Code Insight Expands to Cover Software Supply Chain Risks

🛡️ VirusTotal’s Code Insight now analyzes a broader set of software supply chain formats — including CRX, XPI, VSIX, Python WHL, NPM packages, and MCP protocol integrations. The tool inspects code logic to detect obfuscation, dynamic code fetching, credential theft, and remote command execution in extensions and packages. Recent findings include malicious Chrome and Firefox extensions, a deceptive VS Code extension, and compromised Python and NPM packages. This capability complements traditional signature- and ML-based classification by surfacing behavior-based risks.

Donut Shellcode: End-to-End Malware Analysis Tutorial

🧩 This Unit 42 tutorial walks analysts through a complete infection chain that uses Donut-generated shellcode, showing how a small position-independent routine computes its own base address via a call/pop/sub pattern and how that base drives payload offsets. The authors use step-by-step static and dynamic analysis with IDA Pro, x64dbg, dnSpy, and ProcessHacker to validate findings. Readers are shown common techniques such as dynamic API resolution, process injection, and AMSI bypass through memory patching, and are directed to a full PDF on the authors' GitHub for the complete walkthrough.

Malware Analysis on AWS: Building Secure Isolated Sandboxes

🔒 This AWS blog explains how security teams can run malware analysis in the cloud while complying with AWS policies and minimizing risk. It recommends an architecture that uses an isolated VPC with no internet egress, ephemeral EC2 detonation hosts accessed via AWS Systems Manager Session Manager, and secure S3 storage via VPC gateway endpoints with encryption. The post emphasizes strong IAM and SCP guardrails, immutable hosts, automated teardown, centralized logging, and monitoring with CloudTrail and GuardDuty to maintain visibility and lifecycle control.

CISA Releases Thorium: Scalable Malware Analysis Platform

🛡️ CISA, in partnership with Sandia National Laboratories, released Thorium, an automated, scalable malware and forensic analysis platform that consolidates commercial, custom, and open-source tools into unified, automated workflows. Thorium is configured to ingest over 10 million files per hour per permission group and schedule more than 1,700 jobs per second, enabling rapid, large-scale binary and artifact analysis while maintaining fast query performance. It scales on Kubernetes with ScyllaDB, supports Dockerized tools and VM/bare-metal integrations, and enforces strict group-based access controls along with tag and full-text filtering for results.

Unmasking AsyncRAT: Mapping Forks and Variants in the Wild

🛡️ ESET Research reviews the sprawling ecosystem of AsyncRAT, an open-source C# remote access trojan first published in 2019, and the many forks that have proliferated since. The post maps major families—most notably DcRat and VenomRAT—and outlines rapid identification techniques based on client configuration, embedded certificates, and behavior. It highlights uncommon plugins (USB spreaders, screamers, clipboard clippers, distributed brute modules) and stresses evolving obfuscation and evasion tactics.
