Isza ransomware or .isza virus is a type of malware that encrypts files. It’s part of the Djvu/STOP ransomware family and is one of the most recently released versions. Your data will be encrypted by the ransomware, and it will demand a ransom to unlock them. This makes ransomware an extremely dangerous infection. Besides the different extensions they add to encrypted files, ransomware versions from this family are mostly identical. This one is known as Isza ransomware because it adds .isza to encrypted files. Users who have backups should have no trouble restoring their files. However, users without backup currently have very little chance of file recovery.


Isza ransomware note


Like other infections of this type, Isza ransomware will target all of your personal files. That includes photos, videos, images, documents, etc. The extension that is added to encrypted files will make it possible for you to recognize which files have been affected. This one adds .isza, and an encrypted image.jpg file would become image.jpg.isza. The only way to open files with this extension is to first decrypt them. But getting the decryptor won’t be so simple.

Once the files have been encrypted, the ransomware will drop a _readme.txt ransom note in the folders containing encrypted files. The note does explain how files can be recovered despite being very generic. Unfortunately, getting the decryptor requires paying the cybercriminals behind this ransomware for a decryptor. The decryptor currently costs $980. However, there is allegedly a 50% discount available to victims who get in touch with cyber criminals within the first 72 hours. Whether that is genuinely the case or not is debatable, but paying the ransom is very risky. What you need to know is that even after paying, you are not guaranteed to receive a decryptor. Since you’re dealing with cyber criminals, they probably won’t feel obligated to assist you. Despite paying the ransom in the past, many users did not receive their decryptors. Whether to pay is your decision but you need to be aware of all the risks.

Isza ransomware files

Use anti-malware software to remove Isza ransomware from your computer. Do not try to manually delete Isza ransomware because you risk causing more harm. You can start the file recovery process if you have a backup after the anti-malware removes the ransomware. Keep in mind that your backed-up files would be encrypted as well if the ransomware was still active on your computer when you accessed your backup.

The only option you have if you don’t have a backup is to wait for a free Isza ransomware decryptor to become available. There isn’t one available right now, but one might be released in the future. Although Emsisoft offers a free Djvu/STOP decryptor, it is unlikely to work on Isza ransomware. The Djvu family’s more recent ransomware variants encrypt files using online keys, which means the keys are specific to each user. And the decryptor provided by Emsisoft can only assist users whose keys it has. But even if it is unlikely to work, it is still worth a shot. It’s also possible that a free Isza ransomware decryptor will be released eventually. Back up your encrypted files and wait for a free decryptor to become available if you are out of options.

Ransomware distribution methods

Distributors of ransomware use a variety of methods to distribute malicious infections. In general, users who have poor online habits are considerably more likely to come across malware infections. Users are more likely to infect their computers with malware, for instance, if they open unsolicited email attachments without double-checking them beforehand. Malicious actors prefer email attachments for distributing malware because that requires very little effort. They buy email addresses from various hacker forums, write semi-convincing emails, and attach malicious files to them. Users initiate the infection when they open the attachments. But fortunately, the emails are typically fairly obvious.

In order to persuade users to open the attachments, malicious senders often pose as representatives of well-known, trustworthy companies. The emails typically state that the attachments are important files that need to be urgently reviewed. For example, the email may claim that the attached file is a receipt. However, whether done on purpose or not, the emails frequently contain embarrassing amounts of grammar and spelling mistakes. Additionally, malicious senders typically use words like “User”, “Member”, “Customer”, etc. when addressing users. Companies whose services users use will always address them by name because doing otherwise appears unprofessional.

Malicious emails are typically quite evident. However, emails may be considerably more sophisticated if malicious actors have access to specific personal information. It is always recommended to run a VirusTotal or anti-virus software scan of any unsolicited email attachments before opening them.

Additionally, downloading malware from torrents is fairly common. Because torrent websites are frequently poorly regulated, malicious actors can post torrents that contain malware. Torrents for popular media including movies, TV shows, video games, and software frequently contain malware. Therefore, using torrents to illegally download copyrighted content amounts to stealing and is risky for the computer and its data.

How to delete Isza ransomware

Anti-malware software should be used to delete Isza ransomware because it’s a complicated infection. We advise against attempting to do it manually since you risk further harming your computer. Furthermore, you might not completely remove Isza ransomware unless you are very experienced, which could subsequently enable it to recover. Additionally, if you attempted to access your backup while ransomware was still active, your backup files would also be encrypted. And if that happened, your files might be permanently lost.

Once you fully remove Isza ransomware, you can open your backup to begin the file recovery process. Back up your encrypted files if you don’t have a backup, and then wait for a free Isza ransomware decryptor to become available. Even though it might take some time, it’s possible that it will be released eventually.
