What is Boom ransomware? And how does it carry out its attack?

Boom ransomware is a malicious file-encrypting virus that was first discovered at the end of December 2018. This new crypto-malware uses the AES 256 encryption algorithm in encrypting important files. It starts to carry out its attack by placing its payload dropper in the system. This payload dropper will run and connect the system to a remote server. From this remote server, Boom ransomware will download its other malicious components and place them on system folders.

After that, it will make entries as well as modify existing ones in the Windows Registry. This allows Boom ransomware to automatically carry out its attack on every system boot, making its attack persistent. It then uses its malicious components to employ a data harvesting module and a stealth protection module in order to gather information from the system and use it to bypass firewalls, security programs, debug environments, and antivirus programs installed in the computer. Once it completes modifying system settings, it begins encrypting files in the computer using the AES 256 cipher. After the encryption, it adds the .Boom suffix to every encrypted file and opens a text file named “HOW TO DECRYPT FILES.txt” containing the following message:

“Oooooops All your files have been encrypted
And to encode the files, enter the password
to get a password
Search in Facebook
My name = Mohamed Naser Ahmed
my ID = 100027091457754
see you soon”
In addition, Boom ransomware also opens a program window that contains another ransom note stating:
“Welcome You in Boom Ransomeware
All your Files have Been Encrypted
To Decrypt the
Encryption enter PIN
We will extract your password on your Desktop
Enter the pin to extract the password
Do not try to turn off the computer
more than 10 times
Because you will lose files forever”

In the program window, there is a “Get PIN” button that when clicked, will redirect you to a broken Facebook page. If you are one of the victims of this nasty ransomware threat, you must not click any of the links or buttons that this ransomware displays. The best way to deal with it is to wipe it out of your computer and restore encrypted files using alternative methods instead of contacting the cybercriminals behind it.
