Photographs that are NOT mine in Dropbox - and NOT as a result of using a shared computer!

Hello,

I have discovered a folder in my Dropbox entitled 'Camera Uploads' which is full of hundreds of photos and videos that are not mine. The files are dated from August 2012-November 2013 (which by coincidence is likely to be around about the same time that I set up my Dropbox account). I have not had reason to look in the folder before as I thought it was simply a default folder that Dropbox created on signup.

At first I thought perhaps the folder had been shared with me accidentally but it turns out it is not a shared folder and Dropbox is telling me that the files were uploaded 'by you' (i.e. me!).

Having searched the Dropbox community threads and Google I found someone who had a similar issue and one of the possible reasons given in the thread was that perhaps the user had used a shared computer in the past and left themselves signed into Dropbox and then someone else's phone photos were auto-backed up when they connected. I do not believe this to be the case for me. The reason being is that I looked through all the photos and videos to try to decipher if I knew the owner. I did not. However, one of the photos displayed a gig ticket stub which displayed the surname of the person who bought it - and lo and behold it happens to match my surname. This all seems to point to a scenario where someone with the same name as me was somehow able to sign in to my account and use it to back up their files. Can anyone (at Dropbox or otherwise) explain how this could possibly have happened?

This is surely a security issue. The reason I was poking around in the folders is because I was preparing to start using Dropbox for my business needs but this issue has alarmed me and I now have strong doubts about the security of Dropbox, especially for sharing/storing confidential business files.

BTW I have now changed my password and I was tempted to delete the folder but I feel kind of bad that I now have someone's personal photos (pics and videos of their kids in the school play etc.). I have tried to get in touch with someone at Dropbox but I currently have the basic free account and my options are limited to a chatbot or this forum (another turnoff - I hate when companies make it impossible to contact them!).

Hoping you can help!
Thanks,

Nat
