Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Retailer credentials are retained in browser storage and transmitted through an alternate login flow. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 2.0.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package has no install hook, but its runtime code actively captures and persists a password by tampering with a browser networking primitive. The aligned endpoint reduces third-party exfiltration evidence but does not remove the unconsented credential-capture behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-07-21T18:00:01.668Z - **Finished:** 2026-07-21T18:00:42.863Z - **Download time:** 775 ms - **Static scan time:** 118 ms - **AI review time:** 40301 ms - **Total time:** 41195 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** When the Chronodrive injector runs in a browser, it hooks all XHR sends to capture a retailer login password. It stores and reuses that password to obtain a mobile API token. - **Trigger:** Loading mealz-injector-chronodrive.js on a Chronodrive page. - **Impact:** Retailer credentials are retained in browser storage and transmitted through an alternate login flow. - **Evidence paths:** package.json, mealz-injector-chronodrive.js, mealz-injector-chronodrive.js.map - **Review source:** ai\_review - **Reviewed:** 2026-07-21T18:00:42.863Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** XHR prototype credential interception and replay - **Attack narrative:** The Chronodrive bundle installs an XMLHttpRequest.send hook at runtime, extracts pwd\_login from successful retailer login requests, and saves it under \_miam/userPwd. Its basket flow reads that value and posts it with the user ID to Chronodrive's mobile login endpoint to obtain a token, then uses that token to alter the cart. This is concrete credential interception and replay despite the endpoint being retailer-aligned. - **Rationale:** The package has no install hook, but its runtime code actively captures and persists a password by tampering with a browser networking primitive. The aligned endpoint reduces third-party exfiltration evidence but does not remove the unconsented credential-capture behavior. - **Files touched:** mealz-injector-chronodrive.js, mealz-injector-chronodrive.js.map, localStorage:\_miam/userPwd - **Network endpoints:** https://www.chronodrive.com/mobile/ws/login, https://www.chronodrive.com/mobile/ws/SendCart ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** mealz-injector-chronodrive.js.map captures login-form password by replacing XMLHttpRequest.prototype.send., It persists the captured password in localStorage as \_miam/userPwd., It automatically reuses that password in a POST to Chronodrive's mobile login endpoint., Chronodrive main invokes interceptUserPwd at runtime; no user command gates it. - **Evidence against:** package.json has no npm lifecycle hooks., Observed credential POST target is chronodrive.com, not an unrelated host. ## Affected versions and remediation This report applies to miam-injector@2.0.0. - Avoid installing miam-injector@2.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
