Instagram account hacked - how?

Question

Instagram

The girl complained today. She uses Instagram only on iPhone (she still logged in through the browser). I can't log in in the morning... the passwords don't work.
comes through Facebook - all contact info and mail has been changed. we change it back to ours, change passwords, change passwords at the mail, make a confirmation. seems to be ok. a couple of hours pass - the account has completely evaporated, when you try to restore mail, it gives out an attacker.
how is that at all? I wrote to them, I hope the issue will be resolved ...

Answer 1

when trying to restore mail, it gives out an attacker.

So grab it and the competent authorities :)
- We look at the "security question" in the mail. Maybe everyone knows the name of the owner's dog.
- Let's get into the mail settings. We are looking for the line "duplicate mail to the address:" or something similar
- We are looking for trojans, keyloggers, other systems for monitoring user actions.

Answer 2

1. It is necessary to bind not only to FB and email, but also to a phone number.
2. Now write to support. After 3-7 days they will reply and ask you to send a photo of a girl with a code written on a piece of paper, which they will ask you to write. This is necessary to confirm that the girl is the real owner. After that, everything will be restored.
PS: if all the photos are taken down, then there is a possibility of restoration.
