Kicking off the final session of today at #enigma2021: Sofia Celi with ""I THOUGHT I WAS BEING STRONG WITH A COMPLICATED PERSON": THE TALES OF INTIMATE GENDER-BASED ONLINE ABUSE IN THE GLOBAL SOUTH"

[Content disclaimer: difficult content.]

usenix.org/conference/eni…
The way people use technology to abuse others is different in the global south.

This talk is a reminder that we can work together to change this.
Where does one begin?
From a personal experience to a shared experience to a community experience to a global situation

This started from my personal experience.
The people who use technology to perpetuate gender-based violence are often not sophisticated... but they are often effective.

Gender-based violence if the first cause of death of women all over the world. It is happening both in the global north and south.
Research is focused on the global north (malware, spyware), shows that attackers use phishing and social engineering

What is the state in the global south (specifically latin american region)
There is not so much research yet and it is largely local. What methodology to use?
Sexual violence [this is what I have usually seen classified as nonconsentual sexual imagery]

"They sent photos of me, intimate photos, to the WhatsApp that we have as a group at the university. They took those photos without my wanting them to"
[missed the original text in Spanish, find it in the talk]
The survivor was forced not to tell anyone because it is shameful to be seen as a sexual being in any way in this society.

The society is very misogynistic.

A survivor who committed suicide said "Sorry if I wasn't the perfect daughter" because of this shame
There are groups for men to share this type of imagery

Prevalent misogynistic messages
If women are public about the struggle or publicly a feminist you will be targeted by shame and violent acts.

Shame:
* sending sexual imagery
* hate speech
* escalates to physical violence
Women are:
* coerced into giving up passwords
* denied the use of digital devices
* denied 'digital literacy'
* denied access to digital education
The future
* need research that takes into account different regions
* privacy laws don't take gender-based violence into account
* research focusing on malware isn't enough
* concerns raised to platforms don't raise a response
* sharing of intimate media should be rethought
If we act together (juntas) we can change what is happening.

usenix.org/conference/eni…
Look for places where there are a lot of security issues being handled one-off rather than fixing the underlying issue Image
We tried to fix credential phishing mostly by telling people to be smarter, rather than fixing the root cause: people being able to use phished credential.

2-factor auth just ... fixes the problem. ImageImage

usenix.org/conference/eni…
Engineering contact-tracing apps has been a marathon

Why make them?
* manual contact-tracing became totally overwhelmed with covid cases
* can we supplement with technology? Image
Constraints: security and privacy
* protect from misuse: surveillance, target marginalized individuals, etc.
* purpose limitation by default
* hide user's identity, location, behaviour
* preserve system integrity

usenix.org/conference/eni…
This is about work done with a nonprofit to try to find a way to prevent infected people from entering a location in a privacy-preserving way.

Right now, we ask people to self-diagnose, which requires on diagnosis and truthfulness

There are stronger mechanisms like PCR tests Image

Last talk at #enigma2021 today is @iMeluny speaking about "DA DA: WHAT SHARK CONSERVATION TEACHES US ABOUT EMOTIONALITY AND EFFECTIVE COMMUNICATION STRATEGIES FOR SECURITY AND PRIVACY"

usenix.org/conference/eni…
I dreamt of being a shark scientist and worked my ass off to get a scholarship to one of the top programs. My career took a loop, but to this day I find lessons from sharks for security and privacy.
Lessons:
Incidents are emotional
* Risks will never be zero
* Public is ill-informed and fear is common
* science-based policy is not the norn
