onedrive_user_enum v2.10

enumerate valid onedrive users

For a full rundown of the enumeration technique and OneDrive enum, check out the blog here:

https://www.trustedsec.com/blog/onedrive-to-enum-them-all/

New features in 2.10:

• Remote MySQL DB logging option -- log to a remote database
• PAUSEFILE -- if pausefile is present (/tmp/PAUSEFILE), pause enumeration
• Truncate userlist to x characters -- johnsmith -> johnsmi

New features in 2.00:

• Local Database (sqlite3)
• Auto-lookup of tenants (thanks @DrAzureAD and @thetechr0mancer)
• Read in file OR folder of files
• Append -- easily create 'jsmith1' 'jsmith2' sprays
• Skip-Tried (de-dupe) -- remove previously tried usernames
• Kill-After -- cancel a userlist if no usernames identified within 'x' attempts

OneDrive Enumeration overview:

OneDrive users have a file share URL with a known location:

https://acmecomputercompany-my.sharepoint.com/personal/lightmand_acmecomputercompany_com/_layouts/15/onedrive.aspx

In this instance, the username is 'lightmand' and the domain is 'acmecomputercompany.com'. If a user has logged into OneDrive, this path will exist and return a 403 status code. If they have not, or the user is invalid, it will return a 404.

The results may vary depending on how widely used OneDrive is within an org. Currently it is the most reliable user-enumeration method that I'm aware of (office365userenum no longer works, and the others like UhOh365 are unreliable). Further, it does not attempt a login and is much more passive, and should be undetectable to the target org. Microsoft will see the hits, but the target org won't.

usage:

 # ./onedrive_enum.py -h
