Malware attacks can happen on the cloud, just like they do on personal computers. While cloud providers put up strong security measures to prevent these attacks from happening, cybercriminals can still find loopholes they can use to spread malware in the cloud.
Cloud malware can compromise business data. Therefore, if you’re using cloud services, you’ll want to make sure the platform is well-protected against malware.
What is Cloud Malware?
Cloud malware is a malicious code designed to infect and exploit cloud environments. Like traditional malware, it can steal data, disrupt operations, or give hackers unauthorized access to cloud-based systems, applications, or storage.
Cybercriminals use different methods to infect and spread malware in a cloud environment. These methods include:
- Infected file uploads
- Phishing & Credential Theft
- Compromised Cloud Applications (SaaS Attacks)
- Misconfigured Cloud Security
- Cloud Cryptojacking
Cloud environments are ideal for spreading malware because:
- They’re exposed to the internet, making them easily accessible to potential attackers.
- Attackers can easily study and exploit common configurations.
- The cloud has many components like virtual machines (VMs), containers, and storage buckets, each potentially serving as a weak point for cyber threats.
What Are the Most Common Types of Cloud Malware Attacks?
DDoS Attacks
A Distributed Denial of Service (DDOS) is one of the most dangerous types of attacks used to breach public cloud environments. In this type of attack, cybercriminals disrupt a server by flooding it with malicious traffic. This traffic mainly originates from different infected computers or IoT devices.
It’s pretty easy to launch a DDOS attack, especially for cybercriminals using botnets. However, defending against it is much harder because attackers can use multiple techniques. A DDOS attack doesn’t compromise an organization’s data. Instead, it makes websites, applications, or cloud services slow or completely unavailable. This can make users switch to a ‘better’ cloud provider.
Hyperjacking
Hyperjacking is a type of malware attack that targets the hypervisor. A hypervisor is a program responsible for creating VMs that isolate virtual environments. If an attacker gets control over the hypervisor, they can carry out several malicious activities, such as unauthorized data monitoring. A hacked hypervisor can run secretly, making it hard for regular security tools to notice the attack.
Injection Attacks
Injection attacks happen when cybercriminals inject malicious code into a system. The code enables them to infiltrate the system and steal data or manipulate a system’s operations. An attacker can use different ways to inject malware into cloud resources. These include:
- Taking advantage of security weak points in the cloud system or applications.
- Using phishing scams to trick people into downloading and installing malware.
- Gaining unauthorized access to cloud accounts and spreading malware through infected files or malicious links.
Exploiting Live Migration
Attackers can also take advantage of live migrations to the cloud to inject malicious code into the cloud system. This type of attack is very unique, therefore not every provider expects it to happen. As such, they might not put the right security measures to protect the system.
Cybercriminals can use a wide range of mechanisms to attack a live migration. These strategies may include the following:
- Migrate resources to a virtual network under their control.
- Make adjustments to migrated systems to make them easier targets of future attacks.
Protect Your Cloud Environment from Cyber Attack
Malicious code can impact anything it comes into contact with, whether it’s in the cloud or elsewhere. However, you can reduce your chances of being a victim by taking the right measures. By staying informed and putting up the right security protocols, you can keep your cloud environment safe and secure.
