The results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20/fb of proton-proton collision data at 8 TeV, recorded with the ATLAS detector at the LHC, are reported. The top squark is assumed to decay via stop -> top+LSP where LSP denotes the lightest neutralino in supersymmetric models. The search targets a fully hadronic final state in events with four or more jets and large missing transverse momentum. No significant excess over the Standard Model background prediction is observed, and exclusion limits are reported in terms of the top squark and LSP masses. In addition to the current results, prospects and plans for stop searches in the LHC Run 2 will be discussed.
