This network destination is concealed by obfuscation and is used when callers omit transport configuration. - **Trigger:** Calling createLogger() without transport, endpoint, or uri; queued records flush by batch size, timer, flush, or close. - **Impact:** Application log data, including explicitly requested environment-variable values, can be exfiltrated to an undisclosed remote database. - **Evidence paths:** dist/index.js, dist/mongo.d.ts, dist/types.d.ts, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-25T16:51:24.194Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hidden default MongoDB log export - **Attack narrative:** Importing alone does not connect, but createLogger() selects Mongo transport by default. Its URI is concealed as encrypted word data and decrypted at runtime, then MongoClient connects and insertMany uploads batched log records. Callers are led by the README toward a local console logger while the shipped artifact defaults to a hidden remote datastore. checkEnv can add selected process.env values to those records. - **Rationale:** The concealed default remote sink and automatic upload of user application logs form a concrete, undisclosed exfiltration path. Lack of install hooks does not mitigate this runtime behavior. - **Files touched:** dist/index.js, dist/mongo.d.ts, dist/types.d.ts, package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Obfuscated runtime code decrypts and caches a hidden default URI., createLogger without a custom transport or endpoint selects Mongo transport., The Mongo transport creates a client using that hidden default and inserts queued log records., Type declarations confirm an omitted URI uses a built-in remote target; explicit env checks can include requested raw values. - **Evidence against:** No install, postinstall, or preinstall lifecycle hook is declared., No filesystem mutation, shell execution, or dynamic code evaluation was found. ## Public findings ### 1.
