EternalBlue is a software vulnerability, specifically a flaw in the design or implementation of Microsoft's Server Message Block (SMB) protocol. This vulnerability, officially known as CVE-2017-0144, allows for the execution of arbitrary code on affected systems. It became publicly known after a group called the Shadow Brokers leaked an exploit developed by the U.S. National Security Agency (NSA). The exploit has remained relevant due to its ability to propagate via SMB and infect systems that have not been patched against it. This vulnerability was notably used as an enabler in the WannaCry ransomware attack. The Cybersecurity and Infrastructure Security Agency (CISA) assessment team identified several unpatched systems vulnerable to EternalBlue and another vulnerability known as BlueKeep (CVE-2019-0708). The team attempted to compromise these systems using both vulnerabilities. While they were unsuccessful with BlueKeep, they were able to exploit EternalBlue on a server, establishing a shell with local SYSTEM privileges. This successful exploitation demonstrates the continued risk posed by EternalBlue, especially on unpatched systems. Various malware strains, such as GoldenHowl, have incorporated the EternalBlue exploit into their arsenal. GoldenHowl can scan remote systems for open ports and determine if the target is vulnerable to the EternalBlue malware. Despite the availability of patches for this vulnerability, many systems remain unpatched and susceptible to EternalBlue-based attacks. Therefore, EternalBlue continues to be a significant cybersecurity concern, necessitating vigilant patch management and system monitoring.
