Why is there no solution to certain ransomware?

Some ransomware types are impossible to decrypt due to their sophisticated encryption algorithms and techniques that make it extremely difficult to break. They may use strong encryption methods like RSA or AES encryption, which require a decryption key that only the attackers possess. Additionally, some ransomware variants keep evolving and using unique encryption keys for each attack, making it nearly impossible to create a universal decryption tool. The complexity and constantly changing nature of these ransomware strains make them very challenging to overcome for security experts and victims alike.
