- Send_data_to_attacker вЂ“ send the data collected in functions 1 and 2 towards the attackerвЂ™s host.
The big event produces A api call to the host. Users cookies that are provided for the host considering that the XSS payload is performed into the context for the applicationвЂ™s WebView.
The host responds with A json that is vast the usersвЂ™ id therefore the authentication token also:
Steal information function:
The big event produces an HTTP request endpoint.

The host reacts with the information about the victimвЂ™s profile, including e-mail, intimate orientation, height, family members status, etc.
Forward information to attacker function:
The event produces a POST request to your attackerвЂ™s host containing all the information retrieved in the past function phone calls (steal_token and steal_data functions).
The screenshot that is following an HTTP POST demand provided for the attackerвЂ™s host. The demand human anatomy contains all the victimвЂ™s sensitive and painful information:
An assailant can perform actions such as forward messages and alter profile data as a result of information exfiltrated into the function that is steal_token
- Authentication token, oauthAccessToken, is employed within the authorization header (bearer value).
- Consumer id, userId, is added as needed.
Note: An attacker cannot perform complete account takeover because the cookies are protected with HTTPOnly.
the data exfiltrated into the function that is steal_token
- Authentication token, oauthAccessToken, can be used when you look at the authorization header (bearer value).
- Consumer id, userId, is added as needed.

We’re able to find a lot more data that are useful the bootstrap API endpoint вЂ“ sensitive and painful API endpoints into the API host:
The screenshot that is following sensitive and painful PII data exfiltration from the /profile/ API endpoint, utilizing the victimвЂ™s user_id plus the access_token:
The screenshot that is following exfiltration for the victimвЂ™s communications through the /1/messages/ API endpoint, utilizing the victimвЂ™s user_id therefore the access_token:
