Card Reader 1) Your smartcard decrypts this key (using a special sub processor in the card called the ASIC), checks if you have a legitimate subscription set in the card and if yes it returns it to your receiver in an Instruction 54. A 3M modifies the check in 2) so that the card never checks if your card is a legitimate subscription and always returns the key. In order to do this it has to MODIFY the software in the card. An Emulator SIMULATES the code in the card and forces the key to be sent, however it still needs the ASIC in a real card to actually decrypt the key. In actual fact Instruction 40 contains more than just the encrypted key Ė It also includes dynamic code. This is some extra code which executes after the key has been decrypted. This is where hashing comes into play. Firstly letís look at a 3m. Assume a section of the code in your card located at address 0000 is 11 22 33 44 55 66 77 88. An instruction 40 could include dynamic code which says after the key has been decrypted ADD whatever is at 0000 onto the key. a) In an unmodified card 11 22 33 44 55 66 77 88 will be added and will create the actual key used to encrypt your picture. b) In a 3míd card the code at 0000 has been changed to modify the check in (2) and so this modified code will get added to the key. As you can see you will not result in the same key as a) Since your 3míd card has responded with an incorrect key, your picture canít be decoded and you will get a black screen or a freeze. Now letís take a look at an emulator. An Emulator tries to simulate a real card. Since the dynamic code can contain ANYTHING, it could contain instructions that a real card can perform, but the author of the emulator didnít know about when he wrote it. The emulator may crash or perform this code incorrectly, which will corrupt your key and cause blackout/freeze. Think of PS2 emulator running on your PC. It never works with all games does it? A more serious problem comes from the fact that you can NEVER 100% simulate anything. There are always small timing or functional discrepancies, and these are exploited. Dynamic code could execute a write to memory in the smartcard but not give it enough time to actually burn into the EEPROM. An emulator would have no idea how long it takes to write to the EEPROM, and would perform the write regardless. [Incidentally this exact same attack was used against an emulator for the H card]. These are but a few examples of how emulators can be exploited. You may find it surprising to learn that dynamic code can change every 6 or 7 seconds. That means that a new dynamic Ďhashí could be executed every 6 or 7 seconds. So how many different tests can be performed to check if your card has been modified in one hour? Thatís right, over 500! The Avenger SE never modifies the code on your card, nor simulates any portions of the card. Your card always remains unmodified. As a result there are no differences that the dynamic code can detect! I have a 'sub" card, do i need to remove it from the Avenger SE and insert it into the receiver directly to receive updates? No! Your card will continue to receive all official updates while in the Avenger SE. You may use your 'Sub' card without the Avenger SE at any time if you wish, but you do not have to. Does the Avenger SE work with the No-ZKT/303 mod? Yes! The NO-ZKT/303 mod simply prevents the Zero Knowledge Test from actually being performed. they will not be wiped. With this bootloader you will be able to load a 'dead / blacklisted' BIN file to your HU card and you will not get the 744 and 745 error messages. It will also work with P4 and P5 cards, if you have a current subscription with DirecTV you can insert this device then call DirecTV and cancel your service and you will still get all your TV channels.
