Description

Malicious code in test-weavedb-sdk (npm)

Source: amazon-inspector

Package name impersonates the legitimate weavedb-sdk; lib/index.js is a near-verbatim copy of that SDK's Arweave/Warp/EthCrypto class so the package functions as a drop-in substitute. package.json declares "preinstall": "./dist/runtime.node", directly executing a 976KB opaque ELF on every npm install. The.node extension is deceptive — legitimate Node native addons are loaded via require()/dlopen, not spawned as standalone executables. Strings recovered from the binary include HTTP/1.1, POST, DELETE, https://, USERPROFILE, LIBBPF_0.0 (eBPF), PTRACE, Ed25519, and RSA_PKCS1_ — capabilities (HTTP egress, kernel-level eBPF, anti-debug ptrace, home-directory enumeration, cryptographic operations) consistent with an info-stealer / C2 implant and unrelated to the package's advertised purpose. The binary ships without source, build system, or any documentation, and runs unconditionally with the installer's privileges at install time.

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.
