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.

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 (version 1.0.1). 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.
