As it turns out, they're not really hiding anything, just like that not related to security. It all has a very simple explanation. Flight attendants must count all passengers on the plane before takeoff, so as not to make a mistake during counting, they use clicker counter, a mechanical counting device that ensures that they are not lost during counting.
They hide their hands behind their backs so as not to attract too much attention with this act. Sometimes passengers are counted twice, the first time upon boarding and the second time when everyone is seated. Pay attention the next time you fly, because you might notice a clicker in their palm.
