The native payload cannot be source-audited here, so its behavior remains unresolved. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 82.0% - **Started:** 2026-08-14T06:17:46.596Z - **Finished:** 2026-08-14T06:20:04.708Z - **Download time:** 762 ms - **Static scan time:** 1275 ms - **AI review time:** 136074 ms - **Total time:** 138112 ms ## Security analysis ### Published attack-surface review - **Summary:** Conditional E2EE operation loads a stripped package-native library with authenticated Facebook cookies. The native payload cannot be source-audited here, so its behavior remains unresolved. - **Trigger:** Caller enables E2EE and starts a logged-in client. - **Impact:** Native code can access supplied session cookies during E2EE connection. - **Evidence paths:** package.json, index.js, e2ee.js, e2eebot.js, lib/index.mjs, src/getAccess.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T06:20:04.708Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** conditional native Messenger client loading - **Rationale:** No concrete malicious chain is established in inspectable source, but opaque executable libraries receive authentication cookies at runtime. This warrants a warning rather than a publish block. - **Files touched:** e2ee.js, lib/index.mjs, build/messagix.so, build/messagix.dll - **Network endpoints:** https://www.facebook.com/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for:** Ships stripped native ELF/PE payloads loaded through koffi., E2EE runtime dynamically loads local native code and passes Facebook session cookies to it. - **Evidence against:** package.json has no preinstall/install/postinstall hook., Main entrypoint exports a login function; no import-time network or native execution found., Visible JS endpoints are Facebook-aligned; no webhook or third-party credential-exfiltration endpoint found., No child-process execution or destructive filesystem operation found in inspected JS. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** e2eebot.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern. Public source snippet (untrusted): ```javascript L8: async function importESM(specifier) { L9: const dynamicImport = new Function("specifier", "return import(specifier)"); L10: return dynamicImport(specifier); ``` ### 3. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** e2eebot.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L3: L4: const fs = require("fs"); L5: ``` ### 4. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. High: Copied Package Dependency Bridge - **Category:** Source - **Confidence:** 83.0% - **Path:** index.js - **Public source:** [View source]() Package metadata claims a different repository identity while copied source loads a runtime dependency bridge. Public source snippet (untrusted): ```javascript package = fca-sahu; repositoryIdentity = sahu-fca; dependency = axios L379: try { L380: const axios = require('axios'); L381: const FormData = require('form-data'); ``` ### 7. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 8. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 9. Medium: Ships Native Binary - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** build/messagix.so - **Public source:** [View source]() Package ships native binary artifacts. Public source snippet (untrusted): ```text path = build/messagix.so kind = native_binary sizeBytes = 17504872 magicHex = [redacted] ``` ### 10. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 11. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** src/getAccess.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 = fca-sahu@0.0.3 matchedPath = src/getAccess.js matchedIdentity = npm:ZmNhLXNhaHU:0.0.3 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 12. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** index.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = fca-sahu@0.0.2 matchedIdentity = npm:ZmNhLXNhaHU:0.0.2 similarity = 0.948 summary = stored previous version shares package body but lacks this dangerous source file ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 17 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 17 ### Published dependency entries - axios ^1.8.4 (Dependency) - bluebird ^3.7.2 (Dependency) - chalk ^4.1.2 (Dependency) - cheerio ^1.0.0-rc.10 (Dependency) - duplexify ^4.1.3 (Dependency) - form-data ^4.0.4 (Dependency) - gradient-string ^2.0.2 (Dependency) - https-proxy-agent ^7.0.6 (Dependency) - koffi ^3.0.2 (Dependency) - mime ^3.0.0 (Dependency) - mqtt ^5.10.1 (Dependency) - npmlog ^1.2.0 (Dependency) - request ^2.88.2 (Dependency) - totp-generator ^1.0.0 (Dependency) - undici ^8.4.0 (Dependency) - ws ^8.18.1 (Dependency) - yumi-json-bigint ^1.0.0 (Dependency) ## Package metadata - **Package:** fca-sahu - **Ecosystem:** npm - **Version:** 0.0.5 - **License:** MIT - **Version published:** 2026-08-14T06:15:47.564Z - **Package first seen:** 2026-08-14T05:10:08.764Z - **Package last seen:** 2026-08-14T06:20:04.708Z - **Known versions:** 3 - **Latest version:** 0.0.5 - **Appeal under review:** No - **Description:** Unofficial Facebook Chat API for Node.js with enhancements by SHAHADAT SAHU - **Author:** SHAHADAT SAHU - **Maintainers:** sahu-uhas - **Keywords:** facebook, facebook-api, chat, chat-api, messenger, messenger-api, bot, chatbot, fca, facebook-chat-api, messenger-bot, nodejs - **Artifact files:** 100 - **Artifact unpacked size:** 33,881,138 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
