In May, Microsoft released a security update to Windows XP and Windows 2003, which had been terminated, to fix a vulnerability that allegedly spread malicious programs as quickly as the WannaCry worm. The vulnerability, known as BlueKeep, is located in Remote Desktop Services.
Microsoft and the NSA have issued warnings for users of Windows XP and other affected versions to patch them in a timely manner. In addition to XP, Windows 7, Windows Server 2008 R2, and Windows Server 2008 also have this vulnerability.
Security researchers now report that the BlueKeep attack is ongoing. Attackers are now primarily exploiting the vulnerability to exploit digital currencies and may use them for other malicious purposes in the future. To date, there are still 700,000 Windows systems that have not been patched.
