CVE-2020-0601 | Windows CryptoAPI Spoofing Vulnerability

Microsoft announced on its January patch Tuesday (14/01/2020) that a new exploit has been identified and resolved. 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. Fortunately, this is resolved in the January 2020 Cumulative patch released by Microsoft for Windows 10 and Windows Server 2016 & 2019.
