Description

This talk focuses on identifying and reporting basic physical security failures rather than advanced exploits, as these "stupid [__]" vulnerabilities pose the most significant real-world threats 0:30.

Key Takeaways:
• Simple misconfigurations like improperly wired accessibility buttons can completely bypass door security systems 2:15
• Latch bypass vulnerabilities allow anyone with basic tools to open locked doors by manipulating the latch mechanism 4:38
• Most access control alarm systems don't function as intended, with door forced alarms typically getting logged but never triggering responses 15:05
• Camera surveillance often provides little value due to poor positioning, inadequate resolution, or improper lighting 18:06

Employees should prioritize reporting these basic security failures rather than advanced exploits to get taken seriously by management 21:11.
