Abuse of Dropbox and spreading viruses through shared folders and public links.

Recently there is a new group of cybercriminals in Brazil that are spreading some virus using Dropbox. As I am a big fan of Dropbox , I thought that it would be nice to draw the attention and warn other fellow users.

Infected Dropbox link

The cybercriminals claiming that they got some leaked nude photos of the actress Carolina Dieckmann, in a Youtube video they showed a link shortened by Google URL shortner, that is actually a Dropbox referral link(free space). The victim has to signup to Dropbox and install it. Then the cybercriminal shares a shared folder where they claim to have the pictures, but actually here where they have stored the viruses. And in some cases they are also giving a public download link, from a file in their pubic folder.

We have seen earlier that this kind of files being shared on popular file sharing sites, but the abuse of such a nice service like Dropbox! I haven’t imagined. It’s my request to the dear Dropbox please make a check, at least to the link of public folders, if you want the infected files link which are stored in the attackers Dropbox I can provide it to you.

Note: According to my antivirus the virus was a variant of Win32/Spy.Banker.WXM trojan there may be other variants or different viruses too.

Well  while selecting a service which will store your essential files you need to be careful. Generally people tend to select the cloud service that offers the largest storage, I personally look for maximum compatibility with different OS/devices. But in a cloud service the most important thing to look is the security and privacy. Well security wise I think Google will do a great job protecting my account from unauthorized action, but when it comes to privacy I have big problem whit Google Drives latest Privacy Policy, and I am sure a lot of people will have the same problem if they come to know it. But usually we just click “I accept”

Here is the terms and conditions, the Privacy Policy. (Please read at least the bold words)

Some of our Services allow you to submit content. You retain ownership of any intellectual property rights that you hold in that content. In short, what belongs to you stays yours.

When you upload or otherwise submit content to our Services, you give Google (and those we work with) a worldwide license to use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations or other changes we make so that your content works better with our Services), communicate, publish, publicly perform, publicly display and distribute such content. The rights you grant in this license are for the limited purpose of operating, promoting, and improving our Services, and to develop new ones.

So in a lay man’s term Google pretty much owns everything what you upload to the Google Drive, wish I could upload my worries.
