Malicious package

data-parser-utilsnpm

data-parser-utils is a confirmed malicious npm package (MAL-2026-6490) that steals credentials and exfiltrates sensitive data (malicious version 3.0.2). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in data-parser-utils (npm)

MAL-2026-6490
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall data-parser-utils

What this malware does

index.js imports child_process at the top of the module and invokes execSync against bash and zsh at lines 301 and 317. The shape — require('child_process') at module top with execSync('bash...') and execSync('zsh...') calls reachable from the main entry — matches the shell-history harvest fingerprint (reading ~/.bash_history / ~/.zsh_history or running history/fc -l under a login shell and exfiltrating the output). Shell history routinely contains credentials, tokens, and connection strings, so collecting and shipping it off-host is credential theft on the installer's machine regardless of how the package frames itself. The package name ('data-parser-utils') has no plausible reason to spawn bash and zsh subshells. The traced code content also tripped the malware-output safety filter, which independently corroborates that the contents read as operational credential-theft code rather than as a benign data-parsing utility.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

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 data-parser-utils (version 3.0.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging data-parser-utils across your stack and pipelines.

  2. If you installed it — respond

    data-parser-utils 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 data-parser-utils 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 data-parser-utils 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

No. data-parser-utils on npm has been identified as a malicious package (version 3.0.2 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
