Explanation

Cross-VM Cache Side Channel Attacks make it Vulnerable: One of the most sophisticated forms of attack is the cross-VM cache side channel attack that exploits shared cache memory between VMs. A cache side channel attack results in side channel data leakage, such as cryptographic keys. In cases where there exist shared hardware resources, the side channel attack exploits information obtained from the usage of, for example, Central Processing Unit (CPU) core and high level cache memory as opposed to exploiting theoretical weaknesses like the brute force attack.
