Sri Lankan Terrorists Hack Satellite
SorryTomato writes "The Tamil Tigers Liberation Front a separatist group in Sri Lanka, which has been classified as a terrorist group in 32 countries has moved up from routine sea piracy to a space-based one. They have been accused of illegally using Intelsat satellites to beam radio and television broadcasts internationally. Intelsat says that they will end the transmissions 'within days.' Intelsat has been accused of having business links with Hezbollah before, but claim that they are blameless this time and LTTE was using an empty transponder."
Hacks of satellites have been predicted by experts numerous times before; the older ones were, rather worryingly, designed mostly with security by obscurity. Need uplink codes? Probably not a problem if you can get near to the ground station with appropriate equipment, no radio transmission is 100% directional.
IIRC it was one of the Blackhat conference speakers who outlined the nasty possibility of a satellite somewhere in a geosynchronous constellation being hijacked and deliberately crashed into another one. Given that this area is fairly densely populated, the debris could start a chain reaction and do a lot of damage.
After taking a look at your past comments, it seems more likely that you just wanted to rationalize the antics of the violent insurgents that are basically destroying my native country, because you like that they're anti-American rebels. (Although they ARE part of the reason I came to the US, I have to thank them for that.)
Mods- I'm not trolling here-- look at his profile if you don't believe me.
I know, because I work for a satellite company. Communications satellites normally have no protection at all, if you know the right frequency, have a powerful enough transmitter and antenna, and know where to point your signal, you can do it. And it's *extremely* difficult to avoid, there are very few technical countermeasures. You can beam a more powerful carrier over the pirate, but this means you lose the bandwidth anyhow and, in case of an intentional interference, the pirate can just shift his frequency and start over.
It happens all the time accidentally. Sometimes amplifiers are defective, or they are inadvertently turned to the wrong frequency. These accidental interferences happen everywhere, and cost millions of dollars per year for every operator in terms of bandwidth that becomes unusable.
Since a satellite has a wide coverage area, it's very difficult to find the transmitter. There are some very expensive systems to locate interferences, they work based on small shifts in frequency and time that depend on the transmitter location, but these systems cannot locate a transmitter with an accuracy better than tens of miles. After finding the general area where the interference originates, one must sweep the whole region with a helicopter equipped with a directional antenna. Very messy and very expensive.
Very insightful, it is also exactly what is happening in Sri Lanka. I have personally witnessed a civilian being beaten up by the Sri Lankan army: on the main road connecting the capital to the parliament. People who travel to the war torn east of the country have told me such things happen regularly there. I shudder to think what happens out of sight and in more of the way places.
The LTTE are very ruthless and achieved their position partly by killing any dissenters. They are also the world leaders in suicide bombings, both in the number of attacks and the technology used. I suspect if the Sri Lankan forces had been more restrained, the LTTE's own brutality would have undermined them.
They are certainly ingenious and are unique among their peers in operating on land, sea and in the air - they recently used light aircraft to bomb an air force base, and had dropped bombs and got away before the air force get its air craft off the ground.
In the meantime, Sri Lanka faces horrible side effects from war. Corruption, vote-rigging, suppression of free speech, a rise in Buddhist fundamentalism and huge economic damage.
On a more cheerful note, its a great time to go to Sri Lanka on holiday. The hotels are dirt cheap. The conflict is localised, foreigners are not targets, and you would be safe from violence as long as you avoid the north and east of the country. The risks from Sri Lankan driving are another matter....
Posting anonymously for obvious reasons: my profile links to my blog and I do not want to make unnecessarily make enemies in Sri Lanka as I spend a lot of time there. The fact that I feel it necessary to be anonymous should tell you a lot about the state of free speech in Sri Lanka.
It might not have been approved by the higher ups either in the family/party. India's Minister for Communication Kalanidhi Maran, is a nephew of the Chief Minister of Tamil Nadu and their family owns the SunTV conglomerate. Tigers are to be feared, their pledge of alligiance to their leader Prabakaran supercedes any other consideration.
Trying hard to present NPoV without my biases. Hope I succeeded.
