- Socially engineer an employee to get on their VPN (could have been prevented with webauthn / hardware 2fa)

- Once on VPN, scan their intranet and find a network share

- Network share has powershell scripts with admin credentials for their PAM vendor, Thycotic

- From there can get full access to all systems

Someone forgot the “and then watch that basket” part about putting all your eggs in one.

This is gross incompetence.

Thycotic and Centrify have been rolled up into Delinea fwiw.

Pour one out for our fellow sys admins & security teams that are going to be working late into the night. They took down their Slack so I wonder what out-of-band comma they’re using.

EDIT: Comms not comma. I'll leave the typo because I LOVE bombcar's comment about the semicolon. Confused at first, but I smiled

I think it's worth repeating: at this point, MFA that is not based on Webauthn (https://webauthn.guide/#about-webauthn) should be considered dangerously insecure. Uber almost certainly enforces MFA for remote access; I strongly suspect we'll end up hearing that it was successfully provided during the authentication step (update: screenshots on Twitter appear to confirm this). As we saw in the case of the 0ktapus campaign, a sufficiently-skilled attacker will simply proxy the MFA calls to the real identity provider in real-time, the user none the wiser.

Webauthn, however, binds the authenticator to the domain and port, and requires https as the scheme. If a user gets phished, they cannot be compromised: the phisher's domain will not match and any Webauthn authentication challenge would fail.

So if your workplace is letting you authenticate with SMS codes, push notifications to an app, or 6-digit codes generated by an authenticator app/hardware device, you need to start banging on pots and pans up your reporting chain to get your security team the support they need to make Webauthn + FIDO2 hardware tokens or Webauthn + Mac Touch ID happen.

I would be shocked if they didn’t issue all employees YubiKeys.

Probably a semicolon!

(I’d assume going to text messaging to set something up, which is why you should know enough about your immediate coworkers to verify their identity via non-public information.)
