While over the past two decades a largely consistent picture of neutrino oscillations has emerged, a few unexplained anomalies put a serious dent in this framework. After introducing the LSND, MiniBooNE, and reactor anomalies, we will first discuss attempts to explain the latter two within the Standard Model. In the second part of the talk, we will go beyond the Standard Model and we will show that the widely used benchmark model involving an extra, sterile, neutrino flavor cannot account for all the data. We finally introduce decaying sterile neutrinos as a viable alternative.
