Find collisions between namespaces in programming languages and global TLDs. See http://j.mp/20J7HHp -- or view our RSA 2016 talk -- for details about why these collisions are a security issue.
python collide.py tlds.txt classes.txt
Given a list of gTLDs and a list of classes (points in the hierarchical namespace(s) of a programming ecosystem), report collisions. Both lists should be simple text files with one item per line. Comparison is not case-sensitive.
tlds.txt is provided; you may want to refresh it if its last mod date is not recent. Sample package/class hierarchies for java are also provided, although these only include items from the standard JRE. These lists were essentially copy/pasted from oracle docs; see http://j.mp/1XC3pBL for an example.
I couldn't find an easy way to generate an analogous list for the .NET framework, but I would welcome contributions of that data -- or similar data for python, ruby, and other programming ecosystems.
You might want to add company-specific libraries and classes to the list and see what additional collisions are detected...
