IoT Hacking for a Greater Good and Profit

What will happen when you lock a bunch of hackers, entrepreneurs, and mentors into a room for two full weekends, give them powerful tools, dangle a valuable prize, and ask them to come up with an idea for an industrial IoT product? This was an experiment masterminded by my dear friend from college days, Tahir Hussain, who heads a tech accelerator – Collide Village in the Dallas metroplex. And, it was executed just recently.

On a fall afternoon last year, Tahir told me about his hackathon idea and asked me to provide mentorship as well as to sponsor Zenseio IoT hardware for the event. He was lining up the leading IoT companies as partners and successful local businessmen/entrepreneurs as mentors. It sounded like an interesting idea, so I jumped on it without hesitation. More info

IoT Security and 100 Million of Volkswagens

Researchers just published a startling discovery we’d never want to read about. It turns out that 100 Million Volkswagen vehicles sold since 1995 can be relatively easily hacked to open doors wirelessly without having the key.

It turns out 100 million vehicles used only a handful of private shared keys. Once a single private key is breached, millions of vehicles are compromised. The way cryptography based on Pre-Shared Key (PSK) works is that two devices (a vehicle and a key fob, in this case) share a secure private key that was programmed at a factory or at a dealership. This private cryptographic key, along with a rolling code are used for encrypted wireless transmission of authenticated commands to open/close doors.

IoT Epoch Time Disaster? Only Time Will Tell

Ever heard of the “epoch time”? I’m not talking here about  history periods or geology. Epoch time is simply a standardized time and date reference used in UNIX and many other computers. It defines time, measured in seconds, starting from January 1, 1970 epoch. This is based on an arbitrary, somewhat historical epoch, but, what matters is that it is a commonly followed standard.
