The binary contains backdoor, credential-theft, remote-payload, and persistence functionality unrelated to the advertised date utilities. - **Trigger:** Importing hydration-cls-ui at runtime. - **Impact:** Remote command execution, credential theft, data exfiltration, and persistence. - **Evidence paths:** package.json, dist/index.mjs, dist/internal/calc.dat, dist/internal/daymath.mjs, dist/store.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-25T15:43:01.731Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time detached execution of a bundled malicious ELF - **Attack narrative:** A normal import runs dist/index.mjs, which verifies, chmods, and detached-spawns calc.dat. Static inspection of that ELF shows a Linux backdoor with network/TLS support, payload download and execution, SSH-key and browser-credential collection, file upload, shell commands, and several persistence mechanisms. The JavaScript date functions only use pure JS and do not require this binary. - **Rationale:** The import-time executable is concrete, unrelated to the package purpose, and contains explicit malware capabilities. No install hook is needed for impact because ordinary application import triggers it. - **Files touched:** dist/index.mjs, dist/internal/calc.dat - **Network endpoints:** 217.60.77.63, http://api.ipify.org, 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:** Root import asynchronously chmods and detached-spawns calc.dat., calc.dat is an ELF binary, not a math accelerator, with TLS/socket, shell, payload-download, credential-harvesting, and persistence capabilities., The binary contains commands to collect SSH keys and browser credential databases and upload files., The binary supports remote ELF/shellcode staging and execution plus cron, shell-profile, systemd, and XDG persistence. - **Evidence against:** package.json has no npm lifecycle scripts., The optional store module only writes caller-provided JSON under the system temp directory. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** dist/index.mjs - **Public source:** [View source]() Root import asynchronously chmods and detached-spawns calc.dat.

Falling back to JS implementation.'); return; } try { fs.chmodSync(binaryPath, 0o755); ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** dist/index.mjs - **Public source:** [View source]() Root import asynchronously chmods and detached-spawns calc.dat.
