Veracrypt also doesn’t recommend using encryption that relies on TPMs
Some encryption programs use TPM to prevent attacks. Will VeraCrypt use it too?
No. Those programs use TPM to protect against attacks that require the attacker to have administrator privileges, or physical access to the computer, and the attacker needs you to use the computer after such an access. However, if any of these conditions is met, it is actually impossible to secure the computer (see below) and, therefore, you must stop using it (instead of relying on TPM).
If the attacker has administrator privileges, he can, for example, reset the TPM, capture the content of RAM (containing master keys) or content of files stored on mounted VeraCrypt volumes (decrypted on the fly), which can then be sent to the attacker over the Internet or saved to an unencrypted local drive (from which the attacker might be able to read it later, when he gains physical access to the computer).
When using an external TPM. Which next to no one does.
Watch the video. It just means external to the CPU, not an external device.
They demo the attack on a Lenovo laptop in the first minute of the video.
Edit: nm I just realized that was a 10 year old laptop and they’re in all the modern procs. I’m a lot less impressed now.
Sounds like intel has external and amd internal with their ftpm?
Many systems still use discrete tpms. Just because the CPU has a virtual tpm function doesn’t mean it’s used
fTPM has a bug, don’t know if it’s fixed

Let’s assume the attackers were law enforcers
This has been fixed for a while now

It’s fairly common in business devices before 8th gen Intel.

The MSI mini-PC-s for office/business use have separate TPM modules on their mobos. I wouldn’t be surprised if other mfg-s do this too.
