摘要： Solutions for rapid ransomware detection and recovery include: receiving a first set of in-memory changed data blocks; identifying, within the first set of in-memory changed data blocks, a second set of in-memory changed data blocks addressed for storage within a file index for a virtual machine (VM) disk; determining, relative to a change history of the file index, an anomalous condition; based on at least determining the anomalous condition, identifying a third set of blocks within the file index that are changed between two versions of the VM disk; determining that changes in the third set of blocks indicate ransomware; and based on at least determining that changes in the third set of blocks indicate ransomware, generating an alert. Machine learning (ML) models may perform anomaly/ransomware detection. Remediation activities may include disk restoration storing the VM memory.
