Most people are aware of terms like phishing and malware, but did you know those are a part of a larger scheme called social engineering? This is not a new kind of fraud; in fact, it’s been used for many years to manipulate a wide range of people into giving up important data about themselves or their workplace.

With technology at the forefront of our lives, social engineering has entered a new era. Physical human interaction is not necessarily required anymore. These criminals can gain information through emails, pop-ups, and public Wi-Fi networks, to name a few.

The main objective is to influence, manipulate or trick users into giving up privileged information or access within an organization. They are doing this right under your nose, and if you’re not paying attention you will be made a victim of this as well.

External Threats

With technology at the forefront of most businesses, external threats are becoming the benchmark for social engineers. They can hack into core business processes by manipulating people through technological means. There are so many ways for social engineers to trick people, that it is best to ensure you are well versed in how they work:


First of all, baiting can be done both in-person and online. Physical baiting would be a hacker leaving a thumb drive somewhere at a business, that an employee picks up and plugs it into a computer. It could be curiosity, or simply thinking a co-worker left something behind. However, as soon as the thumb drive gets plugged in, it infects the computer with malware.

The online version of this could be an enticing ad, something to pique interest. Things like “Congrats, you’ve won!” Also, there is scareware, in which users are tricked into thinking their system is infected with malware, with warnings like “Your computer has been infected, click here to start virus protection.” By clicking on it, you unintentionally downloaded malware to your computer. If you understand what you are looking for, you can usually avoid these situations.


This is probably one of the most popular social engineering attacks, which usually comes in the form of an email. Often, they ask the user to change their email or log in to check on a policy violation. Usually, the email will look official and even take you to a site that looks almost identical to the one you may be used to. After that, any information you type in will we transmitted to the hacker, and you just fell for the oldest online hack in the book.

Spear Phishing

Similar to generic phishing, spear phishing is targeted on one specific person, which takes a little more time and research for hackers to pull off. They often tailor their messages based on characteristics, job positions, and contacts belonging to their victims to make their attack less conspicuous. This could be in the form of an email, acting as the IT guy with the same signature and even cc’d to co-workers. It may look legitimate – but as soon as you click the link, you are allowing malware to flood your computer.

Internal Threats

Originally, social engineering took place in a physical setting. A hacker would do some preliminary research on a company structure or focus on behaviors in order to get that initial access into a building, server room or IT space. Once they have a “foot in the door” so to speak, obtaining pertinent data or planting malware becomes that much easier.


Often, they will enter a building without an access pass by simply acting like an employee that left it at home – this technique is known as tailgating. The only credential they need is confidence. This can also include a hacker posing as an IT person so they can gain access to high-security areas. This is far easier than it sounds too. They can find company shirts at your local thrift store, exude confidence and gain access.


Another interesting process that hackers use to con their way into a business is by creating a hostile situation. According to PC World, people avoid those that appear to be mad, upset or angry. So, a hacker can have a fake heated phone call and reduce the likelihood of being stopped or questioned. Human psychology really is a tricky thing, isn’t it?

Public Information

Then of course, the more you know about someone the more likely you are going to gain the information you need from them. This involves everything from scoping out parking lots, to observing the workspace and even dumpster diving. Nothing is safe anymore and your life is not always as secure as you’d like to think. Something as innocent as a bill can be used to harvest more information about a person.


Similar to online phishing, pretexting is a popular fraud tactic for phone calls. Often, they will disguise themselves as an authority such as a bank, tax official or even police. They will probe you with questions that could lead to giving up information that could compromise your identity.

This personal information can be used to find out much more private information. Not only can they get away with your money immediately, but they can also easily steal your identity with pertinent information like social security numbers or banking information.


Social engineering can be prevented by being educated in it. With so many different ways to steal your important data, it’s imperative that individuals and businesses go through some sort of training regarding these issues.

However, on a day to day basis, getting into certain habits can help. First of all, pay attention to your surroundings. Remember that physical social engineering still exists and you don’t want to be the one that causes a data breach. Next, do not open emails or attachments from suspicious sources. Moreover, if a legitimate-looking email seems slightly suspicious, go to the source and find out for sure if they sent it.

Multi-factor authentication can help to curb fraud as well. One of the most valuable pieces of information attackers seek is user credentials. Using multi-factor authentication helps to make sure your account’s protected in the event of system compromise.

Furthermore, if an offer seems too good to be true, it probably is. Don’t click the link – you didn’t win a cruise. Finally, keep your antivirus and/or antimalware software updated at all times. This is the best line of defense if for some reason your system has been compromised. For the most part, use your best judgment and common sense. Social engineers have gotten very good at their jobs, but that’s okay because you’ve gotten very good at yours too and can combat these sneaky hackers.
