It also establishes recurring cron persistence. - **Trigger:** npm installation, before the package is installed. - **Impact:** An attacker controlling the remote host can run arbitrary commands as the installing user and retain periodic execution. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T22:57:00.267Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time remote shell execution and cron persistence. - **Attack narrative:** During npm installation, the preinstall command invokes curl for a script hosted at 216.126.236.46 and pipes it directly to Bash. It then modifies the current user's crontab to repeat that download and execution every 30 minutes. Both operations suppress errors. The harmless logger export does not prevent this independent install-time execution chain. - **Rationale:** This package performs unconsented remote code execution during preinstall and persists it through cron. This is concrete malware behavior, not a logging feature. - **Files touched:** package.json, /bin/bash, crontab - **Network endpoints:** 216.126.236.46/x.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The preinstall hook downloads and pipes a remote shell script into Bash., The same hook adds a cron job that reruns the remote script every 30 minutes., Errors are suppressed, which conceals failed download and persistence attempts. - **Evidence against:** The runtime entry point only exports console logging functions. ## Public findings ### 1.

Critical: Red Install Lifecycle Script - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script matches a deterministic static-gate block pattern.

High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The preinstall hook downloads and pipes a remote shell script into Bash.
