Was ist Anrufer-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.
The Federal Communications Commission (FCC) rules prohibit the spoofing of caller IDs with the intent to commit fraud, cause harm, or obtain anything of value. If damage is caused by the spoofing, the perpetrator could be held responsible for heavy fines. However, spoofing caller IDs is legal in certain contexts, for example to conduct a police investigation.
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.
