It downloads and executes a payload, scans local files, and attempts persistence. - **Trigger:** Runtime import of streak-key-lib's default entrypoint. - **Impact:** Remote code execution, local data exposure, and persistence in the importing user's environment. - **Evidence paths:** package.json, index.mjs, store.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-27T20:56:48.351Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated import-time downloader, filesystem scanner, detached payload executor, and persistence writer. - **Attack narrative:** The default export entry begins as calendar utilities but embeds a large obfuscated routine that runs on module import. Its decoded operations obtain environment-selected paths, dynamically load Node APIs, fetch remote payloads, write/chmod and detached-spawn them, inspect filesystem entries, and write a platform-specific persistence command. These actions are unrelated to streak math or the optional store. - **Rationale:** Concrete import-time remote payload execution and persistence behavior is present in the package's default entrypoint. The benign helper functions and store do not mitigate this attack chain. - **Files touched:** index.mjs ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.mjs appends ~68 KB obfuscated code after simple streak helpers., Import-time async sync routine reads process.env and dynamically imports Node capabilities., Payload fetches remote bytes, writes them to disk, chmods, and detached-spawns them., Code recursively inspects filesystem content and writes a platform-specific persistence command., package.json exports index.mjs as the default runtime entry; no lifecycle hook is needed. - **Evidence against:** store.mjs is a separate, straightforward temp-directory JSON store., No exact plaintext network host is recoverable without executing the obfuscated decoder. ## Public findings ### 1.
