CYBERSECURITY 2
Introduction
WannaCry is a part of the ransomware that was developed and
implemented in the year 2017 by a crypto worm that targeted computer
running the Microsoft Windows operating systems. It is one of the serious
cyber-attacks which directly impacts on the computing networks and
devices used by companies (Anjana, 2017). Mainly, hackers produce such
kind of attack for earning money and collecting the private details of
companies without taking their permission. This investigation aims to
inspect the key features of WannCry attack and assess their operational
principle along with the real-world example. A walkthrough process will be
included in this report in order to analyze the risk factors that produce
WannaCry type of ransomware attack in the companies. It is very important
to identify the risk elements which increase ransomware type of attacks and
companies require a platform where they can analysis security related
issues linked with computing networks. This report will provide a way
where the students can enhance their skills in the area of cyber-security
attacks and evaluate the impacts of WannCry attack on the personal data
files.
WannaCry Walkthrough
What is WannCry Attack?
WannCry is defined as a cyber-attack that mainly developed by
cryptoworm in tear 2017 from the perspective of hacking. It is a part of a
ransomware attack that has the potential to collect data of victims and
businesses by transporting unauthentic signals to the main server
(Srinivasan, 2017). Such kind of security attack spread rapidly across
numbers of computing devices in May of 2017 and encrypt the sensitive
data of consumers by using malicious tools and networks. It is a common
type of ransomware faced by companies in the year 2017 and 2018 that sent

unwanted signal and systems to the user's devices and performs hacking-
related activities (Arora, Yadav, & Sharma, 2018). There are major two risk
factors which increased the issue of wanna cry in 2017 including lack of
privacy and utilization of unauthentic networks.
A recent study argued that the WannaCry attack includes numbers of
components, for example, a copy of Tor, files including encryption keys, and
a system which encrypts and decrypts information. It arrives on the infected
computing networks in the form of unauthentic signals and networks which
are able to reduce the performance of networks used by companies and
help the criminals to enter into the main server for obtaining reliable data.
The criminals mainly use botnet and malicious process in order to produce
unwanted signals and attack on the computing networks which reduce the
security of data and help to perform data breach-related activities in the
servers (Chen, & Bridges, 2017).
