A new ransomware has been released that not only encrypts your files, but also deletes them if you take too long to make the ransom payment of $150 USD.
The Jigsaw Ransomware, named after the iconic character that appears in the ransom note, will delete files every hour and each time the infection starts until you pay the ransom.
At this time is currently unknown how this ransomware is distributed.
This is the first time that we have seen these types of threats actually being carried out by a ransomware infection. The good news is that a method has been discovered that allows victims to decrypt their files for free.
Jigsaw Ransomware is serious about its threats...
It is not the first time that we have seen ransomware threaten to delete files, but this is the first time that one has actually carried out its threats.
The Jigsaw Ransomware deletes files every 60 minutes and when the program is restarted.
Every hour, the Jigsaw Ransomware will delete a file on your computer and increment a counter.
Over time this counter will cause more than one file to be deleted every hour.
More destructive, though, is the amount of files that are deleted every time the ransomware starts.
After the initial infection, when the ransomware it restarted, whether that be from a reboot or terminating the process, Jigsaw will delete a thousand, yes a thousand, files from the victim's computer.
This process is very destructive and obviously being used to pressure the victim into paying the ransom.
How to decrypt and remove the Jigsaw Ransomware
Thankfully, through the analysis of MalwareHunterTeam, DemonSlay335, and Lawrence Abrams it was discovered that it is possible to decrypt this ransomware for free.
Using this information, Demonslay335 has released a decryptor that can decrypt files encrypted by the Jigsaw Ransomware.
To decrypt your files, the first thing that you should do is terminate the firefox.exe and drpbx.exe processes in Task Manager to prevent any further files from being deleted.
You should then run MSConfig and disable the startup entry called firefox.exe that points to the %UserProfile%\AppData\Roaming\Frfx\firefox.exe executable.
Once you have terminated the ransomware and disabled its startup, let's proceed with decrypting the files.
The first step is to download and extract the Jigsaw Decryptor from the following URL:
https://download.bleepingcomputer.com/demonslay335/JigSawDecrypter.zip
Then double-click on the JigSawDecrypter.exe file to launch the program.
When the program launches you will be greeted with a screen similar to the one below.
To decrypt your files simply select the directory and click on the Decrypt My Files button.
If you wish to decrypt the whole drive, then you can select the C: drive itself.
It is advised that you do not put a checkmark in the Delete Encrypted Files option until you have confirmed that the tool can properly decrypt your files.
When it has finished decrypting your files, the screen will appear as below.
Now that your files are decrypted, I suggest that you run an antivirus or anti-malware program to scan your computer for infections.
