How was EternalBlue discovered
EternalBlue is a computer exploit developed by the U.S. National Security Agency (NSA). It was leaked by the Shadow Brokers hacker group on April 14, 2017, one month after Microsoft released patches for the vulnerability.
What is EternalBlue exploit
EternalBlue is a Microsoft exploit which was used by the NSA in intelligence gathering operations. The exploit, officially named MS17-010 by Microsoft — gave the US National Security Agency (NSA) backend access to devices running Windows operating systems like Windows XP and Windows 7.
What is an exploit program
An exploit (in its noun form) is a segment of code or a program that maliciously takes advantage of vulnerabilities or security flaws in software or hardware to infiltrate and initiate a denial-of-service (DoS) attack or install malware, such as spyware, ransomware, Trojan horses, worms, or viruses.
What versions are affected by EternalBlue
The MS17-010 patch was designed to fix the SMBv1 software flaws for all supported Windows operating systems, including Windows Vista, Windows 7, Windows 8.1, Windows 10, Windows Server 2008, Windows Server 2012, and Windows Server 2016.

This CVE is in CISA's Known Exploited Vulnerabilities Catalog
| Vulnerability Name | Date Added | Required Action |
|---|---|---|
| Microsoft SMBv1 Remote Code Execution Vulnerability | 02/10/2022 | Apply updates per vendor instructions. |
What is CVE 2017 0144
Description. A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server.
What is CVE-2017-0144 original exploit
Eternalblue itself concerns CVE-2017-0144, a flaw that allows remote attackers to execute arbitrary code on a target system by sending specially crafted messages to the SMBv1 server.
What is the vulnerability of CVE-2017-0144
Description. A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server.
What is exploit code
An exploit is a program, or piece of code, designed to find and take advantage of a security flaw or vulnerability in an application or computer system, typically for malicious purposes such as installing malware. An exploit is not malware itself, but rather it is a method used by cybercriminals to deliver malware.
What does an exploit developer do
Exploit development is essentially the act of finding vulnerabilities in software and applications and establishing how they can be used to overtake a targeted system.

Description. A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server.
Which versions are affected by Log4j vulnerability
Technical Details. The CVE-2021-44228 RCE vulnerability—affecting Apache's Log4j library, versions 2.0-beta9 to 2.14. 1—exists in the action the Java Naming and Directory Interface (JNDI) takes to resolve variables.
What attacks was CVE-2017-0144 used in
WannaCry leverages CVE-2017-0144, a vulnerability in Microsoft Server Message Block 1.0 (SMBv1), to infect computers. The security flaw is attacked using an exploit leaked by the Shadow Brokers group—the “EternalBlue” exploit, in particular.
What is CVE 2017 0147
CVE-2017-0147. sa. leak attack is aimed at the SMBv1 server in Windows. The CVE-2017-0147 vulnerability allows an attacker to use specially created packages to get important information from the memory of processes.
What is the name for CVE-2017-0144
Microsoft CVE-2017-0144: Windows SMB Remote Code Execution Vulnerability.

What is an exploit in vulnerability
An exploit is a program, or piece of code, designed to find and take advantage of a security flaw or vulnerability in an application or computer system, typically for malicious purposes such as installing malware. An exploit is not malware itself, but rather it is a method used by cybercriminals to deliver malware.
How are exploits developed
Exploit development is the process of creating code that can take advantage of a security vulnerability in order to gain access to a system or data. By understanding how exploits work, you can not only defend against them but also create your own tools for ethical hacking.
What is the exploit development path
The Exploit Development Student Learning Path provides not only the fundamentals of Windows and Linux exploit development but also covers advanced Windows and Linux exploit development techniques, as well as anti-exploit mechanism bypasses.
