OpenSSF/OSV advisory MAL-2026-4545 confirms this npm version as malicious. package.json declares "preinstall": "./scripts/postbuild", and scripts/postbuild is a 976,568-byte stripped Linux x86 ELF (sha256 36abd242…). The package advertises itself as a Node.js CosmWasm/AO contract scaffolding tool — a pure JavaScript use case with no documented native component. Nothing in README or index.js references this binary or any native build step, and no source for it is shipped... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to cwao-tools@0.3.1. - Avoid installing cwao-tools@0.3.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% package.json declares "preinstall": "./scripts/postbuild", and scripts/postbuild is a 976,568-byte stripped Linux x86 ELF (sha256 36abd242…). The package advertises itself as a Node.js CosmWasm/AO contract scaffolding tool — a pure JavaScript use case with no documented native component. Nothing in README or index.js references this binary or any native build step, and no source for it is shipped. Strings extracted from the binary include LIBBPF, PTRACE, NETLINK\_DIAG, RSA, Ed25519, HTTP/1.1, TLS, and USERPROFILE — kernel-introspection (eBPF/ptrace), cryptographic, and HTTP/TLS capability that has no relationship to scaffolding code generation. The script is named \`postbuild\` despite being wired to the \`preinstall\` lifecycle hook, a cover-story naming choice consistent with evading casual review. Running \`npm install cwao-tools\` immediately executes this opaque native binary with the installer's privileges, giving the publisher arbitrary code execution on the installer's machine on every install. \#\# Source: google-open-source-security (146faaf0d97c6a533a969bc3f3f117811f9317dc865ed4ab37f1679842ddeaae) This package was compromised as part of the IronWorm campaign. This campaign executes a malicious binary payload during installation via a preinstall hook. The payload is a Rust-built infostealer that targets developer environments, scanning for and harvesting credentials related to cloud providers, object storage, databases, source-control, package registries, and AI developer tools. It also targets cryptocurrency wallets, specifically injecting a malicious JavaScript hook into the Exodus desktop wallet to capture passwords and recovery phrases. Furthermore, the malware exhibits worm-like behavior by stealing GitHub and NPM credentials to push malicious updates to the victim's repositories and publish trojanized packages, and it uses an eBPF-based kernel rootkit to hide its processes and network connections on Linux systems. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** cwao-tools - **Ecosystem:** npm - **Version:** 0.3.1 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 0.3.1 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [ARTICLE]() - [ARTICLE]()
