If attacker controlled data is viewed in Cloudshell it could have led to code execution. This exact same issue existed in Azure previously.
A vulnerability in the Azure Linux VM extension mechanism allowed an unprivileged user to leak any Azure VM extension’s private data. An attacker could have abused this to gain credentials for the VM itself as well as credentials for extensions associated with the VM. Paired with the design of the VMAccess extension (an official Azure extension for managing VM credentials), this could have been used to achieve privilege escalation, as an unprivileged attacker would have been able to elevate the…
Hackers always try to cover up their tracks. In this blog, we step through layers of obfuscation to uncover the real intent of a .NET malware sample.

In cybersecurity, education and training are the key to winning. Read our blog to learn how you can grow your skills through continuous security education.
An attacker could gain root privileges on their Azure Cloud Shell container, escape from the container, and then gain root privileges on the underlying node, the root cause being an insecure kubelet port (10250), among other cluster misconfigurations. Once they could access the node filesystem, an attacker could extract kubelet API credentials which allowed listing all pods and nodes in the cluster, including those belonging to other tenants. Moreover, an attacker could bypass RBAC policies in …
To avoid detection, hackers often turn a system’s own tools against itself. Here, we examine a malicious payload that was executed using PowerShell.

When the compute API is enabled on a GCP Project, the default compute account is created. This account gets the primitive role Editor assigned by default, which allows for a wide variety of privilege excalation and resource abuse in the project. Especially, all new VMs created inherit this permissions by default. This issue is arguably a technical decision by GCP, but the documents advise customers to undo this.
