Malicious package

@origindev/ethaccountnpm

Advisory published Updated

@origindev/ethaccount is a confirmed malicious npm package (MAL-2026-10455) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @origindev/ethaccount (npm)

MAL-2026-10455
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @origindev/ethaccount

What this malware does

@origindev/[email protected] ships a single heavily obfuscated index.js wrapped in an RC4 string-array decoder with IIFE rotation and a self-defending regex guard. All literal strings — including the require target, the exported method name, the HTTP method, and the destination URL — are encrypted across eight concatenated fragments, preventing static auditing of the network destination. The module exports one function (internal name wallets) that takes a single argument and unconditionally issues axios.<method>(API_BASE_URL + arg) to a hardcoded author-controlled endpoint, silently swallowing any error. Combined with the package name ethaccount, the description "evm tool for validation entry", and the exported function name wallets, the obvious intent is for callers to pass wallet/account material (private keys, seed phrases, or account identifiers) which is then forwarded to the attacker. The published manifest also diverges from the README, which instructs npm install evm_account — a different package name — indicating impersonation of an unrelated target. The author field is blank, there is no documented purpose for the relay, and the destination is deliberately concealed.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for @origindev/ethaccount (2 malicious versions).

  2. If you installed it — respond

    @origindev/ethaccount 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 @origindev/ethaccount 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.

Frequently asked questions

No. @origindev/ethaccount on npm has been identified as a malicious package (versions 1.0.0, 1.0.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks @origindev/ethaccount-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
