Hunting For Shadow Copy Deletion Hunt for Volume Shadow Copy deletion activity that indicates ransomware preparation or anti-forensics by monitoring vssadmin, wmic, and PowerShell shadow copy commands.
mukul975 4,535 스타 2026. 4. 6. When to Use
When proactively hunting for indicators of hunting for shadow copy deletion in the environment
After threat intelligence indicates active campaigns using these techniques
During incident response to scope compromise related to these techniques
When EDR or SIEM alerts trigger on related indicators
During periodic security assessments and purple team exercises
Prerequisites
EDR platform with process and network telemetry (CrowdStrike, MDE, SentinelOne)
SIEM with relevant log data ingested (Splunk, Elastic, Sentinel)
Sysmon deployed with comprehensive configuration
Windows Security Event Log forwarding enabled
Threat intelligence feeds for IOC correlation
Workflow
Formulate Hypothesis : Define a testable hypothesis based on threat intelligence or ATT&CK gap analysis.Identify Data Sources : Determine which logs and telemetry are needed to validate or refute the hypothesis.
