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.

    So if my understanding is correct, to be exploited the attacker would already need to be in a position to intercept your traffic, but this means when they do they can effectively impersonate anyone.

    This could actually be an interesting attack vector for hacking IOT devices. If you control the DNS server the device connects to you can get it to trust literally anything.

      Wasn’t the Gamer’s Nexus video on LG spy TVs, saying that the telemetry traffic is protected by SSL and thus they couldn’t figure out exactly what was sent? Would they be able to use the leaked keys to decrypt the traffic?

        That should be possible yes, depending on how those TVs handle their cert stores.

          Thanks, I wasn’t sure if it mattered that the leaked keys in this case were for intermediate certs and not root certs (afaik)
