💻 Affected Systems
- Atomberg Erica Smart Fan
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full device compromise allowing attacker to control fan functions, access network credentials, and potentially pivot to other devices on the same network.
Likely Case
Information disclosure of device credentials and limited privilege escalation within the fan's control system.
If Mitigated
Minimal impact if device is isolated from untrusted networks and uses strong authentication mechanisms.
🎯 Exploit Status
Exploit requires wireless proximity and knowledge of deauthentication frame crafting. Public GitHub repository contains assessment details.
