OpenSSF/OSV malware advisory MAL-2026-4544 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-4544 confirms this npm version as malicious. package.json declares "preinstall": "./vendor/setup", which directly executes a 976,568-byte packed Linux x86 ELF binary shipped in the tarball. The README advertises the package as a pure-JS CosmWasm/Arweave AO SDK and never mentions a native binary. The binary is opaque (mostly non-printable, UPX-style packing) with no shipped source, no binding.gyp, no node-gyp/prebuild-install manifest, no version pin and no...

## Affected versions and remediation

This report applies to cwao@0.5.6.

- Avoid installing cwao@0.5.6. 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": "./vendor/setup", which directly executes a 976,568-byte packed Linux x86 ELF binary shipped in the tarball. The README advertises the package as a pure-JS CosmWasm/Arweave AO SDK and never mentions a native binary. The binary is opaque (mostly non-printable, UPX-style packing) with no shipped source, no binding.gyp, no node-gyp/prebuild-install manifest, no version pin and no hash verification. Embedded string fragments include LIBBPF, PTRACE, /proc, HTTP/1.1, https://, RSA, and USERPROFILE — capabilities (kernel BPF, process tracing, outbound HTTPS, credential paths) entirely unrelated to a JavaScript SDK. Every installer running \`npm install cwao\` on Linux executes this attacker-controlled native code with the user's privileges before any JavaScript loads. This matches the generic-binary-runner-dropper pattern: undocumented binary, purpose mismatch with the advertised package function, opaque payload, no integrity check, direct lifecycle invocation.

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.
