1/ We recently had an interesting #Azure case where the TA, instead of creating a new Inbox Rule, added email addresses of interest to the list of blocked senders and domains.

The incoming emails will get flagged as spam and moved to the Junk email folder. 📂

Knowing Azure Monitor is a must for many roles. But are there other monitoring services you should learn?

There’s monitoring for security, networks, SQL, and more. Some within Azure Monitor, others are elsewhere.

For apps, one you should know is Application Insights. Image
App Insights can help you:
🧠 Understand usage trends 
🧠 Monitor performance live
🧠 Map application components

You can even use AI/ML to perform "smart monitoring" to analyze and detect failures and anomalies in your app proactively.
🧙‍♂️If your app is running in Azure, you can enable this automagically.

There's an approach called autoinstrumentation which works on Azure App Service, Azure Functions, and VMs.

As long as you use a supported language, you can gather telemetry without modifying code.

📚 Excellent article on #Phishing techniques targeting #O365 and #Azure🎣 Traditional phishing, device-code authentication, illicit consent grant attacks... it is not easy to make it simple on this topic, and it's the case here! riskinsight-wavestone.com/en/2023/03/ill… Image
1️⃣ Obviously, the traditional phishing attack is simple to implement in the absence of multi-factor authent 🔐 We know what to do!
2️⃣ More tricky, device-code authent attack: the attacker’s objective is to get the victim to fill in his device code on the Ms devicelogin page🔥
3️⃣ Conditional access policies can be used to prohibit suspicious connections from devices not under the control of the company👍
4️⃣ The illicit consent grant attack relies on the ability of an attacker to create an app that requires permission to be granted 💣

This week I added 5 new functions to #BARK. A quick thread explaining each one with examples:
Get-ServicePrincipalOwner

List the current owner(s) of a specified #Azure AD Service Principal.

Example:
New-ServicePrincipalOwner

Add a new owner to an AAD Service Principal. Owners can add credentials to SPs and then auth as them.

Example:

Azure App Service Web Apps are yet another #Azure service that supports managed identity assignments.

Here's how attackers can use #BARK to abuse those assignments: Image
There are at least 3 ways to achieve code execution on an Azure App Service Web App ("Azure Web App" from here on) instance:

1. The Kudu shell execution API endpoints
2. Poison deployment to include a web shell in the app
3. Find a cmd execution vulnerability in the deployed app
We'll focus on #1 - abusing the built-in Kudu shell execution endpoints.

This is the feature the Azure GUI uses as its "Debug Console" and is documented here: github.com/projectkudu/ku…

@kfosaaen discussed this in his August 2020 blog post here: netspi.com/blog/technical… Image

How do you connect different networks in #Azure? The primary was is through VNET peering. In this thread, I'm going to do a quick breakdown to help you understand this cloud magic! Image
Azure VNET Peering allows you to connect two Azure virtual networks (VNETs) creating a secure and fast connection between the two.

This allows communication between resources in the two VNETs without going through the public internet but instead over the Microsoft backbone!
There are two types of VNET peering - "Global VNET Peering" & "Regional VNET Peering." Global VNET Peering enables connectivity between virtual networks in different regions. ImageImage

1/ #Azure In a recent case, the TA was able to compromise the user despite MFA (MFA fatigue).

After logging in, the attacker registered another mobile number as "Alternate Mobile Phone Call".

In the audit logs, we see this event within "Authentication Methods":

🧵 #DFIR
2/ The audit logs are a goldmine for finding suspicious behavior in an Azure tenant.

If we filter by "Core Directory", "UserManagement" and "Update user" ..
3/ .. we also see the ModifiedProperties (the modifications done by the attacker).

Notice, the primary Phone Number is a Swiss mobile phone (+41), and the attacker added a number from the United Arab Emirates (+971).

Suspicious? You bet!

Role Based Access Control (RBAC) is arguably one of the biggest headaches for engineers in a Kubernetes cluster.

However, there are certain ways to make it far easier.

A thread 🧵
Before jumping into that, let's talk about RBAC.

When you're trying to access a Kubernetes cluster and perform an action, it takes two roles:

- Authentication
- Authorization
Authentication gets you into the cluster. Authorization allows you to perform a certain action in a cluster.

How a simple web-app assessment lead to complete #AzureAd tenant takeover 🤯
🧵 👇
#Azure #AzureKubernetesService #aks #Kubernetes #KubernetesSecurity #k8s #bugbounty #bugbountytips #bugbountytip #DevSecOps
1. Poorly-designed file upload functionality lead to RCE
2. Turned out the app was running in a container managed by #AzureKubernetesService (#AKS)
3. #Container was mounting a service account with permissions to deploy #pods in the same namespace
4. I deployed a new pod with hostPath root volume. Deployment was not blocked by any security policy. #Pod got deployed
5. I exec-ed into the pod's #container and escaped it through its hostPath volume. #privesc to the #AKS node succeeded!

[1/15] Die News rund um #FLR/#SGB und @FlareNetworks reißen nicht ab! Soeben noch über #FIP.01 geschrieben, postet (FlareN.) $FLR / $SGB jetzt über die neue Partnerschaft mit @GoogleCloudTech

Meine kurze Einschätzung und ein Blick auf den GoogleCloud Blogeintrag in einem 🧵👇
[2/15] Fangen wir damit an die Größe der "#Cloud" einmal zu quantifizieren und in Zahlen einzufangen:

• Welche Player sind auf dem Markt?
• Welche Infra. hat wieviel % vom Kuchen?
• Wie Groß ist der Kuchen und wird er noch größer?
• Was wird angeboten? Source: https://cdn.statcdn...
[3/15] 👉 Wer sitzt am Tisch?

Wenn wir ganz ehrlich sind gibt es nur 3 namenhafte Anbieter, die heute ihre Anwendung finden.

Dazu gehören:
#AWS (Web/Email-Server, Dev-Tools, ML, Container)
#MS #Azure (Interne Firmen- u. Netzwerkinfra.)
#GCP (VM, AI, Storage, IaaS) Source: https://intellipaat...

1/ Perhaps a lesser known "feature" of Microsoft Authenticator, but the diagnostic data can be very helpful in investigating a compromised #Azure account where MFA is enabled but the user claims not to have confirmed the MFA Consent Prompt. 🧵
2/ You will find the diagnostic data here:

Authenticator App
▪️ Burger Menu
▪️ Send feedback
▪️ Having trouble?
▪️ View diagnostic data

Click "Copy all" and send the text via mail or other ways to your analysis device. Image
3/ When logging into an MFA protected (the second factor is the Consent Prompt) account, we see the following entries (abbreviated) in the Authenticator diagnostic data:

Do you need a #multicloud #strategy? Most likely, not. Just use one cloud that fits your needs.

The chances are that your project is multi-#cloud, anyway. There are nuances, of course.

One is TRAFFIC. The cost can go up depending on the path it follows.

A thread 👇🧵

1/6 Image
The bigger the company, the bigger the chance that you are already using multiple #clouds. Generic public clouds (#AWS, #GCP, #Azure), private clouds (#VMWare, #Nutanix), and specialized clouds (#Cloudflare, #Vercel) can all be combined together for the benefit of your org.

2/6
If you have just a few GBs of traffic a month, then this would most likely not have a big impact on your #cloud #costs. But if you have more than a few GBs per hour, a #multicloud setup may bring you some surprises.

#Azure Managed Identity assignments are "secure by default."

Dangerous attack paths can emerge around these assignments.

Here's those attack paths emerge, how attackers abuse them, and how defenders can eliminate them: 🧵
First we should understand what Managed Identities are. I think the best way is to understand the problem they are designed to solve.

We have a great recent example of this problem from the alleged Uber breach, where a PowerShell script may have been storing plain text creds:
This problem is not new and not surprising to many people:
