Part A
Introduction
On April 24, 2017, the Newark city hall computer organization were suffered from
Ransomware cyber-attack and it was one of the largest data breach attacks in the history of
cyber-crime. It is very difficult to improve the security of personal data or computer networks
because hackers use high-level program for entering into the computer devices of users. The
aim of this study is to critically review the Network city hall cyber-crime and identify how
this attack occurred and how the company reduced such kind of data breach issue. Moreover,
this report also focuses on the problem of asynchronous I/O activity and provides suggestion
to overcome such kind of issue.
Question 1: 'Newark City Hall Computers Hacked with Ransomware'
What the problem was?
It is observed that the Newark city hall computer was faced the issue of a ransomware
attack on April 24, 2017. The ransomware attack harms the Australian organization and users
by collecting their personal information (TC Palm, 2019). The NHS directors evaluated that
bitcoin infection flies up and many hackers use this process for obtaining money from
consumers. It is observed that organization developed a computerized key that obtained by
attackers with the help of ransomware attack where they produced a huge amount of traffic
signals and transferred to the network of the organization (Security Affairs, 2019). During
this attack, the developers identified that computer system just opens automatically and
processed an electronic type of bitcoin. Moreover, through ransomware attack numbers of
consumers were lost their personal data and information and hackers entered into the
computer devices by using adversary and psychological militant states.
How and why it occurred?
Such kind of cyber-attack was occurred due to lack of security and use of unauthentic
networks because employees accessed their personal accounts in the unauthorized servers.
However, developers also identified that the hackers developed a huge amount of traffic
signals with the help of malware software and transferred on computer devices that occurred
the issue of ransomware (Hack Buster, 2018). However, the ransomware attack has occurred
because employees and users did not adopt a high level of security tools and attackers easily
entered into the organization’s servers. Use of older PC and windows are also risk factors that
increased the rate of ransomware and company was lost their private details and hackers
