The HELLO Ransomware is an encryption ransomware Trojan. The HELLO Ransomware uses a strong encryption method to make the victim's files inaccessible, adding the file extension '.HELLO' to each affected file. It then demands a ransom payment of 0.05 Bitcoin in exchange for the decryption key required to restore the affected files. The HELLO Ransomware and other encryption ransomware Trojans that follow a similar attack method pose a severe threat to the computer users' data. It is crucial to come up with measures to protect your files from the HELLO Ransomware and other similar attacks.

How the HELLO Ransomware Attacks a Computer

The most common way in which the victims acquire the HELLO Ransomware is through the use of spam email messages. The computer users will receive a spam email message containing an attached Microsoft Word document. These documents will use corrupted macro scripts to download and install the HELLO Ransomware as soon as the victim opens the file attachment. The HELLO Ransomware is capable of carrying out its attack on all computers using the Windows operating system. In its attack, the HELLO Ransomware will scan all the victim's drives, including external memory devices connected to the infected computer and network storage. The HELLO Ransomware will look for certain file types, encrypting them by using a combination of the RSA 2048 and AES 256 encryptions, a strong attack that makes the files inaccessible after they have been encrypted.

How the Con Artists may Profit from the HELLO Ransomware

The HELLO Ransomware will display a ransom note, which is contained in a text file dropped on the victim's computer as soon as it encrypts the victim's files. This text file, named 'HOW TO DECRYPT FILES.txt,' contains information about the attack and instructions on how to pay the ransom that the HELLO Ransomware demands from its victims. The following is the text of the HELLO Ransomware ransom note:

'Ooops, your files have been encrypted!
-What Happen to my computer?
Your important files are encrypted
Many of your documents , photos , passwords , databases and other files are no
longer accessible because they have been encrypted . Maybe you are busy looking for way to

Apart from encrypting the victim's files, the HELLO Ransomware also will ensure that the victim cannot use other methods to restore the affected files. To do this, the HELLO Ransomware will delete the Shadow Volume copies of the affected files, as well as the Windows System Restore points.

Dealing with a HELLO Ransomware Infection

If the HELLO Ransomware has encrypted your files, it is not possible to restore them without the decryption key currently. However, computer users should not pay the HELLO Ransomware ransom. The people responsible for the HELLO Ransomware attack are very unlikely to keep their word and deliver the decryption key after the payment (they are just as likely to ask for more money or ignore the victim altogether). Once the victims demonstrate that they are willing and capable of paying the HELLO Ransomware ransom, it is also very likely that they will be targeted by other threats repeatedly. Furthermore, paying the HELLO Ransomware ransom allows these people to continue creating and releasing threat variants. Instead, it is important that computer users have file backups on an external device, which can be used to recover the affected files after an attack.
