Threat Database Ransomware Noos Ransomware

Noos Ransomware

It would seem that nowadays, every cyber crook is trying their luck with ransomware threats. Some build nasty file-locking Trojans from the ground up, but most prefer to save themselves the effort and simply borrow readily available code from already established ransomware threats.

Propagation and Encryption

One of the most recent data-encrypting Trojans is the NoosRansomware. Once the Noos Ransomware was dissected, it became clear that this is yet another variant of the notorious STOP Ransomware. It is likely that the most common ransomware propagation methods may be at play when it comes to Noos Ransomware's infection vectors – bogus application updates, fraudulent pirated variants of popular software and mass spam email campaigns. A brief scan will be performed as soon as the Noos Ransomware manages to compromise a system. The scan serves the purpose of locating all the data of interest. As the next stage, the ransomware threat will begin encrypting all the data. When the Noos Ransomware locks a file, it also will make sure to change its filename. This file-locking Trojan appends a '.noos' extension to the newly encrypted files. For example, an audio file that was initially named 'Hugo-B.mp3' will be renamed to 'Hugo-B.mp3.noos' when the Noos Ransomware completes its encryption process.

The Ransom Note

When the encryption process is done, the Noos Ransomware will drop a ransom note on the desktop of the user. The note is called '_readme.txt' and states:

The ransom fee demanded is $980, but the attackers claim that all users that make contact them within 72 hours of the Noos Ransomware attack will get a 50% discount meaning they will have to pay $490. The authors of the Noos Ransomware offer the victim to send them one file, which they will decrypt for free as proof that they have a working decryption key. The creators of this ransomware threat have provided two email addresses where you can get in touch with them – ‘' and ‘'

It is better to keep distance from any cyber crooks. These are not people you can trust and are very likely to never deliver on their promises even if you pay the ransom fee. Instead, you should look into obtaining a reputable anti-virus solution that will wipe out the Noos Ransomware from your computer and make sure you do not find yourself in a similar situation in the future.
