SPIRIT BEHAVIOURS

Create the future

At VOIS, we prevent all telephone scams that trick consumers into calling premium rate numbers, such as Wangiri fraud.

Challenges and Solutions

Challenges

We wanted to create a detection method to apply prevention measures for all Wangiri fraud activities. In some markets, their reporting methods didn't reflect some fraudulent activities.

Solutions

We proposed two queries to the local team that split high usage and high duration counts by sorting them from the highest. These queries gave us more suspicious destinations compared to traditional reporting.
