A sophisticated infection chain leverages PowerShell loaders to deliver encrypted NetSupport client payloads concealed within fake MP4 files. The malicious MP4 containers appear valid to basic file-type checks but contain 6.5 MB of encrypted data in ISO Base Media File Format uuid extension boxes rather than playable video content. The attack begins with PowerShell delivered via Cloudflare-fronted infrastructure, performing environment checks before retrieving the carrier file. A secondary script parses the MP4 structure, extracts and decrypts an embedded 16.8 MB PowerShell payload, then deploys NetSupport Manager with silent operation configured. Infrastructure spans 40 live endpoints across six autonomous systems, primarily in Frankfurt and Los Angeles, with command-and-control gateways registered 77 seconds apart. The toolkit employs Russian-language business site decoys and rotates carriers frequently without backward compatibility.

Chaos RAT is an open-source remote administration tool written in Golang that has evolved since 2022 to support both Linux and Windows platforms. A critical vulnerability identified as CVE-2024-30850 exists in its web control panel, allowing remote code execution on the server. Although currently limited in usage, Chaos RAT's low detection profile enables threat actors to perform espionage, data exfiltration, and maintain persistent access. The malware employs multiple techniques including privilege escalation, persistence, and command and control communications. Organizations should prioritize patching the vulnerable control panel, restrict access to administrative interfaces, and monitor for indicators of compromise. The threat is assessed as high severity due to its potential impact and ease of exploitation without user interaction. Patch status is not confirmed; no official fix or patch links are provided. The affected platforms include Linux and Windows systems. No specific countries are identified as targeted, but those with significant Linux and Windows server use and strategic geopolitical interests may be at higher risk.
