webassembly security

About this tag
WebAssembly security on WindowsForum.com covers the use of WebAssembly (WASM) in both offensive and defensive security contexts. Discussions include hardening Remote Desktop Protocol (RDP) by enforcing Network Level Authentication (NLA) and using WASM tools like wazero and IronRDP to detect sticky keys backdoors. Microsoft's Wassette framework leverages Rust and WebAssembly to create secure, cross-platform AI agents that fetch and execute WASM components from OCI registries. Additionally, vulnerabilities in the V8 engine, such as CVE-2025-5959, a type confusion bug affecting JavaScript and WebAssembly, are analyzed for their impact on Chromium-based browsers including Microsoft Edge. These threads highlight WASM's growing role in security tooling, vulnerability research, and enterprise IT defense.
