Social Engineering Attacks [8 Common Attacks]

Understanding Social Engineering Attacks

This is the art of impersonating as a trusted person, organization or group of people in order to obtain information which is valuable. Over the past years there has been a rise in cases which involve social engineering attacks. Social engineering attacks can be divided into several categories ranking them from the simplest form of social engineering to complex forms.

The COVID-19 pandemic gave the social engineering attackers greener grounds to carry out their social engineering attacks successfully since the lock down forced many of the employees to work from home. Hackers exploited this chance to carry out massive social engineering attacks on their victims. Below are some of the most common type of social engineering attacks.

  • These types of social engineering attacks are very dangerous since they can even compromise the most protected targets.
  • USB drives contain a payload which executes on connecting to a computer.
  • This creates a connection back to the hackers computer and he can now be able to access files stored on the victim’s computer or even move on to compromise the whole network.
