Understanding SIM Jacking
SIM jacking is a form of identity theft that allows hackers to gain access to a victim’s personal and financial information. The process typically begins with a hacker gathering information about the target, such as their name, address, and phone number. This information can be obtained through various means, including social engineering tactics, data breaches, or simply by purchasing it from underground markets. Once the hacker has the necessary information, they will contact the victim’s mobile carrier, posing as the account holder, and request that the phone number be transferred to a new SIM card.
The Mechanics of SIM Jacking
The mechanics of SIM jacking are relatively straightforward. A hacker will typically use social engineering tactics to convince the mobile carrier that they are the legitimate account holder. This can be done by providing the carrier with the victim’s personal information, such as their name, address, and social security number. Once the carrier is convinced that the hacker is the legitimate account holder, they will transfer the phone number to a new SIM card, which is usually in the possession of the hacker. This allows the hacker to receive all calls and texts intended for the victim, including sensitive information such as password reset codes and two-factor authentication messages.
Types of SIM Jacking Attacks
There are several types of SIM jacking attacks, each with its own unique characteristics.
