removal by Olivia Morelli - - | Type: Ransomware

Qewe ransomware is the ransomware that cannot get decrypted unless the offline keys get used in the encryption process

Qewe ransomware virusQewe ransomware is one of many Djvu family versions that count more than 220 separate variants already. This is the threat that runs in the background and causes all the changes before it displays any visible symptoms. The first and the most important function that this malware has is file locking that allows the creators of the virus to make a profit directly from victims. Users notice data that gets marked using .qewe extension nad becomes inoperable. This is the indication of a successful encryption procedure that ransomware runs as soon as it lands on the computer. Since Djvu ransomware and STOP virus family, in general, are known creators of dangerous cryptocurrency-extortion based threats, we can immediately tell that paying is not an option, in this case. 

Even though versions that came out before August of 2019 were easily decryptable, Qewe ransomware virus is no longer based on the same coding and encryption functions. Online keys were used less often, so many people got their files restored with the help of researchers and tools designed to find victims of the same version. Ransomware now connects to the server each time the encryption process runs on the targeted machine, so victims get unique victim IDs that are no longer matching with any other person or users. Emsisoft still offers the procedure of recovering files, but their Djvu decryption is based on offline IDs only, so when your ID in the ransom note file ends in t1, you can have the option of decryption. However, other victims cannot repair the damage since keys are formed separately for each of them.[1]

Qewe ransomware is the version of the virus that was decryptable before. Cybercriminals evolve and make their products more persistent, so these malware creators updated their coding procedures and started to use more advanced methods and rely on online IDs. Offline keys can change with versions only, these keys were more useful for researchers and malware-fighting tools. Online IDs allow making each victim unique and different from other users affected by the same version of the ransomware.

There is no solution for your files expert recovery from backups because these victim IDs needed for decryption tools are stored on malicious actors' servers. Unless the database of the malware creators get leaked or Qewe ransomware developers get caught by law enforcement.

Ransomware scripts can run in the background and affect security features, other programs and run the encryption again if you do not remove all parts of the infection.

However, often the processes that are set to run in the background cannot be easily stopped or found. You may need to rely on a few AV tools to double-check or enter the Safe More before you run the anti-malware in the first place.  Qewe ransomwareQewe ransomware is the virus that marks data using its own file extension as an indicator for affected files.

Malware evolves as technologies change. Cybercriminals also rely on more modern ways to spread their products around. This is the reason why ransomware is more stealthily and dangerous than ever before. malicious actors were more focused on email campaigns before and obtained payments from people who opened a malicious attachment from emails.

Now there are more hacked or malicious sites with triggers that allow downloads of malicious scripts and start infections like this. In addition, pirated sites, and torrent services become one more technique that allows spreading malware payload via files attached to software packages. In most cases, online games, cheats, software cracks, and license numbers when downloaded triggers the infection.

The best solution for avoidance of these infections can be paying attention to sources and choosing the official sites, not torrent or other sharing services. Illegal downloads and licensed versions are never a good idea. Keep anti-malware tools running more often, so these infections get indicated at the start of an infiltration.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Qewe and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
