Almost one million older Windows devices are still vulnerable to the BlueKeep security flaw even after Microsoft released a security patch to address the vulnerability.
The vulnerability, known as CVE-2019-0708, affects Windows Remote Desktop Services (RDS) and Microsoft has already addressed it with its May 2019 Patch Tuesday update.
The BlueKeep security flaw, which has been described as wormable, can be utilized by malware to spread in a similar way to how the WannaCry ransomware did back in 2017 through the EternalBlue exploit.
