.Arrow Ransomware - A dangerous Ransomware from Dharma family

Earlier in March, HTRI's research team saw what had all the earmarks of being a new version of the Crysis/Dharma Ransomware uploaded to their test website.

Our research team found a sample to affirm that it was without a doubt another Crysis variation.

This new form will add the “.arrow” extension to the encrypted or locked files.

It isn't known precisely how this version is being moved, however, in the past Dharma was commonly spread by hacking into Remote Desktop Services and installing the ransomware manually or through malicious email attachments.

Once after .Arrow ransomware is tricked into a system, it will check a PC for data files and encrypt them.

While encoding a record, it will attach an extension in the arrangement of .id-[id].[email].arrow.

For instance, a file named test.jpg would be encrypted and renamed to test.jpg.(id-here).[vauvau@cock.li].arrow.

Also, it was noticed that this ransomware will encrypt mapped network drives and unmapped system shares.

So, it is necessary to ensure your system's network is secured with an end-goal that the individuals who really require access have permission.

After encrypting the files, it would leave a ransom note.
