xbox unhackable..?
Apparantely, its suppose to be generically unhackable. See article..
http://arstechnica.com/news.ars/post/20050910-5296.html However, since its release , a full game dumper has been made and released via underground group PI. Also posts such as this have been popping up. http://www.xboxhacker.net/forums/index.php?topic=57.0 Now with MS's track record on piracy and security how long will they last? Unhackable? Hm.. dont think so. Lets see how long it lasts. Now question here, anybody have any ideas on how to approach this hack, as the checksums are within the actual cpu core. "possible attack HV code can read itself, and can read unencrypted data in RAM, like plaintext hashing change single bits -> destroy 16 bytes in hypervisor at system call address SC illegal instruction do this over and over again might be a jump instruction 32 MB of NOPs then out code destroy hope that it's jump there can be no protection if network writes because security system is in the CPU this needs to work ONCE to dump the Hpossible attack HV code can read itself, and can read unencrypted data in RAM, like plaintext hashing change single bits -> destroy 16 bytes in hypervisor at system call address SC illegal instruction do this over and over again might be a jump instruction 32 MB of NOPs then out code destroy hope that it's jump there can be no protection if network writes because security system is in the CPU this needs to work ONCE to dump the HV" this was the posters suggestion. The key to this is dumping HV and understanding points of attack. |
