1. Why small sites are actually more at risk
Automated attack scripts scan for “vulnerabilities,” not “fame” —The smaller the site, the weaker the defenses, and the easier it is to get swept up in mass scans. WordPress is a major target for attacks because of its massive user base and complex plugin ecosystem. Most hacks aren’t targeted attacks — they happen because no defenses were set up.
Two: 5 security bottom lines
| Bottom line | Specific approach | Frequency |
|---|---|---|
| Update promptly | Keep core, theme, and plugins up to date; delete unused plugins | Continuous |
| Full backup | Off-site backup of files and databases, with one-click recovery | Weekly |
| Least privilege | Least-privilege backend accounts, disable unused accounts, strong passwords | Continuous |
| Login and access protection | Limit login attempts, change the default login path, enable two-factor authentication | One-time + ongoing |
| Monitoring and response | File integrity monitoring, security scanning, anomaly alerts | Daily |
Update promptly It’s the most cost-effective option—the vast majority of attacks exploit publicly known vulnerabilities in older versions, so updating is like sealing off known entry points.
3. Emergency response after being hacked
| Steps | Action | Purpose |
|---|---|---|
| 1. Isolation | Disconnect network / take site offline to prevent further spread | Stop the bleeding |
| 2 Positioning | Check recent file changes, login records, and plugin vulnerabilities | Find the entry point |
| 3 Cleanup | Remove malicious code, suspicious files, and backdoors | Get to the root |
| 4 Reset | Change all passwords and keys, reinstall the core | Hidden risk |
| 5. Review | Trace the source of the vulnerability and add the corresponding protection | Prevent recurrence |
Note: Don’t just “delete and reinstall” right away — if you haven’t pinpointed the entry point, the same vulnerability will still be there after reinstalling, and it’ll get exploited again.
| Checklist | Status | Risk of falling short |
|---|---|---|
| Core/theme/plugins updated in time | ☐ | Known vulnerability exploited |
| Weekly offsite backups are recoverable | ☐ | Data loss cannot be recovered |
| Least privilege in the backend + strong passwords | ☐ | Weak passwords cracked via brute force |
| Login attempt limits / two-factor | ☐ | Brute force attack |
| File monitoring and scanning | ☐ | Long-term lurking after intrusion |
