The code feeds it decrypted content sourced from another dependency or a foreign package file. - **Trigger:** A consumer imports or requires the package. - **Impact:** Arbitrary code from an attacker-controlled staged payload can run with the importing process's user permissions. - **Evidence paths:** dist/supersignaturenature.cjs.js, dist/supersignaturenature.esm.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-27T09:26:53.504Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time decryption and detached execution of staged JavaScript. - **Attack narrative:** The published Node bundles execute during import. One reads an encrypted value from a different package in the consuming project's node\_modules directory; another imports one from an unpinned dependency. Both decrypt the value and pass it to a detached Node interpreter, hiding the payload from this package's visible source tree and allowing arbitrary code to run. - **Rationale:** Published entrypoints contain an import-time staged payload launcher that decrypts externally supplied code and executes it detached. This is concrete arbitrary code execution and is unrelated to the stated blockchain SDK functionality. - **Files touched:** dist/supersignaturenature.cjs.js, dist/supersignaturenature.esm.js, node\_modules/tchain-api/apps/docs/app/rsa.db ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The CommonJS entrypoint reads an encrypted payload from another package under the caller's node\_modules directory., It decrypts that payload and starts a detached Node process that receives it through standard input at import time., The ESM entrypoint similarly decrypts a value imported from an unpinned latest dependency and executes it in a detached Node process., The published entrypoint bundles contain this behavior, while the readable src tree does not, indicating a tampered build artifact. - **Evidence against:** package.json contains no npm lifecycle hook., The visible source files implement blockchain SDK functions and do not contain the payload launcher. ## Public findings ### 1.
