This particular ransomware renames encrypted files by appending the ".dark" extension. For example, "1.jpg" is renamed to "1.jpg.dark", "2.jpg" to "2.jpg.dark", and so on.

It also creates the "Important.txt" file in all folders that contain encrypted data. The file contains a ransom message with instructions about how to pay the ransom and contact the attackers.

What is the Erica ransomware?

Discovered by Petrovic, Erica is data-encrypting ransomware. Systems infected with this malware have their files locked and renamed, and users receive ransom demands for decryption of files to regain access to their data.

During the encryption process, affected files are appended with a random character string. For example, "1.jpg" would appear as something similar to "1.jpg.agl-b3e-5xu" following encryption. After this process is complete, ransom-demand messages in "Readme.[random_string].txt" files are dropped into compromised folders.
