Brief Introduction of RSA-4096 Ransomware

RSA-4096 is deemed as a new version of a well-known ransomeware, which is currently using an encryption algorithm even stronger than RSA-2048. Similar to other ransomware, RSA-4096 is often spread via spam email attachments, corrupted websites, malicious hyperlinks. Besides, it may also spread via free software downloaded from unreliable websites. That’t why so many users have no idea how and when their computers get infected.

Once infected, it may take over your web browsers and give a ransom message in your folders, claiming that files were encrypted via RSA-4096. You can see parts of  message below:

“What happened to your files ?
All of your files were protected by a strong encryption with RSA-4096.
More information about the encryption keys using RSA-4096 can be found here: http://en.wikipedia.org/wiki/RSA_(cryptosystem)
How did this happen ?
!!! Specially for your PC was generated personal RSA-4096 KEY, both public and private.
!!! ALL YOUR FILES were encrypted with the public key, which has been transferred to your computer via the Internet.
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.
What do I do ?
So, there are two ways you can choose: wait for a miracle and get your price doubled, or start obtaining BTC NOW, and restore your data easy way….”

As you can see, RSA-4096 encrypts your files to lock your PC and display a message to inform you. However, the developer of RSA-4096 ransomware just attempt to trick you into paying the certain ransom to unlock your files. You should note that it uses unique bitcoin payment addresses for each victim instead of hard coded links. Unfortunately, the files encrypted by the RSA-4096 ransomware might not be recovered. So you should not follow its steps to pay the ransom since there is no guarantee. If you do not remove the ransomware as soon as possible, it may bring more other problems to your PC such as poor PC performance, vulnerable system, disabled programs, and additional malware/viruses, etc. Therefore, it is urgent that RSA-4096 ransomware should be removed from your computer without any hesitation.
