How to remove Dazx Ransomware and decrypt .dazx files

What is Dazx Ransomware

Dazx Ransomware is a version of the STOP/Djvu ransomware family. It is a type of malware that encrypts the files on a victim’s computer and demands a ransom payment in exchange for the decryption key. When the Dazx Ransomware infects a computer, it will encrypt the victim’s files using a strong encryption algorithm, making them inaccessible to the victim. Malware uses a symmetric encryption algorithm to encrypt the victim’s files. Specifically, it uses the Salsa20 stream cipher to encrypt the data. The encryption key is generated randomly for each victim, and it is stored on the attacker’s server. The encrypted files will have a new extension added to their filenames, such as .dazx. The Dazx Ransomware also creates a ransom note file called _readme.txt in every folder that contains encrypted files. This file contains instructions on how to pay the ransom in order to receive the decryption key. The ransom note also warns the victim against attempting to decrypt the files using third-party software, as this can result in permanent data loss.

The Dazx Ransomware demands a ransom payment of either $490 or $980, depending on how quickly the victim contacts the attackers. If the victim contacts the attackers within 72 hours of infection, they are offered a discount and asked to pay $490. If they contact the attackers after 72 hours, the ransom amount increases to $980. It’s important to note that paying the ransom does not guarantee that the attackers will provide the decryption key or that the victim’s files will be recovered. Victims of ransomware attacks are advised to not pay the ransom and seek assistance from a reputable cybersecurity professional or organization.

When the ransomware infects a computer, it first scans the local drives for targeted file types, such as documents, images, videos, and archives. It then encrypts these files one by one, replacing their original data with the encrypted data. The encrypted files are given a new extension, such as “.dazx”, to indicate that they have been encrypted. To decrypt the files, the victim needs the unique decryption key that corresponds to their infection. The attacker provides this key only after the victim pays the ransom. If the victim pays the ransom, the attacker sends them the decryption key, and the victim can then use this key to decrypt their files. It’s important to note that attempting to decrypt the files without the correct decryption key is extremely difficult, if not impossible. This is because the encryption key used by the ransomware is unique for each victim, and it is not possible to recover the key from the encrypted data without the attacker’s assistance, unless there was a loss of internet connection during encryption. There are also some optional methods, that may help you succeed in restoring lost data, that we describe on this page.

How Dazx Ransomware infected your computer

Dazx Ransomware, like many other types of malware, can infiltrate computers in a variety of ways. Here are some common methods:

• Phishing emails: The attackers may send emails that look like they come from a legitimate source, such as a well-known company or organization. These emails often contain a malicious attachment or a link to a website that hosts the malware. Once the victim clicks on the attachment or link, the malware is downloaded and executed on their computer.
• Malicious downloads: The attackers may distribute the malware through software downloads from untrusted or illegitimate sources, such as peer-to-peer file sharing networks or cracked software sites. When the victim downloads and installs the software, the malware is also installed on their computer.
• Exploits: The attackers may exploit vulnerabilities in software or operating systems to gain access to the victim’s computer. These vulnerabilities may be present in outdated or unpatched software, or in software that has not been properly configured.
• Malvertising: The attackers may use malicious advertising to distribute the malware. They may create fake ads that look like legitimate ones and place them on popular websites. When the victim clicks on the ad, they are redirected to a website that downloads the malware onto their computer.

7. How to protect from threats like Dazx Ransomware

Virus modifies “hosts” file to block Windows updates, downloading antivirus programs, and visiting sites related to security news or offering security solutions. Dazx 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. Dazx 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 Dazx Ransomware are: Emsisoft Anti-Malware and Malwarebytes Anti-Malware.
