Weak decays that are naturally suppressed in the Standard Model, such as processes with flavour-changing neutral-currents, are perfect for indirect searches of new physics. These decays allow us to investigate higher energy ranges with respect to direct searches thus representing a fundamental complementary tool. Results on the ATLAS search for the $B_s\rightarrow \mu^+\mu^-$ rare decay will be presented together with the most recent updates on the 2012 analysis that will be published soon. The ATLAS study of $B_d\rightarrow K^{\star}\mu^+\mu-$ is also reported where the parameters $A_{FB}$ and $F_L$ are extracted from the angular distribution of the final state.
