AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package contains an import-time, obfuscated detached child-process launcher in a validator module. This is concrete hidden execution, not a package-aligned generator feature. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-14T08:26:59.988Z - **Finished:** 2026-07-14T08:29:18.606Z - **Download time:** 521 ms - **Static scan time:** 346 ms - **AI review time:** 137751 ms - **Total time:** 138618 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing the package loads the validator and immediately launches an obfuscated detached Node child process. The hidden second stage has access to filesystem, OS, path, and HTTPS APIs; no exact endpoint is statically visible without decoding the concealed payload. - **Trigger:** Import \`lib/generator.js\` or otherwise load \`lib/templates/config/validator.js\`. - **Impact:** Unconsented hidden code execution with potential local collection and network activity. - **Evidence paths:** package.json, lib/generator.js, lib/templates/config/validator.js, lib/utils.js, lib/hooksRegistry.js - **Review source:** ai\_review - **Reviewed:** 2026-07-14T08:29:18.606Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time obfuscated detached child-process payload. - **Attack narrative:** \`lib/generator.js\` imports \`validateTemplateConfig\` from \`lib/templates/config/validator.js\`. That validator contains a large obfuscated appendage which immediately invokes \`main()\`, spawns a detached, hidden \`node -e\` process with an obfuscated command, and unreferences it. Its wrapper imports filesystem, OS, path, HTTPS, and child-process modules. This import-time concealed execution is unrelated to validation and is a concrete malicious execution chain. - **Rationale:** The package contains an import-time, obfuscated detached child-process launcher in a validator module. This is concrete hidden execution, not a package-aligned generator feature. - **Files touched:** lib/generator.js, lib/templates/config/validator.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`lib/templates/config/validator.js:69\` contains a 7.6KB obfuscated injected payload., Payload executes \`main()\` at module load, before validator exports are used., Payload imports \`child\_process\` and calls detached hidden \`spawn(...).unref()\`., Spawned process is \`node -e\` with an obfuscated second-stage command., Payload also imports \`fs\`, \`os\`, \`path\`, and \`https\`, inconsistent with template validation., \`lib/generator.js:14\` imports this validator, so importing the package triggers it. - **Evidence against:** \`package.json\` has no preinstall/install/postinstall lifecycle hook., The surrounding validator code is ordinary template configuration validation., Normal generator file writes and template installation are user-invoked features. ## Affected versions and remediation This report applies to @asyncapi/generator@3.3.1. - Avoid installing @asyncapi/generator@3.3.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
