Jasa ransomware is malware that targets personal files and encrypts them. It’s part of the Djvu/STOP ransomware family and is one of the hundreds of currently active versions. The ransomware versions can be recognized by the extensions added to encrypted files. This one adds .jasa. Unfortunately, if the ransomware manages to encrypt your files, your backup would be the only certain way to recover them. If you do have a backup, you can access it as soon as you remove Jasa ransomware from your computer.
Ransomware infections are immediately obvious because you will not be able to open your files. They will also have a .jasa extension attached to them. For example, a text.txt file would become text.txt.jasa if encrypted. All personal files, including photos, videos, and documents will be targeted. These are the files users are most willing to pay for so they are the usual targets.
Once ransomware is done with file encryption, you will find a _readme.txt ransom note in all folders that have encrypted files. The note is identical to the ones dropped by other ransomware versions from this family. Unfortunately, the decryptor is currently sold for $980. The note does mention a 50% discount for users who make contact within the first 72 hours but we do not recommend paying, whatever the amount. You are dealing with cyber criminals, and there is no guarantee that you will get the decryptor. Many users did not receive their decryptors despite paying in the past.
If your files have been backed up prior to infection, you can access your backup and start recovering files. However, you need to remove Jasa ransomware from your computer beforehand. You need to use a reliable anti-malware program to do this because ransomware is a complex infection that requires professional solutions. Do not access your backup while the ransomware is present because the backed-up files will become encrypted as well. They would then be permanently lost.
For users who do not have backups, the only option is to wait for a free Jasa ransomware decryptor to be released. It’s not uncommon for free decryptors to be released by malware researchers, but it’s not always possible to make one. There is a free Djvu/STOP ransomware decryptor by Emsisoft currently available but it’s unlikely to work on files encrypted by Jasa ransomware or any newer Djvu versions. If a Jasa ransomware decryptor does get released, it will be posted on NoMoreRansom.
How did Jasa ransomware enter your computer?
Ransomware is distributed in many ways, and infection is usually the result of users’ bad habits. One of the best ways to prevent ransomware infections is to familiarize yourself with the most common distribution methods and develop better habits.
One of the most common ways your computer could get infected is via email attachments. Malicious actors launch email campaigns that have malware attached to them, and it’s users whose email addresses have been leaked that are the common targets. If the malicious attachments are opened, users’ computers become infected. Fortunately, generic emails that contain malware are quite obvious so as long as you are careful, you should have no trouble identifying them.
Emails that have malware attached to them are often deliberately made to appear like they’re sent by legitimate companies. For example, such an email could be made to look like a parcel delivery notification. However, what gives these emails away is grammar and spelling mistakes. That is one of the most obvious signs of a malicious email because mistakes are not common in emails sent by legitimate companies, certainly not in automatic emails.
You can also judge whether an email is legitimate by the way you are addressed. If an email is from a company whose services you use, you will almost always be addressed by name. You should be suspicious when a sender who should know your name uses generic words like User, Member, or Customer when addressing you.
You should also always scan unsolicited email attachments with anti-virus software or VirusTotal before you open them. This would ensure that you do not open malicious files.
Lastly, it should be mentioned that torrents are also commonly used when distributing malware. It’s common knowledge that torrent sites are quite poorly moderated, which allows malicious actors to upload entertainment content torrents with malware in them. Malware is most often found in torrents for popular movies, TV series, and video games. Using torrents to download copyrighted content is content theft anyway, so we discourage you from pirating.
Jasa ransomware removal
These types of infections are very sophisticated, which is why you should not try to remove Jasa ransomware manually. If you try to do it yourself, you could end up causing additional damage to your device by accident. To avoid this, we strongly recommend using anti-malware software to delete Jasa ransomware.
Unfortunately, just because you remove Jasa ransomware from your computer does not mean your files will be recovered. That is only possible if you have a backup or if you get a Jasa ransomware decryptor.
You can safely access your backup to start recovering files as soon as the ransomware is no longer present. If you were to access your backup with ransomware still on your computer, your backed-up files would become encrypted as well.
