86 emph{\textbf{rundll32.exe}} could hint that the system has been compromised.\\

89 \ttfamily{volatility -f image1.vmem --profile=WinXPSP2x86 screenshot --dump-dir screenshots}\\
90 brings an image named \emph{\textbf{IMAGE1:/screenshots/session\_0.WinSta0.Default.png}} extracts an image containing an outline with a Message where DEP is closing Acrobat with an open file named \emph{\textbf{navy procurement.pdf}}.\\
91 This could hint at a compromised PDF.\\
93 The TCP-LISTEN on port 1031 seems to be used by malware as described by \url{http://de.adminsub.net/tcp-udp-port-finder/1031} or \url{http://www.auditmypc.com/tcp-port-1031.asp}.\\
