Rare Decays at the LHCb: from beauty to strange

Rare decays are fundamental indirect probes of physics beyond the Standard 
Model. In recent years, several rare beauty hadron decays are showing 
anomalies that could be an early sign of new dynamics. 
The LHCb experiment is providing world best results in beauty and charm 
hadrons rare decays and is recently expanding its physics programme towards 
rare strange hadron decays.  The status of these rare decay searches at LHCb 
is reviewed and recent results are presented. Prospects for future 
measurements are also outlined.
