If you haven’t heard it already, there is a massive ransomware outbreak. Bad Rabbit Ransomware is responsible for computer infections in Ukraine, Russia, Turkey, Bulgaria, and Germany. If you have detected the WINDOWS\INFPUB.DAT file in your system, we have bad news for you. Your computer has fallen victim of Bad Rabbit Ransomware. WINDOWS\INFPUB.DAT is the main module of the virus. It is located in your C:\Windows directory. It is run by the rundll32.exe and is used to scan devices connected to your Local Network. This function is still under development. It will probably be used in future versions of the virus. It is hard to say what the hackers plan. WINDOWS\INFPUB.DAT is probably part of not yet developed Bad Rabbit distribution method. At this point, we can only speculate. Nevertheless, the existence of WINDOWS\INFPUB.DAT on your computer is a sign that your machine is infected. Even now, as you read this article, the ransomware is working in the background. Bad Rabbit is lurking in the shadows and wreaks havoc. Once on board, it drops the INFPUB.DAT files as well as the main DLL and two malicious apps. These four elements work together to lock your files. Bad Rabbits cans your HDD. It targets user-generated data such as your pictures, videos, music, documents, databases, etc. Then, it encrypts them with an unbreakable cipher. Only after the completion of the encryption process, will the ransomware reveal itself. It drops its ransom note, which demands 0.05 BTC (about $289 USD). Whatever you do, don’t rush. Bad Rabbit is a descendant of the dreaded NotPetya (Petya) Ransomware. There are notable differences between the two, however, they are equally destructive. Both viruses are probably created by the same hackers, too. However, unlike Petya, the hackers behind Bad Rabbit can reverse the encryption. In exchange for a hefty sum, of course. We recommend against paying the ransom, though. You are dealing with cybercriminals. You cannot expect them to keep their part of the deal.
How did I get infected with?
The existence of WINDOWS\INFPUB.DAT on your PC means that Bad Rabbit has successfully installed itself. The question is: how did it manage to enter your machine unnoticed? One key difference between Bad Rabbit and NotPetya is that Bad Rabbit relies on your naivety. This virus cannot infect our computer without your “help.” The virus employs a lot of trickery. The scheme is not that inventive, yet, quite effective. One way or another, you end up on a website that states that your Flash is outdated. In order to view the content on the page, you must update your software. You click on the provided link and download the update (file install_flash_player.exe). So far, so good. Then, you execute the file. And this is the exact moment you gave the virus admin privileges. From this point onward, it can do whatever it is programmed to do and you can’t do anything about it. Smart, isn’t it? Yet, Bad Rabbit does not rely only on this distribution method. It is also spread via phishing emails. The scheme is the same. You download the corrupted file. You execute it. And that’s it. A little extra caution, however, could have prevented this infection! Learn your lessons. Don’t repeat the same mistake again!

Bad Rabbit may re-encrypt your newly restored files. How many times do you plan to pay for your files? The answer should be “None.” You are in a bad, bad situation.
