AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The main entry point appends an obfuscated base64 payload that executes at import time and retrieves and runs remote code using a host derived from Ethereum transaction data. This is concealed, automatic remote-code execution unrelated to the package's stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-11-03T23:38:15.154Z - **Finished:** 2026-11-03T23:40:05.672Z - **Download time:** 771 ms - **Static scan time:** 99 ms - **AI review time:** 109647 ms - **Total time:** 110518 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:** Malicious obfuscated remote-code loader runs when the package is imported. - **Trigger:** Importing the package through its declared main entry point. - **Impact:** Allows an attacker to run remotely supplied code in the importing application's Node process context. - **Evidence paths:** lib/index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-11-03T23:40:05.672Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entry point evaluates a base64-encoded payload. It queries embedded Ethereum RPC and transaction-indexing endpoints, derives an IP address from on-chain transaction data, fetches remote content, evaluates it, and launches a detached interactive Node process. - **Attack narrative:** Importing the package executes an obfuscated payload appended to its main bundle. The payload discovers a host through Ethereum transaction data, retrieves remote code, evaluates it, and launches a detached Node process. This behavior is unrelated to browser activity tracking and runs without a user command. - **Rationale:** The main entry point appends an obfuscated base64 payload that executes at import time and retrieves and runs remote code using a host derived from Ethereum transaction data. This is concealed, automatic remote-code execution unrelated to the package's stated purpose. - **Network endpoints:** https://1rpc.io/eth, https://ethereum-rpc.publicnode.com, https://eth.drpc.org, https://api.etherscan.io/api, http://\ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest sets lib/index.js as the package main entry point., The entry point contains an eval(atob(...)) payload appended to the bundled library., Static decoding shows the payload runs automatically, queries Ethereum RPC and transaction-indexing services, derives a remote host from transaction data, then fetches and executes code and starts a detached Node process. - **Evidence against:** The declared package purpose and ordinary library code concern browser activity tracking and GraphQL tracing., The manifest has no install lifecycle hooks; its scripts are for building, testing, and prepublishing. ## Affected versions and remediation This report applies to @adminide-stack/user-activity-browser@1.1.3-alpha.114. - Avoid installing @adminide-stack/user-activity-browser@1.1.3-alpha.114. 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.
