Newly released ransomware variant, naming itself Karma ransomware has been reported to wreak havoc onto the computers of multiple users. This specific type of malware is very dangerous, primarily because it uses a strong encryption to encode the files of users after which append the .karma suffix on them and make them no longer able to be opened by the user until a hefty ransom fee is being paid.
More Information About Karma Ransowmare
First discovered by a malware researcher on Twitter, the virus encrypts the files and adds a .karma file extension to their names. When the virus has executed it’s malicious files, it immediately begins to modify the registry subkeys and create new values with data in them. The targeted keys are the following:
In those keys, the ransomware set’s to run the files it has created, which are it’s malicious executable that encrypts the files and the two ransom notes it drops on Windows desktop, that are named accordingly “# DECRYPT MY FILES #.html” and “# DECRYPT MY FILES #.txt”
After the files are dropped, the ransomware also changes the wallpaper on the infected computer. The wallpaper is very specific and has the following message to the victim:
Is the content of the files that you looked for not readable?

What is encryption?
Encryption is a reversible modification of information for security reasons but providing full access to it for authorized users.
To become an authorized user and keep the modification absolutely reversible (in other words to have a possibility to decrypt your files) you should have an individual private key.
But not only it.
It is required also to have the special decryption software (in your case “karma Decryptor” software) for safe and complete decryption of all your files and data.
Everything is clear for me but what should I do?

One method to become a victim of this nasty ransomware virus is to download free setups of programs like your favorite media player or torrent engine. But the difference in Karma’s case is that those setups may be combined with malicious files that may cause the infections this way. One malware researcher has discovered a fake Windows performance booster program, called Windows-Tuneup v1.0.0 that caused the infection in one particular case.

From there, malware researchers strongly advise against directly paying the ransom fee of Karma and instead to focus on alternate ways to restore the files, comme:
- Data Recovery programs.
- Any Windows shadow copies.
- Using a network sniffer to restore the encrypted files by locating the decryption key the Karma ransomware sends to the cyber-criminals.
