Which versions of notafollower1226 are malicious?

The following npm versions of notafollower1226 are flagged malicious: 1.0.0, 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.0.5. Treat any of these as compromised.

How do I remediate notafollower1226 if I installed it?

notafollower1226 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 notafollower1226 — how do I know if it already compromised me?

If notafollower1226 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 notafollower1226 part of a known attack campaign?

Yes — notafollower1226 is associated with the IN-MAL-2026-017763, IN-MAL-2026-017729, IN-MAL-2026-017764, IN-MAL-2026-017742, IN-MAL-2026-017778, IN-MAL-2026-017744 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 notafollower1226 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 notafollower1226 (6 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging notafollower1226 across your stack and pipelines.

What this malware does

The package.json postinstall script auto-executes on npm install. It queries the ECS container metadata endpoint (ECS_CONTAINER_METADATA_URI_V4/task) to collect the Task ARN, container image list, and log group/stream configuration, then enumerates process.env for keys matching /owner|team|user|created|author|maintainer|contact/i, and pipes the resulting report via curl -X POST --data-binary @- to the hardcoded anonymous ngrok tunnel https://mourner-slot-explicit.ngrok-free.dev. The destination is not associated with any declared publisher and ngrok-free.dev subdomains are ephemeral anonymous tunnels typical of supply-chain reconnaissance against CI/build infrastructure. The package ships no other functionality consistent with a legitimate declared purpose; its only install-time effect is the exfiltration beacon.

Detection & response playbook

Credential / info stealer

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for notafollower1226 (6 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging notafollower1226 across your stack and pipelines.
If you installed it — respond
notafollower1226 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 notafollower1226 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 notafollower1226 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.
