Account Takeover Methodology

1.I have added a session hijacking method in broken authentication and session management. 
2.If you find that on target.
3.Try anyway to steal cookies on that target.

Password Reset Poisioning Leads To Token Theft

1.Go to password reset funtion.
2.Enter email and intercept the request.
3.Change host header to some other host i.e,
    Host:target.com
    Host:attacker.com
  also try to add some headers without changing host like
    X-Forwarded-Host: evil.com
    Referrer: https://evil.com
4.Forward this if you find that in next request attacker.com means you managed to successfully steal the token. :)

Using Auth Bypass

Check out Auth Bypass method, there is a method for OTP bypass via response manipulation, this can leads to account takeovers.
1.Enter the wrong auth code / Password
2.Capture a auth request in burpsuite and send it to repeater 
3.Check for the resoponse
4.Change the respone by manipulating the following parameters
  {“code”:”invalid_credentials”} -> {“code”:”valid_credentials”}
  {“verify”:”false”}             -> {“verify”:”true”}
