![]() ![]() The developer writes the malicious program that encrypts and potentially steals the victim’s data. In the RaaS model, there are at least two parties who establish a business relationship: the developer and the affiliate. This model is different from the traditional ransomware attacks in the past, where a cohesive team both builds the malware and executes the attack. More critically, this also allows non-technical affiliates to successfully execute ransomware attacks. This subscription-based service has grown in popularity as it provides a low barrier to entry for cybercriminals to get into the ransomware business and become an affiliate. In recent years, we have seen the rise of “ransomware as a service” (RaaS) due to its ability to yield huge profits to criminal organisations. How have ransomware groups like REvil optimised their business model? That group morphed into REvil and is now among an elite group of cyber extortion gangs that are responsible for the surge in debilitating, high-profile attacks that have made ransomware among the most pressing security threats to businesses and nations globally. ![]() Through malicious advertisements and malware tools, hackers infect victims through drive-by downloads when they visit a malicious website. At the time, they were mostly focused on distributing ransomware. Investment in specific DDoS protection is relatively low, the survey found, with attention turning to application data breaches, network attacks and malware, despite 60% of respondents saying they are worried about DDoS attacks.īoth Cert-UK and GovCert in Switzerland recommend any organisations targeted by DD4BC should file a criminal complaint with local law enforcement organisations.While REvil (also known as Sodinokibi) may seem like a new entrant in the world of cybercrime, they made their appearance working with a group known as GandCrab in 2018. However, a survey conducted at Infosecurity Europe 2015 in London in June revealed complacency about DDoS attacks is putting businesses at risk. While the potential for threat actor evolution and increased DDoS capability is present, the ASERT report said well-prepared organisations should not have any trouble defending against such attacks if they use a combination of organic detection, classification, traceback and mitigation techniques and cloud-based DDoS mitigation services.
