WordPress is powerful precisely because it's open and extensible — and that's also what makes it a constant target. Most hacked WordPress sites we've audited weren't breached through some exotic exploit. They were breached through basic, avoidable mistakes.
1. Outdated plugins and themes
A single outdated plugin with a known vulnerability is often all it takes. If you're not updating weekly — or at least reviewing what's outdated — you're leaving the door open.
2. Weak or reused admin passwords
"admin / password123" is still more common than you'd think. Every admin account should have a strong, unique password and two-factor authentication enabled.
3. No real backup strategy
A backup that lives on the same server as the site isn't a backup — it's a single point of failure. Offsite, automated, tested backups are non-negotiable.
4. File permissions left wide open
Overly permissive file and folder permissions make it trivial for an attacker who gets a foothold to modify core files. This is a five-minute fix that most sites never get.
5. No firewall or login hardening
Unlimited login attempts, no IP restrictions, no web application firewall — brute-force attacks succeed on sites with zero friction in the way.
We cover all five of these — and more — as part of our WordPress development and hardening service. If you're not sure where your site stands, request a quick security review.
