Do they?

The only anecdotal thing I've seen is we hired a vendor to do a pentest a few years ago, and they setup some stuff in an AWS account and that account got totally yeeted out of existence by AWS if memory serves.

You should not be conducting unauthorized penetration tests against third party infrastructure providers without permission. They have processes and systems and usually just wants a heads up of what you plan to test and t the duration / timestamps.

Cuz otherwise you look like a threat actor.

That’s assuming your vendor was pentesting AWS systems. If you meant you hired a vendor to pentest your own systems on AWS, that’s of course a totally different matter.

Sorry for being unclear, the vendor was attacking our organization only, and any other company was expressly forbidden in the contract. As I recall it was a fake SSO sign-in page to collect credentials that they would try and social engineer our employees with.

At a minimum you should contact AWS before you launch a phishing page as a test that targets AWS customers.

I understood it as a phishing page imitating their own system, targeting their own employees. Nothing related to AWS, except for being hosted there.

I’m fairly certain you are supposed to contact any vendor before attempting to penetrate hosts with authorization, not the other way around.

Having done this for both Azure and AWS, there's a specific ticket that needs to be filed with each provider that documents the scope of your pen test, where you're coming from, and a time frame over which you're doing it (which ISTR was "not more than 24 hours")

Responding to an unknown security tester like that is a selling point, not a cautionary tale

Yup, I thought it was great. Although one concern I always had in the back of my mind was where is the line drawn. Such as if an adversary gains access to one of my orgs accounts and does something similar, do we get 100% taken out.

If a vendor doesn't know the basics about pentesting open infra and can't be bothered to look up terms of use sounds like they know ssh-it about fsck

They better do. What is google doing?
