Abstract
One example method includes detecting a file access process, such as a write operation performed by a ransomware process, directed to a file, based on the detecting, incrementing a counter, checking to determine if the counter exceeds a defined threshold, and when the counter exceeds the defined threshold, creating a backup of the file. The backup file may be a read-only file, and may expire, and be deleted, at a particular time, or after the passage of a period of time.
