AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package's automatic postinstall script downloads and executes a concealed miner, with privileged and unprivileged execution paths. This is concrete malicious install-time behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-10-22T03:36:50.316Z - **Finished:** 2026-10-22T03:37:11.076Z - **Download time:** 1026 ms - **Static scan time:** 245 ms - **AI review time:** 19488 ms - **Total time:** 20760 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 automatic postinstall hook downloads and runs a concealed cryptocurrency miner. It attempts a persistent privileged install when possible and otherwise runs an extracted miner under a stealth name. - **Trigger:** Installing the package with npm, which invokes its postinstall script. - **Impact:** Unauthorized cryptocurrency mining consumes the installing machine's resources; privileged execution can permit broader persistence and system changes. - **Evidence paths:** package.json, scripts/miner.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-22T03:37:11.076Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The shell script fetches and decompresses a remote carrier, executes it with root or passwordless sudo, or extracts and launches an XMRig binary and configures its mining pool. - **Attack narrative:** Installing this package automatically runs a shell script that downloads and decompresses a remote carrier. The script runs the carrier as root or through passwordless sudo when available; otherwise it extracts and launches an XMRig binary, configures a mining pool, and places the miner at a stealth-named path. This is an active install-time mining and persistence chain. - **Rationale:** The package's automatic postinstall script downloads and executes a concealed miner, with privileged and unprivileged execution paths. 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:** 100.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs scripts/miner.sh automatically during postinstall., The script downloads and decompresses a remote carrier without a consent check., The script launches the carrier with root or passwordless sudo, or extracts and runs an XMRig binary as an unprivileged user., The unprivileged path configures mining against networkservicesupp.flashhub.net:8443 and copies the miner to a stealth-named path. ## Affected versions and remediation This report applies to @sudobility/wildduck\_client@2.3.102. - Avoid installing @sudobility/wildduck\_client@2.3.102. 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.
