๐ Dynamic Analysis Techniques: Execute malware in an isolated VM and monitor its behavior with tools like Dtrace and fs_usage. Track file access, process creation, and system interaction in real-time. #DynamicAnalysis #MacReversing
๐ Understanding Mach-O Binaries: Mach-O is the native executable format for macOS. Each binary contains segments like __TEXT and __DATA. Tools like otool and MachOView help you explore these structures. #MachO #MacReversing
๐ Decrypting Apple Encrypted Binaries: Use tools like AlanQuatermainโs appencryptor to handle Appleโs encrypted binaries. A vital step in reverse engineering protected macOS software. #Encryption #MacReversing
๐ Introduction to DYLIBs: DYLIBs (Dynamic Libraries) in macOS function like DLLs in Windows. They allow shared code usage across applications. Analyzing DYLIBs is key to understanding how apps load shared functions. #DYLIB #MacReversing
๐ Manipulating Code Signatures: Use codesign -dvvvv to verify a binaryโs signature and xattr -rc to remove quarantine flags. This allows you to bypass macOS security checks like Gatekeeper. #codesign #MacReversing
๐ Mac Reverse Engineering Essentials: Reverse engineering on macOS involves understanding Mach-O binaries, DYLIBs, and key tools like Hopper, IDA, and lldb. Weโll walk through everything from static to dynamic analysis. #MacReversing #ReverseEngineering
๐ง Offset Calculators: Use to calculate the correct patch offsets in fat binaries, ensuring accurate modifications across different architectures. #OffsetCalculator #MacReversing
๐ Analyzing DYLIBs: Use otool -L to list linked DYLIBs in a Mach-O binary. Check for malicious or unexpected libraries that may indicate code injection or tampering. #DYLIB #MacReversing
๐ง Analyzing PKG Files: PKG files are XAR archives. Tools like unar help extract and analyze these packages, revealing embedded Mach-O binaries or malicious scripts. #PKGFiles #MacReversing
๐ Exploring Application Bundles: Mac apps are bundles, not single files. Use ls -laR to explore directories, focusing on Info.plist and executable files to spot suspicious activity. #AppBundles #MacReversing
๐ Comprehensive Process Analysis: Use Dtrace, execsnoop, and fs_usage to monitor process creation and behavior. Identify how malware spawns new processes and interacts with the system. #ProcessAnalysis #MacReversing
๐ Static Analysis with Class-dump: Class-dump extracts Objective-C class info from Mach-O binaries. This is essential for understanding the internal structure of macOS applications. #ClassDump #StaticAnalysis #MacReversing
๐ ๏ธ Enhanced Debugging with gdbinit: gdbinit enhances GDB with better output and useful macros. Essential for more efficient debugging when working with Mach-O binaries. #gdbinit #Debugging #MacReversing
๐จ Hex Editors for Patching: Use 0xED, HexFiend, and Synalyze It! to patch Mach-O binaries at the byte level. Modify instructions, patch functions, and bypass checks directly in the binary. #HexFiend #Patching #MacReversing๐
๐ ๏ธ Disassemblers: IDA Pro & Hopper: IDA offers deep disassembly features, while Hopper is a more budget-friendly tool with strong Mach-O support. Hopper is a great alternative if IDA Pro is unavailable. #IDA #Hopper #MacReversing
๐ก๏ธ Bypassing Anti-Debugging: Onyx-the-black-cat is a kernel module that helps bypass anti-debugging methods like ptrace. Crucial for analyzing malware that employs these tactics. #Onyx #AntiDebugging #MacReversing
๐ง Advanced Tools: Ghidra & radare2: Ghidra offers powerful disassembly and decompilation, while radare2 provides a robust framework for reverse engineering. Both are essential for in-depth analysis. #Ghidra #radare2 #MacReversing
๐ง Using lldb for Debugging: Xcodeโs lldb debugger allows you to step through code, set breakpoints, and inspect memory. Itโs essential for dynamic analysis and understanding malware behavior. #lldb #Debugging #MacReversing
๐ง Using otool & nm: otool -L shows linked libraries, while nm lists symbols within a binary. These tools are your starting point for identifying key functions and external dependencies. #otool #nm #MacReversing
