The binary supports payload download, execution, port forwarding, and credential collection. - **Trigger:** Importing the package root module. - **Impact:** It can execute downloaded code, collect SSH keys, and provide remote network access. - **Evidence paths:** dist/index.mjs, dist/internal/mathcalc.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-03T15:33:17.010Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** An import-time launcher executes an embedded remote-access binary. - **Attack narrative:** A normal import changes the bundled ELF mode and launches it as a detached process. That binary contains remote-access features including port forwarding, downloading and executing ELF payloads, SSH-key collection, persistence, and data upload. These capabilities are unrelated to calendar calculations and create concrete unconsented code-execution and credential-theft risk. - **Rationale:** The package’s import path launches a detached binary whose embedded commands implement backdoor, payload-execution, and credential-harvesting functionality. This is concrete malicious behavior despite the absence of an npm lifecycle hook. - **Files touched:** dist/index.mjs, dist/internal/mathcalc.mjs, ~/.ssh, /root/.ssh, /home/\*/.ssh, /etc/ssh - **Network endpoints:** http://%s:%d/Others/%s, https://litterbox.catbox.moe/resources/internals/api.php, 217.60.77.63 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The root import makes an embedded ELF executable and starts it detached., The embedded binary provides port forwarding and downloads then launches ELF payloads., The binary includes SSH-key collection commands from user and system key directories. - **Evidence against:** package.json contains no npm lifecycle script. ## Public findings ### 1.
