Ford EcoSport 2014 is vulnerable to keyfob replay attack wherein an attacker could just record the keyfob unlock signal and then transmit it again via an RF device like YardStick One, HackRF or Flipper Zero.
In this attack scenario, the researcher was able to capture the keyfob transmission by clicking the unlock button three times and then recorded it using Flipper Zero. Transmitting the three unlock signals would also unlock the vehicle three times.
