LQQW Virus Ransomware ✔️ How to decrypt .lqqw files?

The Lqqw virus is a STOP/DJVU family of ransomware-type infections. This virus encrypts your files (video, photos, documents) that can be tracked by a specific “.lqqw” extension. It uses a strong encryption method, which makes it impossible to calculate the key in any way.

Lqqw uses a unique key for each victim, with one exception:

  • If Lqqw cannot establish a connection to its command and control server (C&C Server) before starting the encryption process, it uses the offline key. This key is the same for all victims, making it possible to decrypt files encrypted during a ransomware attack.

I have gathered a complete collection of all possible solutions, tips, and practices in neutralizing the Lqqw virus and decrypting files. In some cases, it is easy to recover your files. And sometimes it is just impossible.

There are several universal methods for recovering encrypted .lqqw files, which will be demonstrated below. It is vital to read the entire instruction manual carefully and make sure to understand it all. Do not skip any steps. Each of these steps is very important and must be completed by you.

Lqqw virus?

☝️ Lqqw can be correctly identify as a STOP/DJVU ransomware-type virus.

Lqqw

🤔 Lqqw virus is ransomware that originates from the DJVU/STOP family. Its primary purpose is to encrypt files that are important for you. After that ransomware virus asks its victims for a ransom fee ($490 – $980) in BitCoin.

The Lqqw ransomware is a kind of malware that encrypted your documents and then forces you to pay to restore them. Djvu/STOP ransomware family was first revealed and discovered by virus analyst Michael Gillespie.

Lqqw virus is basically similar to other DJVU ransomware like: Iwan, Orkf, Hoop. This virus encrypt all common file types and adds its own “.lqqw” extension into all files. For instance, the file “1.jpg”, will be amended into “1.jpg.lqqw“. As soon as the encryption is successfully accomplished, virus creates a specific text file “_readme.txt” and puts it into all folders that contain the modified files.

The image below gives a clear vision of how the files with the “.lqqw” extension look like:

This message asking payment is for restore files via decryption key:

_readme.txt (STOP/DJVU Ransomware)

_readme.txt (STOP/DJVU Ransomware) – The scary alert demanding from users to pay the ransom to decrypt the encoded data contains these frustrating warnings

The cryptography algorithm used by DJVU/STOP ransomware is AES-256. So, if your documents got encrypted with an online decryption key, which is unique. The sad reality is that it is impossible to decrypt the files without the unique key.

In case if Lqqw worked in online mode, you can’t gain access to the AES-256 key. It is stored on a remote server owned by the criminals who promote the Lqqw ransomware.

For receiving decryption key the payment should be $980. To obtain the payment details, the victims are encouraged by the message to contact the frauds by email ([email protected]).

The message by the ransomware states the following information:

Do not pay for Lqqw!

Please, try to use the available backups, or Decrypter tool

_readme.txt file also indicates that the computer owners must contact the Lqqw representatives during 72 hours starting from the moment the files were encrypted. On the condition of getting in touch within 72 hours, users will be granted a 50% rebate. Thus the ransom amount will be minimized down to $490). Yet, stay away from paying the ransom!

I strongly recommend that you do not contact these crooks and do not pay. The one of the most real working solution to recover the lost data – just using the available backups, or use Decrypter tool.

The peculiarity of all such viruses apply a similar set of actions for generating the unique decryption key to recover the ciphered data.

Thus, unless the ransomware is still under the stage of development or possesses some hard-to-track flaws, manually recovering the ciphered data is a thing you can’t perform. The only solution to prevent losing your valuable data is to make backups of your crucial files regularly.

Note that even if you maintain such backups regularly, they ought to be put into a specific location without loitering, not being connected to your main workstation.

For instance, the backup may be kept on the USB flash drive or some alternative external hard drive storage. Optionally, you may refer to the help of online (cloud) information storage.

Needless to mention, when you maintain your backup data on your common device, it may be similarly ciphered as well as other data.

For this reason, locating the backup on your main PC is surely not a wise idea.

How I was infected?

Ransomware has a various methods to built into your system. But it doesn’t really matter what concrete method had place in your case.

Lqqw ransomware attack

Lqqw ransomware attack following a successful phishing attempt.

Nevertheless, these are the common leaks through which it may be injected into your PC:
  • hidden installation along with other apps, especially the utilities that work as freeware or shareware;
  • dubious link in spam emails leading to the virus installer
  • online free hosting resources;
  • using illegal peer-to-peer (P2P) resources for downloading pirated software.

There were cases when the Lqqw virus was disguised as some legitimate tool, for example, in the messages demanding to initiate some unwanted software or browser updates. This is typically the way how some online frauds aim to force you into installing the Lqqw ransomware manually, by actually making you directly participate in this process.

Surely, the bogus update alert will not indicate that you are actually going to inject the virus. This installation will be concealed under some alert mentioning that allegedly you should update Adobe Flash Player or some other dubious program whatsoever.

Of course, the cracked apps represent the damage too. Using P2P is both illegal and may result in the injection of serious malware, including the Lqqw ransomware.

To sum up, what can you do to avoid the injection of the Lqqw ransomware into your device? Even though there is no 100% guarantee to prevent your PC from getting damaged, there are certain tips I want to give you to prevent the Lqqw penetration. You must be cautious while installing free software today.

Make sure you always read what the installers offer in addition to the main free program. Stay away from opening dubious email attachments. Do not open files from the unknown addressees. Of course, your current security program must always be updated.

The malware does not speak openly about itself. It will not be mentioned in the list of your available programs. However, it will be masked under some malicious process running regularly in the background, starting from when you launch your computer.
