Swedish security enthusiast took advantage of weaknesses in Voi scooter app to get $100,000 worth of free rides. The app does not abide by the same security measures implemented in the sign-up process and skips certain verifications that would prevent fraud. The issues he discovered are at API-level and can help add promo codes for free rides from different Voi partners that distribute them, like Revolut, Swedish Railroads, or Bumble dating app. The researcher took down his post explaining how “acquired”” the free credit because the issues are still present and wants to give Voi a chance to fix things up.”
