Question

A cloud engineer is receiving multiple alerts from the infrastructure monitoring agent. The alerts state that all the VMs in the public subnet are at 100% CPU utilization. However, when the engineer checks the network utilization of the VMs, the network throughput is at normal levels. Which of the following is the most likely cause of this issue?

Options

  • ARansomware
  • BCryptojacking
  • CDDoS
  • DZombie instances

Explanation

Cryptojacking occurs when an attacker exploits cloud resources to mine cryptocurrency without the owner's consent. This typically results in high CPU utilization across multiple VMs while keeping network usage relatively low, as mining operations are CPU/GPU-intensive but do not require significant network bandwidth. The cloud engineer should investigate running processes and check for unauthorized mining activities.
