Currently I am patching some app in Mac OS. This app use flexnet 11.12.1, the checksum have been patched. does anyone have some advice about ecc pattern? Binary link: https://www.sendspace.com/file/p5b0qn thanks very much in advanced
Check first if the vendor is packed with upx.. You'll need to unpack then search the pubkey_verify routine.. For MacOSX x64: BA 1B 02 00 00 BE Search this pattern with idapro. Then you need to seach the beginning of this function and patch the ecc.. Good luck
How about Flexnet 11.13.1? Have any guru looked at this version? I am now working on a very important program for my profession, and would like to get some help from you. Any one knows how to patch 11.13.1?
