+Lateral Movement - Pass the Hash
+
+**(P) Preparation**
+
+1.  Patch asset vulnerabilities
+2.  Perform routine inspections of controls/weapons
+3.  Ensure Antivirus/Endpoint Protection software is installed on workstations
+4.  Ensure that servers and workstations are logging to a central location
+5.  Network segmentation and firewalls can help reduce impact
+6.  Disable NTLM authentication where possible  
+    a. SMB  
+    b. HTTP  
+    c. SMTP
+
+**(I) Identification**
+
+1.  Monitor for:  
+    a. Unusual user activity  
+    b. Unexpected logins using NTLM
+2.  Investigate and clear ALL alerts associated with the impacted assets
+
+**(C) Containment**
+
+1.  Inventory (enumerate & assess)
+2.  Detect | Deny | Disrupt | Degrade | Deceive | Destroy
+3.  Observe -> Orient -> Decide -> Act
+4.  Issue perimeter enforcement for known threat actor locations
+5.  Lock accounts suspected of having a compromised hash
+6.  Systems believed to have malware on them should be removed from the network
+
+**(E) Eradication**
+
+1.  Close the attack vector
+2.  Patch asset vulnerabilities
+3.  Perform Endpoint/AV scans on the systems of affected users
+4.  Review logs to identify other potential cases of passing the hash
+
+**(R) Recovery**
+
+1.  Restore to the RPO within the RTO
+2.  Address collateral damage
+3.  Change the passwords of any potentially compromised accounts
+4.  Determine the chain of events that led to the pass the hash incident
+5.  Resolve any related security incidents
+
+**(L) Lessons/Opportunities**
+
+1.  Perform routine cyber hygiene due diligence
+2.  Engage external cybersecurity-as-a-service providers and response professionals
