Introduction
There are several issues of viruses have been encountered by different IT users and these viruses
are malware, trojan, spyware etc. Each and every type of virus is harmful for computer and
network users. It has potential to damage systems, its information and network connections.
Malware is considered most vulnerable virus that is difficult to recover. Ransomware is a type of
malware and various harmful cases of this virus attack have encountered by network and
computer users. Not only a common user but also large business organizations could not get
prevention from ransomware attack. I opine that to get rid of this problem, it is necessary to use
some appropriate strategies by developers and security experts. Moreover, it is also essential for
users to be aware about major risks and security concerns of ransomware. The purpose of
making this report is to emphasize on security concerns, strategies and future trends of
ransomeware (Usa.kaspersky.com, 2017).
Background
Before start discussion about ransomware in detail, its background will help to understand it.
Ransomware is one of the malicious software solutions. The main intension of ransomware is to
hold computer and extract files from system without owner’s permission. It is known as
unauthorized access of data. In past days, ransomware was commonly known as AIDS that was
released in 1989 (Recorded Future, 2017). The key determination of this was to encrypt the file’s
name in computer system of victim and after this, attacker asked hefty amount from victim to get
repair tool for ransomware attack. Furthermore, the introduction of RaaS also created various
problems for users. With the help of RaaS, the skills of attackers to launch ransomware were
increased enormously (Security Intelligence, 2017). Here RaaS stands for ransomware-as-a-
service. This service of ransomware virus was developed to put bad influence of malware on

victim’s data and system’s environment. According to analysis, ransomware was considered
most dangerous cyber threat. It had potential to infect victim’s personal computer through
various sources such as by visiting to unsafe, fake and suspicious websites, by opening unknown
emails and its attachments and by clicking on malicious links that are in emails, posts and other
received content by victims. In this way, on the behalf of this historical analysis I can say that
ransomware was very destructive by nature. That is why at that time users were also not able to
get better security for this attack.
Risk and Security Concerns of Ransomware
From above discussion we got to know about vulnerability of ransomware. Now due to this
vulnerability what kind of risks can be encountered by computer and network users, we will
discuss here in detail.
Risks of Ransomware
1. The first risk that related to ransomware is erasing of all data from computer system in
which it has spread. If there is no backup of computer files then it is very hard to recover
whole data (Rains, 2017).
2. Other risk factor is related to maintenance of security of sensitive data that is stored into
network databases. With the help of this malicious virus, hackers can easily access data
from databases by injecting virus scripts into it. These scripts not only access data from
database but also damage the whole database (TechRepublic, 2017).
3. Due to ransomware, the issues of development of fake websites is also increasing to
attract people towards those websites and to access their personal and credit card
information. The links of these websites are distributed through ads on popular websites
to redirect visitors on it to collect their essential information (Zetter et al., 2017).

4. Phishing has also increased due to ransomware. Cyber-attackers can easily send
vulnerable codes through emails to users with executable programming files. After
downloading, these attachments spread into the boot sector of computer and cause wide
range of damage.
These are some essential risk factors of ransomware that must be taken into consideration
seriously by developers and as well as by users (Microsoft.com, 2017).
Security Concerns of Ransomware
The above discussed risk factors include various security and privacy concerns of ransomware.
Hacking, phishing and any other kind of vulnerable attack through ransomware leads to security
issues of sensitive information of users. Besides this, some other important security concerns
exist regarding ransomware. The security concern is regarding enhancement in PC performance
problems. Ransomware has potential to slow down the system at large extent and due to this all
important application work in slow pace and give poor performance. Ransomware works at
background in any system or network, so most of the background processes got affected (Team,
2017).
Due to ransomware, the interruptions from pop-ups and spam also increased. The pop-ups and
spams are harmful enough and have potential to hijack victim’s browser and collect confidential
information. Next security concern that is related to ransomware are unexplained behavior of
personal computer (Healthitoutcomes.com, 2017). Ransomware causes unexplained behavior for
browser. It means, this behavior is difficult to identify by users and they become victim. The
main changes that include in behavior of personal computer are installation of unknown toolbars
into browser that are unexpected for user, unknown amendments in home page of browser and
mistrustful results for search. Each and every security concern can give more vulnerable

outcomes if proper security strategies or techniques will not be used at level of security experts
(Crowe, 2017).
Strategies to address security concerns of Ransomware
Due to instant increase in ransomware attacks and its vulnerable impacts, it has become
essential to find out strategies to identify these issues. In upcoming paragraphs, I would
emphasize on some important strategies that will help to address ransomware.
1. Identify the signs of Ransomware
2. Monitor the Trends
3. Awareness about New Version of Ransomware
4. Take Sound Backups
Identify the signs of Ransomware
The identification of ransomware can be done through its symptoms. The slow performance of
system, unknown behavior of computer applications and browsers and unavoidable call to
technical support confirms that ransomware has entered into system. It is a convenient way to
recognize signs of ransomware, but users need to be careful while doing this (Digital Guardian, 2017).
Monitor the Trends
The past records about availability of sources of ransomware and their impacts might be helpful
for IT users to get rid of this problem. For example, in Russia and Eastern Europe in 2009, the
main source of ransomware distribution was email distribution with attachments. Moreover,
malware laden advertising, malicious websites and sneakiness download were also included in
overall process of distribution of malicious ransomware. Besides this, historical events about
6 | P a g e

malware also described the overall range of cost that had to pay by victims for ransomware
attacks and this range was of $60 to $1200 (Lerner, Tuttle, McDonald & Tuttle, 2017).
Awareness about New Version of Ransomware
Instead of using past records of information about ransomware attacks, the awareness about new
versions of this malicious software is also required. There are different types of ransomware such
as CryptoLocker, CTB and CryptoWall. These versions are harmful and flexible enough to
customized according hackers’ requirements. That is why now cyber-criminals or attackers have
become more active to collect confidential information from databases. This knowledge can be
helpful to get suitable security tool to control impact of ransomware (Bailey, 2017).
Take Sound Backups
It is also a suitable way to identify ransomware into system. If a user is taking sound data backup
periodically then it is sure that incursion of ransomware can be identified easily. The backup of
data should be clean and clear. But if any unwanted changes will be seen in backup that is
connected via network to different computers then it can be measured that virus attack is
implemented and it has impact on backup. After getting this information, further action should be
taken quickly to remove ransomware.
Now by using above strategies we can address ransomware into a computer system or a network.
The knowledge about these strategies is important to have by all IT users. After analyzing that
how ransomware can be identified into system or network, now in segment of report, I will
discuss about techniques that must be used to restrict influence over ransomware.

Strategies to control Ransomware
Following strategies will help to control ransomware.
 Use of Updated Security Software
 Share the Information about Security Standards
Use of Updated Security Software
Anti-virus and other traditional security software solutions are not so much beneficial to resolve
problem of ransomware (ERM Software, 2017). These are only suitable for controlling less
vulnerable viruses. That is why, it is time to use some advanced available techniques to remove
ransomware. The recent products are strong enough to identify and fix this harmful virus. Here,
user just need to keep these security software solutions up to date and configuration should also
be done accurately. If configuration will not be fine then required outcomes cannot get by users.
These new software solutions provide maximum level of security. Moreover, all operating
systems, web browsers and other web applications that are in computer systems must be updated
and patched on regular interval. Updates and security patches of essential software components
in a system enhance overall security and privacy of that system (Webroot.com, 2017).
Share the Information about Security Standards
Other strategic solution that can be used to resolve problem of ransomware is increase awareness
among people about latest security standards that can be used to get protection from malware
attacks like ransomware, spyware etc. (Osborne, 2017). This awareness can be provided through
help desks, security forums and subscribing to intelligence services for threat. Moreover, in an
organization, the problem of ransomware exists then periodic corporate training should be given
to all levels of employees to maintain security of computer systems and networks. It is also

necessary to provide them knowledge that when security tools should be updated and installed
into systems (Capgemini.com, 2017).
Do not accept Suspicious Emails
It is important to do at users’ end that they do not accept any kind of suspicious email, message
and file. If in their online accounts, any unknown entity is found then that should be considered
as spam and must remove from system in one click. It is important because these unknown
entities are sent by hackers to different victims with harmful executable scripts and when those
entities are used by victims then they spread into system and damage whole important data and
files.
Try to Block
The blockage of any unknown entity into system is a good way of protection. It can be achieved
by using blocking software solutions such as ad blocker, security patches etc. These solutions
recognize the harmful entity and give alert to user. On this alert, user can block that item to enter
into system and can maintain long term security.
The above discussed techniques are more powerful to restrict ransomware as compare to
conventional techniques. All users who are using these techniques, they are satisfied with
services of these techniques. Furthermore, I would like to say that backup and recovery is
necessary for every database. It is possible that an instant attack of ransomware can destroy
whole database in case of absence of any security tool. In this case, if backup will be available
then recovery can be done easily of whole database. Therefore, this technique should also be
used strictly by users.

Conclusion and Future Trends
To sum up, I can say that whether ransomware has putting its bad impact on IT users then on
other side, various new and advanced solutions are developed for prevention. It is required for
users to have knowledge about those solutions to resolve issue of ransomware or any other
malicious virus. Besides this, the future trends of ransomware should also be in knowledge of
people to be careful in advance and maintain high level security. The future trends of
ransomware include that it will become in future more attractive tool for hackers for hacking,
more attacks are designed to discourage and humiliate the victim, spam campaigns will be
started to target security etc. Therefore, advanced level security should be maintained at end of
security experts and other IT professionals. Otherwise, heavy loss can be occurred and people
will become more worried about their online information (Solutions, 2017).
