Ransomware attacks continue to pose a growing threat to organizations as it has emerged as the number one threat, affecting 66% of organizations in 2023 and pulling over $1 billion from the victims. These attacks have increased in frequency and sophistication, resulting in significant financial loss, operation disruption, theft of sensitive data, and reduced productivity rates. Also, it damages the organization\'s reputation and results in the loss of customer trust and compliance violations. An organization needs a comprehensive protection strategy to reduce the frequency of these attacks and the risks they pose. Ransomware Business Model: How These Attacks Are Evolving? In the past, ransomware attacks mainly relied on phishing emails, remote desktop protocol exploits, and vulnerable ports to increase their chances of success. Additionally, these attacks employ evasion techniques to bypass traditional security measures like firewalls or antivirus software. These methods have resulted in famous attacks like WannaCry, TeslaCrypt, and NotPetya. With time, ransomware attackers have evolved and have become more sophisticated, targeted, and profitable for cybercriminals. Below is an insight into the latest trends that hackers adopt to launch a successful ransomware attack: Exploiting Zero-Day Vulnerabilities The shift in ransomware gangs and their sophisticated tactics and procedures (TTPs) raise the number of ransomware attacks. . Previously, REvil, Conti, and LockBit were the famous ransomware gangs, but now Clop, Cuban, and Play are gaining immense popularity by employing advanced hacking techniques like zero-day vulnerabilities. Sophos\'s State of Ransomware 2024 revealed exploited vulnerabilities as the root cause of ransomware attacks. The Clop ransomware gang has used the zero-day vulnerability in the MOVEit Transfer platform to steal the sensitive data of different organizations. This group also targeted the GoAnywhere zero-day vulnerability in January 2023, affecting 130 organizations, and exploited the Accellion FTA servers in 2020. Similarly, Cuban and Play used the same attacking technique to compromise the unpatched Microsoft Exchange servers. Double and Triple Extortion Another reason for the rise in ransomware attacks is the introduction of the double or triple extortion technique. Cybersecurity firm Venafi reported that 83% of ransomware attacks included multiple ransom demands in 2022. Cybercriminals encrypt the data, exfiltrate sensitive information, and threaten to release it or sell it on the dark web if the ransom is not paid in a double extortion scheme.

We dug into studies and surveys of the industry's landscape to get a sense of the lay of the land-both in terms of what's happening and how your fellow IT pros are reacting to it.Ransomware is down, cryptomining is up With last year's outbreak of NotPetya, ransomware-malicious programs that encrypt your files and demand a ransom payment in bitcoin to restore them-became one of the most talked about forms of malware of 2017. Yet at the same time, the actual rates of malware infection began to plummet around the middle of the year, until by December 2017 it represented only about 10 percent of infections. | Malware Studies | NotPetya |
