Still More on News Corp. Hacking Charges
Spike and others wrote in about this ongoing saga: subsidiary of Vivendi claims that a subsidiary of News Corporation cracked their satellite TV smart cards and posted for public download. (See our previous stories.) Two new stories from the Associated Press and Yahoo note that although the two companies are apparently dropping the original lawsuit (since News Corp. is making a large investment in Vivendi), Echostar is now claiming they were hacked too and the U.S. Justice Department is investigating possible criminal charges.
But I can't see any reference to a shred of proof in these articles.
So why did I read them?

I am sure there are copyright issues here. So how come a large corporation is able to get away but Dmitri Skylarov is still in jail? It always seems to be one rule for corporations and another rule for everyone else and yet another rule for the government.
It's interesting to note that DirecTV is in the process of sending out new smart cards for all of their satellite receivers nationwide. The letter announcing that fact cites "security", but it doesn't say whose security they are worried about. Unsophisticated DirecTV users will, of course, assume it's the user's security that's at stake.

Frankly, I don't care if companies hack each other...so long as I benefit.
It was only yesterday (*not kidding*) that one of the bigger Vivendi owned satellite TV (Canalsat) upgraded it's encryption system to "Seca2".
But I'm afraid the Seca2 system is DOA as it has already been cracked by Italian Crackers.

Ultimately no security scheme based on commodity hardware is secure against a determined attack. Even the clipper chip was broken. If the adversary has a scanning electron microscope available they are going to be able to reverse engineer the chip. Ross Andersson did a paper on this a while back.
The strategy the satellite companies use today is economic rather than purely technical. What they do is to design smart cards which are subject to progressive security flaws. They then send out different variations on the smart card to different customers.
The trick is that the pirate does not know which of the flaws matter and which do not. So if the pirate clones a particular card perfectly the satellite company can respond cheaply and effectively by just replacing the small number of cards that have been compromised.
If the pirate makes a more general attack the satelite co looks for any small difference between the cloned card and the genuine cards and programs a deactivation code to take advantage.
Most cloned cards are not perfect since the pirates are in competition with each other. It is better to get a cloned card out in 3 weeks than to wait a n extra couple of months and allow a competitor to steal the market.
The satelite cos generally wait until the pirates have sold a significant number of cards before sending out the deactivation codes. This discredits the pirates with more customers. If the customers learn that using a pirate card ends up costing them more than being honest in addition to being inconvenient they are more likely to turn honest. Another trick is to disable the cards right before big events.

delight: The text of the article gets the term right, saying that their smart cards were "cracked".
dismay: The text then misuses the term again, saying Echostar was hacked.
Come on folks, if a site that supposedly is "news for nerds" can't get the term right, how is anyone else expected to?
(and don't give me the BS that hacking and cracking are the same thing)
My beliefs do not require that you agree with them.
