What is Ferosas ransomware?

Ferosas virus – a version of Djvu ransomware that promises to decrease the ransom in half if the victim contacts developers in less than 72 hours

Ferosas ransomwareFerosas ransomware is a file locking threat that comes from the Djvu family

Ferosas ransomware is a cryptovirus that makes data useless to have a reason for a ransom demand. This is a particular variant of the infamous Djvu ransomware that already is known for developing new versions continuously. There is nothing accurately different of this virus from previous variants, except the .ferosas extension it applies to encoded data. The message from developers that contains ransom demand also is the same as before. The file named _readme.txt is placed on the desktop and in various folders containing encrypted data.

Developers reveal conditions for receiving the decryption tool and claims that $980 is the price for the decryption key. Bufalo@firemail.cc, gorentos@bitmessage.ch email addresses, and @datarestore telegram account are ways for victims to communicate with the cybercriminals. According to developers, if the victim does so in less than 72 hours the ransom can get smaller by half. However, Michael Gillespie has updated the STOP virus decrypter and included .ferosas offline IDs, so your data can be decrypted using this software.

Ferosas virus is a dangerous threat which was created absolutely for beneficial purposes only. You should not believe the scammers as they might not provide you with any decryption tool at all. Do not risk to get your money swindled, and ignore the ransom message. Although these hackers allow the users to send them one small file for free decryption in order to show proof of the tool's existence and successful operation, you shouldn't pay or contact criminals in any way.

All these claims about discounts and offers for free decryption are only tricks used to convince users to transfer the urged amount of money faster. We suggest denying any offers and performing the Ferosas virus removal right away. For malware detection purposes, you should choose a reputable anti-malware program such as FortectIntego.

Ferosas ransomware virus might also eliminate Shadow Volume Copies of encrypted data which can harden the file recovery process for you. However, do not get lost as there are other methods that might be helpful and let you restore some of your individual files and documents. You can take a look at the techniques at the bottom of this page.

Ferosas virusFerosas virus is a dangerous ransomware which locks files and demands ransom

Once you remove Ferosas ransomware, do not forget to take required precautionary measures in the upcoming future. Make sure that your data files remain safe all the time. For this, use portable USB drives or remote servers such as Dropbox or iCloud where you can keep all of your documents safe and unreachable from bad actors.

The best solution for the data recovery after Ferosas ransomware encryption also is replacing affected files with data backed up on external devices or cloud services. You should focus on the malware elimination and when the system is cleaned entirely – recover your files.

Another thing you should know about Ferosas ransomware is that it might use different sneaky techniques to enter your computer system. It can be email spam and malicious attachments, infected hyperlinks or advertisements, peer-to-peer sites, and similar sources. For more accurate information, continue reading the next paragraph.

Ferosas ransomware virusFerosas is the cryptovirus based on money extortion and file-locking, so it belongs to a ransomware category.

Distribution techniques of ransomware infections

According to Virusai.lt experts,[1] ransomware viruses are widely spread by using email spamming. This means that malicious payload comes injected somewhere in a particular email message that pretends to be from an official organization or something similar. Usually, crooks plant malware into executables or hyperlinks.

Good news is that such malicious components can be avoided if you act carefully while opening email messages and especially their attachments. It is very handy to scan each attached document with an antivirus/antimalware program. However, if you see some news inbox in the spam section,[2] just delete it for your own good.

Additionally, if you want to increase the protection level of your computer system and data files, you should keep a distance from various third-party networks. Be aware of peer-to-peer sources,[3] online streaming and gaming websites, etc. Also, always keep your antivirus protection on so that it will inform you if something malicious is trying to enter the system.

Perform Ferosas ransomware removal by following our guidelines

As Ferosas ransomware appears on Windows computer only, we have provided elimination instructions for this operating system only. However, the only manual action you can perform is rebooting your computer to Safe Mode with Networking or activating the System Restore function in order to disable all activities of the ransomware virus.

All in all, Ferosas removal which is based on manual technique is not a possibility in this case as trying to remove the cyber threat on your own might only relate in more system problems and unrepairable damage. What you have to do is perform a full system scan with software such as FortectIntego, find all malware-laden[4] objects and terminate them automatically.

When Ferosas virus is removed, you can start thinking about data recovery steps. Rather than paying the demanded ransom price, take a look at the below-given data restoring software that might appear helpful. However, make sure to choose the most suitable method, otherwise, the results might not be that fascinating.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
