Which versions of cdk-insights are malicious?

The following npm versions of cdk-insights are flagged malicious: 1.41.2, 1.42.3, 1.58.1, 1.59.1, 1.59.2, 1.59.3, 1.60.0, 1.60.1, 1.61.0. Treat any of these as compromised.

How do I remediate cdk-insights if I installed it?

cdk-insights 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 cdk-insights — how do I know if it already compromised me?

If cdk-insights 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 do I find cdk-insights 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 cdk-insights (9 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging cdk-insights across your stack and pipelines.

Malicious package

cdk-insightsnpm

cdk-insights is a confirmed malicious npm package (MAL-2026-4508) that steals credentials and exfiltrates sensitive data (malicious versions 1.41.2, 1.42.3, 1.58.1…). Do not install it — remove it immediately and rotate any exposed credentials.

MAL-2026-4508

Immediate action

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

npm uninstall cdk-insights

What this malware does

The package contains code in dist/entry.js and dist/index.js that invokes npm publish programmatically combined with writeFileSync operations — the canonical wormable auto-publication pattern (enumerate maintainer's other packages, rewrite their package.json, republish under the installer's npm credentials). Additionally, dist/aspects/CdkInsightsAspect.js, dist/entry.js, and dist/index.js contain multiple HTTP POST sinks consistent with hardcoded C2 / data-exfiltration endpoints, and CdkInsightsAspect.js contains ping-based network reconnaissance. The combination of wormable self-propagation infrastructure plus exfiltration POST endpoints in install/import-reachable code is unambiguous supply-chain attack shape: any developer or CI system installing this package risks (a) having installer-side data POSTed to attacker-controlled endpoints and (b) having their npm credentials abused to republish malicious versions of their other packages.

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 cdk-insights (9 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging cdk-insights across your stack and pipelines.
If you installed it — respond
cdk-insights 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 cdk-insights 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 cdk-insights 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.
