Physical access to a client’s building can offer the penetration tester a whole host of powerful attack vectors. This module will teach the student how to gain access by picking the door locks and padlocks securing the building. Yes, you read correctly! By the end of the hands on laboratory, the student will be able to open most common types of pin tumbler door locks and 90% of padlocks available on the market. Most ‘Ethical Hacking’ courses talk about the theory of physical access, the CPTE covers the practical art of physical access.
