Magnifier

Magnifier is an experimental reverse engineering user interface. Magnifier asks, “What if, as an alternative to taking handwritten notes, reverse engineering researchers could interactively reshape a decompiled program to reflect what they would normally record?” With Magnifier, the decompiled C code isn’t the end—it’s the beginning. Read more about how Magnifier can be used in the blog post announcing its release.

Building Magnifier using Presets and cxx-common

Step 1: get cxx-common.

scripts/fetch-cxx-common.sh
# This script will set VCPKG_DIR for you

Step 2: Set INSTALL_DIR and Build

export INSTALL_DIR=~/magnifier
# you also need to set VCPKG_DIR if not using the fetch script
scripts/build-preset.sh

Example Build Output

artem@beefy:~/git/magnifier$ export INSTALL_DIR=~/magnifier
artem@beefy:~/git/magnifier$ export VCPKG_ROOT=/opt/trailofbits/irene/downloads/vcpkg_ubuntu-20.04_llvm-13_amd64/
artem@beefy:~/git/magnifier$ scripts/build-preset.sh debug
