- Add validated mitre_attack frontmatter to all 754 skills (286 distinct techniques), verified against MITRE ATT&CK v19.1 via the official mitreattack-python library: 0 revoked, deprecated, or invalid IDs - Curate precise per-skill technique IDs for forensics, malware-analysis, threat-intel, and red-team skills (e.g. DCSync -> T1003.006, Kerberoasting -> T1558.003, Pass-the-Ticket -> T1550.003) - Reconcile v19.1 tactic restructuring: Defense Evasion split into Stealth (TA0005) and Defense Impairment (TA0112); revoked T1562.* family and T1070.001/.002 remapped to active equivalents (T1685.*) - Normalize word-split tags across 35 skills (remove filename-derived stopword tags, add semantic cybersecurity tags) - Add api-reference.md for 3 skills that were missing it - Update README ATT&CK section with accurate v19.1 tactic distribution

# Analyzing Memory Forensics with LiME and Volatility
|
|
|
|
|
|
## When to Use
|
|
|
|
- When investigating security incidents that require analyzing memory forensics with lime and volatility
|
|
- When building detection rules or threat hunting queries for this domain
|
|
- When SOC analysts need structured procedures for this analysis type
|
|
- When validating security monitoring coverage for related attack techniques
|
|
|
|
## Prerequisites
|
|
|
|
- Familiarity with security operations concepts and tools
|
|
- Access to a test or lab environment for safe execution
|
|
- Python 3.8+ with required dependencies installed
|
|
- Appropriate authorization for any testing activities
|
|
|
|
## Instructions
|
|
|
|
Acquire Linux memory using LiME kernel module, then analyze with Volatility 3
|
|
to extract forensic artifacts from the memory image.
|
|
|
|
```bash
|
|
# LiME acquisition
|
|
insmod lime-$(uname -r).ko "path=/evidence/memory.lime format=lime"
|
|
|
|
# Volatility 3 analysis
|
|
vol3 -f /evidence/memory.lime linux.pslist
|
|
vol3 -f /evidence/memory.lime linux.bash
|
|
vol3 -f /evidence/memory.lime linux.sockstat
|
|
```
|
|
|
|
```python
|
|
import volatility3
|
|
from volatility3.framework import contexts, automagic
|
|
from volatility3.plugins.linux import pslist, bash, sockstat
|
|
|
|
# Programmatic Volatility 3 usage
|
|
context = contexts.Context()
|
|
automagics = automagic.available(context)
|
|
```
|
|
|
|
Key analysis steps:
|
|
1. Acquire memory with LiME (format=lime or format=raw)
|
|
2. List processes with linux.pslist, compare with linux.psscan
|
|
3. Extract bash command history with linux.bash
|
|
4. List network connections with linux.sockstat
|
|
5. Check loaded kernel modules with linux.lsmod for rootkits
|
|
|
|
## Examples
|
|
|
|
```bash
|
|
# Full forensic workflow
|
|
vol3 -f memory.lime linux.pslist | grep -v "\[kthread\]"
|
|
vol3 -f memory.lime linux.bash
|
|
vol3 -f memory.lime linux.malfind
|
|
vol3 -f memory.lime linux.lsmod
|
|
```
