Android adds Intrusion Logging for forensic analysis

🔐 Intrusion Logging is an opt-in feature in Android's Advanced Protection Mode that records daily device and network activity to support forensic investigations. Developed with Amnesty International and Reporters Without Borders, it captures app launches, installs, network connections, USB file transfers, certificate changes, and lock/unlock events. Logs are end-to-end encrypted on the device, stored on Google servers for 12 months, and cannot be deleted early; users may download decrypted logs for external review but remain responsible for their security.

AI-Assisted Synthetic Attack Logs to Accelerate Detection

🔒 Microsoft researchers describe an AI-driven pipeline that translates attacker TTPs into realistic, structured security logs to accelerate detection engineering. The approach uses prompt engineering, collaborative agentic refinement, and data augmentation to generate semantically accurate telemetry (command lines, process ancestry, fields) without exposing sensitive customer data. Evaluation across multiple datasets shows agentic workflows and reasoning models notably improve recall and fidelity compared to prompt-only methods.

LLMjacking Risks: Securing Private AI Servers 2026

🔒 A hands-on April 2026 experiment shows how quickly attackers can target private AI servers: a Raspberry Pi honeypot posed as a high-performance stack (Ollama, LM Studio, AutoGPT, LangServe, text-gen-webui) and claimed a local Qwen3-Coder 30B instance plus RAG/MCP assets. Shodan discovered the server within three hours and, over a month, it logged 113,000+ requests from thousands of IPs with 23% probing AI capabilities. Observed tactics included fingerprinting endpoints like /v1/models and /.well-known/mcp.json and systematic hunts for exposed .env files, highlighting the importance of securing RAG, MCP and private AI deployments from day one.
