The State of Internet Censorship in Egypt
A
groundbreaking report by OONI and AFTE uncovered anomalies on Egyptian
networks including censorship and the hijacking of unencrypted HTTP
connections for advertising and cryptocurrency mining. Even UN sites
were redirected.
Also, more than 100 news websites are blocked in Egypt, including Al Jazeera, The Huffington Post Arabic, Mada Masr, Almesryoon, Daily News Egypt, Turk Press and Iran’s Alalam News.
“The blocking
of media organizations’ websites has had a severe impact on their
operations, and some have even suspended their work altogether as a
result of persisting censorship,” said Mohammad El Taher, director of
the AFTE research unit.
While it’s been
known that Egypt has undertaken widespread censorship of websites, this
is the first time a comprehensive study of the methods of censorship
have been undertaken. Find out how Egypt censors.
How to Do Effective and Impactful Tor Research
As we mentioned in our previous post about Tor research topics,
Tor greatly benefits from the research community. When researchers work
closely with the design and development of deployed systems, this not
only results in better research, but also better systems. For project
maintainers, research that identifies vulnerabilities, creates new
solutions to existing problems, and verifies proposed designs helps
improve projects and make them safer for end users. TLS 1.3 is one
recent example of where a symbiotic research/practitioner relationship
has improved the protocol's design and safety.
However it is
all too common that good research ideas don't make their way into
practice. Within Tor, we have found that integrating new research
findings isn't seamless or predictable, and good ideas are often lost or
deemed incompatible without significantly more analysis and research.
The purpose of
this post is to discuss what good research needs to do in order to
ensure it has the best chance of being adopted by Tor or any other large
software project.
We have
structured this post in terms of an ordered list of goals for research.
Each successive goal is more difficult to accomplish than the previous
one. At the end of this post, we will look at a positive example of
excellent research that successfully accomplished all of these goals and
give overall takeaways.
Find out your list of goals, in order of increasing difficulty, when conducting relevant research.
Open Research Topics: 2018 Edition
Here we update
the list of open Tor research problems, to bring focus to specific
areas of research that the Tor Project thinks are necessary/useful in
our efforts to upgrade and improve the Tor network and associated
components and software. It is organized by topic area: network
performance, network security, censorship circumvention, and application
research. Each topic area provides information about current and
desired work and ideas. We conclude with information about doing ethical
and useful research on Tor and with suggestions on how to best ensure
that this work is useful and easy for us to adopt. Check them out.

New Onion Services Add-On: Vanguards
However, while this new protocol closes off some attacks (particularly enumeration and related targeted DoS attacks), it does not solve any attacks that could lead to service deanonymization.
The core Vanguards functionality ensures that all onion service circuits are restricted to a set of second and third layer guards, which have randomized rotation times.
If you want to beef up the security of your onion service, this add-on is for you.
