Types of Cloud Malware Attacks and How to Defend Against Them

Malware in the Cloud: Protecting Yourself Based on Your Cloud Environment |  Tripwire

There are a number of different types of malware that can impact your cloud environment. Here are some of the most common ones:

  1. DDoS Attacks
    Distributed denial of service (DDoS) attacks are one of the most common types of cloud malware. In a DDoS attack, the attacker sends a flood of traffic to your system in an attempt to overwhelm it and take it offline. DDoS attacks are designed to take a target website offline by overwhelming it with traffic from multiple sources. This can include botnets, which are networks of hijacked devices used to carry out an attack. DDoS attacks can be very disruptive to your business and can cause significant financial damage.
  1. Hypervisor DoS Attacks
    Hypervisor denial of service (DoS) attacks exploit vulnerabilities in the hypervisor layer, which manages and allocates resources to virtual machines. This can allow them to gain access to your data and systems, or even take your environment offline. A successful hypervisor DoS attack can crash the hypervisor or take down an entire cloud infrastructure.
  1. Hypercall Attacks
    In a hyper call attack, the attacker sends specially crafted requests to your hypervisor in an attempt to extract information or take control of your systems, resulting in the execution of malicious code. This can allow the attacker to gain access and control over the entire cloud environment.
  1. Hyperjacking
    A hyper jacking attack occurs when an attacker takes control of a virtual machine and uses it for their own purposes, such as launching cyberattacks or stealing data. During a hyper-jacking attack, the attacker takes over your session and can access your data and systems without your knowledge or permission. This can allow them to steal your data or even damage your systems.
  2. Exploiting Live Migration
    Finally, exploiting live migrations is a new type of attack that is becoming more common. Cloud providers use live migration to move running virtual machines from one physical server to another without downtime. Attackers can exploit this process to steal data or install malware on target machines. Live migrations are often not properly secured, enabling malicious actors to access sensitive data or even take control of systems.
