What is KyMERA ransomware? And how does it carry out its attack?

KyMERA ransomware, also known as NotAHero ransomware, is a file-encrypting threat designed to encode important files in an infected computer. This crypto-malware is not to be underestimated as it is not your typical ransomware infection. Once it manages to infiltrate a computer, it will drop its malicious payload which initiates its attack. This malicious payload will connect the infected system to a remote server controlled by the attackers. From there, it downloads a couple of files that help it in carrying out its attack.
KyMERA ransomware could also modify and make some entries in the Registry. Usually, ransomware threats modify the RunOnce keys in order to run on every system boot. Some of the malicious files downloaded by KyMERA ransomware are also used to keep it invisible from any programs that could interfere with its attack. Once all these changes are successfully carried out, it begins the encryption process. During the encryption, it employs the AES encryption algorithm in encrypting files. All the encrypted files will then get the “” extension, making the files inaccessible to users. Following data encryption, it opens a window screen labeled, “KyMERA RansOm By Gian” which contains the following message:
“KyMERA RansOm By Gian
All your files have been encrypted!
All your documents (databases, texts, images, videos, music, etc. were encrypted. The encryption was done using a secret key, that is now on our servers. To decrypt your files you will need to buy the secret key from us. We are the only in the world who can provide this for you.
