A ransom virus, dubbed RedAnts has been reported to cause encryption via the AES (Advanced Encryption Standard) encryption. The virus encrypts the files on the compromised computers after which adds the .Horas-Bah file extension to them and a file named READ_ME.txt which aims to display ransom demands to pay the sum of 0.5 BTC to the ones behind this ransomware infection in order to get the files back. However, paying is strongly inadvisable. Instead, we recommend reading the following article carefully.
|Short Description||The malware encrypts users files using a strong encryption algorithm, called Rijndael, making direct decryption possible only via a unique decryption key available to the cyber-criminals.|

.Horas-Bah – How Does It Infect
For this ransomware virus to cause an infection, malicious spam campaigns via e-mail are undertaken. Those campaigns are very variable and may contain different convincing messages which aim to get the victim to open the malicious e-mail attachment.
Other methods of infection include the usage of fake web installers of different programs as well as other fake patches of programs or game cracks uploaded on torrent hosting websites.

The Encryption Process of RedAnts Ransomware
For the encryption of the files, RedAnts ransomware uses the AES encryption algorithm, also known as Rijndael. What the virus does is it replaces bytes of the files with symbols from the encryption cipher, but does not encrypt the file entirely, just enough so that the files are no longer openable.
The virus may also delete the shadow volume copies to make sure the user is unable to recover the encrypted files by using different data recovery programs. This is achievable by inserting the vssadmin command as an administrator in Windows Command Prompt.
After the encryption has completed, the files cannot be opened by any previously recognizable program in Windows and the OS begins looking for software to open them with:
