Unicorn Wrangling 101: What is a Backdoor?


Duo Labs recently looked at some Chinese cellphones we just happened to run across, and we’d thought it would be cool to find some evil backdoors in them. We quickly discovered that between the three of us working on this we had maybe ten different ideas about what a backdoor was, and things kind of went downhill from there. But we did write up a blog post about it which hopefully some of you might find interesting. Did we cover all the possible backdoors? We’d love to hear your opinions on this.
