How to remove Jaqw Ransomware and decrypt .jaqw files

What is Jaqw Ransomware

Jaqw Ransomware is a highly malicious crypto locker type of virus that encrypts the infected user’s files rendering them unusable. It is another variant of the STOP/DJVU malware group. It is worth noting that Djvu ransomware is frequently disseminated alongside information stealers like RedLine or Vidar by malicious actors. Jaqw functions by encrypting files and altering their filenames through the addition of the .jaqw extension. It encrypts all important file types, including databases, documents, photos, movies, and music. Jaqw Virus uses the Salsa20 encryption algorithm. This ransomware ciphers a wide selection of file types using a strong encryption algorithm. The ransom note generated by Jaqw is _readme.txt, which includes a message detailing the ransom demands. The ransom note issued by the attackers contains two email addresses.

The best way to deal with Jaqw Ransomware is to remove it from the infected computer and restore the files from a backup. Deciphering files that have been locked by Jaqw ransomware presents a complex challenge due to the sophisticated encryption algorithms employed by this type of malicious software. There are no decryption tools available for Jaqw Ransomware yet. However, users can try searching for decryption keys on Emsisoft or No More Ransom. It is worth noting that many of the new variants of this file locker virus are impossible to decrypt independently and eventually even most experts are still having difficulties in finding a recovery for these encrypted files that is why most people are resorting to the only option which is to pay the ransom. Paying the ransom is not recommended as it does not guarantee the recovery of the files.

How Jaqw Ransomware infected your computer

Ransomware spreads in several different ways, but the most common infection methods include social engineering (phishing), malvertising, fileless attacks, remote desk protocol, MSPs and RMMs, drive-by downloads, pirated software, network propagation, and malware obfuscation. The main method of infection by Jaqw is to encrypt files and demand ransom money from victims who want to decrypt the data. It is usually spread through spam emails and email attachments.

Virus modifies “hosts” file to block Windows updates, downloading antivirus programs, and visiting sites related to security news or offering security solutions. Jaqw Ransomware comes along with AZORult trojan, which was initially created to steal logins and passwords. The process of infection also looks like installing Windows updates, the malware shows a fake window, that mimics the update process.

It uses rdpclip.exe to replace a legal Windows file and to launch an attack on a computer network. After encrypting the files, the encrypter is deleted using the delself.bat command file. Jaqw Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. Can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged, and infected installers. The virus assigns a certain ID to the victims, which is used to name those files and supposedly to send a decryption key. Great tools to protect against Jaqw Ransomware are: Emsisoft Anti-Malware and Malwarebytes Anti-Malware.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Jaqw Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.
