This is unconsented postinstall telemetry. - **Trigger:** npm install / dependency installation - **Impact:** External recipient receives local hostname, username, working directory, and environment-state metadata. - **Evidence paths:** package.json, canary.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T12:38:52.923Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall host-fingerprint exfiltration over HTTP - **Attack narrative:** On installation, npm invokes canary.js through postinstall. The script gathers local host identity and execution-context metadata, then sends it by HTTP POST to a fixed external OAST endpoint. The package description identifies this as a dependency-confusion PoC, but it still performs the callback without installer consent. - **Rationale:** Direct source inspection confirms an install-triggered external exfiltration callback. The benign placeholder runtime export does not mitigate the postinstall behavior. - **Files touched:** package.json, canary.js, index.js - **Network endpoints:** 2pslbvbc3adfni1pbe9xy2b1asgj4cs1.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node canary.js\` on postinstall., canary.js collects hostname, username, cwd, CI and NODE\_ENV., canary.js POSTs collected data to an external OAST host during install., Manifest describes a dependency-confusion validation PoC. - **Evidence against:** index.js only exports a placeholder object., No shell execution, file writes, or payload loading found. ## Public findings ### 1.
