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.
- CWE-506 - The product contains code that appears to be malicious in nature.
