The latest version of the RotorCrypt Ransomware was released in June 2018 with!@#$%__PANAMA1@TUTAMAIL.com__%$#@.mail’ extension, !@#$_____ISKANDER@TUTAMAIL.COM_____$#@!.RAR extension and the!@!@!@_contact firstname.lastname@example.org___!@!@.psd .mail extension as the new additions.
RotorCrypt Ransomware – Threat Behavior
The RotorCrypt Ransomware infiltrates the system through spam email campaigns where the user receives mails which contain infectious attachments. These attachments are from popular file type extensions such as .doc, .txt, .zip, .pdf, .jpeg etc. that require ‘editing to be enabled’ in the software to open these file. Once the user enables editing the file then sends a command to hacker’s servers which then download the virus payload in the user’s system. These files may also be executable files which will download the virus payload on execution.
The main executable file of the RotorCrypt Ransomware makes changes to the important folders in the victim’s system. The folders that may undergo the changes are %AppData%, %Temp% and %Local%. The ransomware Virus uses windows command prompt and may delete the Shadow Volume copies and may disable system recovery.
The RotorCrypt Ransomware uses the RSA data encryption to encrypt the user’s files. The infected files are then changed to the complicated and long suffixes that contain the contact email to pay the ransom.
The user’s photos, videos, documents and other files are then encrypted with a .mail extension variant that the cyber criminals have appended for the files. The three latest .mail extensions are !@#$%__PANAMA1@TUTAMAIL.com__%$#@.mail’ extension, !@#$_____ISKANDER@TUTAMAIL.COM_____$#@!.RAR extension and the !@!@!@_contact email@example.com___!@!@.psd which were discovered in June 2018.
These emails are shown in the ransom note which is generated as a .txt file on the desktop. The user is asked to contact the developers by using these email addresses namely PANAMA1@TUTAMAIL.com, ISKANDER@TUTAMAIL.COM and firstname.lastname@example.org. The ransom note asks for payment to be made in bitcoin so as to avoid tracking and detection by investigative agencies. The ransom demand may range from 1-3 bitcoins in the newer versions while the older version demanded 7 bitcoins that amounted to more than 60,000$.
The RotorCrypt Ransomware is known to make changes to the .mail extension of the files encrypted on a users system with new .mail extensions to keep the hactivists guessing about the next attack. This does not change the threat behavior as it asks for ransom from the user for the decryption key.
The user should never crumble under these threats. Paying money to these cyber criminals should never be an option. The user should look for ways to remove the RotorCrypt Ransomware from the system.
