Which versions of bip39-generator are malicious?

The following npm versions of bip39-generator are flagged malicious: 3.1.2. Treat any of these as compromised.

How do I remediate bip39-generator if I installed it?

bip39-generator 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 bip39-generator — how do I know if it already compromised me?

If bip39-generator 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 bip39-generator part of a known attack campaign?

Yes — bip39-generator is associated with the IN-MAL-2026-015783 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 bip39-generator across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for bip39-generator (version 3.1.2).

Advisory published Aug 5, 2026Updated Aug 5, 2026

bip39-generator is a confirmed malicious npm package (MAL-2026-13257) that steals credentials and exfiltrates sensitive data (malicious version 3.1.2). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

npm uninstall bip39-generator

What this malware does

On module load, index.js JSON-serializes the full process.env together with hostname, username, homedir, platform, and cwd, base64-encodes the blob, and sends it as an HTTPS GET to api.telegram.org using a hardcoded bot token and chat_id 8969499041. A tmpdir marker file suppresses re-sends. The package presents itself as a 'drop-in replacement for bip39' and exports non-functional wallet/mnemonic stubs (generateMnemonic returns random hex, createWallet/signTransaction return placeholder values), consistent with a typosquat lure targeting crypto developers. Any process that requires this package leaks its environment variables (typically including API keys, cloud credentials, and CI secrets) and host identity to the attacker's Telegram channel.
