An MSF module for dropbox detection. This can complement nmap or orther port scanning software.
Clone this file:
git clone https://github.com/dagorim/msf_dropbox_scanner.git
Create a folder under your MSF custom module directory:
mkdir /root/.msf4/modules/auxiliary/scanner/misc/
Copy the file downloaded from step one into the directory from step 2:
cp msf_dropbox_scanner/dropbox.rb /root/.msf4/modules/auxiliary/scanner/misc/
Now you can search for and use the module from within Metasploit:
msf> use auxiliary/scanner/misc/dropbox
