Telnet Busybox Echo Hex Payload Write

Invocation of /bin/busybox echo -e with hexadecimal escape sequences (e.g., \x46\x46\x56...) to reconstruct raw bytes directly in the shell. This pattern is commonly used to rebuild binary payload fragments inline without transferring files in plain form. It differs from base64-encoded blobs and standard BusyBox command usage, indicating deliberate byte-level payload staging.
