In this work, we consider a tactical hybrid network where a military adhoc network utilizes a commercial cellular network as backbone for data traffic. It is assumed that all traffic goes through a cache at the cellular base station with Least-Recently Used (LRU) policy. We study the possibility of inferring the military traffic rate from cache hit/miss observations of a single adversary node. We show the possibility of such an inference by presenting algorithms for estimating the parameters of
