## Quick Overview

Stéphane Fondjou (24) and Vincent Dusserre (19), founders of a cybersecurity company, share the story of how they exploited systemic weaknesses in data collection practices, particularly those involving the French employment website France Travail, to prove how easily personal data is compromised, ultimately advocating for increased digital literacy and better data protection practices.

**Key Points:**
- Stéphane Fondjou (24) and Vincent Dusserre (19) co-founded a cybersecurity company focused on raising awareness about data leaks and cybersecurity.
- The speakers recount a specific phishing campaign targeting users of France Travail (the French employment website) by using illegally obtained data.
- They successfully used data like names, dates of birth, postal codes, and gender to create convincing fake profiles and obtain the victim's professional email address.
- The phishing attack involved sending a link to a fake loyalty program sign-up page for a supermarket, which mirrored the real site, leading to data capture.
- The data harvested (including personal and professional emails) was then sold on the dark web, illustrating the real-world value of seemingly innocuous personal information.
- The presentation emphasizes the need to apply ecological principles, specifically the '3 Rs' (Reduce, Reuse, Recycle), to digital data to minimize our digital footprint and combat data over-collection.
- The speakers challenge the audience to reflect on how much personal data they willingly surrender, even for minor benefits like loyalty points.

**Context:** The presentation is given by two young entrepreneurs, Stéphane Fondjou and Vincent Dusserre, at a TEDxSaintEtienne event. They introduce themselves and immediately dive into a real-world anecdote about data vulnerability, using the French public employment service, France Travail, as a case study. Their core message revolves around the concept of digital ecology and the dangers of over-collecting personal data, which, once leaked, can be weaponized for sophisticated cyberattacks like phishing.

## Detailed Analysis

Stéphane Fondjou and Vincent Dusserre explain that they have often been called upon to help alleviate energy consumption factors, but they focus on a more pressing issue: data exploitation. Vincent Dusserre details how he and Stéphane, both founders of a cybersecurity company, successfully executed a phishing attack. They note that people often receive SMS messages or emails that seem legitimate, like being called a scammer, but are actually sophisticated traps. They specifically targeted data related to France Travail (the French employment agency), noting that 60% of the French population's data had been compromised. They then switch to discussing Alice and Bob, two ordinary individuals whose data was exploited. Bob, a 29-year-old job seeker, had his data used to purchase a car with forged identity documents. Alice, also 29, had her loan application compromised. The speakers reveal that the data taken—including dates of birth, postal codes, and professional emails—was sold on the dark web. They then present their solution, inspired by ecological principles: the '3 Rs' (Reduce, Reuse, Recycle) applied to data. They propose reducing the data we share, reusing what we have responsibly, and recycling digital waste by not leaving information lying around. They conclude by challenging the audience to consider the value of the data they give away and how easily systems can be manipulated, noting that the data they collected was so precise it could even mimic Alice's mother on the phone.

### Introduction to the Problem

- You have certainly been called a scammer or received scam SMS/emails, often because data from France Travail, affecting 60% of the French population, has been leaked or stolen.

### The Alice and Bob Case Study

- Alice and Bob, two ordinary people, had their personal data (ID, DOB, address) exploited, leading to financial fraud and identity theft, showing the real value of this data on the dark web.

### The Phishing Attack Method

- They explain how they used an AI named GPTo to aggregate stolen data to create convincing phishing campaigns, such as fake loyalty program sign-ups or even mimicking a victim's voice to deceive family members.

### The Digital Ecology Solution

- They propose applying the ecological principle of the 3 Rs (Reduce, Reuse, Recycle) to personal data to minimize digital waste and reduce our digital footprint.

### Conclusion and Call to Action

- The challenge is to become responsible digital citizens by reducing the data we share and learning to recognize manipulation, even when it seems benign (like loyalty programs or pizza orders).
