​bugbountytip: if a website does not verify email, try signing up with <whatev>@domain.com (the company email). Sometimes this gives you higher privilege like deleting/viewing any other user's profiles etc.​

​Do you have any problem with creating a new account in some application due to requirement of business email (corp)? Solution is here: #Burp Collaborator. Create an account with [email protected] and look after SMTP request at your client. #Security #bugbountytip #webapp​

​Just found an interesting bug.. can you invite other users (via email usually) to xyz? Try the invite link on a different account and see what happens. In my case, it auto leaked my other accounts email to me. (no prompts to accept invite, didn't validate user) #BugBountyTips​

​#bugbountytip If you can send letters from your email [email protected], try to substitute your email with company employers or other users email in the request. You can find it with http://hunter.io or reg another acc. For me, it worked a few times in private BB.​

​#BugBountyTip: Always remember to check emails for access control issues. Sometimes the same access control is not applied when sending emails. [email protected] for the bounty!Quote Tweet​
