Superheavy dark matter may show its presence in high-energy neutrino signals detected on Earth. From the latest results of IceCube, we could set the strongest lower bound on the lifetime of dark matter beyond 100 TeV around 1028s. The excess around a PeV is noticed and may be interpreted as the first signal of dark matter even though further confirmation and dedicated searches are invited.
