Microsoft PlayReady Complete Client Identity Compromise

Hello All,We have come up with two attack scenarios that make it possible toextract private ECC keys used by a PlayReady client (Windows SW DRMscenario) for the communication with a license server and identitypurposes.More specifically, we successfully demonstrated the extraction of thefollowing keys:- private signing key used to digitally sign license requests issuedby PlayReady client,- private encryption key used to decrypt license responses received bythe client (decrypt license blobs carrying encrypted content keys).A proof for the above (which Microsoft should be able to confirm) isavailable at this link:https://security-explorations.com/samples/wbpmp_id_compromise_proof.txtWhile PlayReady security is primary about security of content keys,ECC keys that make up client identity are even more important. Uponcompromise, these keys can be used to mimic a PlayReady client outsideof a Protected Media Path environment and regardless of the imposedsecurity restrictions.In that context, extraction of ECC keys used as part of a PlayReadyclient identity constitute an ultimate compromise of a PlayReadyclient on Windows ("escape" of the PMP environment, ability to requestlicenses and decrypt content keys).Content key extraction from Protected Media Path process (through XORkey or white-box crypto data structures) in a combination with thislatest identity compromise attack means that there is nothing left tobreak when it comes to Windows SW DRM implementation.Let this serve as a reminder that PlayReady content protectionimplemented in software and on a client side has little chances of a“survival” (understood as a state of not being successfully reverseengineered and compromised). In that context, this is vendor’sresponsibility to constantly increase the bar and with the use of allavailable technological means.Thank you.Best Regards,Adam Gowdiak----------------------------------Security Explorations -AG Security Research Labhttps://security-explorations.com----------------------------------Packet Storm Editor Note - below is wbpmp_id_compromise_proof.txtc:\_MNT\PROJECTS\WBPMP\code\toolkit>shell# MS Play Ready / Canal+ VOD toolkit# (c) Security Explorations    2016-2019 Poland# (c) AG Security Research     2019-2022 Polandloaded cdn      [CDN helper]loaded mspr     [MS Play Ready toolkit]loaded vod      [CANALP VOD toolkit]loaded cgaweb   [CANALP CGAWeb toolkit]msprcp> set CDM_DIR cdm\w10msprcp> identity0C86330B0E98CD7C586F336088DAFA0E4F72F3CBDC81C849F635AE556A73679F902B255736B6E891F3AF30F98B0A5DBAD9A5C7A90F8DEA029AA8FB1C95887BE3E82DFAE7A9DB21FC1ECF33C1DADC54B7msprcp> identity 0C86330B0E98CD7C586F336088DAFA0E -v[0C86330B0E98CD7C586F336088DAFA0E]PRKF version: 3   attr: 100c Unknown   data     0000:  00 04 00 00                                      ....   attr: 1000 Unknown   data     0000:  00 01 10 01 00 00 00 2c 00 02 00 80 00 01 00 00  .......,........     0010:  ea 3c 67 da 4e 43 de e0 00 00 00 10 30 e1 4c db  .<g.NC......0.L.     0020:  9d 23 9e 97 f7 1d ac 03 13 c2 2b 69 00 01 10 02  .#........+i....     0030:  00 00 00 7c 00 01 01 00 00 00 00 40 cb 27 6f 9f  ...|.......@.'o.     0040:  9f 76 46 64 54 23 19 ef 9c c7 69 0f 9c 3b e3 75  .vFdT#....i..;.u     0050:  8b d3 78 2a 8d 03 fb a8 bf 9e 1c 6d f7 10 1c 69  ..x*.......m...i     0060:  94 2c 4d 07 d9 68 8b 61 09 85 bb d3 4e e8 58 20  .,M..h.a....N.X.     0070:  e2 0c c9 bc a9 a8 1e b7 f6 59 65 7d 00 62 e4 7a  .........Ye}.b.z     0080:  4a 93 87 21 00 00 00 20 93 de eb 4b ab b4 b2 c1  J..!.......K....     0090:  71 9b 3c fc cf a8 b9 7e f2 a9 4f e1 07 39 17 fd  q.<.......O..9..     00a0:  23 10 72 8a 29 95 bf d8 00 01 10 11 00 00 00 3c  #.r.)..........<     00b0:  00 02 00 80 2d 82 c1 90 50 2c e7 55 00 00 00 10  ....-...P,.U....     00c0:  8f 03 13 45 06 c3 b4 3e fb 7f 1d 77 e8 ca 2d 07  ...E...>...w..-.     00d0:  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................     00e0:  00 00 00 00                                      ....   attr: 1009 Identities     IdentityInfo       pubkey         0000:  f0 34 a0 f4 28 79 dc a4 73 88 c8 fa a6 46 40 94  .4..(y..s....F@.         0010:  ef 10 f7 4b f4 42 5e 2e 51 c1 08 67 9d 9a 4b 2e  ...K.B^.Q..g..K.         0020:  af 2b ed 89 8e dd bb eb 1b ad 68 df 9c 33 d2 8b  .+........h..3..         0030:  1d f3 a5 77 1a d2 a0 a3 b9 4d 83 6d 24 a4 2a 03  ...w.....M.m$.*.       prvkey         0000:  31 d5 b7 ab dd 28 44 52 3b 8a ac 6c e2 c5 4e 34  1....(DR;..l..N4         0010:  61 1d 97 8f e1 4f 63 e9 c0 14 8a 83 6c 5f 3f cc  a....Oc.....l_?.
