If you’ve ever had a scam call from someone impersonating a representative from your bank, IT company, or any organisation, then you’ve probably experienced social engineering. Social engineering is a feature of a huge majority of phishing scams, fake calls and cyber-attacks; but what is it, and how can you avoid falling for it?
What is social engineering?
Social engineering is a psychological technique employed by phishers, scammers and hackers. It’s the idea that you use a victim’s natural emotions and responses against them in order to manipulate them into doing something, or giving you something.
Social engineering will often be used alongside a fake phone call, a phishing email or another kind of cyber-attack by tricking you into downloading a virus, transferring money, communicating personal data or login details, or access to internal systems or even premises.
What are some examples of social engineering?
Social engineering plays on our ability to respond to something in the moment, and to act before we’ve thought something through. In the case of a phishing email, social engineering is often about giving you a reason to be concerned; for example, informing you that you’ve missed a delivery, or someone has access to your bank account. The natural response to this is to act quickly, which is just what the phisher wants.
In regard to voice phishing, or vishing as it is sometimes known, social engineering may be used to convince you that the person on the other end of the phone call is legitimate. This could be done by asking you some security questions, to make you feel like you need to prove your authenticity to the caller. This also shifts the focus away from thinking about the authenticity of the caller themselves.
Using your info against you
One common social engineering technique is for the scammer to use your information to gain your trust. This might be using information found on social media to prove to you that they know your date of birth, or mother’s maiden name. In businesses, this might be using information found on the company website to suggest that they are legitimate, like dropping names of other staff members, or even the office dog.
‘Can you hold the door?’
Tailgating is another common social engineering tactic. This is where a person attempting to access your premises or systems illegitimately follows a staff member into a building or office. An individual might accomplish this by intentionally having their hands full, so that a well-meaning staff member opens the door for them. They might also use something like a high vis jacket to imply to staff that they’re visiting to fix something.
Baiting, sometimes known as a USB drop, is a social engineering technique where a hacker looking to gain access to your systems intentionally drops a USB drive in or around the business. A victim of baiting will pick up the USB drive, and wanting to find out who it belongs to, plugs it into their laptop. However, the USB drive will automatically install malware to the device, allowing the hacker access to a business’ systems.
How can you avoid social engineering?
Social engineering is very difficult to avoid, because of the way that it plays on our natural responses to situations. However, there are precautions that you can take to avoid becoming a victim of these kinds of attacks.
Don’t allow individuals access to premises without ID
Don’t plug unknown drives and devices into your machine
Don’t give information to cold callers - find the number for the business they claim to represent, and ring them back on a different phone
Don’t click links or download attachments in unexpected emails
Social engineering is designed to get you to do something without thinking it through; the way to avoid it is to slow down, and think before you act. This will help keep you, and your company safe.
