Carj ransomware encrypts files and adds the .carj extension to them. Your files have been encrypted by ransomware if they suddenly have this extension and you are unable to open them. Carj ransomware is a very dangerous computer infection that belongs to the infamous Djvu/STOP ransomware family. Without first using a decryptor on them, you will not be able to open any of the encrypted files. But obtaining the decryptor will not be easy. Those who are running this ransomware are the only ones who presently have access to it, and they won’t be kind enough to give it to you for free. But paying for a decryptor is not recommended because you would not necessarily get it.


Carj ransomware note


Carj ransomware is one of the more recent Djvu/STOP versions. Usually, cybercriminals release a few versions every week, with hundreds of them already released. Though they are largely identical, the versions can be differentiated by the extensions they add to encrypted files. This ransomware adds .carj, hence why it’s known as Carj ransomware. All of your personal files will have this extension, including photos, videos, and documents. For example, document.txt would become document.txt.carj if encrypted. Without the correct decryptor, you will not be able to open files with this extension.

The decryptor will be offered to you by the cybercriminals operating this ransomware. The process of buying it is explained in the _readme.txt ransom note that can be found in all folders that have encrypted files. Unfortunately, cybercriminals demand $980 for the decryptor. It is mentioned in the note that those who get in touch within the first 72 hours will receive a 50% discount, though it is not certain whether this is truly the case.

Generally, we advise against paying the ransom. The decision is yours but there are some risks you should be aware of. The most crucial point to stress is that, even after paying, there are no guarantees that you will be sent the decryptor. What’s to stop cyber criminals from simply taking the money and not sending the decryptor? Because they are the ones who encrypted your files in the first place, they are unlikely to feel compelled to help victims, even those who pay. Additionally, victims paying the ransom is one of the reasons ransomware has become such a successful business. Not to mention that the paid money goes toward future criminal activities.

Users who regularly back up important files shouldn’t have a problem with file recovery. But before accessing the backup, you need to remove Carj from the computer completely. Ransomware would encrypt your backed-up files if you connected to your backup while it was still active. Therefore, we strongly advise using anti-virus software to delete Carj ransomware. Avoid attempting manual Carj ransomware removal because you might end up doing more harm by accident.

File recovery is significantly more challenging when users have no backups. It’s occasionally possible for malware researchers and security experts to release free decryptors to assist victims, but it’s difficult in this situation. Carj ransomware and the majority of other versions from this family use online encryption keys, which means all victims have unique keys. The chances of creating a functional decryptor are slim without those keys. Although Emsisoft has released a free Djvu/STOP decryptor , it is doubtful that it will be compatible with the Carj ransomware. But it’s still worth a shot.

How did Carj ransomware enter your computer?

Malicious actors frequently spread their malware through malicious emails, also referred to as malspam. It’s a very low-effort method of malware distribution. Threat actors purchase the email addresses of victims from various hacker sites and use them for their malicious campaigns in the hopes that recipients will open the malicious files they have attached. Malware is initiated as soon as the malicious file is opened.

Fortunately, you can prevent a lot of malware if you learn to identify malicious emails. The most obvious sign is grammar/spelling mistakes. They’re especially obvious when the sender claims to be from a legitimate company, emailing with important business. You will never see such obvious mistakes in legitimate emails because they look very unprofessional. Furthermore, malicious emails usually address users with words like User, Member, Customer, etc., instead of using their names. Emails from senders whose attachments you’d need to open will always address you by name. Companies use this tactic to make emails seem more personal. However, because malicious actors target a large number of users with the same malicious campaign, they use generic words to address users.

It’s a good idea to scan all unsolicited email attachments with anti-virus software or VirusTotal  before opening them, just to be sure they’re safe. Some malicious campaigns can be highly sophisticated, particularly if they target someone specific.

Using torrents to pirate copyrighted content is discouraged because it’s not only content theft but also dangerous for the computer/data. Torrent sites are often poorly moderated, which allows malicious actors to upload torrents with malware in them. Malware is especially common in torrents for popular entertainment content, including torrents for movies, TV series, and video games.

There are plenty of other ways ransomware and other malware can be distributed. Infections can also be acquired by downloading files from dubious websites, clicking on advertisements, visiting risky websites, etc. You can prevent a lot of malware if you take the time to develop good browsing habits.

How to delete Carj ransomware

It’s always advised to use anti-virus software when removing malware. To remove Carj ransomware, be sure to use a good anti-virus program and allow it to take care of everything. Before you access your backup and start file recovery, you need to make sure the ransomware is completely gone from your computer. Otherwise, your backed-up files would become encrypted as well.

After the ransomware has been removed, you can safely connect to your backup. If you don’t have a backup, back up encrypted files while you wait for a free Carj ransomware decryptor.  NoMoreRansom is one of the safest places to get decryptors from.
