A vulnerability has reappeared, which had been recorded for 3 months. In this case, it is SMBGhost, an exploit that works as the gateway to the operating system so that hackers can access the information without restrictions.
This security flaw on Windows 10 computers has caused the attention of the United States Cybersecurity Agency, who have raised concerns about this failure with the Windows server message blocking protocol.
This is a problem initially solved by Microsoft months ago, where they published a security patch to prohibit the entry of attackers to the Server Message Block, a network protocol that allows sharing files, printers, among other elements between nodes of a network that has with the connection of different computers.
Although the above was solved, the Security Agency mentioned that thousands of computers with internet access are still vulnerable.
According to the guys at Tech Crunch, the infecting capabilities of this vulnerability are greater: Because the code is wormable, it can spread across networks, similar to how the NotPetya and WannaCry ransomware attacks spread around the world, causing billions of dollars in damage.
Another quite relevant curiosity is that There is an old version of the operating system that does not support the source of the error, known as the SMBv3 1.1 understanding., and this is Windows 10 in versions prior to 1903. In other words, if your computer did not get a Windows 10 update since May 2019, then your PC is not being vulnerable to this gap. If you checked the above, then you will have to update your operating system with the steps you will see in the following lines.
How to update Windows 10 to its latest version
As everything has a solution, surely you should have already received the Windows message for you to schedule the update on restarting the computer. But, if you don’t see it yet, you can go to the Start, press on the option Settings> Update and security Y click on the Restart now button. You can also schedule the update at a specific time, although we recommend it as soon as possible.
