2 LITERATURE REVIEW

Ransomware attacks have become an increasingly

prevalent and damaging threat to organizations of all

sizes and across all industries. In recent years, the rise

of cloud computing has brought with it new

challenges and risks for organizations facing

ransomware attacks. This literature review aims to

provide an overview of the existing research on the

intersection of cloud computing, ransomware attacks,

and digital forensics investigations. The literature

suggests that ransomware attacks are a significant

threat to cloud computing environments due to their

distributed nature and the complexity of the systems

involved. Ransomware attacks can be carried out

through a variety of methods, including phishing

emails, exploit kits, and remote desktop protocol

(RDP) attacks. In a cloud computing environment,

these attacks can be more difficult to detect and

respond to due to the lack of visibility into the

underlying infrastructure.

Digital forensics investigations in a cloud

computing environment also present unique

challenges and limitations. The distributed nature of

cloud systems makes it difficult to collect and analyse

data, vital data may be lost during a ransomware

attack, and maintaining compliance with legal and

regulatory requirements are some of these

difficulties.To address these challenges, the literature

suggests a range of potential solutions and best

practices. These include the use of cloud-based

incident response tools and procedures, such as

backup and recovery systems, threat intelligence

feeds, and vulnerability scanning tools. Other

solutions include the development of specialized

forensic techniques for cloud systems, such as

network forensics and memory analysis, as well as the

implementation of strong access controls and

authentication mechanisms.

Overall, the literature suggests that ransomware

attacks in a cloud computing environment pose

significant challenges for organizations and digital

forensics investigators. However, by adopting best

practices and utilizing specialized tools and

techniques, organizations can mitigate the risks

associated with ransomware attacks and improve

their ability to detect and respond to these threats in a

timely and effective manner.

3 BACKGROUND STUDY

The rise of cloud computing has brought about

numerous benefits for organizations, including

increased scalability, cost efficiency, and flexibility.

However, the increasing adoption of cloud computing

has also brought with it new challenges and risks in

the realm of cybersecurity. Ransomware attacks are

one of the most pressing threats facing organizations

today, and the distributed nature of cloud computing

systems can exacerbate the impact of these attacks.

An organization's data is encrypted by

cybercriminals using ransomware, and they then

demand payment in exchange for the decryption key.

The impact of ransomware attacks can be devastating,

including the loss of critical data, financial losses,

reputational damage, and even operational

disruptions. Ransomware attacks can be carried out

through a variety of methods, including phishing

emails, exploit kits, and RDP attacks.

Cloud computing systems are particularly

vulnerable to ransomware attacks due to their

distributed nature and complexity. These systems are

made up of multiple components, including virtual

machines, storage devices, and networks, which can

make it difficult to identify and respond to

ransomware attacks. Furthermore, cloud computing

environments are often shared between multiple

users, which can increase the risk of an attack

spreading to other systems.

For digital forensics investigations, cloud

computing platforms can present unique challenges

and limitations. The distributed nature of cloud

systems might make it difficult to maintain legal and

regulatory compliance while gathering and analysing

data. Additionally, the dynamic nature of cloud

systems can make it difficult to establish a clear

timeline of events during a ransomware attack, which

can hinder the effectiveness of a digital forensics

investigation.

To address these challenges, organizations must

adopt best practices and utilize specialized tools and

techniques for detecting and responding to

ransomware attacks in a cloud computing

environment. This includes the use of cloud-based

incident response tools and procedures, such as

backup and recovery systems, threat intelligence

feeds, and vulnerability scanning tools. Organizations

must also develop specialized forensic techniques for

cloud systems, such as network forensics and

memory analysis, in order to effectively investigate

ransomware attacks in the cloud.

In conclusion, the increasing adoption of cloud

computing has brought with it new challenges and

risks in the realm of cybersecurity, particularly in the

context of ransomware attacks. Organizations must

adopt best practices and utilize specialized tools and

techniques in order to effectively detect and respond

to ransomware attacks in a cloud computing

environment, and to conduct digital forensics

investigations in their aftermath. By doing so,

organizations can mitigate the risks associated with

ransomware attacks and improve their overall

security posture.
