What is Jywd Ransomware

Jywd is a ransomware infection originating from the Djvu/STOP family. This family is a group of developers responsible for infecting a bunch of users with different file encryptors. Jywd is new, appeared in the end of March 2023, but has traits very similar to its precursors. Jywd Ransomware, like other variants of the STOP/Djvu Ransomware family, uses a combination of AES-256 and RSA-1024 encryption algorithms to encrypt the victim’s files. AES-256 is used to encrypt the files themselves, while RSA-1024 is used to encrypt the AES-256 key. This makes it extremely difficult to recover the encrypted files without the decryption key. The virus encrypts personal data while assigning the .jywd extension. To illustrate, a file called 1.pdf will experience a change to 1.pdf.jywd and reset its original icon after successful encryption. In order to decrypt the blocked data, victims are given instructions to follow inside a ransom note (_readme.txt).

The ransom note states files have been encrypted and will be inaccessible until victims send money to cybercriminals. It said data decryption costs $980, but can be halved down to $490 if victims contact swindlers within the first 72 hours. In addition, ransomware developers offer their victims to decrypt 1 blocked file for free. This file must not contain any valuable information to not lose the incentive of paying for full decryption. Unfortunately, decrypting files without cybercriminals is almost impossible. It can be done partially or damage file configuration if something goes wrong. The best way to capitalize on and avoid paying the ransom is to use backup copies. Many users do not have those, meaning they are desperate to remain with the encrypted data. Even so, you can still try using third-party instruments to decrypt or recover the blocked data. Note that before trying any of the recovery methods, it is necessary to get rid of the virus to prevent its further encryption activity. We elaborate on all of this in our guide below.

How Jywd Ransomware infected your computer

Ransomware infections are notoriously distributed via phishing e-mail messages. These messages are disguised as something legitimate or highly tempting to open (delivery letters, lottery winnings, free giveaways, invoices, etc.). Usually, cybercriminals try to fool users into initiating MS Office files, PDFs, Executable, and JavaScript files attached to such letters. Sometimes they add external links leading to download pages masked under official websites. Whatever it is, clicking on them will most likely result in malware infection. Although the files may look completely legitimate, they can be reconfigured and altered for storing various infections. There are many other popularly used methods to distribute ransomware as well. They are trojans, backdoors, keyloggers, web-injects, fake software updates/installers, unreliable cracking tools, and other free and pirated content that can be downloaded from third-party pages. Be careful and do not rely on their usage that much. Even if you do, make sure you do it from trusted resources and pay more attention to what you interact with on the internet.
