Breaking Container Boundary Using Side Channel Attack

With the improvements in technology, hackers are also getting equipped with better rigs day by day. For every new technology being developed to secure cyber space, hackers are trying to research various attack vectors to penetrate them, ultimately rendering them somewhat useless, if things go wrong (which go wrong every now and then). Apart from usual attack vectors in software, hackers have started exploiting the hardware side of computing infrastructure; which has given birth to some famous attacks (e.g. Meltdown, Spectre, Fan-smitter). This paper presents yet another attack vector, which uses temperature pattern of CPU dice as transmission medium to leak data covertly, and then uses that to make containerized processes talk to each other. The paper talks about motivation behind the research, design and analysis of covert channel, challenges, and possible countermeasures against it.

Presented at Security Fest 2024.
