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 ransomware
Ferosas 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.

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 Reimage.

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.

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 virus
Ferosas 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.
