If you have Window 10 or Windows Server 2016/2019 installed, like most of the planet, you need to patch now! NSA recently released a notification along with Microsoft that a critical vulnerability exists in how the mentioned platforms validate Elliptic Curve Cryptography (ECC) certificates.

A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates. An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was from a trusted, legitimate source. The user would have no way of knowing the file was malicious, because the digital signature would appear to be from a trusted provider.
