package.json declares `"preinstall": "./vendor/setup"`, which runs a 976,568-byte Linux ELF binary on every `npm install`. The package's stated purpose is a small React/Next.js Arweave routing helper (dist/esm/index.js) — there is no documented or structural reason for it to ship or execute a native binary. The binary is packed/obfuscated (mostly non-printable string output, no README or docs explaining its role) and is invoked solely from the install lifecycle hook, with no source, build script, or hash verification accompanying it. Extracted strings include LIBBPF_0.0, ~PTRACE, /proc references, USERPROFILE, https://, HTTP/1.1, GitHub API version `2022-11-28`, Ed25519, RSA_PKCS1_, and POST/DELETE verbs — fingerprints consistent with a credential-harvesting / GitHub-API-abusing payload with anti-debug instrumentation. The binary is not version-pinned to any publisher release, not hash-verified, and the package's advertised purpose is unrelated to any of the binary's apparent capabilities. This matches the opaque-native-binary-with-doc-mismatch and generic-binary-runner-dropper attack patterns: arbitrary attacker-controlled native code executes on every installer's machine without consent or inspectability.

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.
