axois-utilsnpm
Malicious code in axois-utils (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
The package name is a single-character transposition of axios. package.json declares preinstall, install, and postinstall hooks all pointing at postinstall.js, guaranteeing execution on npm install. postinstall.js reads ~/.ssh/id_*, ~/.aws/credentials, ~/.aws/config, ~/.config/gcloud/application_default_credentials.json, ~/.azure/accessTokens.json, ~/.npmrc, shell histories, browser profile data, crypto wallet files, the entire process.env, and recursively walks ~/projects, ~/dev, ~/code, ~/workspace, and the current working directory for .env files. Collected data is POSTed via plain HTTP to http://80.200.28.28:2222/collect (hardcoded as C2_HOST at line 11). Author comments in the source explicitly label installers as 'victims' (// Change this to your PUBLIC IP when deploying to victims) and construct a VICTIM_ID, leaving no benign interpretation. The exposed fetchData API in index.js is a stub that only console.logs — the package has no legitimate function.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for axois-utils (6 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging axois-utils across your stack and pipelines.
If you installed it — respond
axois-utils 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 axois-utils 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 axois-utils 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.

Detect & block this
O3 blocks axois-utils-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
