Social engineering attacks manipulate people into sharing sensitive information or granting access to systems they usually wouldn’t. Often called “human hacking,” this tactic preys on human error - something far harder to detect than weak systems or networks.
Because bad actors rely less on obvious methods like forced intrusion or breaking through firewalls, social engineering is steadily becoming the leading cause of security breaches.
Let’s explore social engineering, the different types of attacks, and best practices to help protect your organization.
Social engineering poses a serious threat to your organization by exploiting human vulnerabilities to bypass even the strongest technical defenses. Bad actors use deceptive tactics to trick individuals into making security mistakes, ultimately gaining access to internal systems where significant damage can occur.
At its core, social engineering exploits human psychology. Attackers prey on emotions—fear, trust, curiosity, or urgency—to influence victims into acting against their best interests. Unlike traditional cyberattacks that rely on breaching systems, social engineering targets human decision-making, making it far more unpredictable and harder to detect.
While there’s no fixed formula for executing these attacks, bad actors commonly rely on these psychological tactics:
People tend to focus on urgent tasks over important ones, and attackers know how to take advantage of that. They create situations that feel urgent, forcing quick decisions without much thought. For example, a pop-up on an employee’s computer might claim their system is compromised and tell them to download a “fix” immediately. Or they might send a fake email saying a vendor account will be locked unless verified immediately. Even something as simple as a flash sale offering 50% off software can trick someone into clicking a malicious link.
People naturally trust authoritative institutions such as government agencies, banks, or tax authorities. A convincing email from what appears to be a bank might request account verification, or a fake message from a government agency might warn of legal action if there is no response. This manipulation of authority can easily coerce victims into sharing sensitive information.
Familiarity breeds trust, and attackers know this. If an employee recently purchased a pair of Nike shoes and receives an email that looks like it’s from Nike asking for feedback, they’re more likely to engage without questioning its authenticity. Fraudsters often mimic well-known brands, using logos, email templates, and fake websites to appear legitimate.
Beyond urgency and authority, attackers often trigger curiosity or fear to provoke action. A vague email with a subject line like “Important update on your account” or “Confidential information about you” can prompt victims to click without hesitation. Similarly, threats of account suspension, data leaks, or financial penalties can drive impulsive decisions.
Social proof influences people's behavior, especially when they observe others taking specific actions. Attackers exploit this by crafting messages that seem to come from a colleague or friend. For example, receiving a file-sharing link from what appears to be a coworker increases the likelihood of clicking it without verifying its authenticity.
Social engineering attacks typically unfold in a series of calculated steps, allowing attackers to manipulate their targets effectively. These attacks are rarely random; instead, they are carefully planned to exploit specific vulnerabilities in employee behavior and organizational security.
The first stage involves thorough research. Attackers gather background information on their intended victim, whether an individual or an organization. This may include job roles, organizational structure, recent transactions, or social media activity. The goal is to identify potential points of entry and uncover weak security protocols that can be exploited.
Once enough information is collected, the attacker establishes contact and gains the victim’s trust. This engagement often feels natural and unthreatening. It could be a phone call from someone posing as IT support, an email from what appears to be a trusted brand or even a friendly message on social media.
After gaining trust, the attacker introduces a stimulus to prompt action. This could be creating a false sense of urgency, invoking authority, or appealing to curiosity. The victim may be tricked into clicking a malicious link, downloading a harmful attachment, or sharing sensitive credentials.
Once the attacker successfully bypasses security through manipulation, they proceed with the final stage of the attack. This could involve installing malware, accessing confidential systems, or moving laterally within the network to escalate privileges and inflict greater damage.
In some cases, the attacker could take additional steps to erase evidence of their intrusion or establish persistent access. This could involve deleting logs, installing backdoors, or manipulating system settings to avoid detection and maintain long-term access.
These are the six most common types of social engineering attacks, detailing how they work and why they are effective.
Phishing is still the most common form of social engineering, with attackers sending fraudulent emails or messages impersonating trusted entities to deceive employees. The aim is to manipulate individuals into revealing sensitive information, downloading malicious software, or transferring company assets.
For example, an employee might receive an email that looks like it’s from your organization’s bank, asking them to verify their identity by clicking on a link and entering account credentials. Bulk phishing campaigns often target large groups, using generic messages that create a sense of urgency, like claims of account suspensions or technical issues.
Spear phishing, however, is a more targeted and sophisticated approach. Attackers often gather information about specific individuals within your organization from platforms like LinkedIn, allowing them to craft convincing emails that appear to come from trusted colleagues or leaders.
Vishing (voice phishing) and smishing (SMS phishing) are social engineering tactics that exploit voice calls and text messages to trick victims.
Pretexting is a more calculated form of social engineering where attackers create a fabricated scenario to manipulate victims.
Attackers might pose as HR personnel, IT support staff, or executives, claiming they need confidential information for legitimate reasons. For example, an attacker could impersonate a company executive requesting sensitive employee data or pose as a bank representative asking for account verification.
Pretexting is particularly effective because it relies on building trust. The attacker carefully crafts their identity and scenario to appear credible, making it difficult for victims to recognize the deception.
Baiting lures victims by offering something enticing in exchange for sensitive information or system access. It can take either a physical or digital form.
Baiting preys on human curiosity and greed, making it an effective way to bypass traditional security measures. Once the victim takes the bait, attackers can gain unauthorized access to personal or corporate networks, leading to data breaches or financial loss.
These physical social engineering tactics focus on bypassing security barriers to gain unauthorized access to secure locations.
In a quid pro quo attack, attackers promise a service or benefit in exchange for sensitive information or system access.
A common example is an attacker posing as IT support, calling employees and offering to solve technical issues. The attacker might say, “I can fix this issue for you, but I need your login credentials to proceed.” Eager to resolve the problem, the victim may share their login details, granting the attacker access to internal systems.
Unlike baiting, which offers an attractive item in exchange, quid pro quo attacks promise a helpful service. This tactic preys on people’s willingness to accept assistance, especially when they believe it will solve an immediate problem.
While entirely preventing social engineering attacks may be impossible, you can take proactive steps to limit their occurrence. Below are key considerations for dealing with suspicious communications:
Regular, comprehensive cybersecurity training for employees is critical to reducing human error and preventing breaches. Focus on practical best practices like strong password management, secure Wi-Fi usage, and recognizing phishing attempts. This should be an ongoing initiative, reinforcing the importance of vigilance and encouraging a security-first mindset throughout your organization.
Ensure that all systems, including operating systems and software applications, are consistently updated and patched. Unpatched vulnerabilities remain a key entry point for attackers, making this a foundational aspect of your security strategy.
Incorporate real-time threat intelligence into your organization’s security framework to stay ahead of emerging threats. This proactive approach allows you to adjust security protocols based on the latest intelligence, ensuring you’re not reacting to threats but staying one step ahead. Regular vulnerability assessments and fine-tuning security measures should be a routine part of your strategy.
Implement advanced monitoring systems that provide continuous surveillance of your network, applications, and endpoints. Utilize tools like Endpoint Detection and Response (EDR) to identify and address malicious activity in real time. This enables your security team to quickly respond to potential breaches, reducing the time to contain and mitigate threats.
Enforce multifactor authentication (MFA) for all critical systems and applications. By requiring multiple forms of verification, MFA significantly reduces the chances of unauthorized access and strengthens your defense against credential-based attacks.
Defending against social engineering requires constant vigilance and a proactive security mindset. Social engineering exploits human vulnerabilities, so equipping your teams with the knowledge and tools to recognize and respond to threats is essential.
