We analize the properties of a Kerr-like wormhole supported by phantom matter, which is an exact solution of the Einstein-phantom field equations with two parameters: mass and scalar field charge. The solution has a naked ring singularity which is unreachable to null geodesics falling freely from outside. Similarly to Roger Penrose's cosmic censorship, here we show that a naked singularity can be fully protected by the intrinsic properties of the wormhole's spacetime.
