Shodan Stories Day 4: Television in Spain, Firmware Hacking in Palestine, Linux Kernels, Clone Bombs, and 14 Years of Passion

Today I saw that the fifth most searched for term on Shodan of the day was “dreambox”. What a name! I couldn’t resist! After a little digging I found that dreambox probably referred to a kind of linux-based television receiver, made by a German company with a truly fantastic logo.

I started out just searching on Shodan for “dreambox”, like so many others were doing today. It seemed like the most results were from Spain so I picked a Spanish IP and got to work with nmap.

Nmap done: 1 IP address (1 host up) scanned in 10.89 seconds

Several interesting points: telnet was open and ftp were open!, port 80 was open so it was open to being used by a browser, and it resolves to Looking into Masmovil it seems like it’s a popular provider of internet service in Spain, so the static probably referring to their static IP range that they would sell to customers. So the owner of this Dreambox probably bought a static IP for it from this stock photo hipster. I tried connecting using an ftp client, but got refused without a password, then I tried to go to it via browser. Boring log in screen, the same on 8181. Netcatting into port 21 gets a great response of 220 Willkomen auf Ihrer Dreambox. Makes sense, Dreambox is made by a German company. Netcatting into the telnet port though…

Looking at this gave me vertigo, I was staring at the Kantian sublime of my vast unknowing. “The Gemini Project”??? Dream Gaza??? “drhg”??? “clone bomb”??!?! “Time Bomb”????? I’ve now figured it all out but gosh what a story.

Dream Gaza

I wouldn’t recommend going to now, it redirects you to a malware site that could probably fill out a blog entry of its own. But checking for it on The Internet Archive’s Wayback Machine I found that from 2006 to 2013 it was a forum for Palestinian Dreambox enthusiasts who liked to tinker with their machine’s linux-based firmware. At their height they had about 60,000 members total, but it seemed like active membership spiked in 2008 and then slowly declined over the next couple of years. They talked about Islamic books, Palestinian news, 3D rendering technology, sports (there were a lot of FC Barcelona fans), space exploration, satellites’ hardware, birdwatching, but mostly they talked about what brought them together: linux, Dreambox firmware, and the TV that they watched with their hacked Dreamboxes. They would also share downloads of TV shows they recorded with their Dreamboxes, which seems to be one of the reasons for hacking the Dreambox in the first place. I wish I could read Arabic because Google translate is a little iffy, but it seems like they had a great community.

The Gemini Project

The Gemini Project was a group of linux hackers who made and distributed their own Dreambox firmware. 14 years of passion… I got emotional thinking about it. Suddenly I felt the wound of proprietary closed systems, there’s no communities forming around hacking your Amazon Echo, no joy in tinkering with your iPhone’s operating system, no feeling of ownership of or passion for your tool. At least that I know of! Maybe I’ll find some.

So I have some answers: this machine I connected to was running a version of the Dreambox firmware that had been made by the Gemini Project, which had then been futzed with by the users of the Dream Gaza forum.

The Clone Bomb

But why this firmware, in 2019, so many years since Dream Gaza has existed? I had three clues.

  1. The Dreambox Wikipedia article section on “clones” mentions that “In April 2008, Dream Multimedia allegedly introduced a time bomb into their latest flash to disable the boot loader on counterfeit models. An unofficial firmware group called Gemini who used the latest flash drivers in their firmware, found that flash corruption would be caused on clone DM500-S receivers”.
  2. The activity on Dream Gaza spiked hugely in mid 2008.
  3. A post on a satellite TV enthusiasts forum from April 2008

As far as I can tell, Dream Multimedia knew that users were out there copying their firmware and loading it onto fake Dreamboxes, which people call “clones”, so they put in a clone/time bomb into their firmware release in 2008 that would break the firmware if it were loaded onto one of these clones. The Gemini Group didn’t take out the bomb in their release of the firmware for whatever reason, so members of the Dream Gaza forum took out the bomb and put in kernel check that always runs on login to see if there is a bomb in that version of the firmware. This led a lot of people to go to the forum in mid 2008 to get that version of the firmware that has the kernel bomb check. And that firmware version is what this person in Spain is using, 10 years later.

I wonder what they’re watching. See you tomorrow.
