 ## Obfuscation
 
+* Deliberate act of creating obfuscated code that is difficult for humans to understand
+* Plain text strings will appear as base64 or Xor
+* Malicious behavior will include junk functions or routines that do nothing to throw off the reverser.
+    * Control-Flow Flattening
+    * String Encryption

+
 ## Persistence 
 
+* Once malware gains access to a system, it often looks to be there for a long time. 
+* If the persistence mechanism is unique enough, it can even serve as a great way to identify a given piece of malware.

+## Privilege Escalation
 
-## Defense Evasion    
+* Exploiting a bug, design flaw or configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user.
+* Common Techniques:
+  * Dll Search Order Hijacking
+  * Dll injection
+  * Exploiting a vulnerability
+    * BufferOverflow
+    * StackOverflow
+    * Headspray
+    * Return Orientated Programming (ROP)
+  * Credential Theft
+  * UAC Bypasses
+
+Example: Dll Search Order Hijacking

+
+## Defense Evasion   
+* Evading detection or avoiding defenses.
+* Common Techniques:
+  * Killing AV
+  * Deleting itself after a run
+  * Timebombs/Timestomping
+  * Stolen Certificates
+  * Dll Side Loading
+  * Masquerading
+  * Process Hallowing
 
 ## Credential Theft
 
+* Going after password storage
+* Keylogging passwords
+* Screenshots
+
+Example: Mimikatz credential theft
