In our highly interconnected world, technology has become a fundamental aspect of both our personal and professional lives. This increased integration has not only broadened the scope and frequency of threats, encompassing both technical and human vulnerabilities but has also given rise to a new level of sophistication among cyber criminals. These malicious actors excel at exploiting the most vulnerable element in any security system: humans. The art of manipulating individuals for illicit purposes is commonly referred to as social engineering. There are several types of social engineering attacks, each exploiting different aspects of human psychology. Read on to learn more about the various social engineering tactics employed by cybercriminals and gain crucial insights to safeguard yourself and your organization from falling victim to these deceptive schemes.

1. Phishing Attacks
One of the most prevalent forms of social engineering, phishing, attempts to gain access to your system via email, text messages, instant messages, or websites that appear to be from a legitimate source. Most of the time attacks will impersonate reputable organizations or individuals to trick victims into sharing sensitive information such as passwords, credit card numbers, or personal data. To protect yourself:
- Be wary of unsolicited messages, emails, or calls from unknown or unexpected sources, especially those that ask for sensitive information.
- Verify the authenticity of the sender by double-checking email addresses or contacting the organization directly.
- Hover over links before clicking to ensure they are safe and legitimate URLs.
- Attain and regularly update a reputable security software to detect and block phishing attempts.
- Avoid clicking on links or downloading attachments unless you can verify the sender's legitimacy.
- Be alert to common phishing email red flags, such as generic greetings, spelling and grammatical errors, or urgent or threatening language.
- Enable 2FA whenever possible. Even if your password is compromised, having an additional layer of authentication adds an extra barrier against unauthorized access.
- Be cautious on social media. Avoid clicking on links or accepting friend requests from unknown or suspicious profiles.
- Report suspected phishing attempts to your email provider and the Anti-Phishing Working Group (reportphishing@apwg.org).
2. Pretexting
Pretexting is the clever fabrication of a scenario where an attacker assumes a false identity to manipulate victims into divulging confidential information or performing actions they wouldn’t otherwise do. These attacks often exploit trust, authority, or sympathy to gain victims’ compliance. You can protect yourself by:
- Always validate the identity of the person requesting information, even if they ‘seem’ trustworthy.
- Implement strict protocols for sharing sensitive data, especially over the phone. Ask probing questions to understand the purpose behind the request.
- Regularly train employees on identifying and reporting suspicious requests. Establish protocols for verifying identities before releasing sensitive information.
- Limit the amount of personal information publicly available to minimize attacker’s available ammunition.
3. Baiting
Baiting focuses on enticing victims with something desirable, such as free software, media, or other tempting offers, to lure them into taking compromising actions. This can involve clicking on malicious links, downloading infected files, or inserting compromised devices into your system. To safeguard against baiting:
- Avoid downloading files or software from sketchy/untrustworthy sites.
- Use caution when plugging external devices into your systemand avoid the temptation to pick up or use unattended and unfamiliar media devices.
- Educate yourself and employees about the risks associated with seemingly harmless ‘freebies’.
- Regularly update your antivirus softwareand employ endpoint monitoring security solutions that can detect and prevent the use of malicious devices. Consider using encrypted external storage devices.
4. Tailgating
Tailgating, or piggybacking, is when an attacker gains physical access to a restricted area by following an authorized person or by convincing them to hold the doors open. To prevent unauthorized access:
- Put into place strict physical security measures, such as access control and security cameras.
- Encourage employees to report suspicious individuals or activity.
- Educate employees on the importance of not sharing access credentials.
- Regularly assess and update your physical security protocols.
- Install surveillance cameras at entry points to monitor and record the movement of individuals. This not only deters tailgating but also provides evidence in case of a security incident.
- Implement a visitor management system that requires all visitors to sign in and obtain proper identification.
5. Impersonation
Impersonation is when an attacker is posing as a trusted individual, such as a co-worker, service technician, or a customer support representative. Impersonation aims to manipulate victims into disclosing sensitive information or granting unauthorized access. Protect yourself by:
- Verifying the identity of the person through appropriate channels.
- Create clear communication protocols within your organization to validate requests.
- Implement multi-factor authentication for sensitive accounts and systems.
- Conduct regular security awareness training for employees emphasizing the importance of verifying identities before sharing sensitive information.
- Secure communication channels and be skeptical of unsolicited communications.
6. Quizzes and Surveys
Attackers may create seemingly harmless quizzes or surveys to collect information about individuals, which can later be used for malicious purposes.
- Never complete social media quizzes or surveys that ask for personal details such as birthday, mother's maiden name, hometown, and favorite pet, which are commonly used in security questions.
- Be skeptical about unknown quizzes from unfamiliar or untrusted sources. Verify the legitimacy of the website and platforms and review privacy policies to ensure that you understand how your data will be used, stored, and shared.
- Consider using a secondary or disposable email address.
- Be wary of clickbait, such as promises of unbelievable prizes or sensational claims.
7. Watering Hole Attacks
Attackers compromise websites or group forums that their target frequently visits, anticipating that the target will unknowingly download malicious content. By infecting the website with malware, the attacker can exploit vulnerabilities in the visitor’s system.
- Regularly update your operating system, web browser, and all software installed on your computer.
- Choose a browser that prioritizes security features and that automatically updates to the latest version.
- Consider using a VPN, especially when accessing websites that may have a higher risk of being compromised. A VPN encrypts your internet connection, making it more difficult for attackers to monitor your activities.
- Employ network security measures, such as firewalls and intrusion detection systems, to monitor and filter network traffic.
- Use ad and script blockers to protect your network. Advertisements on compromised websites can sometimes be vectors for attacks.
As technology continues to become more a part of our lives, social engineering continues to pose a significant threat. By understanding the various types of social engineering tactics and implementing proactive measures, both individuals and organizations can strengthen their defenses. Vigilance, healthy skepticism, and ongoing education are crucial to safeguarding your valuable data and protecting yourself from falling victim to these cyber schemes.
