The recent discovery of malicious npm packages targeting Solana private keys highlights the ever-present threat to developers and users in the cryptocurrency ecosystem. These packages, masquerading as legitimate tools, employed clever exfiltration techniques, including leveraging Gmail as a covert communication channel, to steal sensitive information and drain victims’ wallets. This blog post will dissect the tactics used in these attacks, providing engineers with crucial insights to enhance their security practices.

Google Kubernetes Engine (GKE) is a popular container orchestration platform that allows developers to deploy and manage containerized applications at scale. However, a recent security vulnerability has been discovered in GKE that could allow attackers to gain access to clusters and steal data or launch denial-of-service attacks.

The vulnerability is caused by a misunderstanding about the system:authenticated group, which includes any Google account with a valid login. This group can be assigned overly permissive roles, such as cluster-admin, which gives attackers full control over a GKE cluster.
