Extending the value of network evidence: Introducing Performance and Asset Visibility

Every packet flowing through a Corelight sensor contains both security-relevant data and performance-relevant data. Until now, Corelight has focused exclusively on extracting security value from network traffic: connection logs, protocol analysis, and threat detections. But the same traffic that reveals lateral movement also reveals TCP latency. The same DNS queries that surface potential C2 channels also reveal resolution timing.

Corelight Sensor v29.1 release highlights: Network evidence powers network operations

Corelight Sensor v29.1 and Fleet Manager v29.1.1 fundamentally expand what a Corelight Sensor delivers. The release turns existing network evidence into a shared source of truth for SecOps, NetOps, triage, and forensic investigation.

The Deep Dive: Kroll's Analysis of the GARUDA C2 Malware

Kroll identified a cross-platform malware framework, dubbed GARUDA C2, that uses public code-hosting platforms like GitHub for staging, redundancy and command distribution across Windows, macOS and Linux. Analysis links the campaign to an India-based operator supported by Hindi-language development artifacts, build logs, infrastructure indicators and evidence suggesting use of a locally hosted large language model (LLM) to accelerate malware development.

VMware ESXi Networking Concepts

For connecting physical servers and computers to a network, you need physical network adapters, switches, and routers. With virtual machines, virtual network concepts are used for communication between the different components of an infrastructure. The proper configuration of ESXi networking on a host is critically important to the configuration of any ESXi environment. Generally, ESXi host networks include storage, vMotion, VM, and management networks.
