You Should Know:
Address sanitizers are critical tools for identifying memory corruption vulnerabilities in kernel extensions (KEXTs) on macOS. Pishi Reloaded enhances binary-only analysis, making it invaluable for security researchers and penetration testers.
Key Features of Pishi Reloaded:
- Binary-Only Analysis: Works without source code, ideal for reverse engineering.
- macOS KEXT Support: Specifically designed for kernel extensions.
- Memory Error Detection: Catches use-after-free, buffer overflows, and other memory issues.
Practical Usage:
Installation (macOS):
Clone the repository git clone https://github.com/r00tkitsmm/Pishi-Reloaded.git cd Pishi-Reloaded Build the tool (requires Xcode) make Run against a KEXT binary ./pishi-reloaded /path/to/kext.bin
Common Commands for macOS Security Testing:
List loaded KEXTs kextstat Unload a suspicious KEXT sudo kextunload -b com.example.kext Check for memory leaks with Pishi ./pishi-reloaded --leak-check /path/to/kext
Linux Alternatives (for Comparison):
Use Valgrind for Linux kernel modules valgrind --tool=memcheck --leak-check=yes /path/to/module.ko Check kernel addresses sudo cat /proc/kallsyms | grep vulnerable_function
Windows Memory Analysis (Cross-Reference):
List loaded drivers driverquery Scan for vulnerabilities with WinDbg !analyze -v
What Undercode Say:
Pishi Reloaded fills a critical gap in macOS security research by enabling deep binary analysis without source access. Combining it with traditional tools like `kextstat` and `Valgrind` strengthens vulnerability detection across platforms. Always verify findings in a sandboxed environment before real-world exploitation.
Expected Output:
[Pishi-Reloaded] Scanning kext.bin... Detected potential buffer overflow at 0x7fff12345678 [bash] Use-after-free in function _kext_internal_call
