This report presents the past results, current status and future plans for DAMIC: a search for low-mass dark matter particles with low-noise CCDs. We summarize the extensive laboratory efforts on the characterization of the CCDs and the calibration of their response to potential dark matter signals and radioactive backgrounds. Recent results include exclusion limits on the spin-independent scattering of WIMPs with silicon nuclei and on the absorption of eV-scale hidden-photon dark matter by valence electrons. A 40 g 7-CCD array started operation in February 2017 and data acquisition is ongoing, with results expected in 2018. We outline the future plans for DAMIC-1K, a 1kg 50-CCD array with an ionization threshold of 2 e − .
