What is AnonFive ransomware virus?

AnonFive virus attempts to debut in ransomware industry

AnonFive virus does not differ from standard ransomware-type computer programs that are created to be used as extortion tools[1]. There has been a tendency to create new ransomware programs based on open-source educational ransomware projects[2], and AnonFive ransomware is designed the same way, too. It turns out to be another copy of HiddenTear ransomware[3], which has been released “for educational purposes.” Sadly, the virus’ code was quickly exploited by bad people all over the world – new HiddenTear spin-offs appear almost every week. Speaking of AnonFive malware, we have to say that it seeks to encode all files on the target system. It hacks[4] user’s system and starts searching for files that have extensions included in the virus’ target list. Once it locates a target file, it applies a sophisticated encryption algorithm to it. This process can be compared to password settings, except that encrypted files can be opened only with a unique decryption key, which the ransomware transfers to private servers of cyber criminals. During the encryption, AnonFive appends .anonfive file extensions to encrypted files. This is a typical trick used by almost all ransomware viruses. It is known that the ransomware is developed by someone whose nickname is Cyryx, but no additional details about this person were found so far.

Ransomware developers are basically wicked individuals who want to earn money by extorting people who use unprotected computers. We do not recommend you to respond to their commandments to give money in exchange to access to your files. The author or AnonFive malware creates READ_IT.txt ransom note, in which it lays down possible data decryption conditions. The criminal is going to ask you to buy a Bitcoin or two and send them to his/her virtual wallet. Sadly, you cannot track this cyber criminal via Bitcoin payment system – it has successfully, although indirectly helped many cyber criminals to get rich without being caught[5]. We suggest you demotivate the criminal by refusing to pay the ransom. You can try HiddenTear decryption tool to recover your files, use a backup or other data recovery measures described below AnonFive removal tutorial. Please, do not try to eliminate the virus on your own – it is not a simple program, and it is not enough to delete some files manually. Programs like FortectIntego or SpyHunter 5Combo Cleaner can help you to remove AnonFive malware precisely.

AnonFive distribution peculiarities exposed

We have no doubts that you wonder how did AnonFive hijack your computer system (if you haven’t figured it out on your own yet). Considering that the virus is based on another ransomware source code, we have no doubts that it was developed by a novice programmer. Therefore, we can already rule out advanced malware distribution techniques – use of exploit kits and malvertising. Therefore, we strongly believe that AnonFive ransomware is being distributed via infectious email attachments, which work like bait. When unsuspecting victims recklessly open these attachments, the malware quickly invades the system and converts files into broken pieces of data that cannot be opened. We must warn you that cyber criminals now can inject malicious scripts into Word documents or PDFs, so be careful! Scammers no longer need to use .exe files, because many computer users are aware that these are executive files used to launch programs.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

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

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
