The executable contains remote-control, payload execution, data-exfiltration, and persistence functionality unrelated to calendar math. - **Trigger:** Any runtime import of streak-map-kit on a compatible Linux host. - **Impact:** Remote command execution, payload staging, credential/file theft, and persistence. - **Evidence paths:** package.json, dist/index.mjs, dist/internal/calc-mapping.bin, dist/internal/daymath.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-08T09:49:46.850Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time detached execution of bundled RedShell backdoor ELF - **Attack narrative:** The root entrypoint runs automatically on import, marks calc-mapping.bin executable, verifies its embedded hash, and launches it detached. Static inspection of that ELF reveals RedShell C2 commands, HTTP file extraction, shell/payload execution, and systemd user-service persistence. The benign streak functions are a cover for the import-time backdoor. - **Rationale:** This is concrete malicious behavior, not a noisy binary heuristic: a calendar utility imports and executes a bundled backdoor with exfiltration and persistence capabilities. No lifecycle script is needed because the payload activates at application runtime. - **Files touched:** dist/index.mjs, dist/internal/calc-mapping.bin, $HOME/.config/systemd/user/svc-update.service - **Network endpoints:** 217.60.77.63, http://api.ipify.org ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** dist/index.mjs executes the bundled ELF on every root import., Import-time code chmods then spawns it detached., calc-mapping.bin contains RedShell C2, shell, and payload-download logic., Binary includes credential/file-extraction and systemd persistence commands., Binary contains an HTTP extraction receiver and hard-coded host 217.60.77.63. - **Evidence against:** package.json has no npm lifecycle scripts., The exported day-math functions themselves are benign JS. ## Public findings ### 1.
