Today, Microsoft released patch for CVE-2020-0601, a vulnerability in windows “crypt32.dll” component that could allow attackers to perform spoofing attacks. This was discovered and reported by National Security Agency (NSA) Researchers. The vulnerability affects Windows 10 and Windows Server 2016/2019 systems.
This is a serious vulnerability and patches should be applied immediately. An attacker could exploit this vulnerability by using a spoofed code-signing certificate, meaning an attacker could let you download and install malware that pretended to be something legit, such as software updates, due to the spoofed digital signature.
