Why WordPress Gets Attacked So Often

WordPress runs a large portion of the web, and that popularity is exactly why it is targeted. Attackers do not usually pick your site by name — they run automated scans across millions of sites looking for known weaknesses: outdated plugins, weak passwords, unprotected login pages, and misconfigured file permissions. The good news is that the same predictability that makes WordPress a target also makes it straightforward to harden.

This guide is a practical checklist. You do not need to do everything at once, but the higher-impact items near the top are worth doing today.

Layer 1: Logins and Accounts

The login page is the most attacked surface on any WordPress site.

[ ] Never use "admin" as a username
[ ] Enforce strong, unique passwords for every account
[ ] Enable two-factor authentication on all admin accounts
[ ] Limit login attempts to stop brute-force scanning
[ ] Remove unused accounts, especially old admin and developer logins
[ ] Give each person their own account — no shared logins
[ ] Use the lowest role that does the job (not everyone needs Administrator)

Brute-force attacks rely on unlimited guesses. Rate-limiting login attempts and requiring a second factor neutralizes the vast majority of automated attacks on their own.

Layer 2: Keep Everything Updated

Outdated software is the single most common cause of WordPress compromises.

[ ] Keep WordPress core updated
[ ] Update plugins and themes promptly
[ ] Remove any plugin or theme you are not actively using — deactivated is not enough, delete it
[ ] Only install plugins from reputable sources with recent update history
[ ] Avoid "nulled" or pirated premium plugins entirely — they are a common malware vector

Every plugin is code running on your site. A plugin that has not been updated in two years is a liability regardless of how useful it once was. Fewer, well-maintained plugins beat a large collection of abandoned ones.

Layer 3: File and Configuration Protection

[ ] Set correct file permissions (typically 644 for files, 755 for directories)
[ ] Protect wp-config.php from public access
[ ] Disable file editing from the WordPress admin (define DISALLOW_FILE_EDIT)
[ ] Disable directory browsing at the server level
[ ] Block PHP execution in the uploads directory
[ ] Use unique database table prefixes on new installs

If an attacker gains limited access, these controls stop them from escalating — for example, preventing them from uploading a malicious PHP file into your media folder and running it.

Layer 4: HTTPS, Backups, and Recovery

[ ] Serve the entire site over HTTPS with a valid SSL certificate
[ ] Redirect all HTTP traffic to HTTPS
[ ] Run automated daily backups stored separately from the live site
[ ] Test that you can actually restore from a backup — an untested backup is a guess
[ ] Keep backup retention long enough to recover from a compromise you notice late

Backups are your last line of defense. If everything else fails, a clean, recent, restorable backup turns a catastrophe into an inconvenience. Backups stored on the same server as the site are not real backups — if the server is compromised, so are they.

Layer 5: Server-Level Protection

This is where your hosting choice does real work for you. Application-level hardening only goes so far if the underlying server is shared insecurely with hundreds of other accounts.

[ ] Per-client isolation so a neighbouring compromised site cannot reach yours
[ ] A web application firewall to filter malicious requests before they hit WordPress
[ ] Dedicated resources so one site's traffic spike or attack does not take down others
[ ] Server-level rate limiting and abuse monitoring
[ ] Automatic SSL provisioning and renewal

On TransPark, each site runs in an isolated environment rather than a shared pool, with daily encrypted backups retained for 30 days and free auto-renewing SSL. That isolation matters: on cheap shared hosting, a breach of one account can spread laterally across the server.

Layer 6: Ongoing Monitoring

Hardening is not a one-time task. Set up a rhythm:

[ ] Review user accounts monthly and remove any that are no longer needed
[ ] Watch for unexpected admin accounts appearing (a classic sign of compromise)
[ ] Monitor uptime and get alerted to outages
[ ] Periodically audit installed plugins and remove what you do not use
[ ] Keep an eye on published vulnerabilities for the plugins you rely on

The Canadian Data Angle

If your WordPress site collects personal information — contact forms, bookings, orders — that data falls under PIPEDA and, depending on your province, additional privacy law. Hardening protects the data; hosting location determines the jurisdiction it lives in. Running a hardened WordPress site on Canadian infrastructure addresses both the security and the residency sides of the same obligation.

The Bottom Line

Most WordPress compromises come down to a handful of preventable causes: outdated plugins, weak logins, no second factor, and no real backups. Work down the layers in this guide, starting with logins and updates. Pair application hardening with hosting that isolates your site and backs it up automatically, and you have closed the doors that automated attackers actually walk through.
