methods for determining whether or not your site has been hacked, \u201cMost good security plugins will also let you know when sensitive files have been changed or added, or when unusual behaviour has been detected. Make sure that you\u2019ve configured that kind of logging, and regular scans.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At SiteGround, we offer <a href=\"https:\/\/www.youtube.com\/watch?v=7bFxKceDyJ4\" target=\"_blank\" rel=\"noopener\" aria-label=\" (opens in a new tab)\"> SiteScanner malware detection and monitoring service<\/a>. The scanner lets you perform on-demand scans of your website as well as comprehensive daily scans to detect domain blacklisting and malware. <\/p>\n\n\n\n<h2 id=\"h-site-security-is-something-you-have-to-constantly-work-on\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"site-security-is-something-you-have-to-constantly-work-on\"><\/span>Site security is something you have to constantly work on<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is a common notion among our WordPress experts that webmasters tend to neglect site security over other tasks. Common mistakes include failing to update software, plugins, themes, and so on. Cal Evans, PHP developer and WordPress expert, shared his tips for avoiding common hacks \u201cBe diligent in maintaining your site. Check in daily to see what has changed. It&#8217;s ok for YOU to update plugins instead of waiting for autoupdate,\u201d adding \u201cKeep good backups and keep them for a while.\u201d&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1480\" height=\"740\" src=\"https:\/\/academy.siteground.com\/en\/wp-content\/uploads\/sites\/2\/2021\/07\/Backdoors_for_Hackers_Call-4-1.jpg\" alt=\"Cal Evans on maintaining your site security\" class=\"wp-image-14816\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">At SiteGround we try to take some of that load off your shoulders by automating many of these tasks as part of our managed WordPress security services. We automatically update your instances and their plugins to the latest version and patch against common WordPress-related exploits through our server firewall. Our latest <a href=\"https:\/\/newblog.siteground.com\/en\/geographically-distributed-backups\/\" data-type=\"post\" data-id=\"14457\" target=\"_blank\" rel=\"noopener\">backup service updates<\/a> include distributed physical backup locations and enhanced data protection which help enormously in event of a hacking incident.<\/p>\n\n\n\n<h2 id=\"h-how-can-your-web-host-help-in-keeping-sites-secure\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-can-your-web-host-help-in-keeping-sites-secure\"><\/span>How can your web host help in keeping sites secure?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If your website does get hacked, our experts suggest you contact your hosting provider&#8217;s <a href=\"https:\/\/www.siteground.com\/support\">support team<\/a> or a specialist. Hristo Pandjarov puts emphasis on \u201cRegenerating the <a aria-label=\" (opens in a new tab)\" href=\"https:\/\/twitter.com\/hashtag\/wordpress?src=hashtag_click\" target=\"_blank\" rel=\"noopener\">#wordpress<\/a> salts, to make sure there aren&#8217;t any logged hackers, plugin &amp; theme updates, malware scan of all computers with administrative access to your site and last but not least changing your hosting account pass and enabling 2FA auth!\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To add to the importance of choosing the right web host to help keep your website secure, Jono shares that \u201cGood <a href=\"https:\/\/www.siteground.com\/wordpress-hosting.htm\" data-type=\"URL\" data-id=\"https:\/\/www.siteground.com\/wordpress-hosting.htm\">WordPress hosting<\/a> companies also know WordPress inside-out. They\u2019ll make sure that your setup &#8211; and theirs &#8211; is hardened. They\u2019ll recognize and protect against common attack patterns, and know exactly what to do if things go wrong.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1480\" height=\"740\" src=\"https:\/\/academy.siteground.com\/en\/wp-content\/uploads\/sites\/2\/2021\/07\/Backdoors_for_Hackers_Jono-5-1.jpg\" alt=\"Jono Alderson on good WordPress hosting companies\" class=\"wp-image-14817\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">SiteGround is well-known for our powerful, yet simple to use managed WordPress services.
