TiVo still uses the same encoding, however, for the media files (saved as .TiVo files). These are MPEG files encoded with the user's Media Access Key (MAK). However, software developers have written programs such as tivodecode and tivodecode Manager to strip the MAK from the file, allowing the user to watch or send the recordings to friends.
how to crack virgin tivo box
Virgin could even start decking out new customers with boxes which use a cable modem to talk with a centralized crypto server. It would make cracking virtually impossible short of someone being able to brute force the CSA payload. Once computers get fast enough to brute force the CSA encryption in realtime, then all bets are off until DVB-CSA2 turns up.
I'm not very knowledgeable about such things, but if you run the old and new encryption schemes together for a short period, and someone has cracked the old one, doesn't that make it easier to crack the new one?
Steps b & c) are common to every DVB-CSA implementation and a) is unique. A cable company can transition from one form of crypto or run a couple side by side, sending ECMs for both kinds of boxes at the same time. A cracker might be able to compromise a) in one scheme but it would not necessarily help them crack the others unless the schemes were related in some way.
Theoretically two ECMs for different boxes do contain the same descramble key so if you know the key from one ECM it might help you crack the other, but I expect that every scheme ensures to salt (put random stuff in and around the key) to stop this. More modern STBs also do 2-way crypto (i.e. they need a cable modem) so it's not enough to just read what's on the wire.
"I am having a running battle with a hacker who is able to crack a 10-character password used for Virgin or Virginmedia email in less than a day," Nick complained, saying the attacker was setting up auto-forward rules to divert his emails as well as being able to guess newly reset passwords within a day.
If you want to use existing cabling, such as HDMI or ethernet (internet) cables, check they're in good condition, with no corrosion on the connectors, or cracks or weakening along the length of the cable.
It turns out that while this file is encrypted the key is embedded in the binary. One might might expect that but, ridiculously, the key is the same for every configuration on every router which means that anyone figuring out how to crack it (as did the researchers) will have access to every router using the same firmware. 2ff7e9595c
