It also not the only conclusion left - it is just you jumping to the least probable explanation without any evidence.

The 'both were just signed' argument fails to address the structural anomalies. If Microsoft signed both, why does the malware use RSA-2048 while the official binary uses RSA-4096?. Furthermore, the malware carries a compilation timestamp from the year 2097, an APT technique to evade security filters.
We aren't just seeing 'two signed files'; we are seeing a malicious binary (verified with sandbox escape and session theft) that shouldn't exist in Microsoft's signing pipeline, yet it carries a valid signature and was delivered via a zero-click attack from an official CDN. This points directly to a compromise of the trust infrastructure (Key compromise, CA breach, or verification bypass), not a routine signing event
Please use the original title:
"SHA-2 and SHA-3 Are Broken Evidence of Cryptographic Signature Forgery with Valid Microsoft Certificates on Modified Binaries OMEGA INFINITY" (you probably have to cut it to make it fit in the 80 char limit.)
