In this age and time when the usage of mobile phones has increased, so has the mobile phone crimes. With an increasing amount of hybrid/remote work environments, online shopping, and primarily online investing in cryptocurrencies and traditional equity investments, our phones are becoming more targeted and vulnerable due to limited security measures by the individuals, on their devices and with the traditional mobile service provider. That is what makes cell phone numbers vulnerable to security threats.

Not securing your phone number may end up in a huge financial and data loss.

Hackers take advantage of that and do much more harm and damage with little effort using your cell phone number.

How Do Hackers Steal Cell Phone Numbers?

First things first, can someone steal your phone number?

The short answer is Yes.

While many people think that sharing a phone number is harmless, it's a crucial piece of information for hackers. In fact, cell phone numbers can be considered even more critical than a SIN number as so much valuable and personal information is verified with cell phone numbers.

More surprising is how easily hackers and fraudsters can steal cell phone numbers. But how do hackers steal phone numbers, and how do they use them to harm the victims?

It's easier than you think.

Mobile number hacking has been increasingly reported all over the world. Here is the most common way hackers find the mobile phone numbers of the victims:

  • Phone numbers are linked to several online accounts
  • Mobile apps ask for a number for verification along with other personal information
  • Creating a profile on online social media requires a phone number
  • Banking and other apps request personal information, including your phone number 
  • You add your numbers to review products or services
  • Your number is available on your website, business card, and more.

Once the hacker gets their hand on your phone number, here's what they can do with it:

Port Out Scams

Porting is when a hacker sends the phone number to a new network operator. This fraud is a massive security threat in the telecommunication industry. A fraudster can receive personal information, contact your cell phone operator, and transfer your phone number to a different SIM card. The fraudster can effortlessly impersonate you and use your number for scamming and other nefarious purposes.

SIM Swapping

You use your phone number to verify different accounts, apps, and online platforms. To sign-up for a 2FA authentication, you also use your phone number for login verification or account access. In SIM swapping or SIM card replacement, your number is used to get two-factor authentication codes to access account information easily. After SIM swapping, hackers can drain your bank account, humiliate you online, and steal sensitive data.

Therefore, it is essential to practice the best habits for phone number protection.

Who is At Higher Risk of Getting Their Phone Number Stolen?

The straightforward answer is that anyone with:

  • High net-worth (money in the bank account), mainly if they invest in cryptocurrencies, 
  • High-profile individuals like executives and celebrities, and people,
  • Organizations who have direct access to sensitive customer information and,
  • Companies' trade secrets, such as law, accounting, hedge funds, government organizations, and even software companies, are at higher risk.

Mobile phones are part of the necessity like food and clothes. Not only for adults, but it has become a must-have device for kids and teenagers. While cell phones are suitable for educational, communication, and business purpose, they can be dangerous if not used correctly. There are risks and pitfalls in using a mobile phone the wrong way, so learning and teaching mobile phone security to youngsters is essential.

Moreover, hackers are no longer satisfied with phishing emails and are now sending text messages to trick people into clicking fake links. This also alerts the hacker that the cell phone number is active and can be used for fraud and hacking.

Many people complained that they were the victim of cell phone number attacks. But a particularly fierce wave of attacks has hit those with the most valuable online accounts: virtual currency. 

The phone number hijacking attacks shed light on vulnerabilities that can be exploited against almost anyone with valuable emails, sensitive information or other digital files, including business owners, bankers, activists and even journalists.

Why You Should Protect Your Phone Number?

We use phone numbers for various reasons and often share them without a second thought. We use it for sign-in websites, online shopping, services and more. App sign-up and sign-in for gaming applications and phone numbers are crucial to accessing apps. 

Without a doubt, your phone number is a more powerful ID than any other personal information; therefore, sharing a phone number has higher risks. Your phone number will be more sensitive in the coming years than your social security number.

Therefore, if your phone number is vulnerable, hackers can quickly access your online accounts and use them for malicious purposes. They can use it to impersonate you and steal your money, blackmail, and phone scams.

That is why you must protect your phone number to eliminate/reduce the damage.
