analyzing-malware-in-memory-with-volatility3

Analyzes a memory image with Volatility 3 to find malware: rogue processes, injected code, suspicious network connections, loaded modules, and persistence, then extracts artifacts for further analysis. Activates for requests to do memory forensics, analyze a RAM dump, or hunt malware in memory with Volatility.

Analyzing Malware in Memory with Volatility 3

When to Use

  • You have a RAM image from a suspected-infected host and need to find malicious activity.
  • Disk artifacts are insufficient (fileless/in-memory malware) and you need volatile evidence.
  • You want to extract injected code, command lines, or network connections for analysis.

Do not use Volatility plugins blindly without an order of investigation — start broad (processes, network) before deep per-process dumps.

Prerequisites

  • Volatility 3 (pip install volatility3) with appropriate symbol tables.
  • A memory image acquired with a sound tool (WinPmem, LiME, or hypervisor snapshot).
  • Knowledge of the source OS/version to select the right symbols.

Safety & Handling

  • Work on a copy of the image; preserve the original with a recorded hash.
  • Treat any dumped executable region as a live sample — store and handle it accordingly.

Workflow

Step 1: Enumerate processes and spot anomalies

vol -f memory.raw windows.pslist
vol -f memory.raw windows.pstree

Look for unusual parents (Word spawning cmd/powershell), masquerading names (scvhost.exe), processes with no disk path, and orphaned children.

Step 2: Hunt injected code

vol -f memory.raw windows.malfind

malfind flags private, executable, RWX regions with no backing file — classic injection. Note the PID and base address for dumping.

Step 3: Review network connections

vol -f memory.raw windows.netscan

Correlate listening/established connections with suspicious PIDs and the C2 endpoints from other analysis.

Step 4: Check modules, handles, and persistence

Examine loaded DLLs (windows.dlllist), services, and registry (windows.registry.*) for persistence and unexpected modules.

Step 5: Dump artifacts

Dump the suspicious process or injected region for static/RE analysis:

vol -f memory.raw windows.dumpfiles --pid <pid>

The helper script parses Volatility's JSON renderer output to highlight injection candidates.

vol -f memory.raw -r json windows.malfind | python scripts/analyst.py malfind -

Validation

  • Injection candidates from malfind correspond to anomalous processes from pstree.
  • Network connections map to known C2 or the sample's extracted config.
  • Dumped regions disassemble into meaningful code, not random bytes.

Pitfalls

  • Wrong symbols/profile producing empty or garbage results — confirm OS build first.
  • Treating every RWX region as malicious; some legitimate JIT engines use RWX. Corroborate.
  • Forgetting to hash and preserve the original image before analysis.

References

  • See references/api-reference.md for the malfind output parser.
  • Volatility 3 documentation and memory-forensics concepts (linked in frontmatter).
