An AI agent hijacked by injected instructions uses neither: it acts through tools you already trust. What that means, honestly, for defence. https://hisnlabs.com/en/blog/electron-forensic-footprint-desktop-web-apps-egress-nightmare https://hisnlabs.com/en/blog/electron-forensic-footprint-desktop-web-apps-egress-nightmare Fri, 25 Sep 2026 00:00:00 GMT Electron bundles Chromium and Node.js into one process model. We unpacked a real, installed app’s archive to show what that means for security review and for network firewalls. https://hisnlabs.com/en/blog/encrypted-client-hello-ech-doh-blind-perimeter-firewalls https://hisnlabs.com/en/blog/encrypted-client-hello-ech-doh-blind-perimeter-firewalls Fri, 25 Sep 2026 00:00:00 GMT ECH (RFC 9849) hides the real hostname in the TLS handshake and DoH hides the DNS lookup. What that takes away from network firewalls, what it does not, and where visibility moves. https://hisnlabs.com/en/blog/fireai-fight-digital-distraction-schoolwork-mac https://hisnlabs.com/en/blog/fireai-fight-digital-distraction-schoolwork-mac Fri, 25 Sep 2026 00:00:00 GMT macOS already has real tools for a focused homework session: a clean desktop, Screen Time limits, scheduled Focus. Here is what each one actually does, and where they stop. https://hisnlabs.com/en/blog/jev-system-one-decision-models https://hisnlabs.com/en/blog/jev-system-one-decision-models Fri, 25 Sep 2026 00:00:00 GMT TypeSafe AI says its new model Jev answers in milliseconds with a typed, calibrated decision instead of a paragraph. Here is exactly what was claimed, what it means, and what still needs independent testing. https://hisnlabs.com/en/blog/local-llm-insecure-defaults-workstation-risk https://hisnlabs.com/en/blog/local-llm-insecure-defaults-workstation-risk Fri, 25 Sep 2026 00:00:00 GMT Local models feel private because nothing leaves for the cloud. Two real, patched vulnerabilities show what can still go wrong: an unauthenticated API, and an agent tricked by what it reads. https://hisnlabs.com/en/blog/mcp-blind-spot-local-tool-servers-prompt-driven-execution https://hisnlabs.com/en/blog/mcp-blind-spot-local-tool-servers-prompt-driven-execution Fri, 25 Sep 2026 00:00:00 GMT Anthropic’s Model Context Protocol lets AI agents call local tools.

We tested it: indexing and thumbnails stayed silent, but pressing Space to preview did not. https://hisnlabs.com/en/blog/slopsquatting-hallucinated-packages-coding-agents https://hisnlabs.com/en/blog/slopsquatting-hallucinated-packages-coding-agents Fri, 25 Sep 2026 00:00:00 GMT Code-generating models hallucinate package names at a measurable, sometimes predictable rate. Attackers register those names for real.
