It reads host identity and network details plus /etc/passwd and /etc/hosts, then sends them in an HTTPS POST to a Burp Collaborator-style oastify endpoint. - **Rationale:** Source directly confirms unconsented install-time collection and exfiltration of local system data. This is concrete malicious behavior, not merely a suspicious primitive. - **Files touched:** package.json, index.js, /etc/passwd, /etc/hosts - **Network endpoints:** 67bqctsh977zz60hiszvr1pbc2iu6ku9.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node index.js\` in preinstall., index.js collects hostname, username, home directory, and DNS servers., index.js reads /etc/passwd and /etc/hosts when present., index.js POSTs collected data to an oastify host. ## 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 index.js ``` ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 4. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. High: Host Fingerprint Exfiltration - **Category:** Source - **Confidence:** 86.0% - **Path:** index.js - **Public source:** [View source]() Source collects local host identity data and sends it to an external endpoint. Public source snippet (untrusted): ```javascript L1: const os = require("os"); L2: const dns = require("dns"); L3: const fs = require("fs"); L4: const https = require("https"); L5: const packageJSON = require("./package.json"); L6: const packageName = packageJSON.name; ... L10: p: packageName, // Package name L11: c: __dirname, // Directory where the package is installed L12: hd: os.homedir(), // Home directory on the remote server L13: hn: os.hostname(), // Hostname of the remote server L14: un: os.userInfo().username, // Username on the remote server ... L17: pjson: packageJSON, // Full package.json data ``` ### 6. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** index.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = normalized_sha256 matchedPackage = knowledge-grader@1.0.1 matchedPath = index.js matchedIdentity = npm:a25vd2xlZGdlLWdyYWRlcg:1.0.1 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 7. High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** index.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 = 5442fb9217b0dd0a signatureType = suspicious_hashes sourceLabel = final_verdict:malicious matchedPackage = knowledge-grader@1.0.1 matchedPath = index.js matchedIdentity = npm:a25vd2xlZGdlLWdyYWRlcg:1.0.1 similarity = 1.000 shingleOverlap = 1 summary = package final verdict is malicious ``` ## 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:** forge-extended - **Ecosystem:** npm - **Version:** 1.0.1 - **License:** ISC - **Version published:** 2026-07-22T18:26:14.298Z - **Package first seen:** 2026-07-22T18:29:12.987Z - **Package last seen:** 2026-07-22T18:29:12.987Z - **Known versions:** 1 - **Latest version:** 1.0.1 - **Appeal under review:** No - **Artifact files:** 2 - **Artifact unpacked size:** 2,264 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
