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.

“…Although it seems to be a prominent solution, the only file type taken into consideration was JPEG. It represents less than 1% of the entirely possible infected file types [102]. Therefore, an extensive work should be done to compare at least some of the important file types before and after the encryption process.…”

Ransomware remains an alarming threat in the 21st century. It has evolved from being a simple scare tactic into a complex malware capable of evasion. Formerly, end-users were targeted via mass infection campaigns. Nevertheless, in recent years, the attackers have focused on targeted attacks, since the latter are profitable and can induce severe damage. A vast number of detection mechanisms have been proposed in the literature. We provide a systematic review of ransomware countermeasures starting from its deployment on the victim machine until the ransom payment via cryptocurrency. We define four stages of this malware attack: Delivery, Deployment, Destruction, and Dealing. Then, we assign the corresponding countermeasures for each phase of the attack and cluster them by the techniques used. Finally, we propose a roadmap for researchers to fill the gaps found in the literature in ransomware’s battle.
