NOSU file virus is extremely dangerous because it corrupts important personal documents, videos, databases and other files which are essential to the victim’s work or personal life. What is even worse, the ransomware tends to install AZORULT password-stealing Trojan on the system. This malicious virus can extract all saved passwords from your browsers and possibly track your keystrokes. Therefore, a removal of such malware is essential.
The ransom note threatens to pay the ransom ASAP
The ransom note created by NOSU virus tells the victim that all important files have been encrypted. This is true – and the attackers are the only ones who have the decryption keys. To get the decryption key, the attackers suggest paying the ransom, which can cost $490 if paid within 3 days, or $980 if later. First of all, paying the cybercriminals is NEVER a recommended practice as they may never return access to your files; second, such sum of money is simply ridiculous. The note explains that the victim must write to helpmanager@firemail.cc or, if no reply within 6 hours, try writing to alternative address, helpmanager@iran.ir. The attackers are quick to respond when it comes to convinving the victim to pay up. However, they might vanish once the money is in their cryptocurrency wallet. The note also explains what is victim’s personal ID – however, there is another file on the computer containing ACTUAL ID, or IDs. Now, let us get into the ID matter further.
Free decryption possibilities
NOSU ransomware, just like the previous versions of STOP/DJVU, tend to use online OR offline keys to encrypt victims files. This, in fact, determines your chances to recover files for free. See instructions below to figure out your .nosu extension data recovery chances. In order to figure out the real victim’s IDs, one must go to C:/SystemID/ and find a file called SystemID.txt here. If you are victim of NOSU ransomware virus, you should check the IDs stored in that file and see if any of these IDs end in t1. If so, it means that some part of your data was encrypted with an offline encryption key, which means that there are chances to restore such data for free. For the IDs ending in any other character combination, free decryption is impossible. You can learn more about that here – STOP decrypter guide.
Threat Summary
STOP ransomware variants spread alongside illegal software activators
You might install NOSU file virus or other DJVU ransomware variant if you attempt to activate paid software versions illegally. For example, people often to try to obtain software licensed versions via software cracks, key generators (also known as keygens) or other activation tools such as KMSPico. You must keep in mind that such tools are cybercriminals’ go-to when it comes to malware distribution. They simply compress their illegal programs alongside such tools, or even name their viruses accordingly to deceive the unsuspecting victims. What is even worse is that people tend to ignore security software warnings NOT to open such illegal tools. Once launched, the malware infects the computer rapidly.
