gaarf-nodenpm
gaarf-node is a confirmed malicious npm package (MAL-2026-14238) that opens a backdoor for remote access (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in gaarf-node (npm)
What this malware does
The package's postinstall script runs automatically on npm install and collects host identifiers (os.hostname(), platform, arch, node version, package name, npm lifecycle event) and POSTs them as JSON to the hardcoded remote host ze0buq23.instances.poc.jchunt.top at path /gaarf-node. The package name impersonates Google's ads-api-report-fetcher (gaarf) project referenced in source.txt, while package.json self-labels as a Security research canary. The destination domain is unrelated to the impersonated Google project, and the outbound beacon fires with no user consent as a lifecycle side effect of installation.

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 gaarf-node (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging gaarf-node across your stack and pipelines.
If you installed it — respond
gaarf-node 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 gaarf-node 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 gaarf-node 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.
