Decoy File Ransomware Detection Mechanism

The system performs preliminary actions by storing decoy files on the storage device before actual ransomware attacks occur. These decoy files are positioned to be easily targeted by ransomware, allowing the system to detect attacks in their early stages before sensitive data is compromised. The process analysis and classification mechanisms are pre-configured to monitor these decoy files and identify suspicious encryption activities.

Decoy files serve as intermediary objects between the ransomware threat and the detection system. Instead of directly monitoring all files on the storage device, the system uses these intermediary decoy files as proxies to detect ransomware behavior. The process analysis component acts as another intermediary, mediating between the file system operations and the security response mechanisms.

The system applies local quality by performing process analysis selectively rather than uniformly across all processes. Process analysis is concentrated on those processes that exhibit suspicious behavior patterns, such as attempting to enumerate or modify decoy files. Benign processes that show normal behavior patterns are allowed to execute without extensive analysis, thereby reducing overall processing time while maintaining high detection accuracy for malicious activities.

The system implements partial action by applying full process analysis only when necessary - specifically when there is indication of suspicious behavior. For routine operations, the system uses lighter monitoring approaches. This selective application of analysis depth allows the system to maintain high detection accuracy for malicious processes while minimizing the time overhead for legitimate processes.
