package.json declares "preinstall": "./scripts/postbuild", where scripts/postbuild is a 976,568-byte Linux x86-64 ELF binary shipped in the tarball with no corresponding source, no native build configuration (no binding.gyp, no.c/.cc/.rs files, no node-gyp/cmake-js/prebuild-install tooling), and no mention in README. The package self-describes as a pure-JS Arweave/AO unit runner whose declared dependencies (arweave, express, cors, ramda, weavedb) are all pure JavaScript — there is no legitimate cover story for a platform-specific native binary. Strings inside the ELF include LIBBPF_0.0, PTRACE, NETLINK, HTTP/1.1, https://, Ed25519/RSA/MLKEM crypto primitives, and USERPROFILE, indicating network-capable, BPF/ptrace-capable native code. Every npm install cwao-units executes this opaque binary as the installer's user before the package is even loaded. The filename postbuild is suggestively chosen to mimic a benign build artifact, and the binary is invoked as a preinstall (not postinstall) hook so it fires before any inspection. This matches the canonical opaque-binary dropper pattern: doc-mismatch + thin lifecycle-script wrapper + undocumented native code with networking/tracing primitives.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

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.
