Spoofing

Caller ID spoofing is a tactic where the caller manipulates the number that appears on the recipient's Caller ID display to deceive them about the caller's true identity. This method can be used to make it seem like the call is coming from a trusted source, such as a family member or a recognizable institution, to increase the likelihood that the call will be answered. For example, Jordan Harbinger discusses a situation where an individual spoofed a call to make it appear as though it was coming from their mother, which led to the call being answered 1.

In the context of corporate espionage, spoofing calls can also be used as part of rusing tactics to gather information from employees who believe they are speaking to someone within their organization. By convincing internal staff to share sensitive information under a false pretext, spoofers can extract valuable data without raising suspicion 2.
