Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to akamaijs-sensor@3.0.0. The same advisory and Firewall decision cover these 2 recorded versions: 3.0.0, 2.0.0. - Avoid installing akamaijs-sensor@3.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The package presents itself as an Akamai sensor generator but ships two coupled malicious mechanisms. index.js contains a /\* \*/ comment filled with invisible Unicode variation-selector characters (U+FE00-FE0F and U+E0100-E01EF) that encode arbitrary JavaScript bytes. sync-metrics.js reads that comment, decodes the hidden bytes via an unpack() routine mapping the variation-selector ranges to nibbles, and executes the resulting source through new Function('require', batch)(require) — running attacker-authored code inside the consumer's Node process the first time the exported sensor() API is called. Separately, index.js fetches a hardcoded personal Google Calendar ICS feed at calendar.google.com/calendar/ical/hev4229%40gmail.com/public/basic.ics, extracts a URL from event DESCRIPTION fields (accepting plain, base64-decoded, or HTML href forms), appends /generate, GETs that endpoint and returns its JSON to sensor()'s caller. The calendar functions as a dead-drop the operator rotates by editing calendar events, defeating static URL indicators and letting the operator swap the live endpoint at will. The combination — invisible-Unicode-encoded code executed via new Function() plus an attacker-rotatable C2 channel whose responses flow back through the package's advertised API — is remote code execution against the installer with no legitimate purpose in a sensor generator. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** akamaijs-sensor - **Ecosystem:** npm - **Version:** 3.0.0 - **Version published:** 2026-07-30T09:31:23.699Z - **Package first seen:** 2026-08-05T13:30:18.056Z - **Package last seen:** 2026-08-15T18:20:05.667Z - **Known versions:** 2 - **Latest version:** 3.0.0 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]()
