What is FAST Ransomware

FAST Ransomware is a type of malware that our research team recently discovered while investigating submissions on the VirusTotal website. This particular malicious program is classified as ransomware, which means it is designed to encrypt data on a victim’s computer and demand a ransom in exchange for its decryption. When we tested the ransomware on our own machine, we observed that it encrypted files and modified their filenames. The original file titles were altered by appending the cyber criminals’ email address, a unique victim ID, and the .FAST extension. For example, a file named sample.pdf would appear as sample.pdf.EMAIL=[fastdec@tutanota.com]ID=[RANDOM].FAST after encryption. After completing the encryption process, FAST ransomware dropped a ransom note titled #FILEENCRYPTED.txt onto the victim’s desktop.

It is important to note that removing FAST ransomware from your operating system will prevent further file encryption, but it will not restore the already affected data. The only solution for data recovery is to restore the files from a backup if one was created beforehand and stored in a separate location. Alternatively, you can try high-quality file recovery programs, for example Stellar Data Recovery Pro. To ensure the safety of your data, we highly recommend maintaining backups in multiple locations, including unplugged storage devices and remote servers. This will help protect your files in case of a ransomware attack.

How FAST Ransomware infected your computer

Ransomware, including FAST, primarily infects computers through phishing and social engineering techniques. Malicious software is often disguised as legitimate programs or bundled with media files. These malicious files can take various formats, such as executables (.exe, .run), archives (RAR, ZIP), documents (PDF, Microsoft Office), JavaScript, and more. When an infected file is opened, it triggers the download and installation of the malware.

The most common methods used for spreading ransomware include drive-by downloads, which are stealthy and deceptive, as well as malicious attachments and links in spam emails, direct messages, private messages, and text messages. Online scams, malvertising (malicious advertisements), untrustworthy download sources like freeware and file-hosting websites, peer-to-peer (P2P) sharing networks, illegal software activation tools (“cracks”), and fake updates are also commonly employed. Furthermore, some ransomware strains are capable of self-propagation through local networks and removable storage devices like external hard drives and USB flash drives.
