  • [ ] Subsidiary and Acquisition Enumeration
  • [ ] Reverse Lookup
  • [ ] ASN & IP Space Enumeration and Service Enumeration
  • [ ] Google Dorking
  • [ ] Github Recon

• Registration Feature Testing
  • [ ] Check for duplicate registration/Overwrite existing user
  • [ ] Check for weak password policy
  • [ ] Check for reuse existing usernames
  • [ ] Check for insufficient email verification process
  • [ ] Weak registration implementation-Allows disposable email addresses
  • [ ] Weak registration implementation-Over HTTP
  • [ ] Overwrite default web application pages by specially crafted username registrations. => After registration, does your profile link appears something as darksideops.com/dark?a. If so, enumerate default folders of web application such as /images, /contact, /portfolio b. Do a registration using the username such as images, contact, portfolio c. Check if those default folders have been overwritten by your profile link or not.”
• Session Management Testing
  • [ ] Identify actual session cookie out of bulk cookies in the application
  • [ ] Decode cookies using some standard decoding algorithms such as Base64, hex, URL, etc
  • [ ] Modify cookie.session token value by 1 bit/byte. Then resubmit and do the same for all tokens. Reduce the amount of work you need to perform in order to identify which part of the token is actually being used and which is not
  • [ ] If self-registration is available and you can choose your username, log in with a series of similar usernames containing small variations between them, such as A, AA, AAA, AAAA, AAAB, AAAC, AABA, and so on. If another user-specific data is submitted at login or stored in user profiles (such as an email address)
  • [ ] Check for session cookies and cookie expiration date/time
  • [ ] Identify cookie domain scope
  • [ ] Check for HttpOnly flag in cookie
  • [ ] Check for Secure flag in cookie if the application is over SSL
  • [ ] Check for session fixation i.e. value of session cookie before and after authentication
  • [ ] Replay the session cookie from a different effective IP address or system to check whether the server maintains the state of the machine or not
  • [ ] Check for concurrent login through different machine/IP
  • [ ] Check if any user pertaining information is stored in cookie value or not If yes, tamper it with other user’s data
  • [ ] Failure to Invalidate Session on (Email Change,2FA Activation)

      • [ ] client_secret → Secret Token known to the Twitter and Twitterdeck to generate access_tokens
      • [ ] response_type → Defines the token type e.g (code, token, etc.)
      • [ ] scope → The requested level of access Twitterdeck wants
      • [ ] redirect_uri → The URL user is redirected to after the authorization is complete
      • [ ] state → Main CSRF protection in OAuth can persist data between the user being directed to the authorization server and back again
      • [ ] grant_type → Defines the grant_type and the returned token type
      • [ ] code → The authorization code twitter generated, will be like ?code= , the code is used with client_id and client_secret to fetch an access_token
      • [ ] access_token → The token twitterdeck uses to make API requests on behalf of the user
      • [ ] refresh_token → Allows an application to obtain a new access_token without prompting the user
