Credential Dumping Investigation

Based on the credential dumping alert from Step 1, perform a detailed technique analysis.

1. Map the technique to MITRE ATT&CK:
   - Primary technique (e.g. T1003.001 — LSASS Memory)
   - Sub-techniques if applicable
   - Associated tactics (Credential Access, Privilege Escalation, Lateral Movement)

2. Identify what credentials are at risk:
   - NTLM hashes (pass-the-hash risk)
   - Kerberos tickets (pass-the-ticket / golden ticket risk)
   - Plaintext credentials (WDigest enabled?)
   - Service account credentials
   - Domain Admin credentials

3. Assess post-exploitation risk:
   - Can dumped credentials enable lateral movement?
   - Can they enable privilege escalation?
   - Is Domain Controller compromise possible?
   - What systems are reachable with these credentials?

4. List top 3 false positive scenarios for this specific alert.

Output format:
MITRE ATT&CK MAPPING
| Tactic | Technique ID | Technique Name | Confidence |

CREDENTIALS AT RISK
| Credential Type | Risk | Impact if Compromised |

POST-EXPLOITATION RISK
- Lateral Movement: Yes / No / Unknown — [reason]
- Privilege Escalation: Yes / No / Unknown — [reason]
- DC Compromise Risk: Yes / No / Unknown — [reason]

FALSE POSITIVES
1. [scenario]
2. [scenario]
3. [scenario]

Base everything on the actual alert data provided.

Generate a targeted investigation and containment checklist for this credential dumping alert.

For each checklist item provide:
- Exact log source to check
- Specific event IDs or field values
- What malicious looks like vs benign

INVESTIGATION CHECKLIST:

1. Process Investigation
   - Review full process tree (parent → child)
   - Check process execution path for anomalies
   - Verify process hash against known-good baseline
   - Event IDs: 4688 (process creation), Sysmon 1, 10 (process access)

2. LSASS Access Verification
   - Check which processes accessed lsass.exe
   - Look for OpenProcess with PROCESS_VM_READ on LSASS
   - Sysmon Event ID 10 — ProcessAccess targeting lsass.exe

3. Authentication Log Review
   - Check for new logon events after alert time (4624, 4625, 4648)
   - Look for lateral movement: remote logons from affected host
   - Check for Pass-the-Hash: NTLMv2 authentication anomalies

4. Network Activity
   - Outbound connections from affected host after alert
   - SMB connections to other hosts (lateral movement indicator)
   - Any C2 beacon patterns

5. Containment Actions (prioritise these)
   ⚠️ HIGH PRIORITY: Should affected host be isolated immediately?
   ⚠️ HIGH PRIORITY: Should affected credentials be reset immediately?
   - Force password reset for all accounts on affected system
   - Revoke active sessions and Kerberos tickets (klist purge)
   - If DC involved: consider krbtgt password reset

Also provide 3 SIEM queries to hunt for related credential dumping activity.
If SIEM tool is known, write queries for that tool.
If unknown, write generic logic with clearly labelled placeholders like [field_name].

Base everything on the actual alert data. Do not give generic SOC advice.

Write a professional SOC ticket summary for this credential dumping investigation.

Include:
- What the alert detected (one sentence)
- Whether it appears malicious, suspicious, or benign and why
- The key evidence supporting that conclusion
- Recommended next action and who owns it
- Whether immediate containment is required

Length: 3–5 sentences maximum.
Format: suitable for pasting directly into a SIEM ticket or incident log.

Severity: Critical / High / Medium / Low / Informational
Disposition: True Positive / False Positive / Needs Investigation
