Social Engineering Attack: What You Need To Know

Social engineering is a type of cyberattack that instead of software vulnerabilities aims for vulnerabilities in human psychology. It implies various psychological tricks to lure victims into making security mistakes like giving away some sensitive information. And that is what makes social engineering attacks especially dangerous. The mistakes humans make after the psychological pressing are harder to predict or prevent than some cyberattacks.

Threat actors perform social engineering in multiple steps. Initially, they try to find any possible entry points or weak security protocols in order to begin an attack. After completing the first step, threat actors will proceed with things like gaining the trust of a victim. Then, crooks will use the information they lured out to get into the victim’s accounts.

What Kinds Of Social Engineering Attacks Are

Social engineering attacks can be of various kinds and threat actors can use them anywhere where interaction with humans is involved. Below are the most common social engineering attacks you should be aware of in order not to get caught by them easily:

Spear phishing

One of the most common kinds of phishing attacks where threat actors specifically chose their future victim. They do thorough research on their target like job position, characteristics, social media, friends list, etc. They perform all these steps in order to create a highly-convincing malicious email, that will look legit to a specific person. Spear phishing attacks might take months of preparations before launching an actual attack. But they are harder to detect and have much better chances for success if threat actors are skilled enough.

The malicious email will ask its recipient to click a link or open an email attachment. Both of them contain either malware or malicious website, which does not carry any good to the user. In some cases, crooks bait the victim to start mailing, luring out all sensitive info in a direct way.

Pretexting

It may be a phone call, where someone tries to mimic the bank and ask your personal details. At the end of such a call crook will “suddenly” understand that it got a wrong number.

  • Regularly update your antivirus/antimalware software. Make it a habit to regularly check for your antivirus/antimalware updates or set an automatic update if this option is possible. See if the updates has been applied and also run regular scans for possible infections;
  • Be cautious around various offers. If anyone approaches you either via social media or messengers be attentive to what this person offers and who this person might actually be.
    Google the topic of your conversation and the results should give you a hint to what actually you are dealing with;
  • Enable multi-factor authentication. One of the most valuable things threat actors are going for is your credentials. So it will be only wise to enable for your most important accounts the mechanism of multifactor authentication in case your credentials get stolen or leaked;
  • Make it a habit not to open emails or attachments from suspicious sources. Even if you received an email from someone you know, it’s better to cross check and directly ask the person who sent you this email.
    In case you received an email from your service provider check the info on their official website or call the support line.
