Security Hardening Case Study
This project turns repeated WordPress malware cleanup and recovery work into one portfolio-ready security case study. It is written as anonymized professional evidence, not a generic claim. The real work included cleanup, verification, hardening, and owner-facing follow-up after compromised WordPress installs.
What the work covered
- Manual malware identification and fake plugin detection
- Suspicious MU-plugin, theme, and plugin file review and removal
- Clean WordPress core and plugin reinstall workflows
- Salt-key rotation, cron reset, XML-RPC disablement, and extra
.htaccesscleanup - Database cleanup for infected revisions and stored malicious scripts
- Security-provider checks, API-call inspection, and reputation review after cleanup
- Defender hardening, audit review, and post-cleanup security recommendations
What it demonstrates
- WordPress security operations beyond plugin-level troubleshooting
- Practical incident response around compromised production sites
- Ability to separate active malware, risky remnants, and owner-action items clearly
- Clear remediation guidance after cleanup instead of stopping at file removal
Impact
- Removed fake plugins, malicious files, injected code, and suspicious admin/backdoor behavior where documented
- Reinstalled WordPress core and plugins from clean sources
- Reset cron, rotated salts, and reduced attack surface through security hardening changes
- Produced owner-facing next steps for passwords, 2FA, admin review, backups, and SEO-spam recovery
The point of this case study is not drama. It is operational discipline: identify what is compromised, remove what should not be there, restore known-good files, harden what remains, and leave the owner with a clear recovery checklist.
