FileFrozr Ransomware – Delivery Methods

The FileFrozr ransomware could be delivered via many different methods. Since it is a ransomware as a service, whoever makes a variant of it could choose to spread it with more than one method. One of the many possibilities is through document files, as the coders for the cryptovirus can put a script code for enabling macros inside them as a way of infection. Another option for delivering it to the end user could involve the spread of the payload dropper by using Exploit Kits or attaching it in spam e-mails. Also, it is good to take note of the advertising that the creator of FileFrozr is doing on numerous sites, such as sinister.ly:

The text states the following:

FILE FROZR is a great security tool that encrypts most of your files in several minutes.
Fast, stable, and affordable crypto-locker.
Auto-buy, low price, undetectable load while working, TOR support, 250+ extensions, unmatched support, multithreaded, online builder, server side obfuscation. Bypass BitDefender and Malwarebytes Anti-Ransomware.
Encrypts user data using safe implemented AES-256 and RSA-4096, each file encrypts with it own unique key.
50$ Discount on sales start!

The FileFrozr ransomware could also get delivered through social media networks and file-sharing services. Freeware programs found on the Web could be promoted as useful but still contain the downloader for the payload of the ransomware. Don’t open files when you download them, before scanning them with a security tool beforehand. That goes especially for files, which come from a suspicious source, like an e-mail with an unknown origin. You should check their size and signatures for anything that seems unusual, as well. Also, give the ransomware prevention tips a read to see how you can avoid future infections.

FileFrozr Ransomware – Technical Details

FileFrozr ransomware is a cryptovirus that is being distributed on the Internet as a RaaS (Ransomware as a Service). The following TOR web pages are being used to sell it:

The FileFrozr ransomware virus uses BitCoin and the TOR service for keeping its creator anonymous and hidden on the Web.

FileFrozr Ransomware – Encryption Process

The FileFrozr ransomware cryptovirus searches to encrypt files with more than 250 different extensions. More file extensions are quite possible to be added, depending on what files, cybercriminals wish to encrypt. The encryption process uses the AES encryption algorithm with 256-bit ciphers and RSA with 4096-bit ones. In a pending update, the cryptovirus will have a feature for offline mode, meaning that internet connection won’t be required for the malware to encrypt your data.

The FileFrozr cryptovirus might be set in the future to erase the Shadow Volume Copies from the Windows operating system by using this command:

→vssadmin.exe delete shadows /all /Quiet

Read on through and see what types of ways you can try to potentially recover some of your data.
