Uptycs researchers have recently discovered a new ransomware that attacks Linux systems. Its name, ELF ransomware.
Ransomware creators usually target Windows operating systems. But this time, technology lovers’ favorite OpenSource system has been exposed to its vulnerability.
ELF ransomware, in reference to “Executable and Linkable Format” files, is able to encrypt files within the Linux system based on the folder path provided.
Having this information about the folder location, the ELF ransomware then begins encrypting the files present within the folder by adding the .crypted extension to the filename.
Once encrypted, the file becomes inaccessible to the user, and then the last step begins. A file called README_TO_RESTORE is created in the environment containing the necessary information for the victim to establish contact with the attacker.
Incidentally, the content of this file is identical to the README file of the DarkAngels ransomware. This similarity leads researchers to think that the ELF ransomware may be a version of DarkAngels aimed at diversifying the target operating systems.
In May, DarkAngels had been designed to infect Windows environments, and we now know that the ELF ransomware targets Linux environments.
Unfortunately, with the exponential increase in ransomware attacks, it is becoming increasingly complex to escape fatality. That is why it is important to know who to rely on when something like this happens.
