The payload is appended to an otherwise readable postinstall script and its behavior cannot be audited from the visible source. - **Trigger:** npm installation of the package as a dependency outside CI. - **Impact:** Arbitrary hidden code can run with the installing user's permissions. - **Evidence paths:** package.json, scripts/postinstall.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-27T16:11:26.539Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated install-hook payload reconstruction and execution. - **Attack narrative:** The package declares a postinstall hook. Its script first appears to create a TestRelic configuration file, then appends dense obfuscated code that reconstructs data into callable code and invokes it. This runs during dependency installation, before the user explicitly runs the package. Because the executed payload is deliberately concealed, its file, process, and network actions are not reviewable or consented to. - **Rationale:** This is an automatic install-time hidden-code execution chain, not normal reporter functionality. Block publication to prevent arbitrary concealed code from running during installation. - **Files touched:** scripts/postinstall.cjs, .testrelic/testrelic-config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs scripts/postinstall.cjs automatically after installation., The postinstall script has a large, concealed decoder appended after its visible configuration code., The concealed code reconstructs callable code and immediately invokes the resulting payload. - **Evidence against:** The readable portion of the postinstall script creates a same-vendor configuration file and skips CI., The reporter's cloud upload features match the stated analytics purpose, but do not explain the hidden install-time payload. ## Public findings ### 1.
