What has contributed to the increased complexity of ransomware attacks?

The increased complexity of ransomware attacks can largely be attributed to the development of sophisticated encryption methods. Cybercriminals now utilize advanced algorithms that effectively lock users out of their data, making it impossible to recover files without the decryption key. This level of encryption not only enhances the effectiveness of the attack but also makes it more challenging for victims to regain access to their files without paying the ransom.

As threats evolve, attackers adapt by employing more sophisticated techniques to ensure their malicious software is effective and difficult to thwart. Encryption is a critical component of this strategy, as it directly impacts the ability of victims to recover their data independently. The other options, while they may contribute to a broader context of cybersecurity challenges, do not specifically address the core factor driving the complexity inherent in ransomware attacks.
