+            \item SkyLined's Alpha2 x86 alphanumeric encoder

+        \item Payload encoders generally taken for granted
+        \begin{sitemize}
+            \item Most encoders use a static decoder stub

+    \begin{sitemize}
+        \item NOP generation hasn't publicly changed much
+        \begin{sitemize}
+            \item Most PoC exploits use predictable single-byte NOPs (\texttt{0x90}), if any
+            \item ADMmutate's NOP generator easily signatured by NIDS (Snort, Fnord)
+            \item Not considered an important research topic to most
+        \end{sitemize}
+
+        \pause
+        \item NIDS continues to play chase the tail
+        \begin{sitemize}
+            \item The mouse always has the advantage; NIDS is reactive
+            \item Advanced NOP generators and encoders push NIDS to its limits
+            \item Many protocols can be complex to signature (DCERPC fragmentation)

+            \item Linux/BSD/Solaris techniques are largely unchanged
+            \item Windows heap overflows can be made more reliable (Oded/Shok)
+            \item Windows SEH overwrites make exploitation easy, even on XPSP2
