Ta Nulltica Ransomware (Hur man tar bort Instruktion)

Nulltica what is called Ransomware, under the umbrella term Malware. Cyber criminals use Ransomware to lock your computer and ask for money to decrypt the encrypted files using the Nulltica Ransomware.

After infection with the Ransomware virusNullticathere is a new browser window opened, redirecting to a web page How To Send Bitcoins.

 

If Ransomware has been recently spreading thru the internet and their cybercriminals are still busy with their illegal practices, it can help to pay the Ransom to key to decrypt the files. Emellertid, we do NOT recommend to pay the Ransom, ever. Chances are that the Ransomware virus is spreading but theownersare already stopped their illegal practices or do not respond in any way. If you have paid, you receive no key, and no files are decrypted.

Also by paying the Ransom, you contribute to the illegal practices of the Ransomware creators.

In the case of the Nulltica Ransomware they want you to pay 50 USD by bitcoin.

How does the Nulltica Ransomware infect computers?

Cybercriminals often use a deceptive method called Social Engineering to spread their Ransomware. They send out many e-mails to random or compromised e-mail accounts with an attachment. This e-mail may look as there are from your bank, delivery services (as for instance UPS) or word-document coming from a close contact that got infected and sent out an automatic e-mail without their notice.

It’s also known that Ransomware is not only spreading thru the internet by e-mail. Cyber criminals use compromised websites or advertisement networks and add known or unknown exploits that automatically infected your computer as it’s not up-to-date or missing important updates.

As this Ransomware is downloaded or put on your computer automatically it might look like a zip file or a PDF file, but it’s an executable. Cybercriminals change the icon to deceive users into thinking it’s a legitimate file.

After opening thislegitimatefile, the Ransomware Nulltica uses an encryption algorithm to encrypt files found on the computer, this often takes a while as it first starts scanning the computer for known file extensions to change them to .lock.

By encrypting files they become unreadable and they cannot be opened without thekeyor the decrypting tool that can restore the files to their original file format. That’s what Cybercriminals offer for the money.

Cyber criminals exploit the emotions such as fear, urgency, curiosity, the sympathy of the human. The computer technique can stop a lot, but if the human does decide to open an unknown file, then the Ransomware virus or any malware, i allmänhet, can infect and compromise the computer system.

Can I recover my files after a Nulltica Ransomware infection?

So if you have put back a restore point in Windows before the Nulltica Ransomware infection you can try this method. Again, cyber criminals know this method and it will probably not work.

But we want to help you so we have included this method in this instruction.

To restore individual files or folders that are encrypted by the ransomware, PC users can try the Previous Version of Microsoft Windows feature. Once again; This method is effective if the System Restore feature was activated on the infected computer and a successful recovery point is put back in place.

Know that some versions of the Nulltica Ransomware remove the volume shadow copies (Shadow Copies, or Volume Snapshot Service) deleted and this method will not work. Continue.

To restore a file, right klick on the file or folder, go to Properties and select the Previous Version tab. If the selected file or folder has a restore point, select a date and click the Restore knappen.

7. Shadow Explorer, Recuva, EaseUS Data Recovery, R-Studio software to recover files

Should the instruction we have written were not successful for Windows and recover your files, then there is a chance one these software suites might recover your files for you.

Shadow Explorer

Most Ransomware will detect and delete Shadow Copies, but sometimes they fail or they are not intended to remove Shadow Copies (fake Ransomware for example. Yes it exists..) however, Shadow Explorer can recover these file(s) for you.

The following video explains how to recover files with Shadow Explorer

Recuva from Piriform

Because Ransomware first makes a copy of a file, then encrypts the copy and then deletes the original. There is a chance that there may be retrieved a copy of the file(s)s using software Recuva, from Piriform.

See the instruction video how this is done. No guarantees, worth trying.

EASEUS Data Recovery Wizard Free

Just like Recuva, EASEUS Data Recovery is an option to retrieve deleted files.

See the following instruction video on how to use the EASEUS Data Recovery Wizard Free software.

R-Studio

Again an alternative to retrieving files. R-Studio also allows a free trial to see if it works for you to retrieve an important file.

Here’s an instructional video from R-Studio, how to use it to recover files.
