When to Use\n- When analyzing a RAM dump from a compromised or suspect system\n- During incident response to identify running malware, injected code, or rootkits\n- When you need to extract credentials, encryption keys, or network connections from memory\n- For detecting process hollowing, DLL injection, or hidden processes\n- When disk-based forensics alone is insufficient and volatile data is critical\n\n## Prerequisites\n- Python 3.7+ installed\n- Volatility 3 framework installed (`pip install volatility3`)\n- Memory dump in raw, ELF, or crash dump format\n- Appropriate symbol tables (ISF files) for the target OS version\n- Sufficient disk space for analysis output (2-3x memory dump size)\n- Optional: YARA rules for malware scanning in memory\n\n## Workflow\n\n### Step 1: Acquire Memory Dump and Install Volatility 3\n\n```bash\n# Install Volatility 3\npip install volatility3\n\n# Or install from source for latest features\ngit clone

Malware Investigation**\nAcquire memory with DumpIt, run pslist/pstree to identify suspicious processes, use malfind to detect injected code in svchost.exe, dump the injected memory segment, scan with YARA rules identifying Cobalt Strike beacon, extract C2 IP from netscan, correlate with network logs.\n\n**Scenario 2: Credential Theft After Breach**\nRun hashdump and lsadump to extract cached credentials, identify mimikatz execution in cmdline output, check for lsass.exe memory dumps in filesystem artifacts, correlate with lateral movement evidence in network connections.\n\n**Scenario 3: Rootkit Detection**\nCompare pslist (uses EPROCESS linked list) with psscan (pool scanning) to find unlinked processes, check modules vs modscan for hidden kernel drivers, examine SSDT for hooks redirecting system calls, dump suspicious modules for static analysis.\n\n**Scenario 4: Ransomware Incident Recovery**\nExtract encryption keys from ransomware process memory before system shutdown, identify the ransomware variant using YARA, find the initial execution point through command line artifacts, map lateral movement via network connections.\n\n## Output Format\n\n```\nMemory Forensics
