Znsm ransomware is one of the most recent versions of the notorious Djvu/STOP ransomware. Once initiated on a computer, it proceeds to encrypt files. All encrypted files will have .znsm attached to them, making it easy to identify which files have been affected. The ransomware will demand that you pay $980 for a decryptor in order to recover your files after they have been encrypted. Unless you have a backup of your encrypted files, file recovery may not be possible. This is why this ransomware is so dangerous. Even paying the ransom comes with its own risks and is generally not recommended.
Znsm ransomware is virtually identical to every other version that is released by these cyber criminals. The versions can be differentiated by the extensions they add to encrypted files. This one adds .znsm, hence why it is referred to as Znsm ransomware. All personal files, such as photos, videos, and documents will be targeted. Once encrypted, these files will have .znsm attached to them. image.jp, for example, would become image.jpg.znsm if encrypted. Unfortunately, you will not be able to open any files with this extension.
To distract victims from what is happening while the ransomware is encrypting their files, it will display a fake Windows update window. The _readme.txt ransom note that is dropped in all folders that contain encrypted files has instructions on how to get the decryptor from the cyber criminals. Despite being quite generic, the note has all the relevant information. Although the note does mention that victims who get in touch with the malicious actors within the first 72 hours will receive a 50% discount, the decryptor generally costs $980.
It’s difficult to say whether the discount part is true or not but paying the ransom, in general, is not a good idea because there are many risks. Most significantly, there are no guarantees that you will in fact get a decryptor if you pay. Keep in mind that you’re dealing with cyber criminals, and even if you pay them, they likely will not feel obligated to assist you. In the past, many victims have paid for decryptors but never received them. Therefore, while the decision is ultimately yours, we strongly advise against giving in to the demands. Additionally, your money would be used to fund further criminal activities. Ransomware will continue to be a problem as long as victims continue to pay the ransom.
File recovery may be difficult if you don’t have any backups of your files. There is no free Znsm ransomware decryptor available right now, and it’s uncertain when or even if it would be released. The fact that this ransomware encrypts files using online keys makes it challenging for malware researchers to create a decryptor. Victims of this ransomware all have unique keys, without which a decryptor would not work. It’s not impossible that the keys will eventually be released because it has happened before but at this moment, a free Znsm ransomware is unlikely. If it does get released, it would be posted on NoMoreRansom.
In the event that you do have a backup, you can begin file recovery as soon as you delete Znsm ransomware from your computer. Because Znsm ransomware is a sophisticated malware infection, we don’t advise you to try to manually remove it. You can do more harm than good. Use a good anti-virus program to delete Znsm ransomware. Once it’s fully removed, you can access your backup to start recovering files. It’s worth mentioning that if the ransomware is still present on your computer when you connect to your backup, your backed-up files would become encrypted as well.
Ransomware distribution methods
Malware infection is considerably more likely to occur when users have poor online habits. Using torrents to pirate copyrighted content, opening unsolicited email attachments, and clicking on dubious ads when visiting high-risk websites are all examples of poor online habits. You can prevent malware infections in the future if you take the time to develop better habits.
The most popular method used by malicious actors to spread ransomware is email. Cybercriminals only need to buy leaked email addresses from hacker forums and send malicious emails to those addresses, making it a very low-effort method. Users’ computers get infected and their data is encrypted when they open the attached malicious files.
Fortunately, you should be able to spot malicious emails with ease if you know what to look for. Malicious emails, for example, frequently contain grammar and spelling mistakes despite sanders claiming to be from legitimate companies. Try to recall the last time you got an email from a reputable company that had obvious grammatical and spelling mistakes.
Another sign is words like Member, Customer, User, etc., being used to address you when the sender should know your name. Keep in mind that names are automatically included in emails when the sender company has your name on file. But because malicious actors rarely have access to personal information, they use generic words.
It’s also important to note that certain malicious emails can be considerably more sophisticated, which is why it’s recommended to always scan unsolicited email attachments using anti-malware software or a service like VirusTotal.
Malware is also frequently distributed using torrents. It’s no secret that torrent websites lack adequate moderation, making it simple for malicious actors to post torrents with malware. Malware is frequently found in torrents for well-known films, TV series, video games, software, etc. Therefore, using torrents to pirate is risky for your computer. It’s also essentially content theft.

You need to use anti-malware software to remove Znsm ransomware from your computer because it’s a sophisticated infection. You risk unintentionally causing more damage if you try to do it manually.
