The private key of an SSL certificate that belongs to a brazilian bank has been leaked. What are the risks?
Some background first: last week, some data from a Brazilian bank named Inter was rumored to have been leaked. That included personal data, documents, transaction logs, credit card passwords, everything a bank could possibly have, including the certificate's private key. The bank denied everything.Two days ago some guy showed up on r/brasil claiming he obtained the private key from somewhere public, which he did not disclose. Someone suggested that he signed a message to prove he had it, which he successfully did and can be verified here. It's worth noting that the certificate in question had been replaced on the website in march but did not expire and was still valid.The obvious reaction to this would be for the bank to ask for the revocation to the Certificate Authority, in this case, Go Daddy. The surprising thing is: it's been more than 48 hours since this went public and the certificate has not been revoked yet. The bank is dead silent about this.Considering the keys have fallen in malicious hands which intends to do man-in-the-middle attacks, what are the possible attack vectors from which this is possible? I know DNS spoofing is a possibility. Are there other types of attacks which can originate from this? Some relatives have bank accounts there and are worried. Thanks in advance.

How does ROCA affect Windows secure boot?
I've been doing some research on the Infineon vulnerability known as ROCA over the last few days. As I understand it, the vulnerability is present when a TPM running vulnerable firmware generates an RSA key. At that point, the public key can be used to derive the private key. My question, however, is how this affects secure boot in current versions of Windows. As far as I know, the TPM does not perform any key generation for secure boot and the secure boot keys are managed by Microsoft. Therefor, as far as the end user is concerned, ROCA isn't really relevant in the context of secure boot. Is this correct?

Google Duplex Abuse
With all great technology comes the dark side. The demo was pretty impressive but I could imagine this being used for mass scale nefarious activities. A call spammer was just slapped with a big fine for a pretty simple recorded message. Imagine the level of sophistication these attacks could now leverage using something like Duplex for their robo calls.Google mentioned they would have a notification system to ensure the receiver knows the call is being recorded and their interacting with AI but if this becomes adopted for consumer services most people will become numb to that warning.Thoughts? :)

Disclosing a security issue to the public
A major hosting company has a security issue that, in certain circumstances, leaves it's customer's data on it's filesystem even after the data should have been deleted. I found a way to access that "deleted" data, by mistake. I reported the issue via email, but considering the "we don't keep the data" answer, I guess that my report was not taken seriously. Should I keep bugging them or just make the issue public?
