Multiple Subtitles – Add or copy multiple subtitle tracks from the source file.Customizations – Customize settings on a per-group basis without modifying the preset.Groups – Put files into groups and set different settings for different groups.Scheduled Conversions - Schedule delayed conversion start.HEVC (H.265) Hardware Acceleration – HEVC (H.265) video encoding now supports hardware acceleration, resulting in conversions more than twice as fast.Image Stitching – Stitch images together into a PDF.Dark Mode – Permute now works 100% with the dark mode, even adjusting its Dock icon based on your macOS theme.It’s faster, more fluent and visually pleasing. UI Redesign – the UI has been redesigned from the ground up.Completely Rewritten – Permute 3 was started from scratch - completely new project, everything written from the ground up again.More modular and prepared for many new features to be added via later updates. It was redesigned and rewritten from the ground up. Permute 3 brings a plethora of new features and improvements. These virtual relocations are represented by the RelocationDyld object and among other attributes it contains address, size and type. The binding byte stream is represented trough the BindingInfo object.įor the rebase byte stream, the parser create virtual relocations to model the rebasing process. The export trie is represented by the ExportInfo object which is usually tied to a Symbol. In the new version of LIEF, the Mach-O parser is able to handle these underlying structures to provide an user-friendly API: Whereas in the ELF and PE format relocations are basically a table, Mach-O format uses byte streams to rebase the image and to bind symbols with addresses.įor exports it uses a trie as subjacent structure. Retrieve exported functions (or symbols).See the blog post about O-LLVM analysis: Īs mentioned in the Fortinet blog post, the library is packed. The function sub_60C0 basically iterates over the program headers to find the encrypted one and decrypt it using a custom algorithm (based on shift, xor, etc). This function is obfuscated with graph flatteningĪnd looks like to O-LLVM graph flattening passe :įortunately there are few "relevant blocks" and there are not obfuscated. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was. The tencent652524168491435794009 function basically do a stack alignment and the sub_60C0 is one of the decryption routines. BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. ![]() ![]() Now if we open the new libshellx-2.10.3.1_FIXED.so we have access to imports / exports and some sections. ![]() The script recover_shellx.py recovers the missing values, patch sections and rebuild a fixed library. dynsym address is available through the DT_SYMTAB dynstr address and size are available through the DT_STRTAB and DT_STRSZ init_array address and size are available through the DT_INIT_ARRAY and DT_INIT_ARRAYSZ entries If we open the given library in IDA we have no exports, no imports and no sections:īased on the segments and dynamic entries we can recover most of these information: shstrtab STRTAB 00000000 024268 0000b1 00 0 0 1 Key to Flags: W (write), A (alloc), X (execute), M (merge), S (strings), I (info), L (link order), O (extra OS processing required), G (group), T (TLS), C (compressed), x (unknown), o (OS specific), E (exclude), p (processor specific) There are 21 section headers, starting at offset 0x2431c: Section Headers: Name Type Addr Off Size ES Flg Lk Inf Al NULL 00000000 000000 000000 00 0 0 0.
