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

It is difficult to findingfind small factors of φ(m)$\varphi(m)$ where m$m$ is a number whose whose factorization is unknown, and φ$\varphi$ 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 φ(m)$\varphi(m)$ is simpler than finding the prime factors of m$m$. So I am believe that the hardness of the phi-hiding assumption is at most equal to the hardness of integer factorization.
