I was going through some articles on various spam and phishing attacks today and came across one that made me wonder about protective measures. Specifically, I read about a consent-based attack that hijacks Microsoft accounts through the Azure CLI. It got me thinking: what steps can be taken to safeguard against such threats? Can we set up a conditional access policy to prevent these kinds of attacks? Also, is there a resource or wiki that lists known threats and effective strategies to counter them?

The phishing process is pretty standard—it's about convincing users to paste a URL into a malicious page, which grants the attacker access through the Azure CLI OAuth app. This doesn't seem much different from typical phishing scenarios.

People can be careless, that’s for sure. But I'm aiming to be proactive about security and create measures that will help!
It's crucial that only admin accounts have the permissions needed for such an attack to succeed. If regular users have admin access and can create OAuth apps via the Graph API, that's a major security risk. It might be worth bringing in a cybersecurity expert for an audit.
You can create a conditional access policy that restricts non-admin users from accessing the Graph API, which should help prevent this issue. It’s definitely worth looking into!
Actually, it’s an OAuth consent request, and you should have the settings configured for Admin Only. This kind of OAuth abuse has been happening for a while, so it’s important to stay on top of it.
I don’t think this attack vector is related to the User Account Control prompt.
