After completing the encryption process, it creates YOUR_FILES.txt that explains users about the attack and instructs them that they need to pay a ransom to decrypt the files.

The amount of the ransom is not provided of the ransom note, although it asks users to contact the threat developers using [email protected] email address. They will provide the private key that help in restoring of the files. The note further states not to wait for a long since the key is available for only 7 days and if the contact is not made within this limited period, the last hope for  the files recovery becomes deleted. Here is the complete text on the file:

Short messages convince recipients into clicking such file attachments. If done, the users are asked to enable macros command. One more click leads them into downloading/installing malware. Thus, it becomes necessary to be careful when receiving any emails. At least check senders’ addresses. In case of any doubt, avoid opening them.

Untrustworthy downloading channels include free file hosting sites, p2p networks and third party downloaders/installers offer rogue applications. The fake software updaters/cracking tools infect computers by supposedly updating/activating software. Use official sources for software download/install and update and avoid using any cracking tools for activating any paid software.

They can target system process and inject malicious entries on them to make the system start misbehave.  Keeping them longer inside PC can cause other files encryption that are left unencrypted as well. They can enable shell command and delete Shadow Volume Copy or other backup that could be an option for data recovery.

Further, the viruses can target stealing stored personal data and injecting other malicious malware.
