Essential for separating internet traffic from VoIP or IPTV services. The real backdoor

The use of Firmware GM219-S XPON offers several benefits, including:

The firmware runs dropbear on port 22222, but the root password is dynamically generated based on the WAN MAC + serial prefix. Tools like gm219s_pwd exist, but modern firmware (post-2022) uses an SHA256 challenge handshake. The real backdoor?
