This software blocks the data of the person and the same is handed over to the person back once the money is received in the form of ransom [1]. The consequences of not giving the ransom can be so bad that the company or the individual can go out of the data no matter how much important or private it is. The report includes the complete analysis of the ransom ware and how it works and its different variants that have been developed over the years [2]. Also the main motive of this report is to understand the threats that have been arising from the ransom ware.
Ransom ware falls under the category of the dangerous malware which creates the drastic effect on the society. The effect is so turbulent that the entire set of the files can be disturbed if the money is not paid on time and the data may be blocked for much of the time. On the other hand if the ransom is paid timely, the user has the power to access the data. If the effect is looked upon in case of the overall disturbance the service sector is the one that gets disturbed mostly. There are businesses whose turnovers are in the figures of the crores, there are humungous transactions which need to be managed [9]
The company prefers to keep the data on the cloud computing basis so that it is manageable anytime and anywhere as it is not possible to carry the documents everywhere. These cloud data is highly exposed to the malware and the services are mostly under the attack of the malware. According to the reports the cost of the cybercrime in the Australia was prevailing at $1.3 billion in the previous year. Generally the payment is made through the crypto currency like Bit coin or the MoneyGram. Therefore it gives the ideas to the hackers to extort more and more money as possible in the fraudulent manner [8].

Mac ransom ware in another kind of the ransom ware that the data from user’s account is to earn monetary benefits through the process. The flow of this kind of malware is just like a walk of the tortoise yet the malware cannot assure the possibility of the non-attack. It has been reported in the financial times that the ransom war costs about $7 trillion in the disasters annually by the year 2021 [4].
Crysis is a super dangerous crypto virus that has been discovered by the experts of security. Since then, the ransom ware has been revamping constantly. According to the latest reports it uses a particular file extension. If the individual gets infected with this variant, and meanwhile the Crysis ransom ware decrypts [2].
The crypto ransom ware was propagated in the year 2014, which was believed to have targeted the computers running on the Microsoft Windows. The malware ultimately displays the message which offered to decrypt the data if payment is made within the deadline otherwise vice versa. Crypto ransom ware uses the human information and through the web of thing it incorporates the same into the PC framework. Most of the individuals are carrying their most confidential data on various applications; even the bank account numbers are being shared [2].
The mechanism of the ransom ware is the most simplest and the easiest one. Thought there are numerous procedures through which the data shall be hacked in a different manner, the process of the ransom ware is the most sober. The method firstly involves the response of the hacker through the spam and the fraud emails. The user gets a particular link on the website due to which, if he clicks on the website the, the spam link puts the data on the pause mode and the ransom are is successful in hacking of the data [3].

In early stages the text messages became the source of the communication but now a days the email are the new source that has been used to send the notification of the spam mail to the customers. Cybercriminals nowadays possess the major techniques which can delete the mails and the communication over the telephone [4].
Unpatched systems
Most of the malwares is set up through the activities of the client. The user does not clicks on the links purposely and the purposefully the client taps on the negative connections and the spam messages that visits or bargains the site.
While all the payment product is contaminated by the theft and tainted infection and hits the affectability purpose of the focused on casualty. As indicated by FBI these occurrences are being alluded to as the blackmail of the payoff product [7].
No differentiation
The criminals do not care much about the target of the computers, and they do not buy the operations rather, they are willing to victimize anyone irrespective of the how dangerous and critical it might get. For example the Social media declared the news of the ransom ware attack and caught the critical applications and responsible for the extortion of the money [8].
Jigsaw ransom ware it is a kind of the ransom ware, an encrypting one that was created in the year 2016. Earlier it was titles as the Bit coin Black mailer, but later it was termed as Jigsaw as the image of the Billy the puppet was showcased which belonged to the Saw film franchise.

After this image a pop up feature of the Billy the puppet will appear with the statement of the version including “I want to play a game” line in exchange of the Bit Coin or MoneyGram [5].
It has been recommended to the individuals to create secure and protected passwords that cannot be hacked by any hacker and to avoid the date of birth, mother name or father name in the passwords as it is easy to catch. The critical important component is that it needs to be critically evaluated so that the protective measures can be taken in advance. For instance the security approaches will be expanded on a larger amount, presentation of the coding procedure so the hackers cannot hack, as far as possible the task of the PC and the structure, reliably redesigning the current projects, the follow up of the solid isolating procedure and obstructing of obscure associations and uncovering the spam messages. Once the payment has been made the client is relieved and feels safe for the data [10].
Conclusion
There are diverse systems through which the issues that can make a problem can be diminished in the number. The strike made by the ransom is of such a worry, to the point that it influences the PC and the client as well as it influences the secretive information of the business. Significantly it is prescribed to the client to scramble the information and utilize the antivirus information keeping in mind the end goal to protect the information and records.
