The main attack strategies used by the malware authors of Nuow virus have been identified to be the following:
- E-mail messages sent to users by the names of trustworthy brands and services. What’s typical for these e-mails is the presence of file attachments of common types (PDF, documents, archives, etc.) or URLs. Such elements could possibly download and run ransomware code on each computer device.
- Shady sites that promote various supposedly useful apps or cracked versions of legitimate applications. Installation packages downloaded from such sites may deliver the ransomware infection directly to your computer system.

The Nuow virus will also drop its _readme.txt ransom note file.
What Are .nuow Files?
All .nuow virus files are locked by the use the AES encryption algorithm. Additional ciphers may have been added to the buil-it encoding module of this variant of STOP. All personal files that are detected to be among the targets of this ransomware will be transformed and renamed with the extension .nuow. All of the following types of files may be encoded:
- Videos (.mp4, .avi, etc.).
- Audio (.mp3, .wav, etc.).
- Picture file kinds (.jpg, .png, .etc).

Unfortunately, if your files have been encrypted by Nuow ransomware, it most probably means that the battle is lost. The chances to get your files restored on your own or with the help of a company/a professional that advertises decryption capabilities are nearly non-existent. What most such companies and professionals do is buy a decryption tool from the ransomware operators, and add a markup to the ransom amount upon charging you for their decryption services. In other words, trusting anyone, other than an officially released decrypter, with the decryption of your files is utterly pointless. We will update this article once we have more information on possible decryption, even though the chances are quite slim. What you should do for now is remove the ransomware from your system, so that it doesn’t reinfect you and it doesn’t spread further.
