Insights into Regional Development
Ransomware threats and incidents have exponentially increased causing both financial and reputational losses to organizations of all sizes and sectors. Ransomware attacks became the talk of the news when the world was hit by COVID 19 pandemic and people shifted to remote work in large numbers (Brynjolfsson et al., 2020, p. 13-14). Cybercriminals and threat groups are using various types of social engineering techniques such as email phishing, smishing, spear phishing attacks to spread ransomware infections in systems and networks. To protect organizations, users, and IT infrastructures it is important to understand how ransomware works, and how various threat actors use it to exfiltrate confidential data and information. Hence a critical approach toward ransomware infection and its mitigation by using different techniques is discussed and analyzed in this research paper concerning other scholarly articles and papers.
Ransomware: Recent Advances, Analysis, Challenges and Future Research Directions
Computers & Security
The COVID-19 pandemic has witnessed a huge surge in the number of ransomware attacks. Different institutions such as healthcare, financial, and government have been targeted. There can be numerous reasons for such a sudden rise in attacks, but it appears working remotely in home-based environments (which is less secure compared to traditional institutional networks) could be one of the reasons. Cybercriminals are constantly exploring different approaches like social engineering attacks, such as phishing attacks, to spread ransomware. Hence, in this paper, we explored recent advances in ransomware prevention and detection and highlighted future research challenges and directions. We also carried out an analysis of a few popular ransomware samples and developed our own experimental ransomware, AESthetic, that was able to evade detection against eight popular antivirus programs.
Analysis of Ransomware Attack and Their Countermeasures: A Review
Ransomware is a type of malicious software. Computers infected with ransomware have restricted access to the system. It is a malicious program, and money must be provided to the creator of the malicious code to release it. With the substantial increase in the number of ransomware attacks, on May-12-2017, network security issues began to heat up. This article describes the types of countermeasures against ransomware and cyber terrorism. In recent years, ransomware has been under constant attack and has high infectious power: S pora, CryptoLocker, Locky, CryptoWall, Petya, Cerber, S anam, Aris Locker, Jigsaw, WannaCry, and Reveton. Ransomware protection is not any longer 100% free. However, you can secure ransomware through programmed refreshes, antibody establishment, and span backups. Need framework and organization. Figure out how to prevent ransomware from your organization and individual clients. Most ransomware is transmitted via phishing emails. The fastest way is to measure the steps taken by various agencies to stop this malware and decrypt it. The criminals behind the ransomware caused not only largescale damage to sensitive infrastructure but also billions of dollars in benefits from patients around the world. The world is still collecting money from innocent people. Nine types of ransomware, small software, and several examples of malware are studied. The outcomes show that reflected programming and innocuous applications can be recognized. This is a way to stop companies and individuals from ransomware
IRJET- Ransomware and its Evolution with the Covid-19 Pandemic
IRJET, 2021
In this paper, we discuss different cyber threats to corporate infrastructure. Our primary focus is Ransomware(RW), its types, along with its evolution. With the COVID-19 pandemic, the number of cyber attacks have steeply increased due to the home-office working situation. Cases of Ransomware (RW) have doubled as shown by cyber security research conducted in Q1 2020. Traditional network antimalware software and several other packet filtering techniques have also been ineffective against these attacks, this paper also tries to delve into the types of attacks, spread of the malware to multiple systems along with protective measures that can be undertaken to limit its potential of infecting all the systems within a network. We have also tried to show the evolutionary nature of the malware with recent cases showing a different type of attack that emphasizes blended extortion Ransomware attacks where hackers steal confidential information before encrypting it. If victims chose not to pay for a decryption key, attackers will then threaten to release stolen information publicly. This intern results in a catch-22 problem where the target is vulnerable even after backing up systems.
Ransomware Prevention and Mitigation Techniques
International Journal of Computer Applications, 2020
Ransomware is a malware family that using security techniques such as cryptography to hijacking user files and associated resources and requests cryptocurrency in exchange for the locked data. There is no limit to who can be targeted by ransomware since it can be transmitted over the internet. Like traditional malware, ransomware may enter the system utilizing "social engineering, malware advertising, spam emails, take advantage of vulnerabilities, drive-by downloads or through open ports or by utilizing back doors". But in contrast to traditional malware, even after removal, ransomware influence is irreparable and tough to alleviate its impact without its creator assistance. This kind of attack has a straightforward financial implication, which is fueled by encryption technology, cyber currency. Therefore, ransomware has turned into a profitable business that has obtained rising popularity between attackers. As stated by "Cybersecurity Ventures", ransomware is the quickest increasing type of cybercrime. Since, global ransomware wastage expense is predicted to hit 20billionin2021,upfromjust20 billion in 2021, up from just 20billionin2021,upfromjust325 million in 2015 which, is 57X extra in 2021. In this paper, a brief of the recent research in the prevention of ransomware attacks and the best practices to mitigate the attack impact is presented.

A Survey on Ransomware: Evolution, Taxonomy, and Defense Solutions
2021
In recent years, ransomware has been one of the most notorious malware targeting end users, governments, and business organizations. It has become a very profitable business for cybercriminals with revenues of millions of dollars, and a very serious threat to organizations with financial loss of billions of dollars. Numerous studies were proposed to address the ransomware threat, including surveys that cover certain aspects of ransomware research. However, no study exists in the literature that gives the complete picture on ransomware and ransomware defense research with respect to the diversity of targeted platforms. Since ransomware is already prevalent in PCs/workstations/desktops/laptops, is becoming more prevalent in mobile devices, and has already hit IoT/CPS recently, and will likely grow further in the IoT/CPS domain very soon, understanding ransomware and analyzing defense mechanisms with respect to target platforms is becoming more imperative. In order to fill this gap and...
