Isal ransomware is one of the more recent Djvu/STOP ransomware variants, a type of malware that encrypts files. As usual, this ransomware targets personal files, and once they’re encrypted, you will lose access to them. All ransomware infections have one fundamental goal: to encrypt files and demand payment from victims in exchange for a decryptor.
Djvu/STOP ransomware versions are mostly identical to one another but you can tell them apart by the extensions they add to encrypted files. This one adds .isal. If you don’t have a backup of the encrypted files, you might not be able to recover the files once they have been encrypted.
The Djvu/STOP ransomware family has hundreds of ransomware variants, albeit they are largely interchangeable and only differ in the extensions they add to encrypted files. Because it appends .isal to the files it encrypts, this ransomware is known as Isal ransomware. This ransomware targets all personal files, including photos, videos, documents, etc. As mentioned above, encrypted files will have .isal attached to them. For example, image.jpg would become image.jpg.isal if encrypted. Files with that extension will not be openable until they have been decrypted. However, a special decryptor is required in order to decrypt the files. Unfortunately, the cybercriminals operating this ransomware are the only ones with a decryptor. Additionally, they won’t offer it to you for free because they profit from extorting their victims. They will attempt to convince you to pay for it instead.
When the ransomware has finished encrypting your data, it will drop a _readme.txt ransom note. The note explains how to get the decryptor. Unfortunately, the decryptor costs $980. The note does suggest a 50% discount for users who contact the cybercriminals within the first 72 hours, however, it is dubious whether this discount would actually be given. In general, it is not advised to give in to the cybercriminals’ demands and pay the ransom. Even if you paid, there are no guarantees that you would receive the decryptor. You are dealing with cyber criminals, and since they have no legal obligation to do otherwise, they could just take your money without sending you the decryptor. In fact, despite paying the ransom in the past, many users did not get their decryptors. Additionally, your money would be used to fund future criminal activities.
As soon as you delete Isal ransomware from your computer, you can connect to your backup if you have it. To fully delete Isal ransomware from your computer, we strongly advise using anti-malware software; otherwise, you risk damaging your computer even more.
Without a backup, there is no certainty that files can be recovered. The only thing you can do is wait until a free Isal ransomware decryptor is released. Because this ransomware uses online keys to encrypt files, a free decryptor is difficult to develop for malware researchers. Online keys mean that each user has a unique key. A free Isal ransomware decryptor is unlikely unless those keys are released by the hackers themselves or by law enforcement. A free Djvu/STOP ransomware decryptor is available from Emsisoft, however, it only works with Djvu versions that encrypt files using offline keys and only if Emsisoft has the key. Although there currently isn’t a free Isal ransomware decryptor available, one might be released in the future. So make a backup of your encrypted files, and occasionally check for a free decryptor on NoMoreRansom.
How did ransomware enter your computer?
Typically, ransomware that targets random users spreads through email attachments, torrents, advertisements on dubious websites, etc. This explains why users who engage in risky behavior online are significantly more likely to expose their computers to malware. Make the effort to develop better browsing habits and familiarize yourself with malware distribution techniques if you wish to avoid malware in the future.
If you use torrents, you are probably already aware of the fact that torrents frequently contain malware. Because torrent sites are not well moderated, malicious actors can post torrents containing malware. Users who download those torrents end up installing malicious software on their computers. Malware is frequently found in torrents for well-known films, TV shows, video games, and software. Users are urged to refrain from downloading copyrighted content using torrents or from pirating in general because doing so is illegal and risky for their computers and data.
Emails with malicious attachments are likely to be sent to users whose email addresses have been leaked. Leaked email addresses are sold on various hacker forums for other malicious actors to purchase and use for their malware campaigns.
Fortunately, malicious email campaigns are frequently extremely obvious. Usually, malicious senders pose as representatives of legitimate companies whose services users use. By implying that the files are important documents or receipts that must be read, they coerce users into opening the attachments. However, the emails frequently contain grammar and spelling mistakes, which suggest that they could be malicious.
You won’t often see grammar/spelling mistakes, or at least they won’t be as obvious, in legitimate emails because they come across as unprofessional. Furthermore, when a legitimate sender would have used your name to address you, malicious senders instead use generic terms like “User”, “Member”, “Customer”, etc.
It’s also important to note that malicious campaigns can also be very sophisticated. Therefore, before opening any unsolicited email attachments, it is advised to scan them with anti-malware software or VirusTotal.
How to remove Isal ransomware
We advise against attempting to manually remove Isal ransomware because it is a very sophisticated malware infection. You might unintentionally harm your computer if you don’t know exactly what you’re doing. Furthermore, the ransomware might be able to recover if you miss some of its components. Your backed-up files would also get encrypted if you were in the middle of retrieving your files from a backup when the ransomware recovered.
To remove the Isal ransomware from your computer, use a good anti-malware program. You can safely connect to your backup to begin restoring files once the ransomware has been completely removed.
