Voice Cloning & Deep Fake

Yesterday, I had the privilege of taking part in the "Rencontres de la Sécurité" organized by Excellium Services .

🎭 On this occasion, I was able to work and run a stand on Deep Fake and Voice Cloning. Participants had the opportunity to enjoy a unique experience: seeing their own heads and voices transformed in real time by that of Christophe Bianco.

The success of our stand testifies to the growing interest in Red Team and AI-based Social Engineering techniques.

Postmaniac

I just released my osint tool : Postmaniac

Postmaniac is a Postman OSINT tool to extract creds, token, username, email & more from Postman Public Workspaces.

It is designed to perform OSINT recognition on a target for pentesting, bugbounty and more, in order to get the maximum information from the requests left by developers on the Postman public workspaces.

If you want to know more feel free to check the tool on github : https://github.com/boringthegod/postmaniac

Thanks also to Sthack for allowing me to present this new tool in rump :D
