What is Spoofing?

Spoofing definition

The word “Spoofing” means an act in which cybercriminals try to deceive a user through a website, phone or email by pretending to be a trusted person or organization and then seeking private information. Spoofing is typically used to obtain personal information such as credit card numbers or other sensitive information, transfer malicious software to a user’s system, or used as a basis for larger and more serious cyber attacks. Spoofing are calculated attacks in which cybercriminals use social engineering strategies that exploit human nature and weaknesses such as fear and ignorance.

How does spoofing work?

The main goal of a fraudster is to make the target user believe that they are a trusted person or organization. In some cases, online fraudsters achieve this by changing one symbol (letter or number) in the name of a well-known company. A user who does not read the name of the page or e-mail address well and does not pay attention to every letter in the name can very easily believe and become a victim of cyber attacks. 

There are many examples of such scams on the Internet and they are most often in a similar form as this: The user receives an email from the email address “Mark.Collins @ paypalll.com” informing the user that the last completed money transaction was not successfully completed due to a new update of the transaction system, and that it is necessary to re-enter credit card information in the hyperlink window. in the mail. The user accesses the site and enters the requested information which is stolen and used for other illegal hacking actions.

Types of spoofing

  • Via phone call – indicates an attempt to obtain the necessary information by telephone calls. For example, when cybercriminals present themselves as representatives of a user’s bank seeking certain information regarding the user’s bank accounts.

  • Via website – this type of spoofing involves changing one symbol in a link to a known page, and then lazing the entire page in the hope that the user will enter their data such as a password into the fraudster’s database for further illegal use.
