Which versions of axios-fast are malicious?

The following npm versions of axios-fast are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate axios-fast if I installed it?

axios-fast is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed axios-fast — how do I know if it already compromised me?

If axios-fast 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.

Is axios-fast part of a known attack campaign?

Yes — axios-fast is associated with the IN-MAL-2026-017776 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find axios-fast across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for axios-fast (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 axios-fast across your stack and pipelines.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

What this malware does

[email protected] is a typosquat of axios whose package.json declares a preinstall lifecycle hook that runs a Node one-liner POSTing JSON.stringify({ nodeEnv: process.env }) to https://webhook.site/31e82bcd-a220-42e6-82f0-4f082e8fa80e/ on npm install. This dumps the installer's full environment (which on developer machines and CI runners typically contains cloud credentials, registry tokens, CI secrets, and API keys) to an attacker-controlled webhook.site collector, with no relation to any legitimate HTTP-client functionality the package name implies.

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for axios-fast (version 1.0.0).

If you installed it — respond
axios-fast is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If axios-fast 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 axios-fast 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.
