What is Port 5555?
Port 5555 is used by Android Debug Bridge (ADB) for remote TCP connections to Android devices when ADB is enabled over Wi-Fi. When a device has ADB over network enabled, it listens on this port for debugging connections. This port is frequently targeted by botnets like ADB.Miner to compromise Android devices.

Security Considerations
Port 5555 (Android ADB (Remote) / FreeBSD) is classified as critical risk. This port should not be exposed to the public internet. The service transmits data without encryption, making it vulnerable to eavesdropping, credential theft, and man-in-the-middle attacks.
Recommendation: Block this port at the firewall. Use encrypted alternatives (SSH, SFTP, HTTPS) instead.
