Which versions of wdb-cli are malicious?

The following npm versions of wdb-cli are flagged malicious: 0.1.1. Treat any of these as compromised.

How do I remediate wdb-cli if I installed it?

wdb-cli 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.

I already installed wdb-cli — how do I know if it already compromised me?

If wdb-cli was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is wdb-cli part of a known attack campaign?

Yes — wdb-cli is associated with the IN-MAL-2026-004816 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find wdb-cli across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for wdb-cli (version 0.1.1).

Malicious package

Advisory published May 26, 2026Updated Jun 4, 2026

wdb-cli is a confirmed malicious npm package (MAL-2026-4713) that steals credentials and exfiltrates sensitive data (malicious version 0.1.1). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall wdb-cli

What this malware does

package.json declares "preinstall": "./vendor/setup", which on every npm install invokes a 976568-byte Linux x86 ELF binary shipped inside the package tarball (sha256 36abd242…6d36). The binary has no accompanying source, no binding.gyp, no build step, and is not documented anywhere in the package. Strings inside the ELF reveal capabilities (LIBBPF_0.0, PTRACE, NETLINK, HTTP/1.1, https://, RSA crypto) that have no plausible relationship to a database CLI's installation. The installer cannot inspect the bytes before they execute, the binary is not hash-verified, and it is not pulled from a publisher-matching, version-pinned release. Any developer or CI environment running npm install wdb-cli therefore executes opaque, attacker-controllable native code with the invoking user's privileges, with eBPF/ptrace primitives that enable kernel-level observation and process tampering, and with built-in HTTPS capability for outbound exfiltration or C2. A separate file (workspace/.wallet.json) ships a full RSA private key, but that appears to be author self-harm (the author's own dev wallet copied into user-created project scaffolds via an explicit CLI subcommand) and is not the basis for this verdict.

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.
