Why Unpatched WordPress Sites Are a Hacker's Favourite Target (And Why Your MSP Should Manage It)
WordPress: The Double-Edged Sword of the Web
WordPress powers more than 40% of all websites globally. For Australian small and medium businesses, it is often the default choice for company websites, blogs, online stores, and client portals. It is flexible, affordable, and has an enormous ecosystem of plugins and themes.
That popularity comes with a cost. WordPress is also the most targeted content management system on the internet by a significant margin.

Why Attackers Love WordPress
The Numbers Tell the Story
- WordPress sites account for over 90% of all hacked CMS platforms according to security industry reports
- In 2025 alone, over 4,700 new vulnerabilities were disclosed in WordPress core, plugins, and themes
- 56% of all WordPress vulnerabilities come from plugins, not WordPress core itself
- The average time between a WordPress vulnerability disclosure and active exploitation is now less than 72 hours
What Makes WordPress Particularly Vulnerable?
Plugin sprawl. The average WordPress site runs between 20-30 plugins. Each plugin is maintained by a different developer with different security practices, different update schedules, and different levels of ongoing support. A single abandoned or slow-to-patch plugin can compromise the entire site.
Theme vulnerabilities. Many WordPress themes include their own PHP code, JavaScript libraries, and database interactions. Premium themes that are not kept updated can contain cross-site scripting (XSS) vulnerabilities, SQL injection flaws, and authentication bypasses.
Configuration weaknesses. Default WordPress installations expose the login page at `/wp-admin` and `/wp-login.php`, often without brute force protection. XML-RPC is enabled by default and is commonly used for amplification attacks. Directory listing may be enabled, exposing plugin and theme versions to anyone who looks.
Shared hosting environments. Many small business WordPress sites run on shared hosting where one compromised site can potentially affect others on the same server.

What Happens When a WordPress Site Gets Hacked?
The consequences extend far beyond having your website defaced. Modern WordPress attacks are sophisticated and business-impactful:
SEO Spam Injection
Attackers inject hidden content and links into your pages, redirecting your Google rankings to pharmaceutical, gambling, or other spam sites. This can take months to recover from and damages your domain authority permanently.Malware Distribution
Your business website becomes a vehicle for distributing malware to your visitors -- your clients and prospects. Google will flag your site with a "This site may be hacked" warning, devastating your online reputation.Credential Harvesting
Attackers modify your login forms or create convincing phishing pages hosted on your domain to steal credentials from your users, employees, or customers.Backdoor Installation
Even after you clean a hacked WordPress site, attackers often leave hidden backdoors in obscure files or database entries. Without a thorough forensic cleanup, they can return at any time.Ransomware Staging
Compromised WordPress sites are increasingly used as staging infrastructure for ransomware operations, making your business potentially complicit in attacks on others.Data Theft
If your WordPress site handles any customer data, form submissions, or e-commerce transactions, attackers can exfiltrate this data, creating privacy breach notification obligations under the Australian Privacy Act.---
Why We Include WordPress Scanning in Our Security Assessment
When you run a free security scan through our platform, our scanning engine automatically detects whether your domain is running WordPress and performs targeted checks including:
- WordPress core version detection -- identifying if you are running an outdated version with known vulnerabilities
- Plugin enumeration -- discovering installed plugins and checking them against vulnerability databases
- Theme identification -- detecting active and inactive themes with known security issues
- Configuration analysis -- checking for common misconfigurations like exposed debug logs, directory listing, and default credentials
- Known exploit matching -- cross-referencing your WordPress installation against actively exploited CVEs

The Patching Problem: Why Businesses Fall Behind
If patching is so important, why do so many businesses run outdated WordPress installations? The answer is usually a combination of these factors:
Fear of Breaking Things
WordPress updates -- especially plugin updates -- can and do break sites. A plugin update might conflict with another plugin, change a page layout, or introduce a bug. Without a testing process, many businesses avoid updating because the last time they did, something went wrong.No One Is Responsible
Many small businesses had their WordPress site built by a freelancer or agency years ago. That relationship may have ended. No one is actively monitoring or maintaining the site. Updates pile up, and eventually the site is running versions that are months or years behind.Lack of Visibility
Most business owners do not log into their WordPress dashboard regularly. They have no idea what version they are running, what plugins are installed, or what updates are pending. The site works, so they assume everything is fine.Plugin Abandonment
Some plugins are no longer maintained by their developers. No updates are released, even when vulnerabilities are discovered. The plugin still works, so it stays installed, but it becomes an increasingly dangerous liability.---
Why Your MSP Should Manage WordPress Patching
Managed WordPress patching through your MSP eliminates all of the problems above. Here is what professional WordPress management looks like:
Scheduled Update Cycles
Your MSP applies WordPress core, plugin, and theme updates on a regular schedule -- typically weekly or fortnightly. Updates are tested in a staging environment before being applied to production, so your site never breaks from an untested update.Vulnerability-Driven Emergency Patching
When a critical vulnerability is disclosed (especially one being actively exploited), your MSP applies the patch immediately rather than waiting for the next scheduled cycle. This is the difference between being protected within hours versus being exposed for weeks.Plugin Auditing
Your MSP reviews your installed plugins regularly, removing any that are abandoned, unnecessary, or duplicated. Fewer plugins means a smaller attack surface.Backup and Rollback
Before any update is applied, a full backup is taken. If an update causes issues, your MSP can roll back to the previous state within minutes, not hours.Security Hardening
Beyond patching, your MSP implements WordPress-specific security hardening:- Moving or protecting the login page
- Disabling XML-RPC if not needed
- Implementing Web Application Firewall (WAF) rules
- Enforcing strong password policies
- Restricting file permissions
- Disabling file editing from the dashboard
Monitoring and Alerting
Your MSP monitors your WordPress site for signs of compromise: unexpected file changes, new admin accounts, modified core files, or suspicious database entries. If something happens, you are notified and the response begins immediately.---
The Cost of Not Patching
To put it bluntly: the cost of managed WordPress patching is a fraction of the cost of recovering from a WordPress hack. Consider:
- Site cleanup and forensic analysis: $2,000-$10,000 depending on complexity
- Business downtime: Lost revenue and productivity while the site is down
- SEO recovery: Months of work to recover search rankings after an SEO spam injection
- Reputation damage: Difficult to quantify, but very real when clients see security warnings on your site
- Breach notification costs: If customer data was exposed, you may have legal obligations under the Australian Privacy Act
- Ongoing monitoring: After a hack, you need ongoing monitoring to ensure the attackers do not return through backdoors
