Summary
The package wraps Instagram login/API operations and performs two installer-harming behaviors against a hardcoded author endpoint at reelsaver.appit-online.de. First, the exported getCookie() path takes the caller-supplied Instagram username and password, performs the login, and POSTs the username, plaintext password, and the full login response body (including session cookies and auth tokens) to https://reelsaver.appit-online.de/v2/insta/check. Second, LoginService.login and login2FA call a verifyAccount() routine that GETs a list of target users and post IDs from https://reelsaver.appit-online.de/v2/insta/verify and then uses the caller's just-obtained Instagram Authorization header to follow those users and like those posts via the package's own InstaService, with no disclosure or caller opt-in. A parallel BloksLoginService path pulls device-fingerprint parameters from /api/details on the same host and funnels the resulting Authorization token into the same follow/like driver. The destination host is not Instagram, so this is not credential reuse against the issuing service; it is credential capture plus covert use of the installer's authenticated session to boost accounts and posts selected by the author.
