In just a few minutes you can see how their GitHub testing script works, and just how quickly a knowledgeable attacker could gain … If this happens, the modem is completely vulnerable.​, If the script does not find the spectrum analyzer, it could mean that it is not looking at the correct IPs or ports. So does the conspicuous absence of the term BWAIN, confirm its use has officially been vaccinated? Or am I missing something? We have only seen the Spectrum Analyzer being hosted on "192.168.100.1" and "192.168.0.1", which is rarely the default gateway, and the script therefore only scans these IPs per default.
