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

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 – Encryption Process

The FileFrozr ransomware cryptovirus searches to encrypt files with more than 250 different extensions.
