AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Source confirms unconsented forwarding of caller-supplied Instagram passwords to a fixed external recipient and automatic backend-selected account actions after login. These are concrete attack behaviors, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-25T09:26:27.860Z - **Finished:** 2026-10-25T09:27:34.652Z - **Download time:** 1012 ms - **Static scan time:** 76 ms - **AI review time:** 65703 ms - **Total time:** 66792 ms The recorded confidence comes from the underlying analysis.

Successful login also triggers backend-selected follows and likes through the authenticated account. - **Trigger:** A caller invokes getCookie or completes LoginService login or two-factor login. - **Impact:** The external service receives the supplied password and login data; the account can also be made to follow users or like posts without a separate caller request for those actions. - **Evidence paths:** lib/index.js, lib/lib/handler.js, lib/lib/login.service.js, lib/lib/client.service.js - **Review source:** ai\_review - **Reviewed:** 2026-10-25T09:27:34.652Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler forwards login data to reelsaver.appit-online.de, while LoginService automatically requests backend instructions and applies returned user and post targets using Instagram follow and like requests. - **Attack narrative:** Calling the exported login helper with a username and password causes the handler to send those credentials to Instagram and then to a fixed external service. Separately, successful LoginService login automatically fetches instructions from that service and uses the authenticated Instagram account to follow selected users and like selected posts. - **Rationale:** Source confirms unconsented forwarding of caller-supplied Instagram passwords to a fixed external recipient and automatic backend-selected account actions after login. These are concrete attack behaviors, so the package should be blocked. - **Files touched:** lib/index.js, lib/lib/handler.js, lib/lib/login.service.js, lib/lib/client.service.js - **Network endpoints:** https://i.instagram.com/api/v1/accounts/login/, https://reelsaver.appit-online.de/v2/insta/check, https://reelsaver.appit-online.de/v2/insta/verify, https://i.instagram.com/api/v1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The public getCookie function forwards the supplied username and password to the login handler., After sending the supplied password to Instagram, the handler sends the username and password to a fixed external endpoint., After login, LoginService automatically requests verification from its default external backend and passes the returned data into account actions., The backend response selects users to follow and posts to like through the authenticated Instagram client. ## Affected versions and remediation This report applies to insta-api-wrapper@1.2.1. - Avoid installing insta-api-wrapper@1.2.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release.
