The article cites data from the KnowBe4 Q3 2021 Quarterly Threat Trends report, which shows a significant increase in the use of these unknown attack vectors in ransomware incidents.

• The article suggests that cybercriminals are constantly evolving their tactics and techniques to bypass security controls. They are using innovative methods, such as exploiting vulnerabilities in remote desktop protocols (RDP) and leveraging social engineering tactics, to gain initial access to target systems. These unknown attack vectors make it challenging for organizations to defend against ransomware attacks effectively.

• The article emphasizes the importance of a multi-layered security approach and continuous employee security awareness training. It recommends that organizations stay vigilant, keep software and systems up-to-date, implement strong access controls, and educate their employees on the latest cybersecurity threats and best practices. Proactive measures are crucial in mitigating the risks posed by the surge in unknown attack vectors used in ransomware infections.
