Iiss ransomware is a cyber threat that stems from a prominent crypto-malware family Djvu

Iiss ransomware

Iiss ransomware is a type of cryptovirus that is classified as a money-extortion-based threat controlled by malicious actors.[1] These threats are known for accessing user machines without permission and encrypting all files on them. This way, cybercriminals behind the malware can ask for a ransom payment in return for a unique key. This is one of the newest versions in Djvu ransomware family that stems from STOP ransomware, known for a long time already. However, this version is not the last probably, because criminals release a new variant once a week, at least.

The malware encrypts all files with the help of a powerful encryption algorithm RSA and marks files using .iiss extension once the process of locking those pieces of documents, pictures, archives gets done. For example, a file “picture.jpg” is turned into a “picture.jpg.iiss,” making encoded data unusable. Once encryption is finished, the Iiss virus drops a ransom note _readme.txt, which is placed on the desktop and/or other locations within the computer. In the note, attackers write that they are willing to provide the decryption tool for a payment of $980 in return.

This sum should be transferred to Bitcoin cryptocurrency because it is a popular way to make a profit that hackers tend to rely on. The ransom note file also provides contact emails helpmanager@mail.ch, restoremanager@airmail.cc that you should use to get a hold of criminals. However, it is not recommended to pay the ransom due to the high risk of money loss and the possibility to suffer from permanent .iiss virus damage to the machine.

Name Iiss ransomware
Family Djvu/ Stop virus family 
Extension Files appended with .iiss extension, e.g., “picture.jpg” is turned into “picture.jpg.iiss”
Ransom note  _readme.txt
File marker .iiss
Contact emails helpmanager@mail.ch, restoremanager@airmail.cc
Distribution Threat spreads using pirating platforms that people use to get cracks, illegal software activation numbers, game cheats[2]
File recovery  options

If no backups or file copies are available, recovering data is almost impossible. Nonetheless, we suggest you try alternative methods that could help you in some cases: media file repair tool; Emsisofts' decrypter; Windows OS options listed below.

Malware removal  Perform a full system scan with powerful security software to remove Iiss ransomware
System fix Malware can seriously tamper with Windows systems, causing errors, crashes, and other stability issues after it is terminated even. To recover after the attack and repair the OS, avoid malware reinstallation, we recommend scanning it with the FortectIntego tool that can indicate or even fix the damage

Iiss ransomware is a virus designed to lock videos, music, and other files on your computer and hold them hostage until a ransom is paid. However, this is not the best option. Especially when it comes to the already known family of crypto-extortion malware. You should at least check if Emsisofts' decrypter can work and this way, determine if you need to search for other options. 

Unfortunately, Iiss ransomware is one o the newest versions, so offline IDs are less likely used in this case. Online IDs mean that your unique decryption key is automatically formed when a virus connects to a remote server, so there are no identical decryption keys.

File recovery becomes more difficult unless you have reputable data backups stored on an external drive or remotely, so viruses can't encode them. So experts[3] recommend relying on professional tools or system functions when restoring encrypted files, so you can avoid getting more malware in addition to Iiss virus or trigger damage to your file backups.

Your personal ID

This virus derives from a well-known family, which was first spotted in 2016 and improved tactics multiple times over the year 2019 and since then released multiple variants, including .efji, .erif, .lyli. In this article, we will provide alternative methods for .iiss file recovery and safe ways of deleting the infection from a Windows computer. This is the virus that mainly targets such operating systems.

Iiss ransomware removal is possible with tools like anti-malware or security programs, but even SpyHunterCombo Cleaner or MalwarebytesMalwarebytes cannot ensure that your encrypted files will get restored easily. You need to fight malware with proper applications and then rely on file recovery software or clear the machine and replace affected files using safe copies.

Removing .Iiss virus is not the same as recovering ransomware encoded files

Since there are no official decryption tools and previously known STOPDecrypter is no longer supported, restoring Iiss ransomware files is related to your file backup habits. If you keep your file copies for data recovery options in the future and do that more often, you might have needed documents or images, video files archived. 

However, you need to be sure that you remove Iiss ransomware completely before adding any files on the computer or installing additional programs on the system. You can suffer from secondary encryption round if you haven't terminated the threat properly.

Iiss file virus

There are possible ways to restore .Iiss files when ransomware is eliminated. It involves functions that Windows OS can offer, but malware can affect the machine's particular parts to affect the persistence and keep users away from getting their files back. Running a tool that can detect[4] ransomware and remove it is the first step.

The second step in the recovery from Iiss ransomware attack is file repair that involves software like FortectIntego, capable of finding and repairing system folders, files, functions, and features. Then you either replace files with copies or trust tools that can recover individual data for you without paying virus creators.

Focus on Iiss virus elimination procedures and make sure to clear the PC before the file recovery

Iiss ransomware virus can become persistent and extremely intrusive or dangerous when malicious actors manage to alter particular settings or files on the system. You should consider all these changes and virus damage when you are dealing with the threat of such type. 

There are little to no options for particular data recovery and Iiss ransomware removal procedures because you can get rid of the malware, but the encrypted data remains changed. Anti-malware tools like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes can run on the machine and eliminate the infection, but your files still need to get repaired separately.

When you remove Iiss ransomware from the machine, pay attention to other needed procedures because anti-malware tools are not the only ones that can do everything on the computer. AV vendors only provide virus termination, so you need some program like FortectIntego for file repair in the system and functions recovery. Then third-party programs or system functions can help with the data restoring.
