Spring ransomware is a malicious program stemming from the notorious CONTI ransomware family. It encrypts user files, appending a unique extension to them and demanding a ransom for decryption.

Spring Ransomware: Overview

Spring ransomware is designed to lock victims’ data and extort payments for decryption tools. Upon infection, it encrypts files and appends the .FIND_EXPLAIN.TXT.spring extension. For example, a file named image.jpg becomes image.jpg.FIND_EXPLAIN.TXT.spring. The ransomware also generates a ransom note, EXPLAIN.txt, containing instructions for victims.

The note emphasizes that victims must contact the attackers via TOX or email, submit three encrypted files for testing, and then pay the ransom for the decryption software. Victims are warned against renaming files or using third-party tools, as these actions may lead to permanent data loss.
