"Is Your Company Secure? Don't just wait for vulnerability found from security vendors, bug bounty hunters, or real-world attacks! Do it by yourself."

This session introduces the initial phase of penetration testing: reconnaissance. I will share how to use free online tools and open-source tools to uncover potential security risks. Attendees will understand how public information can be used for possible attacks.

I hope attendees will be able to conduct basic reconnaissance, find out potential security risks and reduce security risks earlier after this session.
