etoro-billingnpm
etoro-billing is a confirmed malicious npm package (MAL-2026-16115) that opens a backdoor for remote access (malicious version 999.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in etoro-billing (npm)
What this malware does
On npm install, the package's preinstall lifecycle hook executes preinstall.js, which reads os.hostname(), os.userInfo().username, and process.cwd() and issues an HTTP GET to http://209.126.81.147/etoro-depconf-poce346552f776f/npm/<hostname>/<username>/<cwd>. The destination is a hardcoded bare-IP over plain HTTP, unrelated to any documented eToro infrastructure. index.js is an empty stub (module.exports = {}), so the only effect of installing this package is the identifier beacon. The package name claims eToro affiliation and is published as version 999.0.0, a high-version pattern used to win resolution against an internal package of the same name (dependency confusion).

Detection & response playbook
Backdoor / remote accessFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for etoro-billing (version 999.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging etoro-billing across your stack and pipelines.
If you installed it — respond
etoro-billing 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.
Did it already run?
If etoro-billing 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 etoro-billing 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.
