A GUIDE TO KUBERNETES LOGS THAT ISN'T A VENDOR PITCH

This post explains logging in Kubernetes clusters using the 4Cs of cloud-native security framework. Code level logging can be achieved with sidecar pods. Cloud level logging relies on the specific cloud's services (for example CloudTrail on AWS). Container level logging isn't generally helpful for security. The post contains a deep dive into using and enabling AuditPolicy to collect logs at the cluster level.

TECHNICAL ANALYSIS OF THE LATEST VARIANT OF VALLEYRAT

The ValleyRAT malware uses a multi-stage process involving DLL sideloading, process injection, and shellcode execution to establish connections with a command-and-control server for downloading further malicious payloads. The malware utilizes encryption, decryption, and hashing algorithms to dynamically load and execute embedded DLLs, collect system information, and carry out specific actions based on the victim host's configuration. ValleyRAT conducts device fingerprinting to gather detailed information about the infected system, such as IP address, system uptime, hardware details, and user privileges, aiding in its malicious activities.
