Comment retrouver quelqu'un qui se croit intraçable ? (Sensibilisation OSINT)

He followed ALL my security rules. Different usernames, two separate email addresses, cleaned EXIF ​​data, profile locked everywhere. Four hours later, I had his address. And the worst part? It didn't even come from him. In my last OSINT video, I showed you how to track down someone who isn't suspicious. Many of you commented, "What if the target was careful?" This video is the answer. Today, we're taking it to the next level: finding someone who followed all the OPSEC rules. Compartmentalized usernames, ProtonMail for leisure, photos without EXIF ​​data, locked LinkedIn profiles. The perfect picture of a "web ghost." And yet, in just 4 hours, starting with a single username I came across in the comments, I found his full identity, his neighborhood, his street, and even his usual bar. How? Thanks to techniques that OSINT popularizers rarely discuss: Discord snowflake analysis, stylometry, time-stamping, PDF metadata exploitation, and above all—the weak link that no one truly controls: your social circle. You'll understand why, even with excellent digital hygiene, you remain vulnerable. And most importantly, how to minimize this attack surface. ⚠️ Legal reminder: Marc is a 100% fictional character. All the accounts shown are sockpuppets that I created myself and will be deleted. No one is being targeted in real life. OSINT is legal—using it to cause harm is doxxing, punishable under Article 223-1-1 of the Penal Code (3 years imprisonment, €45,000 fine).
