Carousell will then send a verification SMS to the mobile number with a one-time code. The service will supply you with a mobile number that you can use to fill the mobile number field in the account creation process.ĥ. For the mobile number field, request a mobile number in. For this scenario, the project is Carousell.ģ. Project is the online service or platform they support and are capable of intercepting SMS verification. First, you need to sign up for a account and top up their balance.Ģ. To demonstrate how SMS PVA and Android SMS interception work together, we’ve created a hypothetical scenario using Carousell-Southeast Asia’s biggest open market.ġ. This means that the users of SMS PVA services typically use them in combination with some sort of residential proxy or a VPN service that allows them to select the country of the IP exit node to match the telephone number used to register the service. We observed that the user registration requests, and SMS PVA API requests often come from an exit node of a VPN service or a residential proxy system. Using Trend Micro™ Smart Protection Network™ (SPN) telemetry, we have identified that the users of SMS PVA services extensively use a variety of proxy services and distributed VPN platforms to bypass the IP geolocation verification check. To circumvent this, SMS PVA users use third-party IP masking services, such as proxies or virtual private networks (VPNs), to change the IP address that will be recorded when they try to connect to a desired service.

For example, certain content can be made only available to specific countries. Similarly, location-specific validation or restriction can be required. For example, an IP address may be required to match the geographical location of a phone number before a user can create an account. Many services use additional verification during the registration of new accounts. We’ll also illustrate an example of how users can use to get an SMS verification code without using their own mobile number. In this article, we’ll discuss how and Android SMS interception works hand in hand. Customers simply need to sign up to their customer-facing portal,, to start using their services. ReceiveCode offers users access to SMS code verification sent to mobile numbers that the company has in their storage. In part one, we extensively discussed SMS PVA and started investigating a particular service called ReceiveCode that our team first found on a Facebook advertisement.
