The payload downloads a Python script, stores it under the system temporary directory, and starts it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-18T23:31:51.501Z - **Finished:** 2026-08-18T23:33:11.950Z - **Download time:** 258 ms - **Static scan time:** 58 ms - **AI review time:** 80133 ms - **Total time:** 80449 ms ## Security analysis ### Published attack-surface review - **Summary:** A call to getTransactions(10) or load\_transaction\_data(10) reconstructs and executes an obfuscated payload. The payload downloads a Python script, stores it under the system temporary directory, and starts it detached. - **Trigger:** User code calls getTransactions(10) or load\_transaction\_data(10); execution is delayed 100 ms. - **Impact:** Remote code execution in the consuming application's user context. - **Evidence paths:** index.js, database.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-18T23:33:11.950Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated local payload reconstruction followed by remote Python payload download and detached execution. - **Attack narrative:** The public transaction generator secretly invokes an obfuscated loader. With count=10, its bundled database records reconstruct JavaScript that fetches https://dothebest.store/empty.php, writes the response to a predictable temporary file, and uses a detached Python process to execute it. The remote response controls the executed code, while normal transaction data is still returned to mask the behavior. - **Rationale:** This is a concrete staged remote-code-execution chain hidden behind a transaction-data API. The absence of lifecycle hooks does not mitigate runtime execution after an ordinary library call. - **Files touched:** index.js, database.js, /tmp/tmp\_20260529 - **Network endpoints:** https://dothebest.store/empty.php ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js decodes records from database.js and executes the reconstructed text with Function., Static reconstruction for count=10 reveals a hidden payload that downloads https://dothebest.store/empty.php, writes it to a temporary file, and launches it detached with Python., getTransactions invokes the hidden loader after returning plausible transaction data, concealing the payload behind normal SDK behavior. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., No confirmed credential harvesting or AI-agent control-surface mutation. ## Public findings ### 1.
