NAPOLI Virus 🔐 (.NAPOLI Files) — How to Remove?

The Napoli virus belongs under the Chaos ransomware family. Harmful software of such sort encrypts all user’s data on the PC (photos, documents, excel tables, music, videos, etc) and adds its extra extension to every file, creating the read_it.txt files in every directory which contains the encrypted files.

Napoli virus: what is known so far?

☝️ Napoli is a Chaos family ransomware-type malicious agent.

Napoli adds its extra .napoli extension to every file’s name. For instance, an image named “photo.jpg” will be renamed to “photo.jpg.napoli”. Just like the Excel table named “table.xlsx” will become “table.xlsx.napoli”, and so on.

In every folder that contains the encrypted files, a read_it.txt text file will be created. It is a ransom money note. Therein you can find information about the ways of paying the ransom and some other remarks. The ransom note most probably contains a description of how to purchase the decryption tool from the ransomware developers. That is it.

How did my machine catch Napoli ransomware?

There are plenty of possible ways of ransomware injection.

Nowadays, there are three most exploited ways for hackers to have the Napoli virus settled in your digital environment. These are email spam, Trojan infiltration and peer-to-peer file transfer.

  • If you access your inbox and see emails that look like familiar notifications from utility services providers, delivery agencies like FedEx, Internet providers, and whatnot, but whose sender is strange to you, beware of opening those letters. They are most likely to have a malware file enclosed in them. Therefore, it is even riskier to open any attachments that come with letters like these.
  • Another option for ransom hunters is a Trojan file scheme. A Trojan is an object that gets into your computer disguised as something different. Imagine, you download an installer for some program you need or an update for some program. However, what is unpacked reveals itself a harmful program that encrypts your data. Since the installation wizard can have any title and any icon, you have to make sure that you can trust the resource of the stuff you’re downloading. The best way is to use the software companies’ official websites.
  • As for the peer file transfer protocols like torrents or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. So you’d better be using trustworthy resources. Also, it is reasonable to scan the folder containing the downloaded objects with the anti-malware utility as soon as the downloading is complete.

How do I get rid of ransomware?

It is crucial to note that besides encrypting your files, the Napoli virus will probably install Vidar Stealer on your computer to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned program can derive your logins and passwords from your browser’s auto-filling cardfile.

How do I avert ransomware infiltration?

Napoli ransomware has no superpower, neither does any similar malware.

You can armour your system from ransomware infiltration taking several easy steps:

  • Never open any emails from unknown mailers with strange addresses, or with content that has nothing to do with something you are waiting for (can you win in a money prize draw without even taking part in it?). In case the email subject is likely something you are waiting for, check all elements of the suspicious letter with caution. A hoax email will always have mistakes.
  • Never use cracked or untrusted programs. Trojan viruses are often distributed as a part of cracked software, most likely under the guise of “patch” to prevent the license check. But untrusted programs are very hard to tell from trustworthy ones, as trojans may also have the functionality you seek. You can try searching for information on this software product on the anti-malware forums, but the optimal way is not to use such software.

Frequently Asked Questions

🤔 How can I open “.napoli” files?Are the “.napoli” files accessible?

Unfortunately, no. You need to decipher the “.napoli” files first. Then you will be able to open them.

🤔 I really need to decrypt those “.napoli” files ASAP. How can I do that?

It’s good if you have fаr-sightedly saved copies of these important files elsewhere. Otherwise, you might try to employ System Restore. The only question is whether you have saved any Restore Points that would be helpful now. The rest of the methods require patience.

🤔 What should I do if the Napoli virus has blocked my PC and I can’t get the activation key.

🤔 And what should I do now?

Many of the encoded files might still be at your disposal

  • If you exchanged your important files through email, you could still download them from your online mail server.
  • You may have shared images or videos with your friends or relatives. Simply ask them to post those pictures back to you.
  • If you have initially downloaded any of your files from the Internet, you can try doing it again.
  • Your messengers, social media pages, and cloud disks might have all those files too.
  • It might be that you still have the needed files on your old computer, a notebook, phone, memory stick, etc.

USEFUL TIP: You can use file recovery utilities2 to get your lost data back since ransomware blocks the copies of your files, removing the original ones. In the tutorial below, you can learn how to use PhotoRec for such a restoration, but remember: you won’t be able to do it before you kill the virus with an anti-malware program.
