What is Anubi Ransomware? And how does it implement its attack?
Anubi ransomware is a new ransomware-type of infection discovered by a malware security researcher named S!Ri. It appends the [[email protected]].anubi to its targeted files. When it infects a computer, Anubi will set an autorun first in the Windows Registry so it can automatically start once a user logs in. It then begins to scan the entire drive of the computer looking for files to encrypt. During the encryption, it appends the .[email_address].anubi extension to all the compromised files. Although it does not encrypt files on unmapped network shares, it does encrypt the files on the mapped network shares.
After it has finished the encryption process, it drops a ransom note in a text file named _READ_ME_.txt throughout the computer
