APT36 has pivoted from off-the-shelf malware to "vibeware", an AI-driven development model that produces a high-volume, mediocre mass of implants.

Using niche languages like Nim, Zig, and Crystal, the actor seeks to evade standard detection engines while leveraging trusted cloud services, including Slack, Discord, Supabase, and Google Sheets, for command and control. #AISecurity

🐀 AsyncRAT is an open-source .NET remote access trojan (RAT) with extensive credential theft capabilities and persistent access mechanisms. Our latest research uncovers methods for detecting AsyncRAT threats and analyzes what these indicators tell us about how they’re configured and deployed.

🌐 For one, our findings show decentralized hosting that favors low-cost, abuse-tolerant VPS providers, with a lack of customization among deployments. This indicates that these are likely highly commoditized and resource-efficient attack campaigns. The upside? These patterns provide powerful detection pivots.

The Criminal Supply Chain

Three interconnected threat actors comprise a complete attack supply chain:

The Scanner: A distributed bot infrastructure systematically probes the internet for exposed AI endpoints. Every exposed Ollama instance, every unauthenticated vLLM server, every accessible MCP endpoint gets cataloged.

The Validator: Once scanners identify targets, infrastructure tied to silver./inc validates the endpoints through API testing. During a concentrated operational window, the attacker tested placeholder API keys, enumerated model capabilities, and assessed response quality.

The Marketplace: silver./inc operates as "The Unified LLM API Gateway"—a commercial marketplace reselling discounted access to 30+ LLM providers without legitimate authorization. Hosted on bulletproof infrastructure in the Netherlands, the service markets on Discord and Telegram while accepting cryptocurrency and PayPal.

A full iOS zero-day exploit chain used in the wild against targets in Egypt. #Intellexa #Predator

Stage 1: Initial RCE via JSKit Framework (Safari WebKit Exploitation)Entry Point: The chain starts with a zero-day RCE vulnerability in Safari's WebKit rendering engine, patched by Apple as CVE-2023-41993 (a memory corruption issue in the JIT compiler).

Stage 2: Sandbox Escape and Kernel Privilege EscalationVulnerabilities Exploited: CVE-2023-41992: Kernel IPC use-after-free (sandbox escape + local privilege escalation, LPE).
CVE-2023-41991: Code-signing bypass (LPE).

Stage 3: Persistence and Surveillance Setup (PREYHUNTER Modules)Components: Divided into two modules—"watcher" and "helper"—deployed via the escalated privileges from Stage 2.
