How does this work with more complex authentication schemes, like AWS?

[solatic]

AWS has a more powerful abstraction already, where you can condition permissions such that they are only granted when the request comes from a certain VPC or IP address (i.e. VPN exit). Malware thus exfiltrated real credentials, but they'll be worthless.

I'm not prepared to say which abstraction is more powerful but I do think it's pretty funny to stack a non-exfiltratable credential up against AWS given how the IMDS works. IMDS was the motivation for machine-locked tokens for us.
