[Phi-hiding assumption][1] can be simply stated as (wrt hardness)

> It is difficult to find small factors of $\varphi(m)$ where $m$ is a number whose factorization is unknown and $\varphi$ is Euler's totient function.


Is the hardness due to this assumption comparatively higher than than the hardness of integer factorization?

My intuition says that finding prime factors of $\varphi(m)$ is simpler than finding the prime factors of $m$. So I believe that the hardness of the phi-hiding assumption is at most equal to the hardness of integer factorization.
