What it is?
PE-bear is a freeware reversing tool for PE files. Its objective was to deliver fast and flexible “first view” tool for malware analysts, stable and capable to handle malformed PE files.
The PE-bear’s parser is open source: https://github.com/hasherezade/bearparser (works for windows and linux). It comes with a command-line tool (bearcommander). I am looking forward to hear any remarks!
I officially discontinued the project in April 2014 after releasing 0.3.7 (23.03.2014). However, as per user requests, in April 2018 I released a version 0.3.8 with bugfixes. That release has been downloaded 15,918 times – that exceeded my expectations. Due to the fact that this project still has a group of active users and gets positive reviews, I decided to reopen development.
…CIA uses it 😉
