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 workplace. A prime example of social engineering goes back to Greek mythology with the Trojan horse. They infiltrated the city of Troy with a “peace offering” filled with soldiers, thus winning the war. 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 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.

Baiting

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, then an employee picks it up and plugs it into a computer. Could be curiosity, or simply thinking a co-worker left something behind. However, as soon as the thumb drive gets plugged in, it will infect your 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 deceived to think their system is infected with malware, saying things 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.

Phishing

This is probably one of the most popular social engineering attacks. Fairly generalized, this usually comes in the form of an email. Often, they ask the user to change their email, or login 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 be transmitted to the hacker. You just fell for the oldest online hack in the book.

Spear Phishing

Similar to generic phishing, spear phishing is a more targeted scam. This does take a little more time and research for hackers to pull off, but when they do it’s hard to tell the difference. 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’s to co-workers. It looks 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.

Tailgating

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 and conning people into believing that to be true so they can gain access to high-security areas. This is far easier than it sounds. It may be possible to find company shirts at the local thrift store. That and confidence could gain access for hackers.

Psychology

Another interesting process hackers use to con their way into a business is by creating a hostile situation. According to PC World, people avoid those who appear to be mad, upset or angry. A hacker can fake a 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, 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 information about a person.

Pretexting

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 a whole slew of things. Not only can they get away with your money immediately, they can easily steal your identity with pertinent information like social security numbers or banking information.

Prevention

Social engineering can be prevented by being aware of 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 caused your business corrupted data. 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. Also, multi-factor authentication can curb fraud immensely. One of the most valuable pieces of information attackers seek are user credentials. Using multifactor authentication helps ensure your account’s protection 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. Then finally, keep your antivirus and/or antimalware software updated. 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, and you can combat these sneaky hackers.
