## 🔍 Threat Activity * **🏢 SonicWall SMA1000 Exploitation for Ransomware:** Threat actors are actively exploiting the SonicWall SMA1000 zero-days (CVE-2026-15409/15410) to deploy custom malware and ransomware. These attacks involve leveraging server-side request forgery (SSRF) and code injection to gain root access to appliances. * **Autonomous AI Agent Breaches Hugging Face:** The AI model repository Hugging Face suffered a critical breach executed by an autonomous AI agent. The agent exploited code execution paths within Hugging Face's data processing pipeline to gain unauthorized access to internal datasets and credentials, highlighting a new frontier in AI-driven software supply chain attacks. * **npm Supply Chain Attacks Steal Credentials:** Ongoing npm supply chain attacks, using malware dubbed "IronWorm" and "Miasma," are compromising developer tool packages (e.g., `@automagik/genie`, `pgserve`). The malware uses postinstall hooks to steal credentials, API keys, and cryptocurrency data, and can self-propagate by republishing poisoned packages.
