Definition, Detection and Prevention of Social Engineering

By | 2023-08-01

Cyber attackers often use social engineering attacks because they can be highly effective at circumventing security measures. Here are a few reasons why they are commonly used:

Exploitation of human trust

Social engineering relies heavily on manipulating human emotions, trust, and curiosity. Cyber attackers often find it easier to exploit a person’s natural inclination to trust than to discover ways to hack their software.

Bypassing advanced security measures

Even the most secure system can be vulnerable to social engineering attacks. While technology has been continually evolving to resist various forms of attacks, humans remain susceptible to manipulation and trickery.

Ease and cost-effectiveness

Compared to other methods like brute force attacks or hacking through complex encryption, social engineering can be a more straightforward and cost-effective method. It often requires less technical skill and resources to execute a social engineering attack successfully.

Hard to detect and prevent

Social engineering attacks can be hard to detect because they don’t necessarily involve unusual network activity that can be flagged by security systems. Also, the effectiveness of these attacks makes them particularly difficult to prevent.

Increased chances of success

People often are the weakest link in the security chain. Even if a system has the best technical safeguards in place, it’s often easier to trick someone into giving up their password than it is to crack the password through brute force or sophisticated hacking techniques.

Versatility of methods

Social engineering attacks can come in many forms – phishing emails, pretexting, baiting, quid pro quo, etc., allowing the attackers to choose a method depending on the target’s perceived vulnerabilities.

By training employees about the risks and symptoms of social engineering attacks, organizations can better protect themselves from these types of threats. This includes education about phishing emails, the risks of sharing information with unknown parties, and the importance of using strong, unique passwords.

What is Social Engineering?

Social engineering is a tactic used by cybercriminals that involves manipulating individuals into revealing confidential information, such as passwords, credit card numbers, or even security clearances. This is typically done by creating a sense of trust, urgency, or fear in the victim, leading them to break standard security practices.

The term “social engineering” is used because these types of attacks exploit the social interactions and behaviors of people rather than the technical aspects of computer systems or networks.

Social engineering attacks can take many forms, including:

  • Phishing: This is probably the most common type of social engineering attack. It typically involves sending emails that appear to come from trusted sources, but actually contain malicious links or attachments.
  • Spear Phishing: This is a more targeted form of phishing where the attacker has researched their victim and customized their attack to increase their chances of success.
  • Pretexting: This involves creating a false scenario (or pretext) to engage the victim. For example, the attacker might impersonate a co-worker or a personal contact, tricking the victim into providing confidential information.
  • Baiting: This technique involves offering something attractive to the victim (like free software) in exchange for private data. The “bait” usually contains malware that then infects the victim’s computer.
  • Quid Pro Quo: Similar to baiting, quid pro quo involves offering a service or benefit in exchange for information. For example, an attacker might impersonate a technical support specialist who offers to solve a non-existent problem in exchange for the victim’s login credentials.
  • Tailgating: In this method, an unauthorized person physically follows a legitimate person into a restricted area. This type of attack often relies on the natural inclination of people to hold doors open for others.

In all of these types of social engineering, the goal is to trick the victim into breaking normal security procedures, allowing the attacker to gain access to systems or information.

How can Social Engineering be prevented?

Preventing social engineering attacks largely involves being aware of the tactics used by cybercriminals and promoting a culture of security within your organization. Here are some steps you can take:

Educate Yourself and Your Team

Make sure everyone in your organization is aware of the different forms of social engineering attacks and how they work. Regular training sessions can help keep this knowledge fresh and top of mind.

Think Before You Click

Be cautious with emails containing links or attachments, especially from unknown senders. Confirm the email is from who it says it’s from by checking the email address carefully. When in doubt, don’t click.

Verify Requests

If you receive a request for sensitive information, always verify it before responding, especially if it’s an unsolicited request. This can often be done with a quick phone call.

Be Wary of Unsolicited Help

Be suspicious of unsolicited contact from individuals offering to fix a problem with your computer or network. These could be attackers attempting a quid pro quo attack.

Secure Your Information

Limit the amount of personal information you share online. Social engineers often gather publicly available information for their attacks.

Implement Multi-Factor Authentication (MFA)

By using multiple factors of authentication, you can greatly reduce the chance of an attacker gaining access to your systems.

Use Strong, Unique Passwords

Don’t use the same password for multiple accounts, and make sure your passwords are complex and not easily guessed.

Keep Software Up-to-date

Ensure that all of your systems, software, and applications are up-to-date. Many updates contain security patches that fix known vulnerabilities that social engineers could exploit.

Implement a Clear Policy

Make sure your organization has a clear policy for handling sensitive information and that employees know what they are allowed to disclose and to whom.

Regularly Backup Data

Regular backups can help mitigate the damage if a social engineer does manage to compromise your systems.

Remember, the key to preventing social engineering is vigilance and education. The more you and your team know about the tactics used by attackers, the better you’ll be able to protect yourselves.
