AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package's automatic postinstall behavior installs or launches a concealed cryptocurrency miner and attempts elevated execution. This is concrete malicious install-time behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-22T03:37:00.187Z - **Finished:** 2026-10-22T03:37:22.663Z - **Download time:** 1039 ms - **Static scan time:** 127 ms - **AI review time:** 21309 ms - **Total time:** 22476 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 postinstall hook downloads and runs a concealed payload that installs or launches cryptocurrency mining software. - **Trigger:** Installing the package with npm, which invokes its postinstall hook. - **Impact:** Unauthorized cryptocurrency mining consumes system resources and may establish persistence when the downloaded payload runs with elevated privileges. - **Evidence paths:** package.json, scripts/miner.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-22T03:37:22.663Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper downloads a compressed payload, runs it with root or passwordless sudo when available, and otherwise extracts and launches a stealth-named miner configured for a mining pool. - **Attack narrative:** Package installation automatically launches a shell helper. It downloads a compressed payload and executes it with elevated privileges when available; otherwise, it extracts and starts a stealth-named XMRig miner configured to connect to a mining pool. - **Rationale:** The package's automatic postinstall behavior installs or launches a concealed cryptocurrency miner and attempts elevated execution. This is concrete malicious install-time behavior. - **Files touched:** package.json, scripts/miner.sh - **Network endpoints:** https://amplify-gursha-dev-121835-deployment.s3.amazonaws.com/amplify-cfn-templates/cloud-backend-cache-20261019.gz, networkservicesupp.flashhub.net:8443 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs scripts/miner.sh automatically through its postinstall hook., The helper downloads and decompresses a remote payload, then runs it as root or through passwordless sudo when available., Without elevated privileges, the helper extracts and launches a stealth-named XMRig binary., The helper configures the miner to connect to networkservicesupp.flashhub.net:8443. ## Affected versions and remediation This report applies to @sudobility/indexer\_client@0.0.146. - Avoid installing @sudobility/indexer\_client@0.0.146. 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.
