Ransom note by BlackMist ransomware

BlackMist is a ransomware-type cyber infection that is still in development. Crypto-malware is designed to encrypt files using AES[1] cryptography, append .BlackMist file extension and deliver a ransom note. Cyber criminals demand to pay $100 in Bitcoins for data recovery.

On the affected computer, BlackMist virus is loaded from BlackMist.exe file. The ransomware targets only own directory: C:\Users\Owner. However, it can encrypt the majority of different types of files stored there, including audio, video, documents, images, backups, and similar data.

The BlackMist ransomware is also expected to delete Shadow Volume Copies which are crucial in data recovery. However, in this way crooks can easily get money from desperate computer users who need their files back right now. However, paying the ransom may not be the effective data recovery method.

The ransom note has two tabs – “Info” and “Dashboard.” In the first tab, cyber criminals note that users have 48 hours to transfer the money. The timer at the bottom of the ransom-demanding window shows estimated time. However, after 24 hours, the virus claims to delete a random portion of the files. The deletion of records continues each following hour until all files will be gone for good after two days time.

It’s still unknown if BlackMist can do this harmful activity or not. However, it’s pretty clear that crooks want to make people terrified. They also tell that closing the program or turning off the computer will end up of deletion of personal files. Though, it’s not likely to happen.

It’s important to scan the computer with antivirus program in order to remove BlackMist. After the attack, malware also makes modifications to the system. It might alter Windows Registry and install malicious entries as well. Thus, you will no longer be able to use your computer safely and normally until you get rid of the virus.

For BlackMist removal, we recommend choosing Reimage. However, you can choose your preferred tool as well. We want to warn that crypto-virus may prevent you from installing or scanning the system with security software. Thus, you may need to reboot the computer to Safe Mode first.

Ransomware distribution methods and tips to avoid the attack

The file-encrypting virus might infiltrate the system via:

  • malicious spam emails and their attachments;
  • malware-laden ads;
  • bogus or illegal software downloads;
  • fake updates;
  • unprotected RDP connections;
  • exploit kits.

As you can see, attackers might reach you using various ways. Thus, in order to protect your PC and data, you have to:[2]

  • be careful with email attachments and open them only if you are 100% certain that it’s a legit file;
  • do not click on suspicious or “too-good-to-be-true” ads;
  • install programs from the reliable sources and trusted developers;
  • do not agree to install updates from pop-ups;
  • keep your programs updated;
  • install all available system updates;
  • protect your PC with professional antivirus.

Security experts from Poland[3] claim that it’s easy to get tricked by cyber criminals even if you are aware of these security tips. Thus, you should backup up your files and updated them regularly in order to survive ransomware attack without any damage.
