What is Pretexting in Cyber Security?
Pretexting is a type of social engineering attack in which an attacker creates a fake scenario or story (the “pretext”) to trick an individual into revealing sensitive information or performing actions that compromise their security.
For example, an attacker may pose as a trustworthy entity, such as a bank or government agency, and use the pretext to trick the individual into giving them access to their passwords or personal information. Pretexting can be carried out over the phone, by email, or in person, and can have serious consequences for the victims and organizations targeted.

How does Pretexting work?
Pretexting works by using social engineering techniques to manipulate individuals into revealing sensitive information or taking actions that compromise their security. Here is a step-by-step explanation of how pretexting works:
- Research: The attacker researches the target to gather information about them, their job, their family, their habits, and any other relevant details that can be used to build a convincing pretext.
- Story Creation: The attacker creates a fake scenario or story (the “pretext”) that will convince the target to reveal sensitive information or take an action that compromises their security. For example, the attacker might pose as a bank representative and claim that the target’s account has been compromised.
- Contact: The attacker contacts the target using the pretext, either through phone, email, or in person. They present the story in a way that appears to be credible and legitimate, and use persuasive language and tactics to gain the target’s trust.
- Information Gathering: The attacker uses questions and statements to gather sensitive information from the target, such as passwords, Social Security numbers, or credit card information. The attacker may also use the pretext to trick the target into downloading malware or visiting a malicious website.
- Exploitation: The attacker uses the information gathered through the pretext to carry out further attacks or to steal money or sensitive information from the target. The attacker may also sell the information on the black market.
Pretexting can be difficult to detect and prevent, as it often relies on the attacker’s ability to manipulate the target into trusting them. To avoid falling victim to pretexting, it’s important to be aware of the tactics used by attackers and to never reveal sensitive information or take actions that compromise your security without verifying the identity of the person requesting it.
Examples of Common Pretexting Attacks:
Here are some common examples of pretexting attacks:
- Phishing: An attacker sends an email or text message posing as a trusted organization (e.g., a bank or government agency) and asks the recipient to click a link or download an attachment to update their information. The link or attachment is malicious and can steal the recipient’s sensitive information or install malware on their device.
- Impersonation Scams: An attacker poses as a government official, bank representative, or law enforcement officer and contacts the target by phone or email. The attacker claims that the target is in trouble or that their accounts have been compromised, and tricks them into revealing sensitive information or sending money.
- Tech Support Scams: An attacker poses as a tech support representative and contacts the target by phone. The attacker claims that there is a problem with the target’s computer and tricks them into downloading malware or giving them remote access to their device.
- CEO Fraud: An attacker poses as a CEO or high-level executive within a company and sends an email to an employee asking them to transfer funds or provide sensitive information.
- Pretexting for Password Reset: An attacker contacts a target and pretends to be a customer support representative from a trusted organization. The attacker claims that the target’s password needs to be reset and tricks them into revealing their current password.
These are just a few examples of the types of pretexting attacks that exist. It’s important to be aware of these tactics and to never reveal sensitive information or take actions that compromise your security without verifying the identity of the person requesting it.
How to Identify and Detect Pretexting Attacks?
Here are some steps you can take to identify and detect pretexting attacks:
- Be Skeptical: Always be skeptical of unsolicited phone calls, emails, or in-person requests for sensitive information or actions that compromise your security. Be cautious of requests that create a sense of urgency or pressure, and verify the identity of the person making the request before taking any action.
- Verify the Sender’s Identity: Before revealing sensitive information or taking an action that compromises your security, verify the identity of the sender. This can be done by calling the organization directly using a number found on their official website, or by checking the email address of the sender to see if it’s from a legitimate source.
- Use Two-Factor Authentication: Where possible, use two-factor authentication to secure your accounts. This adds an extra layer of security and helps to protect your information from being accessed even if your password is compromised.
- Educate Yourself: Stay informed about the latest tactics used by attackers, and educate yourself and others on how to identify and avoid pretexting attacks. Regular security awareness training can help employees recognize and respond to these types of threats.
- Monitor Your Accounts: Regularly monitor your accounts and transactions for any unusual activity. This includes checking your credit reports and monitoring your bank and credit card statements.
- Report Suspicious Activity: If you suspect that you’ve been a victim of a pretexting attack, immediately report it to the relevant authorities and take steps to secure your accounts and information.
By following these steps, you can help to reduce your risk of falling victim to a pretexting attack and protect your sensitive information. However, it’s important to keep in mind that attackers are constantly developing new tactics, so it’s essential to remain vigilant and take steps to protect yourself and your information.
How to Prevent Pretexting?
Pretexting is a form of social engineering where an attacker creates a false scenario or identity to gain access to sensitive information. To prevent pretexting in cyber security, the following steps can be taken:
- Educate employees: Train employees to recognize pretexting attempts and how to respond appropriately.
- Verify identities: Verify the identity of an individual before sharing sensitive information.
- Implement security policies: Implement strict security policies that prohibit employees from sharing sensitive information without proper verification.
- Use technology: Implement technical measures such as multi-factor authentication and encryption to protect sensitive information.
- Monitor for suspicious activity: Monitor for any suspicious activity, such as unusual login attempts or data transfers, and take appropriate action.
- Be cautious of unexpected requests: Be cautious of unexpected requests for sensitive information, especially if the request comes from an unfamiliar source.
- Report incidents: Encourage employees to report any suspected pretexting incidents to the security team for investigation.
