What is Wwza virus/ransomware?

Wwza ransomware, also known as STOP (Djvu) ransomware, is a malicious software that encrypts files on the victim’s computer and demands payment in exchange for a key and a decryptor that can restore access to the files. The virus spreads by disguising itself as legitimate software and can infect a computer through various means, including downloading programs from torrent websites, running hacked games or freeware, and installing key generators for Windows or Office software.

Once the virus infects a computer, it creates a directory in the Windows system directory, copies itself to that directory, and changes some OS settings. It then attempts to connect to a command server to receive an online key for file encryption. If it cannot connect, it uses a fixed offline key instead. The virus renames each encrypted file by adding the “.Wwza” extension to the original file name. The only files that are not encrypted are those with the extensions .dll, .lnk, .bat, ini, .sys, and files named “_readme.txt.”

The authors of Wwza ransomware leave a message in the “_readme.txt” file in each directory that contains at least one encrypted file. The message informs victims that all their files are encrypted with strong encryption and that the only way to recover them is to purchase a decrypt tool and a unique key. The ransom demand starts at $980, and victims are given a 50% discount if they pay within 72 hours. The authors offer to decrypt one file for free to prove that the files can be decrypted.

Fortunately, security researchers have developed tools to decrypt files encrypted with an offline key, such as the Wwza File Decypt Tool from Emsisoft. However, files encrypted with an online key remain inaccessible unless the attackers themselves release the key. Victims of Wwza ransomware are advised not to pay the ransom, as there is no guarantee that the attackers will provide a working decryptor. Instead, they should use reputable anti-malware software to remove the virus from their computer and attempt to recover their files using the available decryption tools.

In conclusion, Wwza ransomware is a dangerous malware that can cause significant damage to a victim’s files and data. It is essential to take measures to protect your computer, such as avoiding downloading suspicious software and installing reputable anti-malware software. If you have been infected with Wwza ransomware, it is crucial to act quickly. To learn more about Wwza ransomware and how to protect yourself from it, please read our detailed guide.
