A new version of the CryptoWall Malware is making it an even bigger threat to your data. CryptoWall 4.0 has been released, displaying a redesigned ransom note, new filenames, and more encryption for its victims. In previous versions, files were encrypted, making them unusable to the malware’s victim. Now the names of the files are also being encrypted, making it more difficult to know what files need to be recovered.
CryptoWall 4.0 also has a new ransom note, and has changed its name to “help_your_files.html”. The malware pretends to be a resume inside zipped e-mail attachments. As with previous versions, CryptoWall encrypts its victims’ data until a ransom is paid through bitcoin. The only alternative to recover your data is with a backup system.
Be aware of the threat to your data, and only open messages and attachments from senders you know. Feel free to contact us to speak to us about the best backup system for your needs.
