BEANIE is a tweakable block cipher recently published at ToSC aiming for memory encryption of microcontroller units. In line with this goal, it handles small plaintexts of only 32 bits and has a low latency. In this paper, we propose the first third-party analysis of the two variants of BEANIE. By carefully leveraging structural properties of the cipher and taking advantage of its distinctive attack model, we manage to mount several key-recovery attacks against both the 5+5-round version and the 7+7-round version.
