What is Naampa?
Naampa is a ransomware virus that encrypts all users’ personal files. To do this, it is used RSA-2048 asymmetric algorithm when the decryption key is created immediately during the encryption. The procedure takes a little time so the user may not even notice anything suspicious. As a result, each affected file will be appended with .crptd extension, for example, myfamily.jpg is changed to myfamily.jpg.crptd. At the end of encryption, Naampa Ransomware leaves ransom note in Russian in form of JPEG file (“!—-README—-!.jpg”). This virus is primarily aimed at Russian-speaking users, which does not prevent it from spreading around the world.
This is what Naampa ransom note contains (translation into English):
Your files are encrypted using the RSA-2048 algorithm.
If you want to return them, send one of the encrypted files and key.res file to e-mail:
If you do not receive a reply within 24 hours or the letter is returned with an error, then download from the site www.torproject.com browser TOR and with his help go to the site
xxxx://n3r2kuzhw2h7x6j5.onion – there will be specified a valid mailbox.
Attempts to repair files yourself can irrevocably ruin them!
