Social engineering, a cunning technique used by cyber criminals, exploits human psychology to gain unauthorised access to sensitive information or systems. By manipulating individuals, attackers can bypass technical security measures and wreak havoc on local businesses.
This article delves into the various types of social engineering attacks, real-world examples, and effective strategies to protect your business, customers and employees.
Types of Social Engineering Attacks
Phishing
Phishing is one of the most common social engineering tactics, involving deceptive emails or messages that trick recipients into revealing personal information or downloading malicious software. Attackers often impersonate legitimate organizations to lure unsuspecting victims. For instance, a phishing email might claim to be from a bank, urging the recipient to update their account details by clicking on a malicious link.
Vishing (Voice Phishing)
Vishing leverages voice communication, typically phone calls, to deceive individuals into divulging sensitive information. Attackers may pose as bank representatives, IT support personnel, or government officials to gain trust and extract valuable data.
Pretexting
Pretexting involves creating a convincing scenario or story to manipulate individuals into providing confidential information. Attackers may fabricate elaborate tales to gain access to restricted areas or sensitive systems. For example, a pretexting attack might involve an attacker posing as a new employee who needs assistance with their computer setup.
Baiting
Baiting involves enticing victims with physical objects, such as infected USB drives or external hard drives, to compromise their systems. Attackers may leave these devices in public places or send them to targeted individuals, often disguised as legitimate items.
Quid Pro Quo
Quid pro quo attacks exploit the human tendency to help others. Attackers may offer assistance or favors in exchange for sensitive information or access privileges. For example, an attacker might offer to help a colleague with a task in exchange for their password.
Tailgating/Piggybacking
Tailgating or piggybacking involves following authorized individuals into secure areas without proper authorization. Attackers may use social engineering techniques, such as feigning a sense of urgency or familiarity, to bypass security checkpoints.
Watering Hole Attacks
Watering hole attacks target specific groups of individuals by compromising websites or online platforms they frequently visit. Attackers infect these websites with malicious code, which is then executed when victims access the compromised site.
Real-World Social Engineering Examples
- Phishing: The 2016 phishing attack on Yahoo compromised the accounts of over 500 million users.
- Vishing: In 2018, a vishing scam targeted businesses, leading to significant financial losses.
- Pretexting: A high-profile pretexting attack in the early 2000s compromised the personal information of celebrities and politicians.
- Baiting: In 2019, a USB drive infected with malware was left in a parking lot, leading to a data breach at a major corporation.
- Quid Pro Quo: A recent study revealed that many employees are willing to share sensitive information in exchange for favors or promotions.
- Tailgating/Piggybacking: A 2020 survey found that a significant number of employees allow unauthorised individuals to enter secure areas.
- Watering Hole Attacks: In 2013, a watering hole attack targeted journalists and human rights activists, compromising their devices.

- Enforce strict access controls and physical security measures.
Incident Response
- Establish a comprehensive incident response plan to handle social engineering attacks effectively.
- Conduct thorough investigations to identify the root cause of attacks and prevent future incidents.
Testing and Assessment
- Regularly conduct vulnerability assessments and penetration testing to identify weaknesses in your security posture.
- Simulate social engineering attacks to evaluate employee awareness and response.
Frequently Asked Questions
What are the most common social engineering tactics?
Phishing and vishing are two of the most common social engineering tactics. Phishing involves sending deceptive emails or messages that trick recipients into revealing personal information or downloading malicious software. Vishing, on the other hand, leverages voice communication, typically phone calls, to deceive individuals into divulging sensitive information.
How can I protect myself from social engineering attacks?

Enable two-factor authentication: This adds an extra layer of security to your accounts.
Stay informed: Keep up-to-date on the latest social engineering tactics and scams.
What are the warning signs of a social engineering attack?
Some common warning signs of a social engineering attack include:
Urgent requests: Attackers often create a sense of urgency to pressure victims into making hasty decisions.
Unexpected requests for sensitive data: Legitimate organizations will rarely ask for sensitive information via email or phone.
Suspicious emails or phone calls: Be wary of emails or calls with poor grammar, spelling errors, or suspicious sender addresses.
Requests to bypass security procedures: Legitimate businesses and vendors will never ask you to reveal passwords or try to bypass established security procedures.
What should I do if I think I’ve been targeted by a social engineering attack?
If you believe you’ve been targeted by a social engineering attack, it’s important to take immediate action. Report the incident to your IT department or security team. They can help you assess the situation and take steps to mitigate any potential damage.
How can businesses prevent social engineering attacks?
Businesses can prevent social engineering attacks by implementing a combination of technical controls, employee training, and security policies.
Regular employee training: Conduct regular security awareness training to educate employees about social engineering tactics and best practices. Maybe offer an incentive or monthly prize draw.
Implement Technical controls: Use strong password policies, multi-factor authentication, and robust email filtering and spam protection solutions.
Policy implementation: Develop clear security policies and procedures to guide employee behavior.
Incident response: Establish a comprehensive incident response plan to handle social engineering attacks effectively.
Testing and assessment: Regularly conduct vulnerability assessments and penetration testing to identify weaknesses in your security posture.
