Social engineering is a technique used by cybercriminals to deceive individuals into divulging confidential information or performing actions that may be detrimental to their own interests or that of their organization. It is a non-technical method of breaching security, relying on the human element rather than exploiting technical vulnerabilities.
Social engineering can take different forms, such as phishing emails or phone calls, pretexting (fabricating a scenario to gain access to sensitive information), baiting (leaving a tempting item, such as a USB drive, in a public place to entice someone to use it), or tailgating (following an authorized person into a secure area).
The purpose of social engineering is to manipulate individuals into divulging sensitive information, performing actions, or providing access to systems or physical locations that would otherwise be difficult or impossible to obtain through technical means. The information obtained through social engineering can be used for various malicious purposes, such as identity theft, fraud, espionage, or sabotage.
Social engineering attacks can be highly effective because they exploit human weaknesses, such as trust, curiosity, fear, or authority. Social engineers often use sophisticated tactics to create a sense of urgency or legitimacy to their requests, making it challenging for the victim to identify the attack.
The goal of social engineering attacks may vary depending on the attacker's motives and objectives. Some attackers may seek to steal financial or personal data to commit fraud or sell it on the black market. Others may target intellectual property, trade secrets, or confidential business information to gain a competitive advantage or sell it to rival companies. State-sponsored actors may use social engineering to conduct espionage or sabotage operations, while hacktivists may use it to promote their political or ideological agenda.
Advanced social engineering refers to sophisticated and targeted social engineering attacks that use multiple techniques and leverage extensive research and reconnaissance to achieve their objectives. Unlike opportunistic or random attacks, advanced social engineering attacks are carefully planned and tailored to the specific characteristics and vulnerabilities of the target organization or individual.
Advanced social engineering attacks often involve multiple phases, such as information gathering, profiling, pretexting, baiting, and follow-up, and may use a combination of technical and non-technical methods to deceive and manipulate the victim. For example, an attacker may use spear phishing emails that contain personalized and relevant information to increase the likelihood of the victim falling for the scam. They may also use social media, open source intelligence, or social engineering testing to gather intelligence about the target's behavior, preferences, or vulnerabilities.
Advanced social engineering attacks can be very difficult to detect and prevent, as they often use sophisticated and novel techniques that bypass traditional security controls, such as firewalls, antivirus software, or intrusion detection systems. They also rely on the human element, which is harder to secure and control than technology.
There are several types of social engineering attacks, each with its own characteristics, goals, and techniques. Here are some examples:
Dr. Robert Cialdini, a social psychologist, identified six principles of social engineering in his book "Influence: The Psychology of Persuasion." These principles are commonly used in social engineering attacks to influence or manipulate individuals into disclosing sensitive information, performing an action, or making a decision. Here are the six principles:
Understanding these principles can help individuals and organizations recognize and defend against social engineering attacks by being aware of the tactics used by attackers and by being vigilant and skeptical of unsolicited requests or offers.
No, social engineering attacks can happen both online and offline. While many social engineering attacks are conducted online, attackers can also use in-person techniques to gain access to sensitive information or systems. For example, an attacker might pose as a delivery person, a repair technician, or an employee of a company and use that guise to gain physical access to a building or system. Once inside, the attacker can use a variety of tactics, such as impersonation or deception, to trick employees into revealing passwords or other sensitive information.
Social engineering can occur in a variety of contexts and locations, both online and offline. Here are some examples:
It's important for individuals and organizations to be aware of the different contexts and locations in which social engineering attacks can occur and take steps to protect themselves against these attacks.
Defending against social engineering attacks requires a multi-faceted approach that involves technical controls, security policies, and employee training. Here are some strategies and best practices that organizations can implement to defend against social engineering attacks:
Conduct security awareness training: Educate employees about the risks and tactics of social engineering attacks, and teach them how to recognize and respond to suspicious emails, phone calls, or requests. Provide regular training and reinforcement to keep employees up-to-date on the latest threats. Tailor the training program to different roles and job functions, as employees in different roles may have different security responsibilities and risks.
Implement strong authentication and access controls: Require strong passwords and multi-factor authentication to protect against unauthorized access to sensitive systems and data. Implement least privilege access controls to limit access to only those who need it.
Regularly update software and security controls: Keep software and systems up-to-date with the latest security patches and updates, and regularly review and update security controls such as firewalls, intrusion detection/prevention systems, and anti-malware tools.
Monitor for unusual activity: Use security monitoring tools to detect and alert on unusual activity, such as multiple failed login attempts, unusual access patterns, or data exfiltration attempts.
Perform regular security assessments: Conduct regular security assessments, such as penetration testing or social engineering tests, to identify vulnerabilities and weaknesses in security controls and processes.
Establish security policies and procedures: Develop and enforce security policies and procedures, such as incident response plans, data handling policies, and security awareness training requirements.
Verify requests and information: Implement processes to verify the authenticity of requests and information, such as calling back a known number or email address to confirm the request.
Perform background checks: Conduct background checks on employees, contractors, and third-party vendors to ensure that they do not have a history of malicious activity. Establish policies and procedures for onboarding and offboarding employees, contractors, and vendors, and ensure that access to systems and data is granted and revoked in a timely manner.
By following these practical tips and advice, organizations can establish a strong defense against social engineering attacks and protect their systems and data from unauthorized access or theft.

Remember, to prevent social engineering attacks, it is essential to raise awareness, provide security training, and establish policies and procedures that reduce the risk of human error or malicious intent. It is also crucial to verify the identity and legitimacy of any request for information or access, and to maintain a healthy skepticism towards unsolicited messages or unusual requests.
