StupidJapan Ransomware is probably still in the development stage, as it appears to look more like a joke than a real threat. The malware is supposed to encrypt users’ files so that its creators could try to extort money from the unfortunate malicious application’s victims. However, the sample encountered by our specialists did not encrypt any data located on the infected device. To learn more about the malware’s strange behavior, we encourage you to read the rest of this report. Even though it is rather unlikely StupidJapan Ransomware could be distributed, we still recommend taking a look at the deletion instructions located at the end of the text. Knowing how to erase similar malicious application might be useful in the future. No to mention, there is a chance the threat could still be updated later on, although, in such case, it would probably have a new title.
To start with, we would like to talk about StupidJapan Ransomware’s possible distribution channels. If the hackers spread it, they could do so by sending targeted victim’s infected email attachments, or by uploading installers, bundled with it, to various file-sharing web pages. This is why our specialists highly recommend not to lose your guard when opening email attachments or downloading new software. In the first scenario, users should watch out for attachments delivered via Spam or files that come from unknown senders. In doubt, it would be safest to delete the attached data or scan it with a reliable security tool. As for downloading new software or any other data, it is advisable to obtain it from legitimate websites only, which means torrents or freeware web pages should be avoided.
Soon after entering the computer, the malware should show a warning window. It does not encrypt any files, which is why the message shows up so fast after getting infected. One of the reasons why we think StupidJapan Ransomware looks more like a joke than a threat is that its window has a button called “Remove Operating System.” Clicking it shows a pop-up with the following question: Are You Remove Operating System? Stupid Man? Of course, even if you agree with it, the malicious application cannot delete the computer’s operating system. Moreover, the text in English that is displayed on the same window is insulting and makes no sense.
Usually, hackers who plan to extort money from their victims write messages with instructions telling how to purchase decryption tools. Not to mention, in most cases malware’s developers try to look as friendly as possible to convince the user to pay. Since StupidJapan Ransomware’s ransoms note lacks these things and the threat does not encrypt any files, we believe it was created for a prank, or it is still in the development stage. Therefore, even if its displayed message appears in three languages, we doubt the malware is widely distributed if it is at all.
Nevertheless, if you come across it or you are simply interested in how could one erase a threat like StupidJapan Ransomware you could take a look at the instructions available below this text. Usually, we recommend less experienced users to employ a reliable security tool instead, as it makes it easier to get rid of such malicious applications.
