  In this paper, we analyse the results and claims presented in the paper
\emph{`Are Randomized Caches Truly Random? Formal Analysis of Randomized
Partitioned Caches'}, presented at HPCA conference 2023. In addition, we also
analyse the applicability of `Bucket and Ball' analytical model presented in
MIRAGE (Usenix Security 2021) for its security estimation. We put forth the
fallacies in the original bucket and ball model and discuss its implications.
Finally, we demonstrate a cache occupancy attack on MIRAGE with just $10\%$ of
total cache capacity and extend the framework to establish a covert channel and
a template-based fingerprinting attack.
