Most WordPress hacks exploit outdated software or weak passwords rather than sophisticated attacks, so the fixes are mostly about consistent basic upkeep.
1. Keep WordPress, themes, and plugins updated
Enable automatic updates where possible, since outdated software is the most common entry point for attackers.
2. Use strong, unique admin passwords
Avoid the default “admin” username and use a long, unique password stored in a password manager.
3. Install a firewall plugin
Wordfence or Sucuri blocks malicious traffic and repeated login attempts before they reach your site.
4. Limit login attempts
A plugin that locks out an IP address after several failed logins stops brute-force attacks in their tracks.
5. Keep an offsite backup
If the worst happens, a recent offsite backup means restoring your site is a quick task rather than a rebuild from scratch.
Key takeaway: Most WordPress attacks are opportunistic — consistent updates and strong passwords stop the vast majority of them.
