The information contained here will help you gain better insight into the issue you’re dealing with and the ways in which you can protect yourself from its kind in the future.

What are Trojans used for?

One of the key traits of Trojans in general is that they are multipurpose tools that can be used for a variety of harmful activities. You are probably keen on knowing the exact purpose of the Bluber.A worm on your machine, and though we cannot tell you that for certain, we can outlines the most common usages for these particular virus types.

  • Trojans are often used for the purpose of corrupting or deleting data on the victims’ computers. This can be done by a variety of means and for even more purposes, like professional reasons, such as the competition trying to get rid of valuable information that you may be in possession of. In fact, a Trojan may easily format all your disks and drives, wiping them clean of everything you had stored on them.
  • Spying and theft. Trojans like Win32/Bluber.A can act as the eyes and ears of hackers on your PC. They can tap into your webcam, as well as your microphone to watch you and listen to your remotely. That way the criminals behind Bluber.A worm can gain an understanding of your surroundings, gather personal and professional information about you or simply anything that may give them an advantage over you. This could be done for purposes of stalking – there are enough crazies out there. Alternatively, your home may be monitored as a subject of a potential robbery; you yourself may fall victim to some physical crime. These are all very serious potential consequences, which are not to be taken lightly.
  • Resource abuse. A Trojan horse virus like Win32/Bluber.A can also be planted in your machine with the intent of using your PC’s resources for whatever purpose. For example, your computer may be involved in botnets and used to distribute spam or infect other computer within its network. This may seem rather unlikely to you, but you should now that roughly 15% of all computers worldwide are actually used as bots – that’s a considerable number if you think about it. Another potential reason may involve mining cryptocurrencies and sending them to the hackers behind the virus. Bitcoins, for example, have become a fairly weighty online currency that is gaining ever more popularity.
  • Backdoor for other malware. Trojans can easily serve as the ‘middle man’ between you and other viruses, such as ransomware. It can first invade your machine to then download the other virus onto it.

Where can you get a Worm from?

The distribution tactics for Trojans are just as diverse as their uses. Social engineering is a common means of tricking people into downloading viruses like Win32/Bluber.A and others onto their machines. In the case of this malware type specifically, spam emails are arguably the most successful distribution method. They can be disguised as messages from well-known companies and online vendors or even utility companies. There will often be some form of attachment in the email, or a hyperlink, and the mail will be prompting you to either download and open the attachment or follow the link. Furthermore, you may also run into Win32/Bluber.A on some shady and suspicious-looking website. It can be either hidden in some form of downloadable content, such as a torrent file, a game, a movie, etc. Alternatively, you may find it embedded in an online advertisement, like a popup or a banner. We call those malvertisements and by clicking on one of them you will automatically download the malware that was injected in it.
