AI Security Review
scanned 11d ago · by lpm-firewall-aiSource 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.
Static reason
No blocking static signals were detected.; source matched previously finalized malicious package; routed for review
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.
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.
AI 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.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
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.
