Long story short it's being called the "Windows 10 validation bug" which is exactly what i've talked about on here before. I'm not trying to take credit for inspiring the attack however it's pretty clear and obvious how it happens.
I theorized a while back that you could break the certification of a windows update or any program update with an infected file, even as far as in some cases - having someones IP address and knowing what programs they run, pinging an application for an update and infecting the update with a malicious file.
While this NSA report is specifically for Windows 10 as the base OS itself, it's still a heavy possibility to do this through other applications you have installed on your machine. Always be careful of what you install and allow automatic updates for.

If you want it dumbed down a bit - they put out this also which touches on other applications being used in this way.

For those wondering, here is one example of the many threads I made on it - this one is about 4 months ago.

Quote:NSA has discovered a critical vulnerability (CVE-2020-0601) affecting Microsoft Windows®1 cryptographic functionality.
The certificate validation vulnerability allows an attacker to undermine how Windows verifies cryptographic trust and can
enable remote code execution. The vulnerability affects Windows 10 and Windows Server 2016/2019 as well as
applications that rely on Windows for trust functionality. Exploitation of the vulnerability allows attackers to defeat trusted
network connections and deliver executable code while appearing as legitimately trusted entities. Examples where
validation of trust may be impacted include
If you want it dumbed down a bit - they put out this also which touches on other applications being used in this way.
Quote:CVE-2020-0601 is a serious vulnerability, because it can be exploited to undermine Public Key Infrastructure (PKI) trust. PKI is a set of mechanisms that home users, businesses, and governments rely upon in a wide variety of ways. The vulnerability permits an attacker to craft PKI certificates to spoof trusted identifies, such as individuals, web sites, software companies, service providers, or others. Using a forged certificate, the attacker can (under certain conditions) gain the trust of users or services on vulnerable systems, and leverage that trust to compromise them.

Quote:I'm not quite sure how this would play out yet as I assume most paths are clearly patched.
Say a program like Chrome is installed and we can see that through a man in the middle attack (headers).
We see an update for the browser has been released or just about to be released that day.
What if we grab that certificate for the browser update and craft a malicious replacement for the man in the middle attack.
Same would apply for Windows or Adobe applications - surely there must be something that's vulnerable through that. I haven't personally seen anyone doing network exploitation through application updates before.
