Someone opened some old cryptocurrency files on my Dropbox, how?

Hello,

 

As you can see from this screenshot, someone opened some files in my Dropbox, all these being old cryptocurrency wallets (there was nothing inside fortunately).

If I check from the device log (settings-security-devices) I am the only one logged into Dropbox, from my desktop and from my Pixel phone. The last activity from my Pixel phone is set as 22h ago, same as the time these wallets have been opened. 

 

Now: I know for sure that I didn't open any of these files since I even forgot that I have them. And I don't have any cryptocurrency app on the phone that is connected with these wallets. 

How do I find out who and how they opened these files?

 

PS: I have 2fa activated on Dropbox since many years. No one has physical access to wither my desktop nor my phone.

  • Hi fuserr, I just sent you an email, and I'll be happy to see you there!

    Here are the 4 Apps with permission in my account, nothing seems like a security threat:

    Hi fuserr, thanks for bringing this to our attention.

     

    This could mean that an app on your machine might have tried to access those files, not necessarily open them, so it could've been a security program or antivirus. 

     

    Is it possible that you might any apps or services that might monitor the Dropbox folder on your computer?

     

    This will help me to assist further!

      I had only windows defender and now installed Malwarebytes to run a scan but nothing is found. How should I proceed? 

       

      The 3 files that have been "opened" and I have nothing to with it are all 3 files that have to do with wallets, cannot be a coincidence. Of all thousands of files I have in my dropbox...

        Hi fuserr, I see what you mean, but based on all the info you've provided (2fa & recent activity which doesn't seem to be from anyone else) I wouldn't worry. 

         

        You can also have a look at your events page. The Events page at www.dropbox.com/events gives you an overview of all activity in your account including files events (adds/edits/deletes).

         

        I also think this has to do with what my colleague, Jay mentioned and that the files were not actually accessed by someone else. 

         

        However, you can always try changing your password as a security measure.
