what is byor fr?

This repository is a curated reading list, not a piece of software, that collects writeups, research, tools, and proof of concept code about a category of security bypass technique called Bring Your Own Reputation, or BYOR. The core idea it documents is that many security defenses on Windows and the web decide whether to trust a file or website based on reputation signals, such as how old a file is, how many people have downloaded it, whether it carries a valid digital signature, or how a domain has behaved in the past. Attackers can sometimes sidestep these checks not by building trust from scratch but by hijacking trust that already exists, for example reusing an old signed program, a purchased certificate, or a popular cloud subdomain. The list is organized by defense mechanism. It covers Windows SmartScreen and the Mark of the Web flag that browsers attach to downloaded files, ways attackers have bypassed that flag using container file formats like ISO or VHD disk images, Windows Defender Application Control policies, the newer Smart App Control feature, and Google Safe Browsing along with broader domain and email reputation systems. It also covers abuse of trusted cloud hosting platforms, malicious advertising networks, and trust placed in already popular websites, plus a section on abusing trust within the software supply chain itself, such as compromised maintainer accounts. Each section links out to external blog posts, security research reports, published CVE writeups, and open source proof of concept tools that demonstrate a specific technique, along with a mapping to the industry standard MITRE ATT&CK framework for classifying attacker behavior. The README frames this explicitly as research material: understanding how reputation based defenses can be bypassed so that defenders, red teams, and security researchers can recognize and close these gaps. There are no installation instructions because the repository itself is just a structured index of links, and it accepts community contributions of new techniques and sources.
