Sapp ransomware belongs to the notorious Djvu/STOP malware family. The ransomware will encrypt all personal files, essentially taking them hostage. Because of this, it’s considered to be a very serious infection. For users who have backups of their files, file recovery will not be an issue as long as Sapp ransomware is deleted from the computer first. However, users with no backups may not be able to recover their files. The ransomware operators will try to sell the decryptors to victims for $980 but even paying comes with certain risks.


Sapp ransomware note


All ransomware versions from the Djvu/STOP family, including Sapp ransomware, are fundamentally the same. The malicious actors operating this ransomware have released hundreds of these infections but they can be differentiated by the extensions they add to encrypted files. This ransomware adds .sapp. For example, an encrypted text.txt file would become text.txt.sapp. Files with this extension will be unopenable until you use a specific decryptor on them. The files that are targeted the most are images, photos, videos, and documents because users are most willing to pay for them.

A _readme.txt ransom note with instructions on how to buy a decryptor will be dropped in folders that have encrypted files. According to the note, the decryptor costs $980 but there’s a 50% discount for victims who contact the cybercriminals within the first 72 hours. It’s debatable whether the claims of a discount are true, but there are several risks associated with paying. The most important thing to mention is that you are dealing with cyber criminals and that there are no guarantees that you will actually get the decryptor. It’s unlikely that the cybercriminals behind this ransomware will feel any kind of obligation to help you, even if you pay. Many users paid the ransoms in the past but did not receive their decryptors. The decision to pay or not is yours to make but you need to be aware of the risks that come with it.

Sapp ransomware files

File recovery shouldn’t be a problem for those who have backups. However, users must first remove Sapp ransomware from their computers. If the backup is accessed while the ransomware is still active, the backed-up files would also be encrypted. Files would be irreversibly lost if that happened. The safest and simplest way to delete Sapp ransomware is to use anti-malware software, and that is what we recommend doing. This will guarantee that your computer sustains no more harm and that the infection is completely eliminated.

Unfortunately, your options are very limited if you don’t have a backup. Waiting for a free Sapp ransomware decryptor to be released is one of the few options. Because this ransomware uses online keys to encrypt files, there is no free decryptor available at the moment. When ransomware uses online keys to encrypt files, the keys are unique to each victim. Without those keys, a decryptor is not very likely. It’s not impossible that the keys will eventually be released, so back up your encrypted files and occasionally check for a free Sapp ransomware decryptor.

How does ransomware spread

One of the most popular methods used by cybercriminals to spread malware is email attachments. Cybercriminals only need to buy email addresses from hacker forums, write a somewhat convincing email, and attach a malicious file to it, making it a relatively low-effort distribution method. Users’ computers become infected as soon as they open the malicious file. As long as those attached files remain unopened, the emails are not dangerous. Fortunately for users, malicious emails are frequently relatively simple to identify. The emails frequently contain several grammar and spelling mistakes. Senders often pretend to be from legitimate businesses, so the mistakes look very obvious and out of place. Grammar and spelling mistakes would make an email from a business whose services you use look very unprofessional.

Another red flag is when a sender who ought to know your name addresses you using words like “User,” “Member,” or “Customer”. You likely already noticed that emails from senders whose services you use always address you by name. It makes the email seem more personal.

Lastly, it’s worth mentioning that some malicious emails may be much more sophisticated. Thus, it’s recommended to scan all email attachments with anti-virus software or VirusTotal before opening them.

Additionally, torrents are also used to spread malware. Most torrent users are already aware of this but torrent sites are often quite poorly moderated, which allows malicious actors to upload torrents with malware in them. If users do not know how to recognize malicious torrents, they can easily end up with malware. Most commonly, torrents for entertainment content (e.g. movies, TV series, video games) contain malware. Using torrents to pirate copyrighted content is also essentially theft.

How to remove Sapp ransomware

Anti-malware software should be used to remove Sapp ransomware from your computer because it’s a rather sophisticated infection. If you try to do it manually yourself, you could end up causing serious damage to your computer unless you know exactly what to do. It’s much easier, and safer to use anti-virus software. As soon as the anti-virus program has completely removed Sapp ransomware, you can connect to your backup and start recovering your files safely.

If you do not have a backup, your only option may be to wait for a free decryptor to be released. Unfortunately, it’s not certain when that would happen, or even if. However, if it does get released, it would be posted on NoMoreRansom.
