OhNo Ransomware

What is OhNo Ransomware?

OhNo Ransomware is a very suspicious infection that, at the moment, does not seem to fulfill its potential. In the future, this threat could become a serious file-encrypting threat, but, at the moment, the worst it can do is show a notification demanding a ransom in return of the so-called “Unique Key” that, supposedly, is the only thing that can get your files decrypted. If your files are encrypted, unfortunately, this key might be the only thing that could save them; however, you need to keep in mind that it is held hostage by cyber criminals, and they are unlikely to keep their promises even if you follow their demands. At the time of research, they demanded a ransom of 2 XMR/Monero. Monero is a crypto-currency similar to Bitcoin, a currency used by most ransomware creators. In the past, we have seen at least one other file-encryptor to use Monero, and it was called “Kirk Ransomware.” Needless to say, both of these threats deserve removal, but in this report, we focus on showing you how to delete OhNo Ransomware. Of course, our Anti-Spyware-101.com research team also reveals interesting information about this threat.test

How does OhNo Ransomware work?

If your operating system got infected by OhNo Ransomware, it is most likely that you executed the launcher of this malicious infection without realizing it after opening a corrupted spam email attachment. Of course, other methods of distribution could be employed, but right now this is the most probable one. Once the infection is executed, it should start encrypting files immediately. Although the sample we tested did not encrypt files, our research has revealed that if files were encrypted, they should have the “.ohno” extension appended to their names. Unfortunately, we have no information regarding the encryption algorithms that are used by this malware. Once this information is revealed, we will update this report. When it comes to encryption, the ransomware should target photos, documents, archives, videos, downloads, and other kinds of personal data. Why? That is because you are likely to be more inclined to recover it, whereas if system files were encrypted, you could replace them. On the other hand, if your personal files are not backed up, you will not be able to recover them, and that is when the creator of OhNo Ransomware has the best chances of making you follow their demands.

If the files are encrypted successfully, OhNo Ransomware should launch a window entitled “OhNo!” to introduce you to the cyber criminals’ demands. According to the information represented via this window, the victim of the ransomware must transfer a ransom of 2 XMR to a specific account to get a decryption key. At the time of research, 2 XMR was around 209 USD, which is not that much, considering the ransom fees requested by other well-known ransomware infections. Despite this, if you pay a ransom, you should not expect to get a decryptor in return because you are dealing with cyber criminals who care about nothing but money. Unfortunately, if you pay the ransom as told, you are unlikely to get anything in return. All in all, whatever happens, you must understand that removing OhNo Ransomware is essential.
