Brute force

We can instead try to use custom tools such as o365spray or MailSniper for Microsoft Office 365 or CredKing for Gmail or Okta. Keep in mind that these tools need to be up-to-date because if the service provider changes something (which happens often), the tools may not work anymore

$ python3 o365spray.py --spray -U usersfound.txt -p 'March2022!' --count 1 --lockout 1 --domain msplaintext.xyz
