Do you know all of the data in that hidden interface can help you make your home Internet more reliable and even faster? I’m going to walk you through logging into the cable modem interface and detail what that gibberish means, but first. Please note do not abuse this functionality. If users abuse this the functionality can be taken away so only use it responsibly and respectfully. It is frustrating to not have

DOCSIS 4.0

Mia Colabrese2020-05-18T11:03:39-04:00February 20th, 2020|

Evolve or Die: Can DOCSIS 4.0 Compete with Fiber? The Telecommunications Act of 1996 forever changed the cable industry. It allowed cable and telecom to directly compete with each other. Data-Over-Cable Service Interface Specifications (DOCSIS) was already in development which enabled the cable industry to provide high speed data and later voice-over-Internet protocol (VoIP). It has been over a 20-year competition between telecom and cable operators, one that the cable industry has done quite well with and the telecom industry has struggled to keep up. The question we face is

Cable Haunt: Exploiting DOCSIS Modems

Mia Colabrese2021-12-15T10:13:01-05:00January 21st, 2020|

*Updated* (see patch for Cable Haunt at end of post) Cable Haunt is the fancy name given for a vulnerability recently disclosed by a group of researchers at Lyrebirds in Denmark exploiting DOCSIS modems. Cable Haunt affects cable modems using the Broadcom chipset specifically having the built-in spectrum analyzer many of us in the industry are quite fond of. Typically the forward path spectrum analyzer or Full Band Capture (FBC) analyzer in the broadcom chipset is used by the industry for proactive network maintenance (PNM) applications to
