Social Engineering Attacks: How to Protect Your Employees

Companies may spend heavily on security systems, only for a breach to begin with a single message that looks perfectly normal or a seemingly harmless phone call. This is where the danger of social engineering lies. Rather than searching for a technical vulnerability in a company's systems, an attacker looks for the right moment to manipulate an employee into making a mistake that allows them to gain access to the company's systems.

These attacks are no longer limited to traditional methods such as email. They also reach employees through phone calls and text messages. Such attacks have recorded a click rate approximately 40% higher than simulated email phishing attacks, according to the Verizon 2026 Data Breach Investigations Report.

That is why it is important to understand how social engineering works, the tricks attackers use to exploit employees, the warning signs that can help identify an attack early, and the steps companies can take to reduce the likelihood of these attacks succeeding.

What Is Social Engineering?

Social engineering is a technique in which an attacker manipulates people and influences their decisions to gain access to information, money, or systems, rather than attempting to breach a company's systems directly.

Attackers often exploit ordinary workplace situations, such as trusting a manager, responding to an urgent request, or wanting to help a colleague. They then use these situations to persuade an employee to click a link, share login credentials, make a financial transfer, or grant access permissions that should not be provided.

As a result, an attack can succeed without exploiting an obvious technical vulnerability. The attacker obtains what they want through an action the employee takes themselves, believing the request to be legitimate.

Why Do Attackers Target Employees Instead of Company Systems?

Security systems continue to evolve, but employees still face dozens of everyday decisions that may seem routine, such as opening an email attachment, answering a call from someone claiming to be from technical support, or responding to an urgent request to transfer money. This is where cybercriminals find opportunities: a single decision made in haste or without verification can give them access to company data or systems.

The data highlights the scale of this risk. A report published in 2025 found that human actions and errors played a role in approximately 60% of data breaches, including incidents involving stolen credentials and deceptive messages or links.

This does not mean that employees are always the weakest link. Rather, it demonstrates how effectively attackers can exploit normal workplace behaviors, such as the desire to complete tasks quickly or help others.

What Are the Most Common Types of Social Engineering Attacks?

Social engineering techniques vary depending on how an attacker attempts to deceive an employee and achieve their objective. Attackers may impersonate a trusted person or organization, exploit curiosity and urgency, or use fraudulent messages and phone calls. Some of the most common techniques include:

• Phishing:
• Phishing involves sending messages or creating fake websites that appear to belong to a trusted organization. The goal is to steal login credentials or financial information, or persuade users to open a malicious link or file.
• Different forms include Spear Phishing, which targets specific individuals; Whaling, which targets senior executives; Vishing, which uses fraudulent phone calls; and Smishing, which uses deceptive text messages.
• Pretexting:
• The attacker creates a convincing story or situation to persuade the victim to share information they are not authorized to access. For example, they may claim to be conducting an internal audit or say they need specific information to complete a particular procedure.
• Baiting:
• The attacker exploits the victim's curiosity or desire to obtain something useful, such as free software, an enticingly named file, or a USB drive, to encourage them to run malicious content.
• Quid Pro Quo:
• The attacker offers a service, assistance, or another benefit in exchange for sensitive information or access to an account or system.
• Tailgating / Piggybacking:
• This attack takes place inside a company's premises. An unauthorized person follows an employee through a secured door after the employee uses their access card, gaining entry without having the necessary authorization.

How Has Artificial Intelligence Changed Social Engineering Attacks?

Artificial intelligence has not fundamentally changed the methods used in social engineering, but it has made attacks faster and more precise. Instead of spending a long time crafting a message or impersonating a specific person, an attacker can now generate more convincing content and personalize it for a large number of people with less effort and cost.

• Personalizing Attacks at Scale:
• Creating a convincing message for a specific employee once required considerable time spent researching and gathering details. Today, large amounts of publicly available information can be analyzed quickly and used to create content tailored to a person's role, work responsibilities, and company context. This allows attackers to launch more personalized attacks in less time.
• Reducing the Warning Signs of Fraud:
• In the past, grammatical mistakes and unnatural wording could raise suspicions about phishing messages. Today, AI can generate polished, convincing messages and adapt their tone to suit the targeted person or organization. This makes it much harder to identify fraudulent messages based on writing style alone.
• Making Impersonation More Realistic:
• AI tools can imitate voices and images convincingly. Therefore, when receiving a sensitive request, recognizing someone's voice or appearance is no longer enough to establish their identity. The request should be verified through another channel, such as calling the person using a previously known phone number or requiring a second approval.

How Can Companies Protect Their Employees from Social Engineering?

• Train Employees Using Realistic Scenarios:
• Rather than relying solely on annual theoretical training, companies should use short, recurring sessions and realistic simulations involving phishing emails, phone calls, and text messages. Scenarios should reflect the responsibilities of each department, and simulation results should be used to improve future training.
• Establish a Standard Procedure for Verifying Requests:
• Any request involving money transfers, changes to supplier details, sharing login credentials, or granting access permissions should never be carried out based on a single message or phone call. Instead, it should be verified through a separate, previously established channel, such as calling a number listed in the company's directory or obtaining a second approval.
• Limit Access Privileges:
• Give each employee only the permissions necessary to perform their job. Excessive privileges mean that compromising a single account could give an attacker access to more areas of the company. This risk can be reduced by implementing multi-factor authentication and monitoring accounts with sensitive privileges.
• Use Tools That Prevent Attacks from Reaching Employees:
• Companies can use security systems that detect fraudulent emails, suspicious links, and malicious attachments before they reach employees' inboxes. Multi-factor authentication should also be enabled so that a password alone is not sufficient to access an account if an attacker obtains it.
• Do Not Neglect Physical Security at the Workplace:
• Employees should understand that social engineering does not happen online only. Companies should control visitor access, prevent unknown individuals from following employees into restricted areas, ensure screens are locked when unattended, and avoid leaving sensitive information exposed.

What Should You Do If an Employee Falls for a Social Engineering Attack?

1. Report the Incident to the Security Team Immediately:
2. Explain what happened, when it happened, and whether a password was entered, a verification code was shared, or a suspicious file was opened.
3. Preserve Evidence Before Deleting Anything:
4. Keep the suspicious message, link, attachments, and call or text message logs. This evidence helps the security team understand how the attack occurred and identify what needs to be investigated.
5. Secure the Affected Account:
6. Change the password, revoke active sessions and access tokens, review registered authentication methods, and check for any applications or permissions the employee did not add.
7. Check What the Attacker Did Within the Account:
8. Review login activity, sent messages, email forwarding rules, permission changes, and any unusual access to files or systems.
9. Inspect the Device if a File or Program Was Executed:
10. If the employee opened an attachment, installed software, or executed a suspicious command, the device should be examined and isolated when necessary before being returned to normal use.
11. Assess the Damage and Monitor the Account After Recovery:
12. Identify the systems and data that may have been accessed, remove any mechanisms the attacker may have left behind to regain access, and monitor the account for a period after the incident to ensure that no further suspicious activity occurs.

If the attack involved a financial transfer or the exposure of sensitive data, the company should immediately contact the relevant financial institution, legal team, and appropriate authorities in accordance with its incident response procedures.

Frequently Asked Questions

• Does Multi-Factor Authentication Completely Prevent Social Engineering?
• No. Multi-factor authentication (MFA) significantly reduces the risk of stolen passwords being used to access accounts, but it does not prevent every form of social engineering.
• An attacker may trick an employee into approving an MFA request or sharing a temporary verification code. Some financial fraud and identity impersonation attacks may not require account login at all.
• Therefore, companies should consider using phishing-resistant multi-factor authentication alongside independent verification procedures.
• I Clicked a Phishing Link but Did Not Enter My Password. Should I Report It?
• Yes. Clicking a link alone may expose your device or account to risk, even if you do not enter any information. The link may contain malicious content or be used to collect information about your device and browser.
• Report the incident immediately so the security team can inspect the link and device, check for suspicious activity, and prevent the attack from reaching other employees.
• Can Social Engineering Happen Without the Internet?
• Yes. Social engineering is not limited to email. It can also involve tailgating into restricted areas, impersonating a supplier or employee, stealing documents, or looking at employees' screens.
• These techniques all rely on exploiting human behavior and gaining direct access to people or physical locations.

Ultimately, falling victim to a social engineering attack does not depend solely on how sophisticated the attacker is. It also depends on the opportunities left open by everyday workplace procedures. Every sensitive request that bypasses verification and every permission that exceeds what is necessary can become an opportunity for an attacker.

Therefore, it is not enough for a company to recognize the different types of social engineering attacks. It must continuously review how requests are processed, how access permissions are granted, and how unusual situations are handled. The strongest defense is to make continuous verification an integral part of the way the organization operates.
