Browser extensions have quietly become one of the more dangerous and overlooked attack surfaces within the enterprise.

This in‑depth guide covers:
- A deep forensic analysis of the GhostPoster campaign, including staged payloads, obfuscation techniques, and real-world impact.
- How modern extension malware evades EDR by hiding inside legitimate browser processes and abusing trusted APIs.
- Actionable detection and threat hunting playbooks focused on manifest analysis, sideloading identification, and high‑risk behaviors.
- Clear mitigation strategies, including extension governance, default‑deny controls, and browser-layer security recommendations.
