Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Consumer projects can lose their React dependencies and become unable to run or build. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Destructive Action - **Selected version:** 0.22.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook performs an unconsented destructive mutation of the consumer project by deleting React dependencies. This concrete install-time behavior warrants blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-16T13:49:01.546Z - **Finished:** 2026-10-16T13:49:32.520Z - **Download time:** 755 ms - **Static scan time:** 469 ms - **AI review time:** 29750 ms - **Total time:** 30974 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:** The install hook deletes React packages from the consumer project. This can break the project and other packages that rely on those peer dependencies. - **Trigger:** The package's postinstall hook runs during installation. - **Impact:** Consumer projects can lose their React dependencies and become unable to run or build. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-16T13:49:32.520Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook recursively removes node\_modules/react and node\_modules/react-dom from the install working directory. - **Attack narrative:** During installation, the package runs a postinstall command that recursively deletes React and React DOM from the consumer's node\_modules. The manifest also declares both packages as peer dependencies, so the hook can remove dependencies needed by the consumer project. - **Rationale:** The postinstall hook performs an unconsented destructive mutation of the consumer project by deleting React dependencies. This concrete install-time behavior warrants blocking publication. - **Files touched:** node\_modules/react, node\_modules/react-dom ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json defines a postinstall script that recursively removes node\_modules/react and node\_modules/react-dom., The same manifest declares react and react-dom as peer dependencies. ## Affected versions and remediation This report applies to @1interface/chat-core@0.22.0. - Avoid installing @1interface/chat-core@0.22.0. 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.
