What is Legacy ransomware? And how does it carry out its attack?

Legacy ransomware is a new data-encrypting virus discovered recently that adds a “.legacy” extension to each file it encrypts. It also happens to be a new variant of Nordfox ransomware. Like its predecessor, it is created to lock valuable files in a computer and demand ransom from its victims.

Legacy ransomware begins its attack with a data harvesting module used to collect data in the system. Depending on its exact configuration, it can harvest a limited amount of information or extensive amount of information from the infected computer. The harvested data is then used by its stealth protection component which can hide its presence in the system. This is done by scanning the system for application strings, deleting files used by these apps and by disabling their real-time search engines. Aside from that, this crypto-malware can also disable debug environments and virtual machines which are both used in analyzing the strains.

Moreover, Legacy ransomware also alters the Windows Registry making it a persistent threat that you just can’t easily get rid of. As a result, it can now run on every system startup. After it completes modifying the settings on your computer, it starts looking for files with specific formats and encrypts them using both the AES and RSA encryption algorithms. Following data encryption, it adds the “.legacy” extension to every encrypted file and opens a text file named “HOW TO BACK YOUR FILES.txt” which contains the following message:

“All your important files are encrypted.
To recover encrypted files, you need:

How does Legacy ransomware spread over the web?

Legacy ransomware might circulate the internet using malware-laden spam emails.
