Vlff ransomware comes from the family of non-decryptable threats

Vlff file virus is an infection that is used by cryptocurrency extortion criminals. The threat acts as the reason for criminals to demand money from victims directly. These people care about money, so ransom demands are made claiming data can properly be recovered after payment transfer. That is a false claim that is only there for encouraging victims into paying upfront.
Paying the requested fee will not get your files back. The ransom note _readme.txt delivers the message from criminals and steps that are needed for the file repair. These instructions are just another trick from this malicious group, so the contact between victims and the criminals can lead to additional issues.
The malicious ransomware is a virus that attacks Windows computers by using stealthy infiltration methods. The infection can not be stopped once it starts, and even though users are mainly responsible for this because they mostly download an email attachment or pirated software without knowing what's inside. This is one of the methods that Vlff file virus creators use to distribute the infection. These threat actors manage to inject payloads on the computer from malicious files.
If you find your computer displaying .vlff markers at the end of every file name, the threat is done with encryption procedures. This stealthy threat can cause serious issues with data and finances as well since this happens silently. If the ransom is paid, but files are still locked, you lose money and data without getting any positive results from this.
Files that are locked by Vlff ransomware can't be decrypted with any application or even opened for editing. The official decryption tool that works for everyone does not exist. If you don't take action fast, your files might get damaged permanently, and the additional changes made to the system lead to issues with performance.
| Name | Vlff file virus |
|---|---|
| Type | Ransomware, cryptovirus |
| File marker | .vlff |
| Virus family | STOP virus/ Djvu ransomware |
| Ransom note | _readme.txt |
| Ransom amount | $980/ $490 |
| Distribution | Files with malicious macros[1] can spread the infection like this. As well as the pieces in pirating software packages. Trojans and other malware are distributing the cryptovirus too |
| Decryptable? | No. The online id usage keeps the decryption tools from working |
| Removal | Threats can be terminated using AV tools and these apps can stop the malicious behavior properly |
| Repair | The infection can trigger various processes and damage on the system, so you can run FortectIntego for the file repair purposes |
The longer these malware infections run unchecked the more permanent damage may happen inside our computers. It is important you clear the infection as soon as possible. That is possible as much as it is crucial. Experts[2] always talk that removal of the malware can affect the file repair too. However, these two processes of Vlff virus file-locking and infection are separate.
Cybercriminals typically use email attachments or links in order to spread their malware. But, there are other ways you may get infected with ransomware. The threat family is known for the spreading methods that involve NBA games, cracks for the Adobe software, other popular and wanted tools, applications, video games.
Vlff ransomware virus authors claim that victims need to contact them via supportsys@airmail.cc, support @sysmail.ch emails, and provide their personal ID. The ransom note also includes the discount offer, but this could be false since decryption tools often do not even exist or can easily help you.

Dealing with ransomware infection
Experts recommend not paying the ransom, as cybercriminals might not keep their promises. This malware will lock everything up in an unreadable format, so there's no way for people to understand what they can do without using specific decryption keys. Hackers do not care about your belongings, so you need to remove the Vlff file virus to stop the malicious activities.
The unique extension is given to all encrypted files after they're locked by the virus using an army-grade encryption algorithm. The ransomware infection is a computer virus that encrypts all personal files and changes the original code, but additional issues stem from changes in the system folders and functions.
You need to remove the infection to stop the threat properly. Anti-malware tools can find the malicious files and threats on the machine, so the Vlff virus gets terminated. Applications like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes can detect[3] the threat pieces and remove any additional programs that create crucial issues with machines.
It is crucial because threats like this can leave the machine but still remains controlling processes with the leftovers of the virus. Note that virus removal and file recovery is not the same, so you must remove the Vlff ransomware virus, but the leftovers and virus damage need to get cleaned too. The AV tool also cannot recover files for you.

Recovering the system after the infection
Once a computer is infected with malware, its system is changed to operate differently. For example, an infection can alter the Windows registry database, damage vital bootup, and other sections, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software is not capable of doing anything about it, leaving it just the way it is.
Therefore, we highly recommend using a one-of-a-kind, patented technology of FortectIntego repair. Not only can it fix virus damage after the infection, but it is also capable of removing malware that has already broken into the system thanks to several engines used by the program. Besides, the application is also capable of fixing various Windows-related issues that are not caused by malware infections, for example, Blue Screen errors, freezes, registry errors, damaged DLLs, etc.

More decryption options for the family
In 2019, a new type of virus called Djvu ransomware emerged. The threat managed to come to popularity and made headlines for the constant new versions. In these recent years, the threat group released more than 400 versions. This happens weekly because the creator releases slightly changed variants every week.
This variant is related to the well-known family, and the Vlff ransomware virus is minimally altered from the previous pieces. Djvu virus was first spotted and made no difference because it was decryptable for the first part of the year. Criminals altered the coding and stopped the decryption options later on. From there, the infection became non-decryptable and started to use online IDs that determine this factor.
Offline keys used before the August 2019 were used for the decryption, and obtaining one key was useful for the whole bunch of victims because one key was used for all of the victims of the same virus. Online ids that this Vlff file virus version relies on is unique for each device, so decryption is only possible when those decryption keys get obtained by paying or with the help of malware experts.
Nevertheless, if your computer got infected with one of the Djvu variants, you should try using Emsisoft decryptor for Djvu/STOP. It is important to mention that this tool will not work for everyone – it only works if data was locked with an offline ID due to malware failing to communicate with its remote servers.
Even if your case meets this condition, somebody from the victims has to pay criminals, retrieve an offline key, and then share it with security researchers at Emsisoft. As a result, you might not be able to restore the encrypted files immediately. Thus, if the decryptor says your data was locked with an offline ID but cannot be recovered currently, you should try later. You also need to upload a set of files – one encrypted and a healthy one to the company's servers before you proceed.
- Download the app from the official Emsisoft website.

- After pressing Download button, a small pop-up at the bottom, titled decrypt_STOPDjvu.exe should show up – click it.

- If User Account Control (UAC) message shows up, press Yes.
- Agree to License Terms by pressing Yes.

- After Disclaimer shows up, press OK.
- The tool should automatically populate the affected folders, although you can also do it by pressing Add folder at the bottom.

- Press Decrypt.
From here, there are three available outcomes:
- “Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
- “Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
- “This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.
