weavedb-consolenpm
Malicious code in weavedb-console (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
package.json declares "preinstall": "./src/compiler/native", which auto-executes a 976 KB stripped Linux ELF binary on every npm install. The binary is undocumented — no source is shipped, no README mention, and no JavaScript code in the package references it. Extracted strings show system-introspection capabilities (libbpf/eBPF, ptrace, netlink-diag), cryptographic primitives (RSA, Ed25519, MLKEM), an HTTP/1.1 client, GitHub REST API references (api.github.com, version header 2022-11-28), XMLHttpRequest, and USERPROFILE — a system-introspection plus networking surface entirely inconsistent with the package's stated purpose (a Next.js admin console for WeaveDB, which requires no native compilation step). The binary is stripped and cannot be inspected before npm runs it. Installer harm: arbitrary attacker-controlled native code runs with the installer's privileges on npm install, with surface area (eBPF/ptrace) suggesting credential and process-memory access, and outbound HTTP/GitHub-API capability for exfiltration or further payload retrieval.
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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for weavedb-console (version 0.2.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging weavedb-console across your stack and pipelines.
If you installed it — respond
weavedb-console is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If weavedb-console was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks weavedb-console before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Detect & block this
O3 blocks weavedb-console-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
