Vishing, short for Voice Phishing, is a type of social engineering attack that is conducted through phone calls. It is an attempt to trick individuals into revealing sensitive information such as passwords, credit card numbers, and other confidential details. This type of attack has been growing in popularity due to the widespread use of voice-over IP (VoIP) technologies, making it easier for attackers to impersonate legitimate organizations and deceive victims.

How Vishing Works

A vishing attack typically starts with a phone call from an attacker posing as a trustworthy entity such as a bank, government agency, or even a technical support representative. The attacker may try to scare the victim into providing sensitive information by claiming that their account has been compromised or that there is a problem with their computer. Alternatively, the attacker may try to gain the victim's trust by offering a prize or other incentive for providing personal information.

Once the victim has been convinced to reveal sensitive information, the attacker can use it for fraudulent activities such as identity theft, bank fraud, and other malicious purposes. Vishing attacks are becoming increasingly sophisticated, and attackers are using new technologies such as automated voice recognition systems and Caller ID spoofing to make their calls seem more legitimate.

How to Protect Yourself from Vishing Attacks

  1. Be cautious of unsolicited phone calls: If you receive a call from someone claiming to be a representative of a financial institution or government agency, hang up and call the organization directly using a verified phone number.

  1. Don't provide personal information over the phone: Legitimate organizations will never ask for sensitive information over the phone. If you are in doubt, hang up and call the organization directly using a verified phone number.

  1. Use call-blocking tools: Many phone service providers now offer call-blocking tools that can help you prevent vishing attacks.

  1. Educate employees: Train your employees to be aware of vishing attacks and to never provide personal information over the phone.

  1. Implement Two-Factor Authentication: Two-factor authentication adds an extra layer of security to your accounts by requiring a second factor, such as a one-time code sent to your phone, in addition to a password.


Vishing attacks are a growing threat to individuals and businesses alike. By being cautious of unsolicited phone calls, not providing personal information over the phone, and using call-blocking tools, you can protect yourself from vishing attacks. Additionally, educating your employees and implementing two-factor authentication can further enhance your security against these attacks.
