Windows Plugins — Full Reference

Process Analysis

# List processes (flat, fast)
python3 vol.py -f memory.raw windows.pslist

# Process tree (shows parent/child relationships)
python3 vol.py -f memory.raw windows.pstree

# Process scan (finds hidden/unlinked processes)
python3 vol.py -f memory.raw windows.psscan

# Compare pslist vs psscan — differences = hidden processes
diff <(python3 vol.py -f memory.raw windows.pslist 2>/dev/null | awk '{print $2}' | sort) \
     <(python3 vol.py -f memory.raw windows.psscan 2>/dev/null | awk '{print $2}' | sort)

# Detailed process info (PID, PPID, handles, threads, path)
python3 vol.py -f memory.raw windows.cmdline     # command line of each process
python3 vol.py -f memory.raw windows.dlllist     # DLLs loaded per process
python3 vol.py -f memory.raw windows.handles     # open handles (files, registry, mutexes)

# Filter by PID
python3 vol.py -f memory.raw windows.dlllist --pid 1234
python3 vol.py -f memory.raw windows.handles --pid 1234

Key fields in pslist:

• PID / PPID — process and parent ID
• ImageFileName — process name (max 15 chars — truncated!)
• CreateTime — when process started
• Offset(V) — virtual memory address

Suspicious indicators:

• svchost.exe with no parent services.exe
• explorer.exe with parent other than userinit.exe
• Duplicate lsass.exe, csrss.exe, smss.exe
• Process name with extra space or unicode lookalike

Fields: LocalAddr, LocalPort, ForeignAddr, ForeignPort, State, PID, Owner, Created

Memory Region Analysis

# Virtual address descriptors (mapped memory regions per process)
python3 vol.py -f memory.raw windows.vadinfo --pid 1234

python3 vol.py -f memory.raw windows.malfind --dump --pid 1234

# Output: PID, process name, start address, VAD flags, MZ header bytes
# MZ header in rwx region = classic injected PE

Malfind output pattern — injection:

4608    explorer.exe    0x400000  PAGE_EXECUTE_READWRITE  MZ....

DLL and Module Analysis

# Loaded DLLs per process

Investigation Workflows

Workflow 1: Full Windows triage

MEM="memory.raw"
vol() { python3 vol.py -f "$MEM" "$@" 2>/dev/null; }

# Phase 1 — baseline
vol windows.pslist > pslist.txt
vol windows.psscan > psscan.txt
vol windows.pstree
vol windows.netscan > netscan.txt
vol windows.cmdline > cmdline.txt

# Phase 2 — anomaly hunt
diff <(awk '{print $2}' pslist.txt | sort) <(awk '{print $2}' psscan.txt | sort)
grep -E "443|8080|4444|1337" netscan.txt        # suspicious ports
grep -E "Temp|AppData|ProgramData" cmdline.txt  # suspicious paths

# Phase 3 — injection check
vol windows.malfind > malfind.txt
grep -E "MZ|PAGE_EXECUTE_READWRITE" malfind.txt

# Phase 4 — credentials
vol windows.hashdump
vol windows.cachedump
vol windows.lsadump

# Phase 5 — artifacts
vol windows.filescan > filescan.txt
grep -iE "flag|secret|password|\.txt|\.docx" filescan.txt

Workflow 2: Find and extract suspicious process

# 1. Identify suspicious PID
python3 vol.py -f memory.raw windows.psscan 2>/dev/null | grep -i "cmd\|powershell\|wscript"

# 2. Get command line
python3 vol.py -f memory.raw windows.cmdline --pid 1234

# 3. Check injected memory
python3 vol.py -f memory.raw windows.malfind --pid 1234

# 4. Dump process binary
python3 vol.py -f memory.raw windows.procdump --pid 1234

# 5. Check strings in dumped binary
strings -n 8 pid.1234.*.exe | grep -iE "flag|key|pass|http|C2"

Workflow 3: File extraction from memory

# Find files of interest
python3 vol.py -f memory.raw windows.filescan 2>/dev/null | grep -iE "flag|\.txt|\.zip|interesting"

# Get virtual address from output (3rd column)
# Example: 0xce89890 .\Users\user\Desktop\flag.txt

# Dump it
python3 vol.py -f memory.raw windows.dumpfiles --virtaddr 0xce89890

# If dump produces .dat file, check type
file file.0xce89890.dat
strings file.0xce89890.dat

Workflow 4: Linux credential recovery

# Bash history from memory
python3 vol.py -f memory.raw linux.bash 2>/dev/null

# Find interesting env vars
python3 vol.py -f memory.raw linux.envars 2>/dev/null | grep -iE "pass|key|flag|secret|token"

# Find /etc/shadow in memory
python3 vol.py -f memory.raw linux.find_file --path /etc/shadow
python3 vol.py -f memory.raw linux.find_file --inode <inode_from_above>

Quick Reference — Common Incident Patterns

| Goal | Command | |------|---------| | Find hidden processes | windows.psscan vs windows.pslist diff | | Find C2 connections | windows.netscan → look for unusual foreign IPs/ports | | Find injected shellcode | windows.malfind → MZ header in RWX VAD | | Recover deleted file | windows.filescan → windows.dumpfiles --virtaddr | | Dump credentials | windows.hashdump + windows.cachedump + windows.lsadump | | Find target string in memory | windows.filescan grep indicator, then dumpfiles | | Bash history | linux.bash | | Suspicious env var | linux.envars grep key/flag/pass | | Network connections | linux.netstat / windows.netscan | | Process command line | windows.cmdline |
