How to remove Phobos-Faust Ransomware and decrypt .faust files

What is Phobos-Faust Ransomware

Faust is a new ransomware variant developed by the Phobos malware group. Its purpose is to encrypt potentially important pieces of data and make victims pay money for its decryption. Along with encryption, the virus also alters the way files appear – for instance, a file originally named 1.pdf will change to something like 1.pdf.id[9ECFA84E-3421].[gardex_recofast@zohomail.eu].faust and reset its original icon after encryption. This new string of characters that ransomware appends consists of a unique victim’s ID, cybercriminals’ email address, and the .faust extension. Following the successful completion of the encryption, Faust Ransomware generates a pop-up window (info.hta) and text file (info.txt) that contain decryption guidelines.

In general, it is said victims have to establish communication with cybercriminals by writing an email message and including their personal ID. Then, extortionists will supposedly give further instructions on how and where to pay the ransom in Bitcoins. Threat actors say the price for decryption depends on how fast victims write an email to them. In addition, the information inside “info.hta” says victims can send up to 5 files before paying (less than 4Mb in total, non-archived, and without valuable information) and get them decrypted for free. Many cybercriminals behind other ransomware infections employ such offers as a guarantee that they are able to unlock the encrypted data and also that they can be trusted. In fact, although developers claim they will send the necessary deception tools after the ransom is paid, some still fool their victims and do not keep their promises regarding decryption. Despite this, initial ransomware developers are usually the only figures able to fully decrypt the blocked data. Private keys generated by Faust Ransomware are stored online and have not yet been leaked. This means third-party software is less likely to be effective in running decryption. In our guide you will find suggestions about reputable third-party recovery/decryption tools, however, their effectiveness might not be enough due to the aforementioned. The only two ways victims can recover their data at the moment are either to pay the ransom or recover the files using backup copies. However, since collaboration with cybercriminals involves a certain risk and requested amounts can be unaffordable for many users, it is recommended to use backups instead. Backups are copies of files that were saved on external storage prior to the encryption. Please note that before attempting file recovery without the help of developers, it is crucial to prevent ransomware from running on your PC – in other words, delete it. Use our guide below to do so.

How Phobos-Faust Ransomware infected your computer

Ransomware infections (and other malware) are often distributed via e-mail spam letters, trojans, deceptive third-party downloads, fake software updates/installers, backdoors, keyloggers, botnets, system exploits, and some other proliferation channels as well. Most of these channels employ phishing techniques that are designed to fool inexperienced users into opening some malicious content (usually attachments or links). For instance, ransomware or trojans can be disguised as some legitimate file (.DOCX, .XLSX, .PDF, .EXE, .ZIP, .RAR, or .JS extensions) and attached to e-mail letters that mimic the names of legal companies/entities (e.g., delivery companies, tax authorities, banks, and so forth). In order to trick inexperienced users into executing the attached content, cybercriminals may name files in click-bait ways and claim doing so is of big “importance” or “urgency”. If the attached content ends up opened according to cybercriminals’ guidelines, the contained infection will be deployed for installation on the targeted system. Thus, it is highly advised to avoid interaction with such messages. In addition, you should beware of downloading software from landing pages and third-party websites that offer pirated torrents. Running installations of software that was obtained from unofficial resources is always a risk, which has to be taken into account. Cybercriminals tend to disguise malware as some popular software to increase the chance of its proliferation.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Phobos-Faust Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice.
