DOCSIS Security Illegal Wiretapping and Eavesdropping

2012-09-04T10:00:57-04:00September 4th, 2012|

Wiretapping has Evolved Before electronic eavesdropping there was just wiretapping.  When you think of wiretapping you may think of a guy in a box truck or apartment eating donuts with pizza listening in on endlessly boring phone conversations waiting to hear that one "Eureka" moment of important information.  The movie Casino comes to mind too.  The scene where Sam and Nicky have their wives talk on the phone first and then take the conversation over in timed intervals so that they can speak. So what is wiretapping?  It is

DOCSIS Security | Mac Address Cloning

2021-08-18T10:07:01-04:00August 20th, 2012|

Theft of Service via Cloning DOCSIS Security - If only cloning your favorite pet was as easy as cloning a MAC address on a cable modem.  There are dozens of websites out there giving subscribers or hackers step by step instructions on how to clone a MAC address.  Each cable modem, regardless of brand, is uniquely identified by its Cable Modems ID, or MAC address - short for Media Access Control. This address is programmed into a writable memory address of the hardware in the cable modem, and is associated with a

DOCSIS Security | Uncapping Cable Modems

2012-08-14T10:57:21-04:00August 14th, 2012|

So what is uncapping cable modems? Uncapping cable modems refers to activities performed to alter a DOCSIS cable modems settings. Plain and simple someone is messing with the cable modem's configuration file to get what they want.  So what do they want?  Greater bandwidth (the need for speed), wanting more than one public IP, or any other configurable options a DOCSIS modem can offer.  Maybe they just want to prove they can do it and or feel they are getting the shaft from their cable provider.  Really the psychology of people is

DOCSIS Network Security | Theft of Service

2021-11-24T09:10:08-05:00August 6th, 2012|

DOCSIS Network Security - It Matters! My next few posts will focus on the security issues associated with DOCSIS networks including, but not limited to theft of service, uncapping modems, illegal wire-tapping by unauthorized citizens, viewing of operating internal network infrastructure and more.  These security issues are an increasing threat as the number of DOCSIS subscribers increase, economic drivers cause subscribers to reduce costs, and un-ethical web sites provide easy step-by-step solutions for how to hack your network.  While the posts will provide a reality check for everyone

Tech Review | HbbTV, Linux & a Cool Box

2020-08-06T11:33:35-04:00July 23rd, 2012|

While checking out the booths at ANGA we came across a company by the name of Vu+.  What caught my eye was Linux written in big letters on the side of the booth.  Anything Linux will usually get me to walk into a booth.  We met with two associates one from Vu+, Victor Heo and one from Marusys, Rose Chang who gave us a tour of their companies products and introduced us to HbbTV. What is HbbTV?  Hybrid Broadcast Broadband TV (HbbTV) is both an industry standard and promotional initiative for hybrid

Tech Review | DEVISER S7000 TV Analyzer

Deviser's S7000 TV Analyzer - Many features, small package! This year at ANGA Cable show I came across a new product by DEVISER called the S7000 TV Analyzer (DEVISER OEM's their spectrum analyzer to a US based test equipment manufacturer so they have been in the business for a while and they know what they are doing).  The S7000 supports measuring ITU J.83 Annex A/B/C/D standard signals and provides Power level, MER, BER, and constellation measurements in a small package.  Also, there is an EVS tool for measuring interference

Tech Review | AND… what? Don’t let a name fool you

AND Mapping Solutions - With so much more! While at ANGA this year I was told about AND (Advanced Network Design) from a fellow convention goer.   He seemed really impressed with the company and it's product.  Honestly, I've never gotten excited over a mapping tool.  This is not normally something that I pay a lot of attention to.  Sure I'm aware of them and have experience with them but I just had visions of lot's of typing, imputing data, reviewing ports on nodes and connecting lines manually.  Not very exciting stuff.

  • DOCSIS Cable Modems go Slow

Subscribers get lower data rates than provisioned?

2020-06-09T09:36:58-04:00July 5th, 2012|

Why do my DOCSIS subscribers and their Cable Modems get lower speeds than what my DOCSIS config file says they should get? This is a common question that I am asked and it has more than one answer.  All too often the RF plant is the first to blame for low DOCSIS cable modem speeds, but in many cases the root cause of the problem can be traced back to the cable modem configuration file and/or the lack of appropriate speed test applications in the headend.  Also, some

The ByteBlower :: Blowing Bits and Bytes - Cool Tech The team at Excentis, located in Ghent, Belgium, have really outdone themselves with an incredibly cool packet generator which was on display at the Anga Cable 2012 show.  This is their second generation on the product, called the ByteBlower 2100.  It builds on the previous model, the ByteBlower 1000.  What does it do?  It generates packets of data - lot's of them and very quickly and accurately.  Why is this important?  For everyone who has a test lab and needs
