The decoded payload collects local identity, directory, hostname, and /etc/passwd data and POSTs it remotely. - **Trigger:** Installing harmony-app-toolkit@21.0.0 - **Impact:** Leaks installation-host identity and local account data to an attacker-controlled collection endpoint. - **Evidence paths:** package.json, preinstall.js, preinstall.json - **Review source:** ai\_review - **Reviewed:** 2026-08-15T13:59:25.040Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** obfuscated install-time shell-based credential and host-data exfiltration - **Attack narrative:** During npm installation, the preinstall hook runs preinstall.js. That script decodes the hex command stored in preinstall.json and executes it. Static decoding shows a curl POST to eousft8gflamm91.m.pipedream.net containing whoami, pwd, hostname, and /etc/passwd contents. - **Rationale:** This is concrete, obfuscated, install-time data exfiltration with no user action beyond installation. It meets the blocking threshold. - **Files touched:** package.json, preinstall.js, preinstall.json, /etc/passwd - **Network endpoints:** https://eousft8gflamm91.m.pipedream.net ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Install lifecycle runs preinstall.js., preinstall.js hex-decodes a command and executes it via child\_process.exec., Decoded preinstall.json payload uses curl to exfiltrate user, path, host, and /etc/passwd data to eousft8gflamm91.m.pipedream.net. - **Evidence against:** No legitimate package implementation files are present; the package consists only of the install payload and manifest. ## 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 preinstall.js ``` ### 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.preinstall = node preinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** preinstall.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 = f243d5785c040017 signatureType = suspicious_hashes sourceLabel = final_verdict:malicious matchedPackage = require-i18next@20.0.0 matchedPath = preinstall.js matchedIdentity = npm:cmVxdWlyZS1pMThuZXh0:20.0.0 similarity = 1.000 shingleOverlap = 1 summary = package final verdict is malicious ``` ### 6. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() Install lifecycle runs preinstall.js. Public source snippet (untrusted): ```json "main": "index.js", "scripts": { "preinstall": "node preinstall.js" } ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** preinstall.json - **Public source:** [View source]() Decoded preinstall.json payload uses curl to exfiltrate user, path, host, and /etc/passwd data to eousft8gflamm91.m.pipedream.net. Public source snippet (untrusted): ```json "command": "[redacted]" ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** preinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** harmony-app-toolkit - **Ecosystem:** npm - **Version:** 21.0.0 - **License:** MIT - **Version published:** 2026-08-15T13:58:19.348Z - **Package first seen:** 2026-08-15T13:59:25.040Z - **Package last seen:** 2026-08-15T14:50:05.322Z - **Known versions:** 2 - **Latest version:** 22.0.0 - **Appeal under review:** No - **Description:** description - **Author:** kp-admin - **Artifact files:** 3 - **Artifact unpacked size:** 1,176 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]()
