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

The Brotherhood ransomware is a new file-encrypting virus discovered this week on July 3, 2018. This new malware strain is created based on the open-source platform, HiddenTear. Based on the analysis done by security experts, it seems that this crypto-malware is still under development at the time of writing. This new addition to the HiddenTear ransomware group includes a hardcoded encryption key which could mean that it might be intended to run in offline mode by default.

Cybercriminals are known to take advantage of open security platforms in order to test if their malicious program can evade the detection of antivirus programs. Luckily, this also allows malware researchers to keep up with the new trends in the crypto-malware environment and assist victims in recovering their encrypted files.

As mentioned, The Brotherhood ransomware is designed to run in offline mode. And once it carries out its attack, it will search for its targeted files on the infected PC. According to security experts, it only encrypts files located in the Documents folder so it may encrypt files with the following extensions:

.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp

After it finds the files it’s been looking for, The Brotherhood ransomware appends the .ransomcrypt extension to each one of them and then changes the desktop wallpaper of the infected device with a JPG file named “RansomNote.jpg” which contains the following message:

“Your files have been encrypted. To decrypt your file, please transfer 100 BTC

Otherwise, you will lose your file today at 16:30:00hrs

HACKED THE BROTHERHOOD”

Threat actors demand users 100 BTC from their victims. However, paying such a huge amount is definitely not recommended as crooks tend to ignore victims once they get the demanded ransom. The best way to deal with crypto-malware like The Brotherhood ransomware is by eliminating them from the system right away before they can do more damage to important data.

How is the malicious payload of The Brotherhood ransomware disseminated?

The malicious payload of The Brotherhood ransomware may be disseminated using malicious spam email campaigns. Meaning to say, threat actors behind this crypto-virus attach an obfuscated file in emails and send them to potential victims. Once this obfuscated file is opened, it will automatically launch The Brotherhood ransomware into the system. Thus, you need to take extra precautions in opening emails.
