Comparing the Network Behavior of Popular Browsers on First-Run

Mar 8, 2021

You can learn quite a bit about a browser from observing the requests it makes in its first moments with a new user profile. Often, a cursory examination will tell you a great deal about how the browser thinks about, and handles, user privacy and security.

Brave Private Content Delivery Network

Dec 10, 2020

Brave is a company where privacy isn’t just a feature; it’s a requirement. This is perhaps most obvious in the Brave Browser, where we block trackers, prevent fingerprinting, and include a privacy-preserving, opt-in and user-first ad-system, but Brave’s focus on privacy goes far beyond the browser.

zkSENSE: a privacy-preserving mechanism for bot detection in mobile devices

Oct 7, 2019

This research was conducted by Stan (Jiexin) Zhang, a research intern at Brave and a PhD student at the University of Cambridge, Dr. Panagiotis Papadopoulos, Security Researcher at Brave, and Dr. Ben Livshits, Chief Scientist at Brave. We gratefully acknowledge the valuable feedback of Prof. Alastair R. Beresford of the University of Cambridge. Bots are automated programs that often mimic human behavior for monetary or criminal purposes. They have become a serious and pervasive problem for many industries, especially for the online advertising market. In 2013, it was discovered that the Chameleon botnet harvested around 6 million dollars per month from advertisers. The proliferation and the wide variety of mobile devices created opportunities for fraudsters to gain profit by abusing the ad ecosystem and exploiting low-cost mobile devices. In particular, recent news has reported that phone farmers have been using bots to automate phone clicks and touch movements to generate revenue from ad views.

Most of the software you use includes some sort of product analytics, or usage data collection, as does every major browser. And for good reason — knowing which features are resonating and which need work is an important part of making software that’s a pleasure to use.
