What is Social Engineering

Enhance your security awareness with our free interactive security training exercises designed to help you recognize and prevent social engineering attacks.

In today’s interconnected digital world, understanding what is social engineering has become crucial for individuals and organizations alike. Social engineering represents one of the most significant cybersecurity threats, exploiting human psychology rather than technical vulnerabilities to gain unauthorized access to information, systems, or physical locations.

What is social engineering? At its core, social engineering is the art of manipulating people into divulging confidential information or performing actions that compromise security. Unlike traditional hacking methods that target software vulnerabilities, social engineering attacks focus on the weakest link in any security system: human beings.

This comprehensive guide will explore every aspect of social engineering, from its fundamental principles to advanced prevention strategies. Whether you’re a cybersecurity professional, business owner, or simply someone who wants to protect themselves online, understanding what is social engineering and how it works is essential for maintaining digital security in the modern age.

To fully grasp what is social engineering, we must examine its multifaceted nature. Social engineering is a collection of techniques used by cybercriminals to manipulate individuals into revealing sensitive information, granting access to restricted areas, or performing actions that benefit the attacker. These techniques exploit fundamental human traits such as trust, curiosity, fear, and the desire to be helpful.

The term “social engineering” in the context of cybersecurity was popularized by Kevin Mitnick, a former hacker turned security consultant, who demonstrated how psychological manipulation could be more effective than technical exploits. When someone asks what is social engineering, they’re essentially asking about a form of confidence trick that has evolved to exploit our increasingly digital lives.

Social engineering attacks are particularly dangerous because they bypass traditional security measures. Firewalls, antivirus software, and encryption are powerless against an attack that convinces a legitimate user to willingly hand over their credentials or grant access to restricted systems. This is why understanding what is social engineering is so critical for comprehensive cybersecurity.

Understanding what is social engineering requires examining the psychological principles that make these attacks successful. Social engineers exploit several cognitive biases and emotional triggers that are hardwired into human nature:

People naturally tend to comply with requests from perceived authority figures. Social engineers frequently impersonate executives, IT administrators, or law enforcement officials to leverage this psychological tendency. When a caller claims to be from the “IT security department” and requests password verification, many employees comply without question.

The principle of reciprocity suggests that people feel obligated to return favors. Social engineers might offer small gifts or assistance before making their requests. Social proof, meanwhile, involves people’s tendency to follow the actions of others. Attackers might claim that “everyone else in the department has already updated their security settings” to encourage compliance.

Creating a sense of urgency or scarcity can override rational decision-making. Phrases like “your account will be closed in 24 hours” or “this limited-time security update” exploit our fear of missing out and pressure us into hasty decisions.

Social engineers often invest time in building rapport with their targets. They might engage in small talk, find common interests, or express sympathy for workplace challenges. This relationship-building makes targets more likely to comply with subsequent requests.

When exploring what is social engineering, it’s essential to understand the various forms these attacks can take. Each type exploits different aspects of human psychology and targets different vulnerabilities:

Phishing remains one of the most common answers to “what is social engineering” in practice. These attacks involve fraudulent communications, typically emails, that appear to come from legitimate sources. The goal is to steal sensitive information such as login credentials, credit card numbers, or personal data.

Real-world example: In 2019, Toyota Boshoku Corporation fell victim to a sophisticated phishing attack that resulted in a $37 million loss. Employees received emails that appeared to come from executives, requesting urgent wire transfers. The attackers had studied the company’s communication patterns and hierarchy to make their requests appear legitimate.

While general phishing casts a wide net, spear phishing targets specific individuals or organizations. Attackers research their targets extensively, crafting personalized messages that are much more convincing than generic phishing attempts.

Real-world example: The 2016 Democratic National Committee email hack began with spear phishing attacks targeting key personnel. Attackers sent emails that appeared to come from Google, warning recipients about suspicious login attempts and directing them to a fake login page to “secure” their accounts.

Whaling attacks target high-profile individuals such as CEOs, CFOs, or other executives. These attacks often involve impersonating other executives or board members to request sensitive information or authorize financial transactions.

Pretexting involves creating a fabricated scenario to engage targets and gain their trust. The attacker might pose as a coworker, IT support personnel, or external vendor to justify their requests for information.

Real-world example: In 2017, criminals used pretexting to steal personal information from Equifax customers. They called victims claiming to be from Equifax’s fraud department, stating that suspicious activity had been detected on their accounts. By creating this pretext, they convinced victims to provide additional personal information that was then used for identity theft.

Baiting attacks use the promise of something enticing to capture victims’ attention and prompt them to take actions that compromise security. This might involve leaving malware-infected USB drives in parking lots or offering free downloads that contain malicious software.

In quid pro quo attacks, the social engineer offers a service or benefit in exchange for information or access. A common example involves someone calling employees and offering free IT support in exchange for login credentials.

Real-world example: Attackers have been known to call companies claiming to be from tech support, offering to help with computer problems. When employees mention slow computers or software issues, the “helpful” caller offers to remotely fix the problem in exchange for login credentials.

These physical social engineering techniques involve following authorized personnel into restricted areas. Tailgating occurs without the authorized person’s knowledge, while piggybacking happens with their consent (often obtained through social manipulation).

To fully understand what is social engineering, we must examine the specific techniques and tactics employed by attackers:

Before launching an attack, social engineers conduct extensive research on their targets. This reconnaissance phase involves:

• Open Source Intelligence (OSINT): Gathering publicly available information from social media, company websites, news articles, and professional networking sites
• Dumpster Diving: Searching through physical and digital trash for sensitive information
• Shoulder Surfing: Observing targets as they enter passwords or access sensitive information
• Eavesdropping: Listening to conversations in public spaces or through electronic means

Social engineers exploit various communication channels to reach their targets:

• Email: The most common vector, used for phishing, spear phishing, and business email compromise
• Phone Calls: Voice-based attacks that leverage authority and urgency
• Text Messages (SMS): Smishing attacks that direct targets to malicious websites or phone numbers
• Social Media: Platforms used for reconnaissance and direct messaging attacks
• Instant Messaging: Corporate communication tools exploited for internal attacks

Understanding what is social engineering means recognizing these psychological manipulation methods:

• Fear, Uncertainty, and Doubt (FUD): Creating anxiety about security threats to prompt hasty decisions
• Curiosity Exploitation: Using intriguing subject lines or scenarios to capture attention
• Helpfulness Exploitation: Taking advantage of people’s natural desire to be helpful
• Authority Abuse: Impersonating figures of authority to compel compliance
• Time Pressure: Creating artificial urgency to prevent careful consideration

Examining real-world examples helps illustrate what is social engineering and its potential impact:

In July 2020, attackers used social engineering to compromise high-profile Twitter accounts, including those of Barack Obama, Elon Musk, and Bill Gates. The attack began with phone-based social engineering targeting Twitter employees. Attackers posed as IT support staff and convinced employees to provide access to internal tools.

Once inside Twitter’s systems, the attackers promoted a Bitcoin scam that promised to double any Bitcoin sent to specific addresses. The attack generated over $100,000 in Bitcoin payments and demonstrated how social engineering could be used to compromise even well-secured platforms.

The Anthem healthcare data breach, which affected 78.8 million individuals, began with a spear phishing attack. Attackers sent carefully crafted emails to Anthem employees, appearing to come from trusted sources. These emails contained malicious attachments that, when opened, installed malware on the company’s network.

The attackers had researched Anthem’s organizational structure and communication patterns to make their phishing emails appear legitimate. This case perfectly illustrates what is social engineering can accomplish when combined with technical exploits.

One of the largest bank heists in history involved sophisticated social engineering. Attackers spent months researching the Bangladesh Bank’s procedures and personnel. They used spear phishing emails to install malware on the bank’s network, eventually gaining access to SWIFT banking credentials.

The attackers’ success depended not just on technical skills but on their understanding of banking procedures and human behavior. They timed their attack for weekends and holidays when oversight would be minimal, demonstrating the strategic thinking that characterizes advanced social engineering.

The Target data breach, which compromised 40 million customer payment records, began with a social engineering attack on a third-party vendor. Attackers sent phishing emails to employees of Fazio Mechanical Services, a heating and air conditioning company that worked with Target.

Once they gained access to Fazio’s network, the attackers used those credentials to access Target’s vendor portal and eventually infiltrate Target’s payment systems. This case shows how understanding what is social engineering is crucial for managing third-party risk.

Understanding what is social engineering includes recognizing its significant business impact. According to various cybersecurity reports, social engineering attacks cost organizations billions of dollars annually and continue to increase in frequency and sophistication.

Direct financial losses from social engineering attacks can be staggering. Business Email Compromise (BEC) attacks alone resulted in losses exceeding $2.4 billion in 2021, according to the FBI’s Internet Crime Complaint Center. These attacks typically involve executives or employees being tricked into authorizing fraudulent wire transfers.

Social engineering attacks often lead to significant data breaches, exposing customer information, intellectual property, and other sensitive data. These breaches can result in:

• Regulatory fines under GDPR, HIPAA, and other compliance frameworks
• Legal liability from affected customers and partners
• Costs associated with breach notification and credit monitoring services
• Long-term damage to customer trust and brand reputation

Beyond immediate financial losses, social engineering attacks can disrupt business operations for weeks or months. Organizations may need to:

• Rebuild compromised systems and networks
• Implement additional security measures and controls
• Conduct forensic investigations to understand the scope of compromise
• Manage crisis communications with customers, partners, and regulators

The reputational impact of successful social engineering attacks can be long-lasting. Customers may lose trust in an organization’s ability to protect their information, leading to customer churn and difficulty acquiring new business.

As technology evolves, so does the sophistication of social engineering attacks. Understanding what is social engineering in the modern context requires examining how digital transformation has created new attack vectors:

The shift to cloud computing and remote work has expanded the attack surface for social engineers. Employees working from home may be more susceptible to attacks, lacking the physical security controls and IT support available in traditional office environments.

Example scenario: An attacker might call a remote employee claiming to be from the company’s IT helpdesk, explaining that they need to “verify the employee’s VPN credentials” due to a security incident. Without the ability to easily verify the caller’s identity through in-person interaction, the employee might be more likely to comply.

Social media platforms provide unprecedented amounts of personal information that social engineers can exploit. Attackers can learn about:

• Personal relationships and family members
• Work schedules and travel plans
• Interests and hobbies
• Professional connections and organizational hierarchies
• Recent life events that might create emotional vulnerability

Emerging technologies are making social engineering attacks more sophisticated and harder to detect:

• Voice cloning: AI can now replicate voices with just a few minutes of audio sample
• Deepfake videos: Realistic video impersonations of executives or public figures
• AI-powered personalization: Machine learning algorithms that can craft highly personalized phishing messages

As more devices become connected to the internet, social engineers have new opportunities to gather information and gain access to networks. Smart speakers, security cameras, and other IoT devices can provide insights into personal habits and organizational routines.

Sophisticated attackers employ advanced techniques that go beyond simple phishing emails. Understanding what is social engineering at this level reveals the true scope of the threat:

BEC attacks represent some of the most financially damaging social engineering techniques. These attacks typically involve:

1. Email Account Compromise: Gaining access to legitimate email accounts through credential theft
2. Executive Impersonation: Creating fake email addresses that closely resemble executive accounts
3. Vendor Fraud: Impersonating trusted vendors to redirect payments to attacker-controlled accounts
4. Attorney Impersonation: Posing as legal counsel to create urgency around confidential transactions

These sophisticated attacks involve compromising websites that targets are likely to visit. Instead of directly targeting the victim, attackers infect legitimate websites with malware, waiting for targets to visit and become infected.

Real-world example: In 2017, attackers compromised the website of a Ukrainian accounting software company, inserting malware that spread to thousands of companies worldwide, including major corporations like Maersk and FedEx.

Attackers increasingly target third-party vendors and suppliers as a way to reach their ultimate targets. By compromising less-secure partners, they can gain access to larger, more valuable targets.

Advanced social engineers sometimes focus on recruiting insiders rather than tricking them. This might involve:

• Blackmail or coercion
• Financial incentives for disgruntled employees
• Romantic relationships (honey traps)
• Exploiting personal financial difficulties

Different industries face unique social engineering challenges based on their specific operational characteristics and valuable assets:

Healthcare organizations are prime targets for social engineering attacks due to the high value of medical records and the critical nature of healthcare systems. Common attacks include:

Understanding what is social engineering is the first step in building effective defenses against these increasingly sophisticated attacks. As we’ve explored throughout this comprehensive guide, social engineering represents a fundamental challenge to cybersecurity because it exploits the human element that no technical solution can completely protect.

The key to defending against social engineering lies in recognizing that it’s not just a cybersecurity issue—it’s a human psychology issue that requires a human-centered solution. Organizations that successfully defend against social engineering attacks understand that technology alone is insufficient. They invest in comprehensive security awareness programs, create cultures of security consciousness, and empower their employees to serve as an effective human firewall.

What is social engineering will continue to evolve as technology advances and threat actors develop new techniques. Artificial intelligence, deepfakes, and other emerging technologies will create new opportunities for social engineers, but they will also provide new tools for defenders. The organizations that stay ahead of these trends will be those that maintain a commitment to continuous learning, adaptation, and improvement.

The most important takeaway from understanding what is social engineering is that defense requires a comprehensive, multi-layered approach. This includes:

• Education and Awareness: Ensuring all personnel understand social engineering threats and how to respond
• Technical Controls: Implementing appropriate technology solutions to support human decision-making
• Policies and Procedures: Establishing clear guidelines for handling potentially suspicious activities
• Culture and Leadership: Creating an organizational culture that prioritizes security and supports employee vigilance
• Continuous Improvement: Regularly testing, measuring, and improving social engineering defenses

Remember, social engineering attacks succeed because they exploit fundamental human nature. The solution isn’t to eliminate human involvement in security decisions—that’s neither possible nor desirable. Instead, the solution is to understand human psychology, account for human limitations, and design security systems that work with human nature rather than against it.

By thoroughly understanding what is social engineering and implementing comprehensive defense strategies, organizations can significantly reduce their risk while maintaining the human elements that make businesses successful. The investment in social engineering defense pays dividends not only in reduced security incidents but also in improved employee confidence, customer trust, and overall business resilience.

As social engineering continues to evolve, so too must our defenses. The organizations that understand what is social engineering and take proactive steps to address it will be best positioned to thrive in an increasingly complex threat landscape. The human element will always be central to cybersecurity—the question is whether it serves as a vulnerability to be exploited or a strength to be leveraged in defense of our digital assets and privacy.
