Using this access, I gained admin permissions to: ☸️ SAP AI Core’s K8s cluster 🐳 SAP’s container registries 🐸 SAP’s Artifactory server Allowing attackers to access: 📄 Internal logs 📁 Private customer files 🔑 Customers’ cloud secrets And more!

With unrestricted access to SAP’s internal network, I started searching for interesting internal services. I quickly found a Grafana Loki server, several EFS file shares, and a Helm server. They all had one thing in common – they were fully accessible without authentication 🫠

I started reading the traffic rules set by Istio. All network traffic was redirected to the proxy. Except… traffic by UID 1337? 🤨 Although I couldn’t be root, setting my UID to 1337 was still allowed. So that’s what I did. Crazily enough… it worked! 🤯

SAP AI Core allowed me to run AI training procedures – but with heavy restrictions. 🚫 I couldn’t run as root 🚫 Interesting permissions were removed 🚫 Access to the internal network was blocked by an @IstioMesh firewall So I wondered – how does this firewall actually work?

We discovered that by uploading a malicious AI model to @Replicate, a leading AI-as-a-Service platform, we could read and modify prompts of other customers 🤯 Here is exactly how we did it 🧵⬇️

I hacked into a @Bing CMS that allowed me to alter search results and take over millions of @Office365 accounts. How did I do it? Well, it all started with a simple click in @Azure… 👀 This is the story of #BingBang 🧵⬇️

Hi @BlackHatEvents - I was shocked to discover that one of your Cyber Security Trainer and Review Board Members is also an antisemitic, a terror supporter who publicly denies Hamas Terror acts. Please remove @Voulnet from his role immediately!

For more details about this exposure, as well as a breakdown of potential risks and security recommendations when using SAS, read our technical blog here >>

Wiz Research found a data exposure incident on Microsoft’s AI GitHub repository, including over 30,000 internal Microsoft Teams messages – all caused by one misconfigured SAS token

How can you avoid this? 🚨 Avoid using Account SAS for external sharing. Azure offers more secure alternatives, such as Service SAS with Stored Access Policy (for long-term sharing), or User Delegation SAS (for short-lived access).

Why did this happen? 🧐 Account SAS tokens are created offline, with no limit on their expiry or scope. They aren’t managed within the Azure portal, and they’re also difficult to revoke. These features help easy content sharing, but they can also serve as dangerous pitfalls.
