Plus depuis ce dépôt abusing-dpapi-for-credential-access Extract and decrypt Windows DPAPI-protected secrets (Credential Manager, browser logins/cookies, Wi-Fi credentials, KeePass keys) online or offline using SharpDPAPI, SharpChrome, Mimikatz, or Impacket's dpapi.py, including domain-wide decryption via the DPAPI backup key. Use during authorized red-team credential-access engagements after gaining a foothold or when triaging DPAPI blobs pulled from a host.
abusing-shadow-credentials-for-privesc Take over Active Directory accounts by writing attacker-controlled public keys to msDS-KeyCredentialLink (Shadow Credentials) with pyWhisker, Whisker, or Certipy, then authenticate via PKINIT to recover the target's NT hash without a password reset. Use when BloodHound shows GenericWrite/GenericAll/AddKeyCredentialLink over a target, as a stealthier alternative to ForceChangePassword, during authorized red-team engagements.
acquiring-disk-image-with-dd-and-dcfldd Create forensically sound bit-for-bit disk images with dd or dcfldd on a Linux forensic workstation, preserving evidence integrity through hash verification (MD5/SHA) during acquisition. Use when imaging a suspect drive, USB device, or memory card for investigation, preserving volatile disk evidence during incident response, or producing a verified copy for legal or law-enforcement proceedings before any destructive analysis.

Implementing SOAR Automation with Phantom
When to Use
Use this skill when:
SOC teams need to automate repetitive triage and enrichment tasks for high-volume alerts
Manual response times exceed SLA requirements and automation can reduce MTTR
Multiple security tools (SIEM, EDR, firewall, TIP) need orchestrated response actions
Playbook standardization is required to ensure consistent analyst response across shifts
Do not use for fully autonomous containment without human approval gates — always include analyst decision points for high-impact actions like account disabling or host isolation.
Prerequisites
Splunk SOAR (Phantom) 6.x+ deployed with web interface access
App connectors configured: VirusTotal, CrowdStrike, ServiceNow, Active Directory, Splunk ES
Splunk ES integration for ingesting notable events as SOAR events
API credentials for each integrated tool stored in SOAR asset configuration
Python knowledge for custom playbook actions
Workflow
Step 1: Configure Asset Connections
Set up integrations with security tools via SOAR Apps:
VirusTotal Asset Configuration:
{
"app" : "VirusTotal v3" ,
"asset_name" : "virustotal_prod" ,
"configuration" : {
"api_key" : "YOUR_VT_API_KEY" ,
"rate_limit" : true ,
"max_requests_per_minute" : 4
} ,
"product_vendor" : "VirusTotal" ,
"product_name"
:
"VirusTotal"
}
CrowdStrike Falcon Asset:
{
"app" : "CrowdStrike Falcon" ,
"asset_name" : "crowdstrike_prod" ,
"configuration" : {
"client_id" : "CS_CLIENT_ID" ,
"client_secret" : "CS_CLIENT_SECRET" ,
"base_url" : "https://api.crowdstrike.com"
}
}
{
"app" : "Active Directory" ,
"asset_name" : "ad_prod" ,
"configuration" : {
"server" : "dc01.company.com" ,
"username" : "soar_service@company.com" ,
"password" : "SERVICE_ACCOUNT_PASSWORD" ,
"ssl" : true }
}
Step 2: Build Phishing Triage Playbook Create an automated phishing response playbook in Python (Phantom playbook format):
"""
Phishing Triage Automation Playbook
Trigger: New phishing email reported via Splunk ES notable or email ingestion
"""
import phantom.rules as phantom
import json
def on_start (container ):
artifacts = phantom.get_artifacts(container_id=container["id" ])
for artifact in artifacts:
artifact_type = artifact.get("cef" , {}).get("type" , "" )
if artifact_type == "url" :
phantom.act("url reputation" , targets=artifact,
assets=["virustotal_prod" ],
callback=url_reputation_callback,
name="url_reputation" )
elif artifact_type == "hash" :
phantom.act("file reputation" , targets=artifact,
assets=["virustotal_prod" ],
callback=hash_reputation_callback,
name="file_reputation" )
elif artifact_type == "ip" :
phantom.act("ip reputation" , targets=artifact,
assets=["virustotal_prod" ],
callback=ip_reputation_callback,
name="ip_reputation" )
def url_reputation_callback (action, success, container, results, handle ):
if not success:
phantom.comment(container, "URL reputation check failed" )
return
for result in results:
data = result.get("data" , [{}])[0 ]
malicious_count = data.get("summary" , {}).get("malicious" , 0 )
total_engines = data.get("summary" , {}).get("total_engines" , 0 )
if malicious_count > 5 :
phantom.act("block url" , targets=result,
assets=["palo_alto_prod" ],
name="block_malicious_url" )
phantom.set_severity(container, "high" )
phantom.set_status(container, "open" )
phantom.comment(container,
f"URL flagged by {malicious_count} /{total_engines} engines. "
f"Blocked on firewall. Escalating to Tier 2." )
phantom.act("create ticket" , targets=container,
assets=["servicenow_prod" ],
parameters=[{
"short_description" : f"Phishing - Malicious URL detected" ,
"urgency" : "2" ,
"impact" : "2"
}],
name="create_incident_ticket" )
elif malicious_count > 0 :
phantom.promote(container, template="Phishing Investigation" )
phantom.comment(container,
f"URL flagged by {malicious_count} /{total_engines} engines. "
f"Requires analyst review." )
else :
phantom.set_status(container, "closed" )
phantom.comment(container,
f"URL clean: 0/{total_engines} engines flagged. Auto-closed." )
def hash_reputation_callback (action, success, container, results, handle ):
if not success:
return
for result in results:
data = result.get("data" , [{}])[0 ]
positives = data.get("summary" , {}).get("positives" , 0 )
if positives > 10 :
phantom.act("quarantine device" , targets=result,
assets=["crowdstrike_prod" ],
name="isolate_endpoint" )
phantom.set_severity(container, "high" )
def ip_reputation_callback (action, success, container, results, handle ):
if not success:
return
for result in results:
data = result.get("data" , [{}])[0 ]
malicious = data.get("summary" , {}).get("malicious" , 0 )
if malicious > 3 :
phantom.act("block ip" , targets=result,
assets=["palo_alto_prod" ],
name="block_malicious_ip" )
Step 3: Build Alert Enrichment Playbook Automate enrichment for all incoming SIEM alerts:
"""
Universal Alert Enrichment Playbook
Runs on every new event to add context before analyst review
"""
import phantom.rules as phantom
def on_start (container ):
success, message, artifacts = phantom.get_artifacts(
container_id=container["id" ], full_data=True
)
ip_artifacts = [a for a in artifacts if a.get("cef" , {}).get("sourceAddress" )]
domain_artifacts = [a for a in artifacts if a.get("cef" , {}).get("destinationDnsDomain" )]
for artifact in ip_artifacts:
ip = artifact["cef" ]["sourceAddress" ]
phantom.act("ip reputation" ,
parameters=[{"ip" : ip}],
assets=["virustotal_prod" ],
callback=enrich_ip_callback,
name=f"vt_ip_{ip} " )
phantom.act("geolocate ip" ,
parameters=[{"ip" : ip}],
assets=["maxmind_prod" ],
callback=geoip_callback,
name=f"geo_{ip} " )
phantom.act("whois ip" ,
parameters=[{"ip" : ip}],
assets=["whois_prod" ],
name=f"whois_{ip} " )
for artifact in domain_artifacts:
domain = artifact["cef" ]["destinationDnsDomain" ]
phantom.act("domain reputation" ,
parameters=[{"domain" : domain}],
assets=["virustotal_prod" ],
name=f"vt_domain_{domain} " )
def enrich_ip_callback (action, success, container, results, handle ):
"""Update container with enrichment data"""
if success:
for result in results:
summary = result.get("summary" , {})
phantom.add_artifact(container, {
"cef" : {
"vt_malicious" : summary.get("malicious" , 0 ),
"vt_suspicious" : summary.get("suspicious" , 0 ),
"enrichment_source" : "VirusTotal"
},
"label" : "enrichment" ,
"name" : "VT IP Enrichment"
})
Step 4: Implement Approval Gates for High-Impact Actions Add human-in-the-loop for critical actions:
def containment_decision (action, success, container, results, handle ):
"""Present analyst with containment options"""
phantom.prompt(
container=container,
user="soc_tier2" ,
message=(
"Confirmed malicious activity detected.\n"
f"Host: {container['artifacts' ][0 ]['cef' ].get('sourceAddress' )} \n"
f"Threat: {results[0 ]['summary' ].get('threat_name' )} \n\n"
"Select containment action:"
),
respond_in_mins=15 ,
options=["Isolate Host" , "Disable Account" , "Both" , "Monitor Only" ],
callback=execute_containment
)
def execute_containment (action, success, container, results, handle ):
response = results.get("response" , "Monitor Only" )
if response in ["Isolate Host" , "Both" ]:
phantom.act("quarantine device" ,
parameters=[{"hostname" : container["artifacts" ][0 ]["cef" ]["sourceHostName" ]}],
assets=["crowdstrike_prod" ],
name="isolate_host" )
if response in ["Disable Account" , "Both" ]:
phantom.act("disable user" ,
parameters=[{"username" : container["artifacts" ][0 ]["cef" ]["sourceUserName" ]}],
assets=["ad_prod" ],
name="disable_account" )
phantom.comment(container, f"Analyst approved: {response} " )
Step 5: Configure Playbook Scheduling and Triggers Set up event triggers in SOAR:
{
"playbook_name" : "phishing_triage_automation" ,
"trigger" : {
"type" : "event_created" ,
"conditions" : {
"label" : [ "phishing" , "notable" ] ,
"severity" : [ "high" , "medium" ]
}
} ,
"active" : true ,
"run_as" : "automation_user"
}
Step 6: Monitor Playbook Performance Track automation effectiveness with SOAR metrics:
import requests
headers = {"ph-auth-token" : "YOUR_SOAR_TOKEN" }
response = requests.get(
"https://soar.company.com/rest/playbook_run" ,
headers=headers,
params={
"page_size" : 100 ,
"filter" : '{"status":"success"}' ,
"sort" : "create_time" ,
"order" : "desc"
}
)
runs = response.json()["data" ]
total_runs = len (runs)
avg_duration = sum (r["end_time" ] - r["start_time" ] for r in runs) / total_runs
auto_closed = sum (1 for r in runs if r.get("auto_resolved" ))
print (f"Total runs: {total_runs} " )
print (f"Avg duration: {avg_duration:.1 f} s" )
print (f"Auto-resolved: {auto_closed} /{total_runs} ({auto_closed/total_runs*100 :.0 f} %)" )
