How to Prevent Social Engineering Attacks?

Don't fall for the latest scareware and spamware and scam tactics. Understand how to prevent social engineering attacks, what goes into them, and take steps to engage and quarantine threats.

Social engineering attacks are becoming more common in cyber security. They are more effective than traditional malware campaigns because they exploit human psychology. The hacker can persuade the victim to do what they want, which means they can get users to act beyond their normal responses. Unlike other cyber attacks, where there’s a typical pattern or modus operandi, social engineering can be unpredictable because it takes advantage of the multiple layers of human emotions.

In this guide, we will explain how social engineering attacks work. You will learn how to prevent social engineering attacks and take steps to address them.

What are Social Engineering Attacks?

Social engineering attacks make people emotionally charged and react like they usually wouldn’t. The attacker will probe your sentiments; a moment of weakness is needed to leak your sensitive details. Social engineering attacks are dangerous because you don’t know what to expect. Anyone can react negatively or destructively when put in those corners or mental spaces.

There are various types of social engineering attacks. To learn how to prevent social engineering attacks, you should be aware of them. They are as follows:

• Baiting occurs when the attacker installs malware on a physical device, such as a USB flash drive, and places it in an easily accessible location. The victim then finds the device, picks it up, and inserts it into the computer, unintentionally installing the malware.
• Phishing is when the attacker sends a fraudulent email disguised as a legitimate email that appears to come from a trusted source. The message tricks the victim into giving sensitive information and clicking on any malicious links or attachments embedded inside it.
• Spear phishing is a more sophisticated and targeted form of phishing. It involves an email specifically crafted for someone higher up in the organization. The attacker will spend months or weeks conducting reconnaissance and researching the victim, targeting them only when the opportunity is right.
• Vishing is a social engineering attack that involves voice communications. The attacker calls you over the phone and asks questions to verify your identity. When you engage with them or give out sensitive details, they can extract information about you and the target. This is one of the most common social engineering attacks, and most people fall for it.
• Scareware – A type of social engineering attack that tricks the victim into thinking that their system has been infected with malware and they inadvertently download illegal content. The attacker will offer them a solution, such as a tool to get rid of that malware, and the user is tricked into downloading and using that tool.
• Watering hole – A sophisticated social engineering attack where the attacker will try to compromise users by infecting websites they frequently visit, gaining network access and their trust in the process.
• Honey trap: The social engineer pretends to be attractive and interacts with a person online. They might attempt to fake an online relationship and gain sensitive information.
• Quid pro quo – The most straightforward way to explain how this social engineering attack works is this: A company has a technical issue, and your company has a serial number. The attacker will call you up, reference that serial number, and you will be convinced as the victim. They will say that you have a technical issue, and you will believe it because it is true.

How Do Social Engineering Attacks Work?

Social engineering attacks work on the premise of taking advantage of your emotions, naivety, and gullibility. It tricks users by using psychological manipulation and persuades them to make security mistakes unknowingly.

Victims may accidentally leak or give away sensitive information or be influenced by the perpetrators.

Their personal and financial information gets stolen by them before they realize it’s too late to do anything about it. A social engineering attack may also set a trap for victims and play mind games on them.

The adversary’s goal is to gain their trust and lower their guard. Then, they will take advantage of this. They will motivate them to take unsafe actions outside their jurisdiction, such as clicking on web links or opening attachments that are deemed malicious. In some cases, they might even impersonate officials.

The victim will not be aware of what’s going on and will unknowingly cooperate with the adversary. If they visit any website presented by them or enter their details on any login pages, the perpetrator can take over their device or network entirely.

One of the biggest dangers of social media is that it can be used as a means of communication between people. Social engineering attacks don’t work against everyone.

But a single victim is enough to trigger a massive attack that can damage the organization. Social engineering attacks can involve phishing emails, fake websites, transaction interceptions, identity theft, or other methods. They are not predictable and can work or go beyond the norm of traditional cyberattacks, which is one reason they go undetected.

How to Detect Social Engineering Attacks?

A social engineering attack that can happen from inside your organization can be the result of an insider attack. So assess your workplace sentiments and see how your coworkers are behaving. If there are no negative vibes and everyone is on the same page, then that’s usually a good sign.

You should be concerned if there is a lot of discord in the workplace community. A grudge today can escalate into a sophisticated social engineering threat in the future, and that’s important to remember.

When it comes to social engineering attacks launched from outside your organization, especially in the case of phishing mails, be wary of any messages that warrant your immediate attention, if any emails invoke a sense of urgency, scare tactics, or tell you to click on malicious links too quickly to reactivate your account, transfer funds, or explicit taxes, avoid them.

Best Practices to Prevent Social Engineering Attacks

Here are 10 approaches on how to prevent social engineering attacks:

• Look for the padlock icon in a website’s URL. Check to see if the URL begins with the HTTPS or HTTP prefix. The website is secure and can be accessed if it has an HTTPS prefix. However, if it has an HTTP prefix, you should avoid it. Also, check for the website’s SSL certification and other security protocols.
• Enable multi-factor authentication for all accounts in your organization.  Conduct regular cloud audits and check for inactive and dormant accounts so that they are not misused by insiders or outsiders when employees exit or enter the organization. Install anti-virus solutions, anti-malware software, and web firewalls.
• Use more than one password to log into multiple accounts. Don’t use the same password everywhere, and rotate your passwords often.
• Employ active AI threat detection technologies and security scanning solutions. Scanning your endpoints, user accounts, networks, and IoT devices can give you clues into whether a social engineering attack will happen sooner or later.
• If deviations are from traditional activity patterns, you know something is in the works. For example, suppose an employee logs in at unsuspecting hours or suddenly has spikes in their downloads on a given day. In that case, they could be collecting intelligence, doing recon, or preparing for a social engineering attack. These two measures apply specifically to insider threat-based social engineering attacks.
• Do regular security audits and vulnerability scans to close gaps in your infrastructure and seal blind spots.
• Install firewalls, antivirus and anti-malware solutions, and phishing detection software. Use tools like SentinelOne to enable offensive security and stay multiple steps ahead of your adversaries.
• Verify the sender of the email address before you engage with them or interact. Check the domain name and look for inconsistencies in the email body like grammatical, layout, structural, or formatting errors.
• If you receive voice calls from unknown entities claiming to be authorized officials, verify their identity before you disclose personal information. Remember that social engineering activists collect a lot of intelligence about the organization and the people who work for it.

Real-World Examples of Social Engineering Attacks

Here are some real-world examples of social engineering attacks:

• Insight Partners was affected by a social engineering attack. The private equity firm said it would take several weeks to recover or pinpoint the scope of the damage. Stakeholders were notified, and everyone was encouraged to be vigilant and tighten their security protocols. Insight has a significant cybersecurity footprint, and since September 30, 2024, it has had more than $90 billion in regulatory assets under management.
• In the healthcare sector, a hacker group named Scattered Spider had launched social engineering tactics and tools. The attack was financially motivated and used AI to spoof the voices of victims. They ended up gaining access to their records. And the attacks called IT help desks and asked them to correctly answer security questions by taking advantage of the stolen information. Scattered Spider bypassed popular endpoint security tools and even deployed ransomware.

Conclusion

There’s no one-size-fits-all solution when it comes to combating social engineering attacks. The first step to eliminating them is learning how to prevent social engineering attacks. Once you understand how they work, what goes on behind them, and what attackers are thinking, you can predict where they are coming from and take the necessary measures to secure yourself.

The key thing is always to never trust, but verify. Build a zero-trust network security architecture and implement the principle of least-privileged access across all your accounts. Don’t give unlimited access to anyone and restrict access rights. Having strong access controls and teaching your employees about the best cybersecurity practices will also help. Make sure they know about the latest social engineering attacks so that they are not taken by surprise.
