What is Ann ransomware? And how does it implement its attack?

Ann ransomware is a new ransomware threat designed just like a typical crypto-malware. At the time of writing, the threat actors behind this crypto-malware are still unknown though it was determined that it does not belong to any ransomware group. Just like a typical ransomware threat, once it implements its attack, it drops its malicious payload in the system and establishes a connection to a remote server controlled by its creators.

After its infiltration, it creates and downloads several malicious files and place them into system folders. It then employs a data gathering module used to obtain information about the user and the infected PC. After that, the harvested data, along with the malicious components are then used for stealth protection that allows the crypto-malware to carry out its attack without any interruptions by avoiding detection from security programs. Once all these modifications are completed, it starts to execute its main attack which is to encrypt important files in the computer. According to security experts, ANN ransomware uses both the AES 128 and RSA 2048 encryption algorithms in locking files. After the encryption, it appends the .ANN file extension to every encrypted file making them inaccessible. Following data encryption, it makes its presence known by opening its ransom note which contains the following message:
