Astonishingly, the private keys were 4, 56, 66, 115, 155, 156, 230, 237.
exploiting compromised certificates requires an active adversary-in-the-middle attack, meaning the attacker must act as a proxy between two TLS parties and receive encrypted traffic, decrypt it, reencrypt it, and send it to the other party. Such capabilities, in some cases, are usually limited to only the most well-resourced attackers. People with control of a local network—at a coffee shop, university, or other organization—face much less of a challenge.

how would I get away from intermediary CAs? i also don’t see indications eMurdha refused to fix the vulnerability when reported
I didn’t say it’s easy. It’s just the only way. First step would be removing them from the list of trusted CAs installed on your devices.
And of course, security flaws chain together. So if you don’t trust Microsoft office, you basically can’t trust any commercial product in existence.
But at least you can avoid being a direct customer of them, even if you’re still an indirect one.
