SONY PS3 韌體 v3.56 版發佈一天，隨即被『破解』！

SONY 日前發佈 PS3 韌體 3.56 版，此版專門更新 *.self 檔案的數位簽章，玩家如要繼續安裝自製軟體則需要重新簽章，其餘部份則無較明顯的變動，簡單的說這個版本就是為了封殺破解而誕生的。

不過事與願違，SONY 的如意算盤僅打不到兩天，PS3 駭客 KaKaRoTo 已經宣布破解了 SONY PS3 新的系統韌體 v3.56 版，最新破解 Key 已經釋放出，目前他已經在 github 上掛出了 lv1、lv2 和 isoldr Key，並也針對 pup 解包和封包工具做出了升級，使之能正確的封包 v3.56 系統。

以下收錄 KaKaRoTo 對話摘錄：

KaKaRoTo: nice... it's full of spkg files now .. probably a new crypted pkg format
KaKaRoTo: possibly with a new signature that only ps3swu.self can read, but without the ecdsa fail
KaKaRoTo: humm.. seems I was misled, there's no spkg files in 3.56
KaKaRoTo: ok, so they added a new .self file in the PUP
KaKaRoTo: and it seems it contains a key that we don't know about
KaKaRoTo: yeah, probably a newer ps3swu.self that is more secure
KaKaRoTo: but they kept the old one for people upgrading from older firmwares
KaKaRoTo: the new ps3swu.self probably decrypts and uses the new self
KaKaRoTo: ok, so we need new keys for everything now
KaKaRoTo: I just pushed to ps3tools and ps3utils, fixes to allow pup/puppack/pupunpack to identify the new files in the pup

rms: try it.
KaKaRoTo: rms, what's that blob you pasted ?
adrianc: the new key
KaKaRoTo: ha, cool
KaKaRoTo: rms, if you know how and can extract all the new keys, please do and send them to me so I can upload to my ps3keys repo
adrianc: the new keys are all in there
rms: KaKaRoTo: i believe it's a lv2ldr key
rms: erk/riv/pub its all in one block
rms: i forgot the order its in though, it should be in that, its been a while
KaKaRoTo: I don't even know how you did to find those keys
adrianc: its in the data section of the elf usually
rms: its really simple
adrianc: after that look for references for blocks of data
rms: really KaKaRoTo, i think even you could do it
rms: adrianc: or something out of place
adrianc: helps to compare to older versions where you already know the key position
rms: and has a set of 8 00s
adrianc: KaKaRoTo 3.56 key works?
KaKaRoTo: adrianc, didn't try, not planning on trying atm
KaKaRoTo: not until I have ~/.ps3/ files prepared for me by someone

KaKaRoTo: lv2 3.56 decrypted
rms: keyset?
KaKaRoTo: pushing to github.com/kakaroto/ps3keys
KaKaRoTo: pushed
rms: ok
rms lv1 is also new
rms lv0 also
rms and also the spu stuff apparently
KaKaRoTo: humm.. I wonder who has the lv0 key
adrianc: i dont think lv0 is available

KaKaRoTo: iso keys are now pushed
KaKaRoTo: also, now, if we want to repackage things (unless they screwed up the ecdsa *again*), we'd have to change the keys in all the loaders... which means repackaging all the *ldr and iso selfs...
KaKaRoTo: so even more risk of bricking
KaKaRoTo: pushed spp keys
KaKaRoTo: the missing keys are for 'app', 'ldr' and 'rvk'
KaKaRoTo: btw.. where is that 'ldr' coming from ?
KaKaRoTo: and I can't figure out who decrypts lv0
KaKaRoTo: it can't be metldr since that one can't be changed
KaKaRoTo: and there's no lv0ldr
eussNL: bootldr decrypts lv0 afaik
KaKaRoTo: there's no bootldr either
adrianc: bootldr and lv0ldr arent in the pup
Matt_P: not part of coreos
Matt_P: and theres no such thing is lv0ldr
adrianc: apparently sony removed recovery mode
