Social Engineering

Social engineering is a psychological manipulation technique used by cybercriminals to deceive and exploit individuals, employees, or organizations into revealing sensitive information, performing specific actions, or providing access to secure systems. Unlike traditional hacking methods that involve exploiting technical vulnerabilities, social engineering primarily relies on human interactions and trust to achieve its objectives.
Here’s a description of social engineering:
Social engineering involves exploiting the inherent trust and natural willingness of people to help or provide information. The attacker may use various tactics to manipulate their victims, such as impersonation, deception, psychological manipulation, and playing on emotions like fear or curiosity.

How this attack happens and Types of this attack

Here’s how various social engineering attacks can happen:

  • Phishing:

Attackers send emails, messages, or texts that appear to be from trusted sources (banks, companies, colleagues) and ask recipients to click on a link or download an attachment.

The link leads to a fake website that resembles a legitimate one, prompting the victim to enter their login credentials or other sensitive information.

Alternatively, the attachment may contain malware that infects the victim’s device when opened.

  • Pretexting:

Attackers create a fabricated scenario, such as posing as a coworker or IT technician, to convince the victim to provide sensitive information or perform an action.

They may call the victim and pretend to need certain information for a legitimate-sounding reason.

  • Baiting:

Attackers offer something enticing, such as a free movie download, in exchange for the victim’s login credentials or other information.

The victim downloads a malicious file along with the promised content, leading to malware infection.

  • Quid Pro Quo:

Attackers promise a service, like technical support or an upgrade, in exchange for the victim’s login credentials or other sensitive information.

  • Tailgating/Piggybacking:

Attackers physically follow an authorized person into a secure area, relying on the victim’s willingness to hold the door or allow access.

  • Impersonation:

Attackers pretend to be someone the victim knows and trusts, such as a colleague, manager, or family member.

They may request sensitive information, money, or actions that compromise security.

  • Reverse Social Engineering:

Attackers convince the victim that they need help or support, gaining the victim’s trust.

Once trust is established, the attacker may request access to the victim’s system or information under the guise of providing assistance.

  • Diversion Theft:

Attackers create a distraction to divert the victim’s attention while they steal or access something valuable.

In all these scenarios, attackers exploit human traits like curiosity, trust, empathy, and a desire to help. They often conduct research to gather information about the target, making the attack more convincing. Social engineering attacks can lead to various negative outcomes, including unauthorized access to systems, data breaches, financial losses, and identity theft.
