Recently I try to use ciscocrack to reveal some password protected with CISCO xor algorithm, and I see that some long long password can not be uncipher correctly. So I update the xlat xor table from the original C file, and now it's Ok to uncipher good PSK in CISCO WIFI router :-) Remind tha it only work on : password 7, password-enable 7, ascii 7, key 7 The original table was : char xlat[] = { 0x64, 0x73, 0x66, 0x64, 0x3b, 0x6b, 0x66, 0x6f, 0x41, 0x2c, 0x2e, 0x69, 0x79, 0x65, 0x77, 0x72, 0x6b, 0x6c, 0x64, 0x4a, 0x4b, 0x44 }; can be found at PacketStorm http://packetstorm.linuxsecurity.com/Exploit_Code_Archive/ciscocrack.c Now the new was : char xlat[] = { 0x64, 0x73, 0x66, 0x64, 0x3b, 0x6b, 0x66, 0x6f, 0x41, 0x2c, 0x2e, 0x69, 0x79, 0x65, 0x77, 0x72, 0x6b, 0x6c, 0x64, 0x4a, 0x4b, 0x44, 0x48, 0x53, 0x55, 0x42, 0x73, 0x67, 0x76, 0x63, 0x61, 0x36, 0x39, 0x38, 0x33, 0x34, 0x6e, 0x63, 0x78, 0x76, 0x39, 0x38, 0x37, 0x33, 0x32, 0x35, 0x34, 0x6b, 0x3b, 0x66, 0x67, 0x38, 0x37, 0x64, 0x73, 0x66, 0x64, 0x3b, 0x6b, 0x66, 0x6f, 0x41, 0x2c, 0x2e, 0x69, 0x79, 0x65, 0x77, 0x72, 0x6b, 0x6c, 0x64, 0x4a, 0x4b, 0x44, 0x48, 0x53, 0x55, 0x42, 0x73, 0x67, 0x76, 0x63, 0x61, 0x36, 0x39, 0x38, 0x33, 0x34, 0x6e, 0x63, 0x78, 0x76, 0x39, 0x38, 0x37, 0x33, 0x32, 0x35, 0x34, 0x6b, 0x3b, 0x66, 0x67, 0x38, 0x37 }; It was extract from an uncompressed binary image of IOS 12.2(8) 0df4a70: 6473 6664 3b6b 666f dsfd;kfo 0df4a80: 412c 2e69 7965 7772 6b6c 644a 4b44 4853 A,.iyewrkldJKDHS 0df4a90: 5542 7367 7663 6136 3938 3334 6e63 7876 UBsgvca69834ncxv 0df4aa0: 3938 3733 3235 346b 3b66 6738 3700 0000 9873254k;fg87...
