Yes updates for Windows XP: Microsoft has just released an emergency update for almost all versions of Windows to block the ongoing attacks with WannaCry ransomware (Microsoft is recognized as Ransom: Win32 / WannaCrypt).
So even Windows XP and Windows Server 2003 users can download the security update from the Microsoft Update Catalog even though the company has stopped supporting these versions.
Microsoft recommends that everyone update their systems as soon as possible given the increasing number of attacks.
The infections by WannaCry they first appeared in Europe yesterday, with targeted organizations in different countries. The British National Health System was severely hit by the ransomware, which began to spread in the United States late Friday.
The infection is based on Windows vulnerability originally discovered by the NSA and leaked earlier this year by the group Shadow Brokers. Microsoft has explained that Windows versions that are still supported (Windows 7, 8.1 and 10) are safe with the latest updates installed.
On the other hand, the Windows XP, Windows Server 2003, and Windows 8 are no longer supported and have not received the most recent updates, so Microsoft has decided to publish this emergency update, given the scale of the attack.
"We also know that some of our clients are running versions of Windows that no longer receive mainstream support. This means that these customers will not have received the aforementioned security update that was released in March. "Given the potential impact on customers and their businesses, we have decided to release the security update for custom supported platforms, Windows XP, Windows 8 and Windows Server 2003," said Microsoft.
"This decision was based on an assessment of the situation, keeping in mind the principle of protecting the ecosystem of maw customers as a whole."
The company goes on to say that some attacks use phishing tactics with malicious attachments, so users should avoid opening these files, especially if they come from unreliable or unknown sources.
