DVRs highly insecure

Johannes B. Ullrich, a researcher and chief technology officer for the SANS Internet Storm Center, wanted to know just how vulnerable these devices are to remote takeover, so he connected an older DVR to a cable modem Internet connection. What he saw next—a barrage of telnet connection attempts so dizzying it crashed his device—was depressing. "The sad part is, that I didn't have to wait long," he wrote in a blog post published Monday. "The IP address is hit by telnet attempts pretty much every minute. Instead of having to wait for a long time to see an attack, my problem was that the DVR was often overwhelmed by the attacks, and the telnet server stopped responding. I had to reboot it every few minutes."

Tivos don't have telnet servers do they?

I know they need connectivity to download program guides but it's regrettable that you have to have them online to connect to Tivo servers. We don't know if they're secure.
