Context:

• SIM-swapping is a growing form of identity theft that goes beyond hacking into an email or social media account.
• In today’s digital age, mobile phones are central to our lives, serving as a gateway to personal, financial, and professional realms. However, this convenience also brings vulnerabilities, one of which is SIM swapping.

What is a SIM?

• A subscriber identity module (SIM) is a small chip card that activates calling, texting, and data services in a mobile phone.
• Each SIM card has unique identifiers associated with just one mobile account. Because of these distinctive details, removing a SIM card from one phone and putting it into another automatically transfers that card’s mobile services to the new physical device.

About SIM Swapping

SIM swapping is a sophisticated form of identity theft where cybercriminals manipulate mobile carriers to port a victim’s phone number to a SIM card they control.

Once successful, the attacker receives all calls, messages, and two-factor authentication (2FA) codes meant for the victim. This gives them access to personal information, financial accounts, and other sensitive data.

The FBI Internet Crime Complaint Center reports that SIM-swapping complaints have increased more than 400% from 2018 to 2021, with associated personal losses estimated to be more than $68 million.

The Modus Operandi

• Researching the Victim: The attacker gathers personal information about the target via social engineering, phishing attacks, or data breaches.
• Contacting the Carrier: Armed with the gathered information, the attacker contacts the victim’s mobile carrier and impersonates the victim.
• Convincing the Carrier: The attacker persuades the carrier to change the victim’s phone number to a new SIM card by providing convincing but fraudulent information.
• Taking Control: Once the swap is successful, the attacker receives all incoming calls and messages, including 2FA codes, facilitating unauthorized access to the victim’s accounts.
