What is social engineering?

Social engineering is a deceptive practice that exploits human psychology rather than technology to gain unauthorized access to information systems. It involves manipulating individuals into revealing sensitive information or performing actions that compromise security protocols.

Unlike traditional hacking methods that rely heavily on exploiting technical weaknesses within a system, social engineering targets the human element, leveraging psychological tactics to deceive and manipulate individuals. Malicious actors often exploit innate human vulnerabilities, such as trust, curiosity, fear, or a desire to help.

By understanding how people think and behave in certain situations, cyber attackers can craft convincing schemes to trick unsuspecting individuals into divulging confidential data or granting unauthorized access.

This highlights the critical importance of incorporating a human-centric approach to cybersecurity, whereby organizations focus on educating and training employees to recognize and thwart social engineering tactics.

How does social engineering work?

Social engineering techniques work by leveraging psychological tactics to deceive individuals into divulging confidential information or granting unauthorized access to secure systems. One common method is phishing, where attackers send fraudulent emails to trick recipients into providing personal data or clicking on malicious links.

Another prevalent social engineering tactic is pretexting, where an attacker creates a fabricated scenario to obtain sensitive information. For example, an individual might receive a phone call from someone posing as a bank representative, requesting account details to 'verify' their identity.

Baiting involves offering something enticing, like a USB drive labelled 'Confidential' left in a public area. When used, the drive installs malware on the victim's device.

Tailgating occurs when an unauthorized person follows an employee into a secure area, taking advantage of courtesy or distraction to gain access.

Types of social engineering

Social engineering encompasses several tactics used by cybercriminals to manipulate individuals and organisations. Some prominent types include phishing, where fraudulent emails are sent to extract sensitive data; pretexting, which involves creating a false pretext to gain information; and baiting, where malicious actors lure victims into a trap.

These tactics prey on human psychology and vulnerabilities, exploiting trust and authority to deceive unsuspecting targets. In vishing attacks, scammers use voice communication to manipulate victims into divulging confidential information.

Shoulder surfing involves peeking over someone's shoulder to steal login credentials or other sensitive data. Tailgating is another method where attackers gain unauthorised access by following someone through a secure entrance.

Recognising red flags like unsolicited requests for personal info and staying vigilant are key to fending off these social engineering schemes.
