What is Jack Ransomware?
Jack Ransomware is a dangerous program that will enter your system unexpectedly. One moment your computer will work like always, and then the next one you will face the ransom note popping on your screen, telling you to contact the criminals behind this infection if you want to get your files back. Needless to say, you should never pay a single cent to these criminals. Remove Jack Ransomware from your system right now, and then look for ways to restore your files. If you feel stuck, do not hesitate to address a professional technician who would let you know about other file recovery options.
Where does Jack Ransomware come from?
Jack Ransomware uses the same distribution methods as most of the other ransomware programs out there. This infection will probably reach you through spam email attachments. It might seem odd that users open spam email when most of such messages get automatically filtered into the Junk folder, right?
The problem here is that spam emails that distribute Jack Ransomware and other ransomware infections might be more sophisticated than that. They can look line online invoices or some messages from popular vendors, urging you to check out the latest information on their sales.
When Jack Ransomware comes through spam emails, you have to understand that the infection cannot reach the target unless users allow it to enter their systems. So, users often think that these installers are regular files they must check. How can you make sure that the file you are about to open is safe? Well, you can always scan it with your security tool. If you don’t have one, it is about time you invested into one. Scanning downloaded files before opening them should become your habit.
What does Jack Ransomware do?
This ransomware infection comes from the Dharma or Crysis Ransomware family. There are multiple infections out there that come from the same group, and they use similar methods to reach their victims and force them pay the ransom fees.
Therefore, we can expect Jack Ransomware to be more or less like its predecessors. We do know for sure that once this program enters the target system, it scans the entire computer, looking for the files it can encrypt. Ransomware programs seldom encrypt the entire system. They need your computer to work if they intend to receive the ransom fee; hence, Jack Ransomware leaves out the system files and targets mostly your personal library.
Just like the rest of the programs in the group, this application adds an extension to the encrypted files. The extension makes it easy to see which files were affected by the encryption, but it is usually easy to see either way because the icon changes for the affected files. Also, the extension contains the infection ID that is unique for every single system that was affected by this program. The criminals also use this ID to identify all the unique infection instances.
So, what happens when the file encryption is complete? Well, the program drops a ransom note that gives the victim a list of instructions. These instructions should help you restore your files, but we all know what Jack Ransomware wants from you – money.
