⚠️ Risk & Real-World Impact
Worst Case
Malicious app could enable ADB debugging, then use ADB commands to install malware, extract sensitive data, or gain full device control without user knowledge.
Likely Case
Malicious apps in the wild could silently enable debugging to facilitate data theft or install additional payloads through ADB.
If Mitigated
With proper permission controls, only system apps with appropriate privileges could access ADB debugging functionality.
🎯 Exploit Status
Exploitation requires malicious app installation; intent-based exploitation is straightforward for attackers with app development knowledge
