Caller ID spoofing

What is caller ID spoofing?
Caller ID spoofing is a practice of altering or deliberately forging information displayed on caller ID systems, which are systems designed to identify the source of a phone call to its recipient. The practice is used by many different institutions such as private investigators, secret buyers or prank callers for many different purposes.

Die Regeln der FCC (Federal Communications Commission) verbieten das Spoofing von Anruferidentifikationen mit der Absicht, Betrug zu begehen, Schaden anzurichten oder irgendetwas Wertvolles zu erlangen. Wenn Schaden durch das Spoofing verursacht wird, könnte der Täter für hohe Geldstrafen verantwortlich gemacht werden. Das Spoofing von Anrufer-IDs ist jedoch in bestimmten Kontexten legal, beispielsweise um eine polizeiliche Untersuchung durchzuführen.

There are several different methods that a spoof attempt can be made. One of the most popular is VOIP (Voice over Internet Protocol), which allows users to make phone calls over the Internet while configuring their outbound display ID to their own specifications. A very simple motivation for caller ID spoofing could be to trick the call recipient into thinking that a call is coming from a certain location. In this case, the area code of this location could be displayed in order to manipulate the recipient accordingly.
