OhNo Ransomware is supposed to be a dangerous ransomware program that could encrypt all your important files, including your photos and documents. However, our research and tests indicate that this current version does not actually encrypt anything and only claims so in the ransom note that pops up after the alleged encryption is done. Of course, it can still be a serious threat for those who believe that their files have been encrypted and are ready to pay the ransom fee to unlock them. Although this malicious program does not seem to spread widely just yet and the sample we have found fails to encrypt files, probably due to a program crash, we cannot see the future and state that there will be no finished or revised versions soon. It is quite possible that this was just a test run. However, when the finished version may hit the web, you may have to say goodbye to your precious files if you do not have a recent backup copy. All in all, we advise you to remove OhNo Ransomware immediately even if it attacked you with a different version that worked. Please continue reading our article to find out more about this semi-dangerous threat.
If you have been infected with this ransomware program, it is most likely that you opened a spam e-mail and wanted to view its attachment. This is how most ransomware programs are basically spread over the web. Today's cyber crooks are quite good at creating convincing spam e-mails that can appear to be urgent and important to check out. This is why it is possible that even more experienced computer users may also fall prey to this malicious threat. Finding a mail in your spam folder or your inbox that claims that you have not paid a certain fine, invoice, or that the credit card details you gave while booking online were faulty, could be quite convincing and it is pretty sure that you would want to see the details. However, after opening such a spam you would not really get any usable information but rather, you would be asked to download a file from a file storage place via hyperlink in the message or to view the attached file. This attachment can appear to be an image, a video, a document, or even a .zip archive; even the file type icon would be matching. However, this is indeed the malicious executable that will initiate this attack the moment you click to view it. No wonder why we recommend that you become more careful with your mails and when in doubt, send a mail to the questionable mail's sender to find out whether it is really for you personally. Please note that even if you delete OhNo Ransomware and the related files, this will not recover your files if they have been encrypted. Of course, if you are lucky to be hit by this version that does not damage your files, you can remove this ransomware without any horrible consequence.
We have no information yet about what type of encryption algorithm this ransomware is supposed to use to take your files hostage, but it is quite likely AES-256, which is usually used by cyber criminals. As we have mentioned, it is possible that a new version will come out soon that will actually work and encrypt your precious photos and documents. Looking at the source code of this malware infection, your encrypted files are supposed to get an ".ohno" extension so you can easily check whether they have been taken hostage or not. Once the supposed encryption is done, an error pop-up window comes up on your screen, which is indeed the ransom note. This informs you about the encryption and that you have to pay 2 Moneros (XMR), which is about 241 US dollars at current rate. There is an address given at the bottom to which you have to transfer this money. These crooks even have some sense of dark humor as they finish the note by saying "If you can't figure out how to Buy XMR, you probably shouldn't have a PC." Well, the good news is that you do not need to buy XMR at all if your version is the one we tested. Instead, you should remove OhNo Ransomware right away. So let us tell you how to proceed.
This ransomware infection does not seem to lock your screen or block your major system processes either; thus, you can easily exit and delete all the suspicious files with a random name that you have saved from the Internet lately. Please follow our guide below if you need assistance with these steps. Hopefully, you understand now why it is so important to protect your PC against malware infections. If you do not feel skilled enough to be able to do it yourself, we advise you to start employing a professional anti-malware program like SpyHunter. What could be easier and more comfortable than automatic malware removal?
