How is ransomware detected?
Ransomware detection involves using a mix of automation and malware analysis to discover malicious files early in the kill chain. But malware isn't always easy to find. Adversaries often hide ransomware within legitimate software to escape initial detection.
Do ransomware attackers get caught?

Technology is important, but the old expression that "humans are the weakest link" in any cybersecurity program seems truer than ever. Employee training is a critical line of defense as cybercriminals continue to prey on remote workers.
How do you detect if a file is encrypted?
You look at the entropy of the file. If the entropy is high, then it's likely encrypted. You can use tools like binwalk to determine the entropy. A consistent, high entropy indicates that the file is likely encrypted.
