In this talk, we present our recent research on an emerging threat faced by multi-tenant data centers --- well-timed malicious power loads, or power attacks. We first show that, despite safeguards in place, the current way that power infrastructure is managed in multi-tenant data centers is highly vulnerable to power attacks launched by malicious tenants (i.e., attackers). Next, we discover two types of physical networks in a multi-tenant data center --- thermal network and acoustic network --- which result from the co-location of multiple tenants in a shared data center facility and hence physically interconnect these tenants. More importantly, a malicious tenant can extract information about tenants' runtime power usage out of the thermal/acoustic network and launch well-timed power attacks, compromising the data center availability and leading to power outages. Finally, we highlight a set of defense strategies that data center operators can leverage to secure the power infrastructure against power attacks.
