Social engineering tactics
As you might recall, social engineering is a manipulation technique that exploits human error to gain private information, access, or valuables. It's an umbrella term that can apply to a broad range of attacks. Each technique is designed to capitalize on the trusting nature of people and their willingness to help. In this reading, you will learn about specific social engineering tactics to watch out for. You’ll also learn ways that organizations counter these threats.

One of the highest-profile social engineering attacks that occurred in recent years was the Twitter Hack of 2020. During that incident, a group of hackers made phone calls to Twitter employees pretending to be from the IT department. Using this basic scam, the group managed to gain access to the organization’s network and internal tools. This allowed them to take over the accounts of high-profile users, including politicians, celebrities, and entrepreneurs.
Attacks like this are just one example of the chaos threat actors can create using basic social engineering techniques. These attacks present serious risks because they don’t require sophisticated computer skills to perform. Defending against them requires a multi-layered approach that combines technological controls with user awareness.
Signs of an attack
Oftentimes, people are unable to tell that an attack is happening until it's too late. Social engineering is such a dangerous threat because it typically allows attackers to bypass technological defences that are in their way. Although these threats are difficult to prevent, recognizing the signs of social engineering is a key to reducing the likelihood of a successful attack.
These are common types of social engineering to watch out for:
Attackers might use any of these techniques to gain unauthorized access to an organization. Everyone is vulnerable to them, from entry-level employees to senior executives. However, you can reduce the risks of social engineering attacks at any business by teaching others what to expect.
Encouraging caution
Spreading awareness usually starts with comprehensive security training. When it comes to social engineering, there are three main areas to focus on when teaching others:
-
Stay alert of suspicious communications and unknown people, especially when it comes to email. For example, look out for spelling errors and double-check the sender's name and email address.
-
Be cautious about sharing information, especially over social media. Threat actors often search these platforms for any information they can use to their advantage.
-
Control curiosity when something seems too good to be true. This can include wanting to click on attachments or links in emails and advertisements.
Pro tip: Implementing technologies like firewalls, multi-factor authentication (MFA), block lists, email filtering, and others helps layers the defenses should someone make a mistake.
Ideally, security training extends beyond employees. Educating customers about social engineering threats is also a key to mitigating these threats. And security analysts play an important part in promoting safe practices. For example, a big part of an analyst's job is testing systems and documenting best practices for others at an organization to follow.
Key takeaways
People’s willingness to help one another and their trusting nature is what makes social engineering such an appealing tactic for criminals. It just takes one act of kindness or a momentary lapse in judgment for an attack to work. Criminals go to great lengths to make their attacks difficult to detect. They rely on a variety of manipulation techniques to trick their targets into granting them access. For that reason, implementing effective controls and recognizing the signs of an attack go a long way towards preventing threats.
