We live on a plant where more than half of the population now have cell phones. That’s right, according to Statista, there are 4.68B mobile phone users in 2019 out of the 7B+ people populating plant Earth. As a society, we have come to rely on this personal productivity device for everything from simple communication, entertainment, education and business productivity to even personal identification. But what happens, if your mobile phone falls into the wrong hands? This is exactly what happens with the latest in cybercrime, specifically the SIM Swap Scam.
SIM Swap Scam Demystified
Phone numbers for 2FA authentication are as bad as passwords because most of services have much rely on user phone as the de facto user identifier. SIM swapping is fundamentally a type of targeted Account Takeover (ATO) fraud that exposes a specific weakness in the current binary authentication such as 2FA/MFA solutions offered by many solution providers. While One Time Passwords (OTP) 2FA/MFA is believed to increase personal security, in this case, actually is responsible for breaking it. If you aren’t familiar with how the SIM swap Scam works, cybercriminals just need to execute effectively 3 steps and they can take over your accounts:
- Obtain a base level of personal information about the target through phishing or purchase previously stolen information from the Dark Web or disturbingly in some cases, legally obtain it through one of the major data exchange bureaus
- Use that information online or over the phone or even along with a fake ID at a. retail store in order to impersonate the victim to a mobile phone operator and claim their phone was lost or stolen and have them port the victim’s number to a new SIM. NOTE: Once this is accomplished, the victim’s valid phone will be rendered invalid and all SMS and voice messages intended for the victim will now go to the cybercriminal’s version of the victim’s phone.
- The cybercriminal can then create a path between the applicable email associated with an account of interest and leverage the two-factor authentication using the newly issued SIM to wreak havoc on the victim’s finances.
While two-factor authentication is intended to give you a level of assurance that your accounts are only being accessed by yourself, note that they are insufficient. In this case the SMS messages are being used to validate a fraudulent use of your accounts but are defeated simply because the threat actor now virtually holds your phone and identity, hence most likely your emails and then all associated credentials for various services tied to your emails are also comprisable.
