Re: ISS SSTV Project - Computer Breach

Floyd Bixler

Clint,  being a retired IT systems Engineer and Developer I’m wondering if he really hacked himself into the ISS system (a dangerous move if he could also hack other ISS systems), or he used some other technique to disrupt the project.  One idea falls to mind with a satellite project I worked on for sending digital data streams to the war fighters in Bosnia.  We actually used a normal satellite (as a test, mind you) that just happened to be in the right place and “bounced” our signal off the satellite without actually using the satellite systems.  We actually hear this a lot when looking for Meteor bounce when, sometimes, we can hear signals bouncing off satellites and not meteors.


It would seem to me that if this guy had the right power/antenna system, he could do the same.  It would disrupt the real transmissions with his own and prevent other hams from receiving anything at all or very little.


Just a thought, but you probably have a lot more info than I do.  I hope we can figure this out.

Subject: [Work-Sat] ISS SSTV Project - Computer Breach


During the current ISS SSTV project, a Nova Scotia ham intentionally hacked* 
into the ISS' computer that was handling sending the images.

That is correct. He accessed a foreign government’s computer system - with
the intent to disrupt an official ISS project by sending out his own image(s).

Several other amateur radio operators have written that their reception of
“legitimate” images from the ISS project were interrupted by this unauthorized

The offending ham has publicly pronounced himself a hero and that his actions 
are an “experiment” worthy of merit and accolades from the amateur radio community. 
He says he is well-within his rights to access the ISS' computer without obtaining 
permission. Heck, a couple AMSAT-NA board candidates have applauded and
endorsed his activity.

Again - someone accessed another's computer without permission, interrupting 
an ongoing project.

SO - What is next, if there are no repercussions to the offender? 

How about keying up on ARISS project frequencies and interrupting an ARISS 
project-in-progress? NASA and the other space agencies involved would shut 
down the ARISS schedule until they are assured that a “cure” to that malicious 
and intentional is “cured” to their satisfaction.

This offending ham’s hacking/breach should be universally condemned.

* - Some have been irritated that I use the term "hacking," to describe this 
illegal activity. According to California law, U.S. statutes, Canadian cybercrime
statutes, and international treaties, "hacking" is defined as "access to another's
computer without obtaining permission."
