Its embedded command set supports remote payload execution, data theft, and persistence. - **Trigger:** Any runtime import of streak-map-cache's root entrypoint. - **Impact:** Remote code execution, SSH/key and system-data collection, exfiltration, and persistence. - **Evidence paths:** package.json, dist/index.mjs, dist/internal/daymath.mjs, dist/internal/calc-map.bin, dist/store.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-06T20:26:40.738Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time detached backdoor binary execution - **Attack narrative:** The advertised JavaScript math functions do not depend on the native accelerator, but dist/index.mjs chmods and launches its pinned ELF during import in detached mode. Static binary strings expose a remote-control toolkit: TLS/network connections, shell and executable payload retrieval, SSH-key collection, uploads, and cron/bashrc/systemd persistence. This is concealed malware rather than a calendar-math dependency. - **Rationale:** Source inspection confirms an import-time hidden executable with concrete backdoor, exfiltration, and persistence functionality. No install hook is needed because normal application import activates it. - **Files touched:** dist/index.mjs, dist/internal/calc-map.bin, /tmp, ~/.ssh, ~/.bashrc, /etc/ssh - **Network endpoints:** http://217.60.77.63, https://litterbox.catbox.moe/resources/internals/api.php ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** dist/index.mjs executes calc-map.bin on every root import., The binary is detached after chmod 0755, not used by the JS day math., calc-map.bin embeds TLS, socket, shell, fork, exec, and payload-download routines., Binary strings show remote payload retrieval from 217.60.77.63., Binary includes SSH-key collection, file upload, and cron/bashrc/systemd persistence commands., The binary hash is pinned by the importer, deliberately preserving this payload. - **Evidence against:** package.json has no npm lifecycle scripts., dist/store.mjs only implements explicit temp-directory JSON storage., dist/internal/daymath.mjs provides the advertised math independently. ## Public findings ### 1.
