Running #Wasm components in a hypervisor and being able to tailor the interface between the hosted application and the trusted compute base enables platform builders unequaled ability to tune precisely the access provided to untrusted application code. opensource.microsoft.com/blog/2025/03/2…

davidjustice's tweet card. We're announcing the release of Hyperlight Wasm: a Hyperlight virtual machine “micro-guest” that can run wasm component workloads written in many programming languages. Learn more.

@thenewstack covered a talk I gave with Mikhail Krinkin at @rejektsio Europe 2025 on running Wasm workloads with hypervisor isolation, including a use case with Envoy filters. Worth a read: thenewstack.io/webassembly-hy…

Will be speaking at @rustconf this year about Hyperlight together w/ one of my co-workers, Ludvig Liljenberg! We'll be going over how Rust helped shape the design of the codebase, and how we ported it from C# to 100% Rust. Come say hi if you’re attending! #rustlang #hyperlight

Inference even in the browser! github.com/twitchax/kord I think the answer is, “yeah, but not for LLMs: just extremely specific use cases.”

This is why MCP tools must be sandboxed

👿 MCP is all fun, until you add this one malicious MCP server and forget about it. We have discovered a critical flaw in the widely-used Model Context Protocol (MCP) that enables a new form of LLM attack we term 'Tool Poisoning'. Leaks SSH key, API keys, etc. Details below 👇
