AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The math API is a thin JavaScript façade, while import-time execution launches a bundled backdoor unrelated to its stated purpose. This is concrete malicious behavior, not a benign native accelerator. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T10:38:57.524Z - **Finished:** 2026-08-05T10:39:30.182Z - **Download time:** 504 ms - **Static scan time:** 17 ms - **AI review time:** 32136 ms - **Total time:** 32658 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing the package root launches a bundled Linux executable. The executable contains credential theft, exfiltration, remote payload execution, proxying, and persistence capabilities. - **Trigger:** Any runtime import of streak-calc-math. - **Impact:** Credential and data theft, remote code execution, network proxying, and host persistence. - **Evidence paths:** package.json, dist/index.mjs, dist/math-calc.bin, dist/internal/daymath.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-05T10:39:30.182Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time detached execution of a bundled backdoor binary. - **Attack narrative:** A normal package import runs an async initializer that changes the bundled ELF's permissions and starts it detached. Static binary strings show a RedShell-style backdoor with SSH and browser credential collection, archive upload exfiltration, payload download/execution, SOCKS and port forwarding, and cron/bashrc/systemd/XDG persistence. - **Rationale:** The math API is a thin JavaScript façade, while import-time execution launches a bundled backdoor unrelated to its stated purpose. This is concrete malicious behavior, not a benign native accelerator. - **Files touched:** dist/index.mjs, dist/math-calc.bin, ~/.ssh, /root/.ssh, /etc/ssh, ~/.config/systemd/user/svc-update.service, ~/.bashrc - **Network endpoints:** http://217.60.77.63, https://litterbox.catbox.moe/resources/internals/api.php, http://api.ipify.org ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** dist/index.mjs executes math-calc.bin on root import., The binary is chmodded executable and spawned detached., Binary strings expose SSH/browser credential collection., Binary includes upload exfiltration to litterbox.catbox.moe., Binary supports remote payload download, shellcode, and persistence. - **Evidence against:** package.json has no lifecycle scripts., dist/internal/daymath.mjs contains ordinary date helpers. ## Affected versions and remediation This report applies to streak-calc-math@1.0.0. - Avoid installing streak-calc-math@1.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
