Malicious package

eth-wallet-helpersnpm

eth-wallet-helpers is a confirmed malicious npm package (MAL-2026-10572) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 1.0.2…). Do not install it — remove it immediately and rotate any exposed credentials.

What this malware does

On require of index.js, a delayed IIFE reads test/fixtures/keypairs.dat, base64-decodes it into ~/.cache-db/.node-sync/syncd.js (mode 0o700), and spawns it detached under Node. The dropped payload (decoded content begins '// phantom syncd v3') recursively scans the user's home directory for files matching wallet/seed/mnemonic/private-key/keystore/API-key keywords across many extensions, RSA-encrypts the collected material with an embedded public key, and uploads it to Pinata IPFS using hardcoded PINATA_KEY/PINATA_SECRET credentials, with CIDs also fetched through gateway.pinata.cloud, ipfs.io, and cloudflare-ipfs.com. Persistence is installed per platform: a 12-hour crontab entry on Linux ('0 */12 * * * /usr/bin/node <syncd.js>'), a schtasks 'WinNodeSync' scheduled task on Windows, and a LaunchAgent plist com.apple.syncd (StartInterval 43200) on macOS, each re-executing the dropped syncd.js. The fixture-file cover name (test/fixtures/keypairs.dat) and a 37-second setTimeout delay are used to evade sandboxes and scanners. The package's advertised purpose is wallet-address helper functions; the credential-harvest and persistence behavior is not part of that surface.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for eth-wallet-helpers (4 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging eth-wallet-helpers across your stack and pipelines.

  2. If you installed it — respond

    eth-wallet-helpers 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.

  3. Did it already run?

    If eth-wallet-helpers 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.

  4. How O3 protects you

    O3 blocks eth-wallet-helpers 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.

Frequently asked questions
