How Phone Spoofing Works: The Call That Can Ruin Your Financial Life

Phone spoofing has become one of the most dangerous and common fraud techniques in recent years. While many people may think that phone scams are easy to detect, the truth is that cybercriminals have refined their methods to such an extent that it is often very difficult to distinguish between a legitimate call and a fraud attempt. In this article, we will break down how spoofing works, present real cases of victims, and offer practical advice to help you avoid being deceived by this growing threat.

What is phone spoofing?

Spoofing is a technique through which cybercriminals impersonate the identity of a trusted source, such as a bank or financial institution, in order to deceive victims and steal sensitive information. Scammers use phone calls and SMS messages to simulate that they are a legitimate source, often managing to catch the victim off guard. This type of fraud affects not only ordinary people but also businesses that have access to large sums of money.

The process of phone spoofing is usually elaborate and multifaceted. It starts with a call or an SMS that appears to come from a trusted source, such as a banking institution. The scammers inform the victim that their account has been compromised or that unauthorized access has occurred, creating a state of alarm in the person.

Next, the criminals redirect the victim to a fraudulent website that mimics the bank’s site and request that they enter their banking credentials. Finally, the criminal asks, via a phone call, for the keys or codes needed to “resolve the issue,” at which point the victim’s funds are transferred to accounts controlled by the scammers.

Real cases of phone spoofing

Cases of phone spoofing are on the rise and affect both individuals and businesses. According to reports from the National Police, more than 200 people have been arrested for being involved in scams exceeding 900,000 euros. Victims of these scams often face irreparable losses, as they frequently do not know what to do when they realize they have been deceived.

Case 1: The “bank alert” scam

A clear example of how spoofing operates was the case of Ana, a 43-year-old woman who received an SMS informing her that her bank account was being used in a fraudulent attempt. The message, which seemed legitimate, included a link to what appeared to be the official website of her bank. Upon accessing this page, Ana entered her username and password, unaware that it was a cloned website.

Shortly after, she received a phone call from a supposed bank employee who asked her to provide more details about her account to “protect it.” Confident due to the official tone of the call, Ana provided the information. A few hours later, when she checked her bank account, she noticed that more than 3,000 euros were missing. When she contacted the bank, she realized she had fallen victim to a spoofing scam.

Case 2: Business fraud

Another story, this time targeting a medium-sized business, occurred in 2020 when scammers impersonated a bank executive who worked with the company. The call requested that the company’s CFO transfer a considerable sum of money to a “secure” account, due to a supposed security breach. The director, trusting the information and following the instructions from the call, completed the transfer without consulting anyone else. In the end, the company lost over 50,000 euros.

The strategy behind spoofing: How do scammers do it?

Phone spoofing uses various techniques to deceive the victim. The process relies not only on a false call but also on a series of tactics that may include fraudulent SMS messages, false emails, and the creation of cloned websites. Here’s a typical outline of how a spoofing scam works:

  1. Impersonation: Criminals use tools to modify the phone number that appears on the caller ID of the recipient, making it look like an official number from a banking entity.
  2. Fraudulent SMS: The message the victim receives usually appears legitimate, even featuring the logo and official design of the bank. It warns of unauthorized access to the account and provides a link to “resolve” the issue.
  3. Cloned website: The website linked in the message is an exact replica of the bank’s page. The victim enters their data without knowing they are being directed to a fraudulent site.
  4. Phone call: Once the criminals obtain the victim’s credentials, they make a phone call to request even more information, such as security codes or additional passwords.
  5. Funds transfer: Finally, the criminals gain access to the bank account and make money transfers to accounts under their control.

Tips to avoid falling victim to phone spoofing

Phone spoofing can be very difficult to detect, but there are steps you can take to protect yourself. Here are some practical tips to help you avoid becoming a victim of this scam:

  1. Be cautious of urgent messages: If you receive a message or a call from your bank requesting urgent information, don’t take it lightly. Banking institutions will never ask for confidential information over the phone or via SMS.
  2. Always verify the link’s URL: If you receive a link in a message, carefully check the URL. Ensure that the address is legitimate and corresponds to the official bank website. If in doubt, type the URL directly into the browser instead of clicking the link.
  3. Use two-factor authentication (2FA): Always enable two-factor authentication on your bank accounts and other important services. This adds an extra layer of security that makes it difficult for criminals to access your account.
  4. Do not share sensitive information over the phone: If you receive a call from someone claiming to be from the bank asking for confidential information, hang up and contact the bank through official channels.
  5. Consult with the bank if in doubt: If you ever have doubts about a call or message you’ve received, contact your bank directly using the official customer service number. Do not use the numbers provided in the message.
  6. Regularly check your accounts: Periodically review your account statements and bank transactions. If you notice any suspicious activity, report it immediately.
  7. Notify the authorities: If you fall victim to a phone spoofing scam, it is important to report the incident to both your bank and the relevant authorities. The sooner you act, the greater the chances of recovering your money.

Conclusion

Phone spoofing is an increasingly common and sophisticated scam that affects thousands of individuals and businesses every year. Cybercriminals employ highly deceptive methods to steal confidential information and funds from victims, which can have devastating financial consequences. However, with the proper precautions—such as verifying the identity of the caller, using two-factor authentication, and educating yourself about spoofing tactics—you can protect yourself from these types of fraud. The key is to remain calm and be skeptical of any requests for personal or banking information.
