When I was younger, I would have loved support to build open source #OSINT tools. So we launched #OSINTGotTalent, a grant (up to €2000) to help creators turn their #OSINT ideas into reality. You’ve got talent? Let’s fund it. #infosec #opensource

Outside my #OSINT work, I’ve spent years doing physical intrusion tests, sneaking into offices & facilities to find overlooked vulnerabilities. I got to share some stories (and real footage!) on #Underscore_, the show by Micode. ➤ Watch it (in French 🇫🇷): 📽️ www.youtube.com/watch?v=L7dnmHnJbww
