|
## LOLBAS Project API
|
|
|
|
```python
|
|
import requests
|
|
resp = requests.get("https://lolbas-project.github.io/api/lolbas.json")
|
|
lolbas = resp.json()
|
|
# Each entry: {"Name": "Certutil.exe", "Commands": [...], "Paths": [...]}
|
|
for entry in lolbas:
|
|
for cmd in entry.get("Commands", []):
|
|
print(cmd["Command"], cmd["Category"])
|
|
# Categories: Download, Execute, Compile, Encode, ...
|
|
```
|
|
|
|
## python-evtx (Event Log Parsing)
|
|
|
|
```python
|
|
import Evtx.Evtx as evtx
|
|
from xml.etree import ElementTree as ET
|
|
|
|
with evtx.Evtx("Security.evtx") as log:
|
|
for record in log.records():
|
|
root = ET.fromstring(record.xml())
|
|
# Event ID 4688 = process creation
|
|
# Sysmon Event ID 1 = process create
|
|
```
