What is Dropbox virus?

Dropbox virus is a term used to refer to different threats that in some way use the name of the legitimate application to perform their malign actions. Dropbox itself is a file hosting application that was developed in 2007 and belongs to the Dropbox Inc. It is a rather popular platform used to store users’ photos, videos, and other files.

What are the types of Dropbox virus?


One of the most serious parasites that can be delivered through spam email attachments is ransomware. Usually these spam emails pretend to come from trustworthy sources, in this case, Dropbox Inc. The fake email claims to contain a voice mail message that includes a malign link. Clicking this links results in users infecting their device with ransomware, which in turn encodes all data files stored on the device. After the encryption, the hackers demand that the user pays a ransom fee stating that that is the only way to make sure the files are restored. In most cases, unfortunately, users lose their files regardless of whether they actually pay or not.

Another malicious program using Dropbox as a way to infect computers is called UPATRE. It disguises itself as an incoming fax report email with a corrupted link. Once the user clicks on the link, he or she starts downloading the harmful .zip and .exe files. UPATRE Trojan is mostly used to drop other parasites onto the device. It is a modified version of Zeus Trojan, so it carries out a lot of the same actions like spying on users, stealing their personal and financial details, and more.

Other Trojans

Please note that there are plenty of other Trojans misusing names of well-known programs including uTorrent, Picasa, Skype, etc. Some of these Trojans pretend to be updater executables and often appear in %AppData% folder. They are all capable of downloading malicious files from the Dropbox service.


Another threat that must be mentioned is a phishing scam that sends out fake emails about urgent orders. The message looks like this:


We want to place an urgent order this month.

Kindly check the attached file if you can supply this exact product

or let us know if you have similar model.”

The email contains an attached file clicking on which reroutes you to a fake Dropbox login page. If you type in your account details or any other private information, you disclose it to cyber crooks. Needless to say, this information can and most likely will be misused later on.


TrickBot is a banking Trojan distributed through fake Dropbox emails. It is known for launching malign campaigns against major finance companies like PayPal and some others. The threat spreads in a similar manner to other malware already mentioned here: it attaches a corrupted document  that contains a malicious payload to a spam email.

Amendment or Agreement_[date] malware sent through spam emails that state that a file has been shared with you by an unfamiliar person . If you click on the “Click here to view” button, you will download the Amendment or the Agreement_[date].zip file that will then drop the Agreement _[date].scr on your computer.

How to avoid Dropbox virus?

In order to avoid infecting your device with Dropbox virus or any other parasite, you have to make sure that you do not interact with any suspicious content. Cyber criminals use names of well-known organizations to try to trick users into thinking that they are dealing with real messages. These emails usually contain corrupted links or attachments clicking on or downloading which results in malware infection. Therefore, it is very important to be extremely cautious with your email correspondence. If you see messages in your spam folder, it is better to delete them without even opening them.

Moreover, if you are dealing with an email that contains an attachment, you have to be even more careful: always scan the attachment (regardless of whether it is a Word document, PDF file, or any other file type) with an anti-malware utility to make sure that it is not a harmful intruder.
