What is the opening discussion about the podcast and its sponsors?
Welcome to episode three hundred and fifty three of the Defensive Security Podcast. My name is Jerry Bell and join me today as always. Is Mr. Andrew Kellett?
Good afternoon, sir. How are you?
I'm great now that I figured out how to operate my screen share, so
Yeah, how are you? I look, I get it. Over the age of thirty, these computer things just aren't meant for us anymore. We just put us out to pasture.
That's right. Absolutely.
I'm uh trying to stay busy, you know, doing a little bit of consulting here and there, trying to find some cool projects to work on. So Enjoying my underemployment period, as it were.
Good, good. So a uh quick thank you to our Patreon sponsors. Thank you so much for your continued support. And if you do want to support us, you can do so on our Patreon site. It's patreon.com slash defensive sec. And if you do
Want to thank all our amazing donors. Sorry, just wanted Echo that. Carry on.
Thank you. If you do if you do become a donor, you will get episodes A week early and we are we are talking about some some other things for uh Other other spiffs for the The donors. So we'll we're we're working on that. Slowly.
I did talk Jerry out of sending everybody socks, like used worn socks as a thank you. I told him that was a bad idea.
There was that. And a quick reminder that the thoughts and opinions we have and express on the show are ours and not those of our employers, past, present or future. All right, getting into some stories. The first one comes from Security Week and the title here is Uh Massive passwords break campaign targeting Azure CLI. So um this is an interesting one. Uh I think this was found by one of the one of the security vendors. So, you know, the more more blog spam. But I thought it was interesting because uh even though it was a f you know, f fairly they talk about eighty one million login attempts So like On my Mastodon server, I think I get that like every week. So that's not a not a you know magical thing. What is interesting though is that
Uh in spite of the relatively sophisticated options that you have in in uh In Azure. Quite a few there were quite a few hits, so seventy eight accounts were compromised. And and this was just through basically brute forcing. What they um you know, what they were doing here was using not the normal authentication method. They were using an OAuth Path that uh apparently I I I don't understand this fully. To be perfectly honest. But uh the OAuth there's an OAuth endpoint where you could stuff a username and password, not an OAuth token, and it would not um because because it's kind of a f an abnormal path, it doesn't actually have the ability to prop to prompt for MFA. And so they got logic seventy eight times.
Yeah, it'll just kick back a token to you. And to be fair, uh this particular functionality has been deprecated. It should It should be turned off because it's got this note weakness. It's it's an older version, it's not in Uh Newer versions of the O standard, but Uh yeah. But who would do and and I think isn't brute force if they were doing password spray, does this mean more that they were using leaked passwordless versus like a brute force attack type?
Yes, yes. That's my that's my expectation.
Iteratively checking. A, B, C, D, E, you know, as opposed to password spray where they download a bunch of passwords and assume somebody's reused.
I don't think um I I don't think that online password attacks are are often done with brute forces. I think I think pa brute force password attacks I think are primarily relegated to like instances where you have a a hash and you're using a You know, some GPUs. So when I say root forcing uh I'm I'm probably not accurate in my description here. But yeah, you're right. They're they're They're using captured credentials that came from other breaches or Uh info stealers and stuff like that.
What I did find interesting, um Was that they had a number of customers Who had MFA turned on? and we already talked talked about that didn't cover this particular OAuth workflow. But then they also found customers who had MFA turned up but not configured fully or had gaps in their MFA settings or
