Malicious package

dojo-rn-interviewnpm

dojo-rn-interview is a confirmed malicious npm package (MAL-2026-13549) that opens a backdoor for remote access (malicious versions 1.0.1, 1.1.1). 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 dojo-rn-interview

What this malware does

[email protected] declares a preinstall script that runs index.js on npm install. The script collects host identifiers via os.hostname(), os.userInfo(), os.homedir(), __dirname, and DNS server list, and reads the installer's /etc/passwd and /etc/hosts files, then POSTs the collected data over HTTPS to the hardcoded Burp Collaborator subdomain kqepxa9s4krgw7e7b6f7kufiy943stgi.oastify.com. The package name and behavior are consistent with a dependency-confusion reconnaissance beacon targeting internal build systems.

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

Backdoor / remote access
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for dojo-rn-interview (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging dojo-rn-interview across your stack and pipelines.

  2. If you installed it — respond

    dojo-rn-interview establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

  3. Did it already run?

    If dojo-rn-interview 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 dojo-rn-interview 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.
