Ransomware — CompTIA CySA+ (CS0-003) Practice Questions

Ransomware is a class of malware that encrypts victim data or systems and demands payment in exchange for a decryption key, and it represents one of the most operationally disruptive threats analysts encounter. The CySA+ exam addresses ransomware within both the incident response and vulnerability management domains, testing how analysts identify early indicators of compromise such as unusual file access patterns or lateral movement, as well as how they contain and recover from an active ransomware event. Candidates are expected to understand the role of offline and immutable backups, the risks of paying ransoms, and how threat intelligence feeds inform detection of known ransomware families. Ransomware scenarios frequently appear in exam questions because they require applying multiple CySA+ skills simultaneously.
