Black box pentesting

In a black box pentesting session, the pentester simulates a real-world attack to gain access to a system or IT infrastructure. Thus, he opts for a pentesting approach with no information about the organization and no prior knowledge of the infrastructure. This type of pentesting is very effective because the pentester wears a black hat and uses a black hat hacker's techniques to bypass the organization's security guards. It is carried out from a black hat hacker's point of view. So, they use fingerprinting techniques to discover everything about the organization.
