In this article, we will explore the phenomenon of unknown spam numbers, understand the reasons behind their proliferation, and provide tips on how to protect yourself from falling victim to their schemes.

One key factor is the accessibility and affordability of Voice over Internet Protocol (VoIP) technology, which allows scammers to make calls using the internet instead of traditional phone lines. This makes it easier and cheaper for spammers to make calls from anywhere in the world, disguising their real location and identity. Additionally, scammers often use spoofing techniques to manipulate the caller ID displayed on the recipient's phone, making it appear as if the call is coming from a local number or a trusted organization. This deceitful tactic increases the likelihood of the call being answered, as recipients are more likely to answer calls from familiar or local numbers. Another reason for the rise of unknown spam numbers is the sheer volume of phone numbers that are available for scammers to exploit. With the proliferation of online services and databases, phone numbers are easily obtained and traded on the dark web.

This has led to an influx of phone numbers being used for spamming purposes, resulting in a flood of unwanted calls to unsuspecting individuals.

Here are some tips: Do not answer unknown numbers: If you receive a call from an unknown number, it's best to let it go to voicemail.

Be cautious with personal information: Never provide personal or financial information over the phone to unknown callers. Legitimate organizations will not ask for sensitive information over the phone.

While this may not block all spam calls, it can help reduce the number of calls you receive. Be cautious of caller ID: Remember that caller ID can be easily spoofed, so do not rely solely on the displayed number or name to determine the legitimacy of a call.
