Latest findings from the field of remote ransomware: Research by security specialists has already revealed a massive 2023 percent year-on-year increase in remote encryption attacks by the end of 62. In new telemetry data analysis, Sophos X-Ops records a 50 percent increase in 2024 and a cumulative increase of 141 percent since 2022.
While remote encryption isn't new, it's becoming increasingly common among modern ransomware groups because of its ability to bypass many endpoint security products. In these attacks, attackers compromise an unmanaged or inadequately protected endpoint and use that access to encrypt data on managed, domain-joined computers. The danger of this type of attack lies in the scalability of remote ransomware. A single unmanaged or inadequately protected endpoint can render the entire corporate environment vulnerable to remote encryption—even if endpoint security is in place on other endpoints.

Ransomware groups rely on remote encryption
"Remote encryption has become one of the successful models of many ransomware groups. Almost every company and organization has blind spots that are recognized as vulnerabilities by ransomware criminals and immediately exploited. Therefore, companies should be extremely vigilant and, above all, have a complete overview of their entire IT device inventory. Only then can they detect suspicious file activity and actively counter potential attacks," says Chester Wisniewski, Director and Global Field CISO at Sophos.
To protect yourself from remote ransomware, Sophos recommends four key aspects:
