Working principle of ransomware
Ransomware is defined as software which is used to publish the victim’s information. There are many simple ransom wares that are very easy to hack of unlocked and to reduce this type of problem malware developed new technology that is cryptoviral extortion [1]. It is a very common problem for all computer systems and it is very harmful to computer devices. The main objective of this report is to describe the impact of ransomware on the society and evaluate potential threats and risks of this software. Ransomware is one of the biggest problems for society and it affects human body systems, users, home appliances, potentially harmful for any organization, increase financial problems, and permanent loss of information or data. This report is explaining the working principle of ransomware and potential threats and risks of ransomware [2].
Locker ransomware is defined as a ransomware which is used to access any computer resources. This type of ransomware is used to lock the computer system or devices and ask to pay money in order to restore data or information. The locked computer can access user and only user or customer allowing to communicate with ransomware and pay the ransom. This is only designed to prevent access to the computer device and there are many organizations that are using this for security purpose [2].
The main purpose of this ransomware is to determine and encrypt data or information stored in the computer systems and provide a platform to obtain the decryption key. In this modern generation, there are many people who are storing personal data or information in computer systems and devices. Backup is one of the most common processes to protect data or information and Crypto ransomware store human personal data and it uses internet of thing to store data in computer systems. This is an advanced ransomware which reduced hacking systems and it increased security system for all people and organizations [3].
Karger is a type of Mac ransomware which is established in 2016 and this is the first type of Mac which infects the Mac running OS X. This was injected into the users and when any user downloads this software which can infect with the ransomware. Once this infected than it waits around 3 days and after that, it encrypts around 300 data files and users pay to access this service in computer devices [4].
It is the most common type of ransomware which is used to encrypt data or information file in computer systems. This ransomware encrypts all data files of infected customers and demand for money to restore data of information from the computer system. It also works when a human is not connected with internet connections [5]. This ransomware sends an email to user and demand money to access their data or information.
Locker ransomware
It was established after the crypto locker and it reduced drawbacks of the crypto locker. This type of ransom is used to decrypt data or information of any computer system and to access this service user give money or fund to the organization after that they can use this service. There are many types of the crypto wall such as crypto bit, crypto defence, and crypto wall 2.0, and 3.0 [6].
Ransomware is a type of software which is used to protect data or information of computer system and it is increased rapidly in the last few years. There are many steps through which ransomware can access any computer system. One of the greatest mutual delivery schemes is phishing spam add-ons that come to the dupe in an email, masked as a folder they must trust [7]. Once they’re copied and opened, they can revenue over the target’s processor, particularly if they have integral communal engineering gears those artificial operators into letting managerial admission. There is many another form of ransomware such as NotPetya, exploit security holes to contaminate processors without demanding to trick operators. There are few steps involved in ransomware process such as
- The malicious software plots on the processor through an unsafe email accessory or transfer. The malware produced a fault in the working scheme in order to run unsafe code on your processor.
- After that ransomware encrypt personal files of the computer system and mover into the computer system
- The hacker demand money to restore data or information to their computers by using various online websites [8].
Ransomware is one of the most common problems for users and customers and it is increased rapidly in the last few years. They sent a fraud E-mail on people accounts and encrypt all data or information which is stored in computer systems and devices. After that, they communicate with the person by online websites and demand money or fund to restore their personal data or information. This problem increases by spam messages and e-mails and there are many threats and risks occur due to this problem such as affects human body system, harmful for computer system and data, increase many hacking system, through which many people are learning hacking programmes which are a very serious problem, can effects on children and adults, and reduced security systems, and also increase financial problems. There are mainly two types of ransomware used at that time for encryption purpose such as encrypting ransomware and locker ransomware [8].
Encrypting ransom ware involves many advanced data structure for encryption of data and it is used to block human computer systems and devices. This ransomware reduces security systems and hacks computer systems by sending spam e-mails and demand money to restore data or information. This process is very harmful to human-computer systems and also increases human health risks [9].
Advanced ransomware
Locker ransomware is also called as a computer locker and it locked human-computer systems and devices by using some algorithm process. This ransomware inserts in computer systems by e-mail and other process and after that, it blocks all personal files and data in computer systems and demand money by online websites. This ransomware blocks all files and may be lost in your personal data which is very harmful to your computer systems [9].
WannaCry is one of the most common cybersecurity risks and it is increased rapidly in the last few years. In 2017 there are many cybersecurity attacks observed in which WannaCry one of the biggest security attack is identified. On May 12, 2017, WannaCry affected around thousand computes systems worldwide and it is a part of the ransomware attack. Ransomware was defined as infectious because it has the ability to feast across a community and an organization system by exploring susceptibility in computer systems [9]. At that time WannaCry hacked many computer systems and encrypt all personal data or information files after that they demand money or fund to restore data or information. Therefore it is the very serious problem for all users and they always communicate with e-mail and after that, they hacked your data files and blocked them.
Ransomware is one of the biggest problems for all users and organizations because it encrypts the human-computer system and blocks all personal data files. To reduce this type of problem there are few mitigation process are used such as educate employees for data security, use proper data backup system for personal data files, restrict code execution, restrict system or computer devices access, update software regularly, use security systems, robust filtering process, blocking attachments, removing spam emails and messages [10]. All these are very common strategies and mitigation to reduce ransomware problem in which there is the main two most mitigation process which can be sued for this problem such as use proper backup plan and robust filtering. Robust filtering is used to block spam messages and e-mails and it reduced this type of problem by 40% [11]. Therefore to reduce ransomware attack people can use cloud computing technology for data backup and they can use robust filtering process both can help to reduce this type of security risks and also increase data or information security [12].
Conclusion
Ransomware is one of the biggest problems in all countries and it is estimated that in 2017 around one thousand computer systems were hacked by ransomware. There are mainly two types of ransomware are used such as Encrypting ransomware and locker ransomware. This report described different variants of ransomware and also explained the mechanical process of ransomware. There are various processes through which this problem can be reduced which are described in this report. Ransomware attack can be reduced if any person uses proper data backup plan like cloud computing system and use a robust filtering process to block spam messages both are main two mitigation process through which this security risk can be resolved.
