Protecting Against Computer-Generated Fraud Calls: A Guide to Eliminating Number Spoofing Scams

With the rise of computer-generated, spoofed GSM numbers, fraudsters are becoming increasingly sophisticated in their attempts to reach unsuspecting victims. Unlike regular phone numbers, these computer-generated numbers can quickly change and make it difficult to block or identify them. In this article, we explore the techniques used by fraudsters and provide practical steps to help you protect yourself from these scams.

Understanding Number Spoofing

Number spoofing is the act of misleadingly displaying a phone number on the receiving end of a call. Fraudsters often use this technique to hide their identities and make their calls appear legitimate. While there are legitimate uses for number spoofing, such as emergency services or law enforcement, it is frequently employed by scammers to trick their victims into believing the call is from a trusted source.

A Two-Layered Defense System

The United States has implemented two layers of defense against number spoofing and call fraud:

STIR/SHAKEN: Caller ID validation through STIR/SHAKEN helps authenticate the source of the call. This technology ensures that the caller ID is not being spoofed. Behavioral Analysis: Networks analyze the behavior of incoming calls to identify potential scams. Calls from foreign numbers entering the US are often marked as suspicious, except in cases where the network recognizes that you are roaming.

While these systems are effective, they are not foolproof. As a result, fraudsters can still execute their scams from time to time.

Protecting Yourself from Scams

The best defense against computer-generated fraud calls is to implement several layers of protection:

Register on the National Do Not Call Registry: You can register your number for free by calling 1-888-382-1222 or using the online form at http://DoNotCall.gov. Install Spam Call Blocking Software: Consider using a spam call blocking or spoofing protection app. Both Android and iOS devices offer a wide range of options, such as the 'Blacklist' app for Android phones. Set Your Phone to Block Unknown Numbers: Block calls that are not in your contact list. This can be done through your phone's settings, and you can further refine the settings to block specific numbers. Set Up an Alternative Voicemail Greeting: Encourage callers to leave a message by customizing your voicemail greeting. This can help you remain in touch with people who need to reach you and identify potential scams.

Conclusion

Protecting yourself from computer-generated fraud calls requires a multi-faceted approach. By staying informed about the latest scams, implementing a robust defense system, and remaining vigilant, you can significantly reduce the risk of becoming a victim. Always keep your spam call blocking software up to date and regularly review your blocked numbers list to ensure you are not inadvertently blocking legitimate contacts.
