Me on Belgian TV, explaining how a hacker can use insecure IoT devices to impact every other part of your digital life

Fennel Aurora’s Articles, Talks, & Media

My work is spread over multiple outlets. I often write thousands of words a day, give talks, and answer interesting questions. Most of my work is under NDA — here you will find the parts that are not. This post provides a central location to find my articles, information about talks I have given, and my press clippings.

Beyond what is below, I am fairly prolific on Twitter on all kinds of topics, mostly related to security, privacy, surveillance, and broader human rights struggles. Opinions and comments are my own, obviously!

If you like what you see and want more, please feel free to contact F-Secure PR to arrange articles, interviews, and talks. Alternatively you can contact me directly on Twitter or LinkedIn.

Get yourself cybersecure for 2020 — a brief excerpt of a quote in the UK’s The Guardian boardsheet newspaper. This was cut (and placed in a confusing context) from my original feedback to a request for comments on biometric security for mobile phones:

Again, it depends on the users’ current behaviour.
Most people do not set any code on most devices. Biometrics is more secure than no code.
Biometrics is more secure than a code of “0000”.
That said, the preference is to use a strong (meaning a long) password for all devices.
It is stronger.
It can be changed (imagine trying to change your face or fingerprints when they leak).
You often have stronger legal protections against self-incrimination.

That is not an OK price to pay for convenience.
